Warnings Pay particular attention to the following warnings encountered in the pages of the

BECSys5 Installation and Technical Manual:

Warning: Various other warning boxes may be found throughout the manual text.

Caution: Various caution boxes may be found throughout the manual text.




Unpacking Your Shipping package should contain these items: A. The BECSys5 Controller B. ORP Sensor C. pH Sensor D. Temperature Sensor E. Flow cell Kit F. Rotary or Reed flow switch G. This manual (not shown) H. BECSys for Windows Installation CD (not shown) I. Optional sensors (not shown) A B C D E F

General Guidelines Proper installation and use of the BECSys controller depends on the specific needs of the application. Read the manual completely before starting the installation and ensure all guidelines and recommendations are followed. All components should be mounted and the flow cell plumbing installed and pressure tested before wiring the controller. Ensure compliance with all applicable plumbing and electrical codes during the installation as well.

Firmware Version This manual was written for firmware v1.46. If you received newer firmware but did not receive a copy of the manual covering that version of firmware, please contact your distributor.

Warning: The ORP and pH Sensors are very fragile and must be handled with care. The tips of the probes must be kept wet at all times, requiring the wetting caps to remain in place until they are ready to be

installed. The probes must be stored in temperatures above freezing.

Reed

or

Caution: The BECSys controller should not be installed where it is accessible to the public.




Environmental Conditions The BECSys5 is housed in a NEMA 4X (IP65) enclosure. It should not be used in explosive environments. The BECSys5 should be mounted so that adequate ventilation is provided around the enclosure, preventing general environmental specifications from being exceeded (see table below).

Section A: Mounting the BECSys5 Controller

A – 1: Mounting the Controller The BECSys5 Controller and flow cell are mounted separately. The BECSys5 enclosure should be mounted to the wall with four anchor bolts. To mount the BECSys5 properly, please use the included mounting template and hardware. Drill the holes for the anchors using a 3/16” drill bit. Install the anchors in the wall. Remove the lid from the unit and place the included screws in the four corners of the box. Attach the screws into the anchors. The BECSys5 and flow cell should be mounted in a location that is free from chemical fumes and excessive heat, isolated from electrical interference, and near a power source protected by a ground fault interrupter. The BECSys5 has a NEMA4 weather resistant enclosure but should still be protected if mounted outdoors.

A – 2: Wrapping the Fittings If you are assembling a flow cell, first open the bag of flow cell fittings and wrap each fitting two times around clockwise with Teflon tape.

A – 3: Assembling the Flow cell Assemble the flow cell as shown below:

When installing the pH or ORP sensor, remove the wetting cap, then remove any existing Teflon tape from the sensor threads. Re-wrap the threads with new Teflon tape. Rinse the sensor tip in de-ionized water and install as shown.

A – 4: Plumbing the Sample Stream Install the sample stream; ½-inch tubing is recommended for sample stream pickup and return. Make sure that you tap the supply off the discharge side of the recirculation pump, upstream of the chemical injection points. The sample should be filtered water. Connect the sample stream pickup line to the flow cell and run the sample stream return line from the flow cell to the suction side of the main recirculation pump. Install ½-inch ball valves to allow isolation of the sample lines.

Warning: These sensors should be hand-tightened only. Tools are not necessary for

installing the pH or ORP sensor and will damage the sensor housing.




A – 5: Chlorine Sensor Flow Cell

Your controller may have been ordered with either a CCS140 Free Chlorine Sensor or a CCS140 Free Chlorine Sensor and a Total Chlorine Sensor. These sensors are mounted in a flow cell which includes a flow and psi restrictor assembly shown below:

Both sensors require a constant flow rate and constant pressure. This helps ensure that the ppm levels will remain stable.

Here is the recommended method for plumbing the free chlorine sensor flow cell:

Admission pressure must be above the regulated pressure (15 psi is the limit on the sensors). Run the sample stream through a flow restrictor valve (to maintain flow rate, minimum flow rate requirement is 8 gph). Take the stream through the flow cell. Discharge the sample stream to a free outlet (for example into a surge tank).

A – 6: Sensor preparations NOTE: As soon as you install the sensors, immediately move on to the next step to ensure that they always stay wet. A – 6.1: ORP and pH Sensor The pH and ORP sensors are shipped with a

wetting cap covering the measuring end. This cap contains a solution of pH 4 buffer saturated with potassium chloride (KCl). Gently remove the wetting cap by unscrewing the sensor and sliding the cap off of the sensor body.

It is a good idea to save the wetting cap and the box that the sensor came in for future long-term storage.

During shipping, the air space inside the pH glass may have moved into the bulb. Grasp the sensor near the cable end and gently swing it through an arc to force the internal electrolyte into the pH bulb. Rinse the measuring ends of potentiometric sensors with de-ionized or distilled water before installation into a flow cell.

A – 6.2: Free Chlorine Sensor The Free Chlorine Sensor is supplied with a yellow protective cap. This cap has an inner sponge that is used to keep the sensor membrane hydrated. This cap should be saved for long-term storage. Insert the sensor in the left position of the flow cell. Wrap the threads of the retaining nut with Teflon tape. Slide the retaining nut over the cable and hand tighten. The sensor can remain in the flow cell for short-term interruptions in measurement. To prevent membrane dehydration, the flow cell must not drain off. If this is not ensured, then remove the sensor from the flow cell and slide the yellow protective cap, moistened at the inner sponge, onto the measuring end of the sensor. The voltage applied by the controller to the Free Chlorine Sensor polarizes the surface of the gold cathode. The polarization period must elapse before calibration is performed based on the results acquired through the use of a DPD test kit. See Section H - 2.3 for filling the electrolyte.

Caution: Amperometric chlorine sensors require the use of a temperature sensor and a properly calibrated pH sensor. Refer to the instruction pamphlet included with the

sensor at the time of installation.

Warning: Negative pressure will damage the sensor membrane.



Installation and Technical Manual Rev: G12 A – 6.3: Total Chlorine Sensor

If your controller was ordered with a Total Chlorine Sensor, the following steps must be followed for installation. The Total Chlorine Sensor does not ship with Electrolyte inside the sensor chamber; it must be filled before installation. The lower portion (below the upper band) unscrews. Be sure to lift the hose ring that covers the vent while removing the membrane cap. Fill the membrane cap to the edge with the electrolyte. Make sure there are no bubbles. Insert the sensor into the membrane cap. Slowly screw the membrane cap onto the sensor. Excess electrolyte will escape through a valve in the membrane cap – do not block this valve. Rinse excess electrolyte off with water. Included with the Total Chlorine Sensor are: the Total Chlorine Sensor, the cable, two O-Rings, a probe ring, and the O-Ring retainer and the Probe Nut.

The Probe Ring is installed first. Slide the smaller diameter O-Ring up the sensor body until it rests against the Probe Ring.

Insert the larger diameter O-Ring into the O-Ring retainer. Slide the O-Ring retainer (O-Ring side towards membrane) up against the O-Ring just installed. Insert the complete assembly into the Flow Cell. Wrap the threads of the Probe Nut with Teflon tape. Use the Probe Nut to secure the sensor inside the Flow Cell. The top of the Probe Nut should be at the bottom of the label.

Attach the cable to the top of the Total Chlorine Sensor. The cable and the top of the sensor are keyed. Once the pins are engaged, tighten the cable to the sensor. The voltage applied by the controller to the Total Chlorine Sensor polarizes the surface of the gold cathode. The polarization period (one hour) must elapse before calibrations are performed.

After wiring the sensor to the controller (see section B) and assigning the input, perform the following calibrations:

Two calibrations are required at installation.

1) Shut off the sample stream, drain the flow cell, and then flush and fill it with distilled water. Wait the hour polarization period before calibrating the input, entering 0 ppm for the value. You can calibrate the free chlorine to 0 at this time as well.

2) After the zero point calibration is done, you can open the sample stream valve and wait at least 15 minutes before calibrating again with the results acquired through the use of a DPD test kit. The second calibration should be done with flowing water with at least 2.5 ppm total chlorine.

Warning: The membrane may be damaged if the vent is not opened while removing the

membrane cap.

Warning: Never touch the electrode finger.




A – 7: Opening the Sample Stream Valve Open the sample stream valve and check for leaks. Note the reading on the compound pressure gauge and make sure that it shows a positive and steady pressure. The sample stream should be about 2-20 psi at the flow cell. If this is not the case, then adjust the valves or relocate the point at which the sample stream is connected to the recirculation system. Negative pressure will destroy the sensors. Once you have a positive and steady pressure, open the wet test valve and make sure that it generates a vigorous stream.

A – 8: Plugging in the Sensors Remove the protective covers from the BNCs. Plug the pH sensor into the coded BNC jack and the ORP sensor into the coded BNC jack on the bottom of the BECSys5 controller by twisting them a quarter of a turn. Allow the sensors to rinse in the sample water while you do the wiring (Section B).




Section B: Wiring the BECSys5 Controller

B – 1: Opening The Cover

Remove the cover by loosening the four screws at the corners with a screwdriver as shown. NOTE: The screws are captive and do not need to be totally removed, but only loosened. Once the screws are loosened, carefully lift the top cover off of the unit. The cover will still be connected to the base by the ribbon cable. Set the moisture absorbent packet found inside aside for now.

We recommend that you disconnect the ribbon cable by spreading the two holders at the end of the cable attached to the cover as shown, unplug the cable and remove the cover. NOTE: Be sure to store the cover in a safe, dry place while you wire the unit.

B – 2: Removing the safety shield To remove the shield, remove the four screws using a Philips screwdriver. Gently lift the cover straight up and set it to the side.

B – 3: Supplied Cords You may order your controller with a male power cord and two female power cords (Only for 115V applications). Plug the male AC Cord into a GFCI outlet and connect the chemical feeders to the female power cords. The two female power cords will have the following warning tags. Be sure to connect the correct female power cord to the correct chemical feeder.

Warning: Make sure power is disconnected while you wire the unit




B – 4: Conduit Connect You may instead order the controller for conduit connection (For 115V or 230V applications). TB4 is for the Line power coming into the unit.

We recommend using a minimum of 14 gauge stranded wire for the line power. Use of solid wire is strongly discouraged. The black wire goes to L (Line) on the upper level, the white wire to N (Neutral), and the ground wire to the terminal marked Earth Ground. NOTE: The black and white wires are colored brown and blue outside North America.

B – 5: Relay Wiring The BECSys5 has four solid-state relays. From the Factory, the controller is configured to use Relay 1 for the pH Feed and Relay 2 for the ORP/Cl/Br Feed. The rest of the relays are unassigned. Each relay can be powered from either the L (Line) terminal that the controller itself is powered from, or from the common terminals. Relay 1 and 2 share a common (labeled C1 C2), Relays 3 and 4 have their own common labeled C3 and C4 respectfully. As shipped from the factory, all four relays are configured for Line power.

B – 5.1: Externally Powered Wiring

If you wish to use the C (Common) to power a relay (commonly used to interlock feeds with the recirculation pump), you will need to move the black hat jumpers located to the left of each of the solid state relays to their upper position using a pair of long nosed needle nose pliers (shown left). Be careful not to put pressure on the relays as you are slipping between them as you may damage their connections to the board.

B – 5.2: Relay 1

B – 5.2.1: Line Powered Wiring The black wire goes to the R1 position, the white wire goes into any of the unused N (Neutral) positions, and the Earth Ground wire goes to any of the unused Earth Ground positions.

Note: The black and white wires are colored brown and blue outside North America.

Hats shown in L (Line) positions

Hats shown in C (Common) positions


Warning: Unless specified at time of order, controllers are configured for 110VAC and will not work on 220VAC. Hooking up to 220VAC will damage the controller and is not covered

under warranty.




Installation and Technical Manual Rev: G12 B – 5.2.2: Externally Powered

Move the hat jumper to the upper position. Connect the power supply to the C1 C2 terminal. The load should be connected to the R1 position. If Earth and Neutral are involved in this circuit, these can be wired into any of the unused N (Neutral) positions, and Earth Ground positions.

B – 5.3: Relay 2



B – 5.3.2: Externally Powered Move the hat jumper to the upper position. Connect the power supply to the C1 C2 terminal. The load should be connected to the R2 position. If Earth and Neutral are involved in this circuit, these can be wired into any of the unused N (Neutral) positions, and Earth Ground positions.

B – 5.4: Relay 3



B – 5.4.2: Externally Powered

Move the hat jumper to the upper position. Connect the power supply to the C3 terminal. The load should be connected to the R3 position. If Earth and Neutral are involved in this circuit, these can be wired into any of the unused N (Neutral) positions, and Earth Ground positions.



Installation and Technical Manual Rev: G12 B – 5.5: Relay 4



B – 5.5.2: Externally Powered

Move the hat jumper to the upper position. Connect the power supply to the C4 terminal. The load should be connected to the R4 position. If Earth and Neutral are involved in this circuit, these can be wired into any of the unused N (Neutral) positions, and Earth Ground positions.

B – 6: Relay Expansion Module Wiring Your controller may have been ordered with one or more Relay Expansion Modules (BECSysMRX or BECSysSRX). No more than three relay expansion modules can be connected to one controller. B – 6.1: Power Wiring We recommend using a minimum of 14 gauge stranded wire for the line power. Use of solid wire is strongly discouraged. The black wire goes to Line, the white wire to the Neutral position, and the ground wire to the terminal marked Earth Ground. NOTE: The black and white wires are colored brown and blue outside North America.

B – 6.2: RS485 Wiring Wire the relay module’s RS485 to the RS485 terminal inside the BECSys5. Connect “A” to “A”, “B” to “B”, and “Shield” to “Shield.” Recommended wire: 22 gauge shielded twisted pair (1 pair: 2 conductors + shield). For outdoor use, use NEC type PLTC. For indoor use, use NEC type CMG general, CMR riser (through floors), or CMP plenum as required by the local wiring code. The modules have a second RS485 connector to allow daisy chaining of units. It doesn’t matter which connector you use – whichever is easiest. For each unit, connect “A” to “A”, “B” to “B”, and “Shield” to “Shield.” B – 6.3: Setting Dip Switches

Located on the left hand side of the modules are two dipswitch banks. One sets the Controller ID, the other sets the Relay Box ID. The Controller ID should always be set to 1 – turn on switch 1 of the “CntrID” bank. Each Relay Expansion Module should have a different Relay Box ID – set by the “RlyBoxID” bank. The IDs can be from 1 to 3 – turn on the corresponding dipswitch to set the ID.

B – 6.4: Wiring the relays Each relay can be powered from either the Line terminal on CN2 that the module itself is powered from, or from the COM (common) terminal on each relay's connector block. As shipped from the factory, all five relays are configured for Line power. If you wish to use a common to power a relay, you will need to move the black hat jumpers located below the fuses to its upper position. The picture below shows the hat jumpers in the default line positions on an SRX.

Warning: Unless specified at time of order, modules are configured for 110VAC and will

not work on 220VAC. Hooking up to 220VAC will damage the module and is not covered

under warranty.




B – 7: Flow Switch Wiring A flow switch must be used in the operation of a BECSys5 Controller A paddlewheel flow switch or reed flow switch must be incorporated into the flow cell to disable chemical feed in the event of loss of flow to the flow cell.

B – 7.1: Paddlewheel Flow Switch

Connect the black wire of the paddlewheel/rotary flow switch to the terminal marked ground, the white wire to the terminal labeled IN, and the red wire to the terminal labeled + 12. The green “flow” light on the flow switch will light whenever flow is present.

B – 7.2: Reed Flow Switch

The reed flow switch is a (2) two-wire switch. Connect the black wire to the terminal labeled IN, and the red wire to the terminal labeled + 12. NOTE: Unlike the paddlewheel flow switch, the reed flow switch is a directional switch. Make sure it is installed with the flow arrow in the proper direction. No check valve is required with the reed flow switch.

B – 8: Amperometric Probe Wiring

Connect the red "A" wire to the A terminal, the "K" white tip with transparent wire to the K terminal, and the thick unlabeled wire to the ground terminal. NOTE: This probe requires a minimum flow velocity of 15 cm/s against its membrane. If the default calibration is off more than 0.3 ppm, the flow rate may be too low. Contact the factory for assistance.

B – 9: Temperature Sensor Wiring

Connect the temperature probe to the Temp terminals. The temperature probe is non-polarized, wire orientation does not matter.

Warning: A check valve is must be installed with the paddlewheel flow switch to prevent backflow when the system is shut down. If a

check valve is not installed, backflow could give the controller a false reading of flow and continue to pump chemicals into the pool.

Warning: NEVER BYPASS FLOW SWITCH CONNECTIONS

The Flow Switch is a critical safety device which prevents uncontrolled chemical feed.

Uncontrolled feeding of chemicals can result in injury or death.

Warning: Failure to incorporate a Flow Switch and Flow cell into the sample

stream of your BECSys chemical controller can result in injury or death to swimmers in or

around the pool if the recirculation pump should fail or shut down.




B – 10: Flow Meter Wiring B – 10.1: +GF+Signet 2536 (Blue Cap)

Connect the black wire to the +12 terminal, the red wire to the IN terminal, and the silver wire to the ground terminal. Set SW1 switches 6 = off, 7 = on. B – 10.2: +GF+Signet 515 (Red Cap)

Connect the red wire to the IN terminal and both the black wire and the silver wire to the ground terminal. Set SW1 switches 6 = on, 7 = off. B – 10.3: +GF+Signet 2551 Magmeter

The magmeter must be configured for frequency output and the pipe size jumper must be set as described in the magmeter's operation manual. A 10K resister installed across pins 1 & 2 is not needed.

Connect pin 1 to the +12 terminal, pin 2 to the IN terminal, and pin 3 to the ground terminal. Set SW1 switches 6 = off, 7 = on (same as blue cap).

B – 11: Conductivity Wiring You may order the BECSys5 with an optional Conductivity Input Board.

Connect the conductivity probe to the Cond terminals. The Conductivity probe is non-polarized (wire orientation does not matter).




B – 12: 4-20mA and Digital Input Wiring The standard BECSys5 input board comes with four 4-20mA/digital inputs (outlined in red) labeled pH Inv, Cl Inv, CH3, and CH4. Each input has a + and – terminal and be configured as either a 4-20mA input or a digital input by setting the corresponding dipswitch for that channel (outlined in blue). Dip 1 (the left most switch) sets the pH Inv labeled input, dip 2 sets the Cl Inv labeled input, and so on. The input is a 4-20mA input when the switch is up, and a digital input when the switch is down.

You may need to re-assign an input to one of the physical 4-20mA/digital inputs in the firmware. See “Re-assignable Inputs” in section C for more information. Each input can be configured as either a 4-20mA input or a digital input by setting the corresponding dipswitch for that channel. The input is a 4-20mA input when the switch is up, and a digital input when the switch is down. Input Type “pH Inv” 4-20mA/digital Dip 1

Dip

“Cl Inv” 4-20mA/digital Dip 2 “CH3” 4-20mA/digital Dip 3 “CH4” 4-20mA/digital Dip 4 The following sections describe how to wire each device to an input without specifying which input to wire too, but lists the input the controller defaults to using if it has one. In the case where an input function has no default input, it is up to the installer to choose one of the unused inputs to wire to, then program the controller to use that physical input for that input function (MenuInputsReassign Inputs). If you connect the device to the pre-labeled input on the BECSys5, you will not need to re-assign inputs.

B – 12.1: BECSysLS

A BECSysLS may be used to monitor the following liquid levels: pH Inventory Cl/Br Inventory Water level (Surge/Balance pit/tank)

The BECSysLS is a 4-20mA input and requires the Loop Power Supply Board. Connect this sensor to the selected 4-20mA/digital input on the BECSys5 as follows:

Make sure you configure the input for 4-20mA by switching the input’s dip switch to the upper position.

Controller Wiring

B – 13: 4-20mA Output Wiring Your controller may have been ordered with one or two 4-20mA output boards. Using this you can connect the controller to a building management system or other device. You would connect the “+” on the 4-20mA output board

to the “+” on the device and the “-“ on the 4-20mA output board to the “-“ on the device.




B – 14: BECSysRPM (Remote Probe Module) Your controller may have been ordered with a BECSys Remote Probe Module Interface Board. Using this, you may connect to a BECSys Remote Probe Module (BECSysRPM). The BECSysRPM provides a method of extending the probe signal. B – 14.1: Wiring the BECSysRPM:

Remove the cover of the BECSysRPM by loosening the four screws at the corners with a screwdriver. Note: The screws are captive and do not need to be totally removed, but only loosened. Once the cover has been removed, you will see two sets of connectors. The left bank of connectors provides connection between the BECSysRPM and the BECSys5. The right bank of connectors provides connection for the Flow Switch and Temperature Sensor.

Wiring the Temperature Sensor: Connect the Temperature Sensor to the RTD-IN + and RTD-IN – connectors on the right bank. The Temperature Sensor is non-polarized, wire orientation does not matter.

Wiring a Paddlewheel Flow Switch: Connect the black wire of the paddlewheel/rotary flow switch to the terminal labeled GND, the white wire to the terminal labeled Flow, and the red wire to the terminal labeled +12V. The green “flow” light on the flow switch will light whenever flow is present.

Wiring a Reed Flow Switch: The reed flow switch is a two wire switch. Connect the black wire to the terminal labeled “FLOW” and the red wire to the terminal labeled “+12V”.

NOTE: Unlike the paddlewheel flow switch, the reed flow switch is a directional switch. Make sure it is installed with the flow arrow in the proper direction. No check valve is required with the reed flow switch.

Connecting the Probes: Remove the protective covers from the BNCs. Plug the pH sensor into the coded BNC jack and the ORP sensor into the coded BNC jack on the bottom of the BECSysRPM by twisting them a quarter of a turn.

B – 14.2: Wiring to the BECSys5: There are a total of seven connections that must be made between the BECSys5 and the BECSysRPM (24 gauge wire is acceptable to use).

Power: Power is provided to the BECSysRPM from the BECSys Remote Probe Module Interface Board. Connect the terminal labeled +12V on the BECSysRPM Interface Board to the terminal marked +12V on the BECSysRPM (left bank of connectors). Connect the terminal labeled GND on the BECSysRPM Interface Board to the terminal marked GND on the BECSysRPM (left bank of connectors).

Probe Signal: From the BECSysRPM Interface Board connect the terminal labeled Out(1) to Out(1) on the BECSysRPM. Connect Out(2) to Out(2) on the BECSysRPM.

Flow: On the BECSys5 CPU board, connect a wire to “IN” on the Flow Switch Input. Connect the other end to the terminal labeled “FLOW” on the BECSysRPM. The +12V and GND on the BECSys5 Flow Switch Input are not used.

Temperature: From the BECSys5 Input Board, connect two wires to the “Temp” input. Connect the other end of these two wires to the terminal labeled “RTD-OUT +” and “RTD-OUT –“. The temperature input is not polarized, wire orientation does not matter.

Warning: A check valve is must be installed with the paddlewheel flow switch to prevent backflow when the system is shut down. If a check valve is not installed, backflow could give the controller a false reading of flow and continue to pump chemicals into the pool.




B – 15: BECSys Ethernet Board Use these wiring instructions for controllers that come with a BECSys Ethernet board installed at the factory. If you are installing a BECSys Ethernet board into a controller yourself, use the instructions supplied with the BECSys Ethernet board instead of these. Connected to the end of the network cable is an in-line coupler. You may either connect a cable directly to this or remove the coupler and connect to a wall jack.

B – 16: Re-installing the safety shield

Gently place the safety shield over the fuse holders – you may have to adjust the fuse holders a little in order for it to fit properly. Once the shield is sitting flat, replace the four screws.

B – 17: Fuses 115VAC Model (F4):

¼ Amp 250V Time Lag Fuse (¼” x 1¼”) 230VAC Model (F4):

⅛ Amp 250V Time Lag Fuse (¼” x 1¼”) Relay Fuses (F1 – F4):

3 Amp 250V Time Lag Fuse (¼” x 1¼”) RS485 Fuse (F11 CPU Board):

¼ Amp 250V Time Lag Microfuse (5.08mm)

Warning: The controller must be connected to a Standard Ethernet Port. Connecting to a Power Over Ethernet (POE) Port will cause damaged to

the controller.




Section C: Programming the Controller

C – 1: Adjusting the Display Contrast You can adjust the display contrast by holding down either the up or down arrow keys for two seconds, then after the controller beeps three times, use the up and down keys to adjust the contrast.

C – 2: Security Settings C – 2.1: Access Codes and levels

The BECSys5 controller ships from the factory with all access codes disabled. The controller will not ask you for an access code when you press the menu or other quick buttons until you enable and set the Rep access code and at least one Operator access code. Setting Manager access codes is optional. If the Rep access code is disabled, you are automatically given rep access without the controller prompting you for an access code. This is true even if you set an Operator and/or Manager access codes. To view who is currently logged on, press the lock screen button while in any menu.

The Main Menu will also display who is logged on along with the version of firmware. You do not need to set all the access codes for each level if you do not wish to. Also, a disabled access code is not equivalent to 000, so entering 000 when it prompts for an access code will only work if you have specifically assigned an access code to be 000.

NOTE: Once access codes have been set, certain programmable options will not be accessible to Operators and Managers.

Until you set the rep access code, you will always have rep access, and until you set at least one operator code, the controller will never prompt you to enter an access code to gain access to a particular screen (see table).

Rep Managers Operators Access level given

Not set Don't care Don't care Rep Set Not set Not set Manager Set 1 or both set Not set Operator Set Don't care 1 or more set Prompt

Setting just the rep access code will result in the default access level being Manager, and the controller will still not prompt you

C – 2.2: Setting Access Codes

to enter in an access code when you press the Menu or other face panel buttons. However, any items exclusive to rep access will not be shown unless you log on manually via the Logon selection in the main menu.

To set an access code, press the menu button, then:

Select System Config Choose User Setup Then select the access level you want to set an

access code for. To set Operator 1's access code, you would select Oper. Access Codes, then select Operator 1.

Pressing and holding the +/- button disables the access code, while pressing enter will enable and set the access code to the value on the screen. Operators may only change their own access code. Managers may change their access code and any of the Operators. Reps can change anyone's access code.

Warning: It is strongly recommended to set a Rep Access Code. By not setting a Rep Access

Code, anyone can access Rep Menus.



Installation and Technical Manual Rev: G12 C – 2.3: Recovering Lost Access Codes

If an access code is forgotten, the code can be recovered by the following procedure:

1. Flip switch 2 on SW1 to the on position.

2. Press Menu, and if necessary select logon to

bring up the Access Menu.

3. Select the level of the access code you wish

to recover. 4. Record the encrypted value(s) displayed

beneath the prompt and turn Dip 2 off when done. The example below shows the encrypted codes for Op1 (D), Op3 (F), and Op4 (G), while Op2, Op5, & Op6 are disabled on that system.

5. BECS Technology can be contacted for

decryption of this code, providing the original access code.

C – 2.4: Setting Permissions You may set what operators, managers, or anyone have access to in the Permissions menu. By default, all permissions are set to their lowest level (Oper, Mgr, & Rep or Anyone). When you select the Permissions menu under the User Setup menu, you are given several options to choose from. By selecting one of these options you are able to select who has access to what. If “Oper, Mgr & Rep” is selected, everyone with an access code is able to modify that setting. If “Mgr & Rep” is selected, only Managers and Reps are able to modify the settings. If “Rep only” is selected, only Reps are able to modify the setting.

If you set the permissions for Calibrations, when you press the Cal button while in the normal display, the unit will display the current enabled inputs. Once you select input to calibrate, you will then be prompted to log into the controller. If you do not have permission to change the value, “Access level denied” will be displayed in the status area. A third permission level is set up for Emergency Off and Reset Fail/Safe. This level is “Anyone” and is the default setting. If the permission setting is “Anyone”, you may access these functions without logging onto the controller.

C – 3: Navigating the menus The controller's menus incorporate built in help text to aid in understanding the function of each parameter, item, and option. C – 3.1: Common status messages

The very bottom line of the display contains the time and date on the left while the right is reserved for a number of status messages; the most common are as follows:

"Busy..." - Indicates the controller is busy doing something critical and it cannot stop until it finishes. Until this message disappears, the controller will not respond to your key presses (although it does record them any will process them when done). Normally this message is only seen briefly after changing a setting, but it is also used for lengthier operations such as factory defaults and in the extremely rare case where the internal diagnostics detect a memory problem and attempts to correct it.

"(1 of 2) (More )" - and the like indicate there are more options for you to choose from than the controller could show at one time. Press the right arrow key (Next) to view them. The left number indicates the current page, while the right number indicates the total number of pages.

"Bad Value, Retry..." - Accompanied by an error beep, this indicates the value you just entered was not within the allowable range of values and was not stored.

Warning: Interrupting the controller by turning the power off while it displays the busy message could result in the complete loss of all

of its settings.



Installation and Technical Manual Rev: G12 C – 3.2: The Menu Screens

Most of the features of the controller are configured via the Menu button's menus. The menu screens can be broken up into two types: entry screens and lists.

C – 3.2.1: Entry Screens An entry screen is used to enter a value using the keypad.

The current value is usually displayed at the top while the cursor will be positioned under the current digit or character of the value you are entering in. The up and down arrows allow you to move the cursor right or left so you do not have to retype the existing digits if you only wish to change one. Most numerical values will display the minimum and maximum values you can enter in at the bottom of the display in the format "< ### to ###>". These ranges many times will be dependant on other values you have set, such as alarm points or set points, while others are simply fixed to stay within a reasonable range. Entering a value that is not within the acceptable range will result in an error beep and the message "Bad Value, Retry..." being displayed in the status area. For some values, certain keys may take on special functions that are explained in the lower lines of the screen. The Down/up message in the example above is one of them.

C – 3.2.2: List Screens The list screens are mainly composed of lists of menu items that you can choose from by either pressing an item's number or by using the up and down arrow keys to select it (indicated by the arrow) and then pressing enter to choose it. Using the up and down arrow keys also allows you to view each item's help text. And if the item leads to an entry screen or a list screen that sets a setting (see below), the current value is displayed in the lower right side.

Lists can also be used to change a setting:

When a list is used this way, it will display the current setting followed by the words "Change to:". Because it is a list, you can select an item with the up/down buttons to see help information about that particular selection.

There are a few list screens that use the entire width of the display for displaying values associated with each item and therefore do not have help. See Section E: Using the Quick Set Face Panel Keys for examples of these types of screens.



Installation and Technical Manual Rev: G12 C – 3.3: The Lock Screen Key

When not in a menu (i.e. viewing the normal display), pressing the lock screen key will prevent the controller from paging the screen to show more inputs, alarms, and other status information. See Section D: The Normal Display for more info about using the lock screen key in the normal display. While within any menu, if the user does not press a key within sixty seconds of the last key press, the current user is logged out and the screen is returned to the normal display. To prevent the controller from timing out, you may lock the screen. While within a menu, pressing the Lock Screen key will bring up a popup menu:

The first option on the popup will be either to lock or unlock the screen depending on the current lock state. While the screen is locked, key presses normally are ignored. However, in some instances certain keys are given special functions while the screen is locked, such as using the up and down arrows to scroll the help text if all of the help text cannot be displayed at once.

You can also lock/unlock the screen without bringing up the popup menu by holding down the lock button for one second. The controller will acknowledge this action with a triple beep and the yellow Lock Screen light will turn on.

The Lock button popup menu also identifies who is currently logged on, and provides an option for the user to log off. You can also select cancel if you pressed the lock button in error.




C – 4: Inputs To enter the program menu, press the Menu button on the front face panel of your controller. This will allow the viewing of the Main Menu where the programming options are displayed.

The Cl inputs, Cl Inventory Input, Chlorine Control, and Chlorine booster control are all displayed as either Chlorine and Cl or Bromine and Br depending on the chemical selected in the Cl feed menu. This manual is written using the Chlorine setting. If you select Bromine as the sanitizing chemical, the controller will display Bromine and Br instead of Chlorine and Cl, but the menus and functions are otherwise exactly the same as shown.

C – 4.1: pH Setup

After entering the Inputs option, select the pH Setup from the menu. This will allow you to program the following for the pH Input:

Decimal Places (Rep): This option allows you to configure the controller to display pH with 1 or 2 decimal places.

The controller sees far more resolution than what it displays on the screen. Setting the number of decimal places only affects what the user sees and the set points they can enter. It does not affect how accurately the controller controls.

High Alarm (Op): The high alarm will activate when the pH reaches or rises above this setting. You may disable this alarm by holding down the +/- key for 1 second.

Low Alarm (Op): The low alarm will activate when the pH reaches or falls below this setting. You may disable this alarm by holding down the +/- key for 1 second.

Alarm Hysteresis (Mgr): This value sets the amount that the pH reading has to rise above the high alarm or fall below the low alarm before the alarm will shut off.

Input Averaging (Rep): This value sets the number of samples used to get an average for the pH display reading. (The input is read once every two seconds.)

Calibrate (Rep): This selection allows you to perform a two point calibration of the pH Input. Note: You will need a signal generator to perform this function. Hook up the signal generator to the controller and set it to the pH mode. Set the signal generator to a pH setting of 7.0, type that value into the controller, and press enter. Then set the signal generator to a pH setting of 12.24, type that value into the controller, and

press enter. This will give you an accurate reading of the pH level.

Factory Default (Rep): This option allows you to reset the controller back to the factory defaults for all of the pH Input settings.

Disable Input (Rep): Allows you to disable the pH Input on the controller. All control features associated with pH will be disabled and pH will not be shown on the main screen.

C – 4.2: ORP Setup After entering the Inputs option, select the ORP Setup from the menu. This will allow you to program the following for the ORP Input:

High Alarm (Op): The high alarm will activate when the ORP reaches or rises above this setting. You may disable this alarm by holding down the +/- key for 1 second.

Low Alarm (Op): The low alarm will activate when the ORP reaches or falls below this setting. You may disable this alarm by holding down the +/- key for 1 second.

Alarm Hysteresis (Mgr): This value sets the amount that the ORP reading has to rise above the high alarm or fall below the low alarm before the alarm will shut off.

Input Averaging (Rep): This value sets the number of samples used to get an average for the ORP display reading. (The input is read once every two seconds.)

Calibrate (Rep): This selection allows you to perform a two point calibration of the ORP Input. Note: You will need a signal generator to perform this function. Hook up the signal generator to the controller and set it to the ORP mode. Set the signal generator to 0 ORP, type that value into the controller, and press enter. Then set the signal generator to 750 ORP, type that value into the controller, and press enter. This will give you an accurate reading of the ORP level.

Factory Default (Rep): This option allows you to reset the controller back to the factory defaults for all of the ORP Input settings.

Disable Input (Rep): Allows you to disable the ORP Input on the controller. All control features associated with ORP will be disabled and ORP will not be shown on the main screen.



Installation and Technical Manual Rev: G12 C – 4.3: Cl Inputs Setup

C – 4.3.1: Free Cl Setup After entering the Input option, select the Cl Inputs Setup from the menu, then select Free Cl Setup. This will allow you to program the following for the free chlorine sensor input:

Input Source (Rep): Once you have entered the free Cl setup menu, select Input Source. Here you can select whether your free Cl reading will be by calculation, amperometric probe, or disabled. C – 4.3.1.1: Input Source: Calculated High Alarm (Op): The high alarm will

activate when the free Cl reaches or rises above this setting. You may disable this alarm by holding down the +/- key for 1 second.

Low Alarm (Op): The low alarm will activate when the free Cl reaches or falls below this setting. You may disable this alarm by holding down the +/- key for 1 second.

Alarm Hysteresis (Mgr): This value sets the amount that the Cl input readings have to rise above their high alarm or fall below their low alarm before the alarm will shut off.

Factory Default (Rep): This option allows you to reset the controller back to the factory defaults for all the free Cl Input settings.

C – 4.3.1.2: Input Source: Probe Decimal Places (Rep): This option allows

you to configure the controller to display all Cl inputs with 1 or 2 decimal places.

High Alarm (Op): The high alarm will activate when the free Cl reaches or rises above this setting. You may disable this alarm by holding down the +/- key for 1 second.

Low Alarm (Op): The low alarm will activate when the free Cl reaches or falls below this setting. You may disable this alarm by holding down the +/- key for 1 second.

Alarm Hysteresis (Mgr): This value sets the amount that the Cl input readings have to rise above their high alarm or fall below their low alarm before the alarm will shut off. Note this value is used for free, total, and combined Cl alarms.

Input Averaging (Rep): This value sets the number of samples used to get an average for the free Cl display reading. (The input is read once every two seconds.)

Zero point Cal (Rep): This menu informs the installer how to calibrate the input at 0 ppm. This is optional for CCS140 sensors but ECL6 sensors require this calibration when sensor is first installed. To calibrate, shut off flow, fill flow cell with distilled water, let sit for 30 minutes, then enter 0 for the value in this or any single point calibration screen.

Calibrate (Op): This selection allows you to do a single point calibration of free Cl, enter the reading from you test kit, and press enter. The value entered must be 0.5 ppm or greater.

Reset Calibration (Op): Resets the calibration to the original factory setting.

Interlock Duration (Rep): Shown only if the sensor is CCS140. Enter the amount of time to wait after providing power to the probe before allowing free Cl-based control and press enter. (the range is 0:30 to 18:00 hours) When power is first applied to the CCS140 sensor, it takes time for the probe to polarize and give accurate readings. Depending on the probe and the situation, this time can be as little as ten minutes and as long as a half an hour. While the interlock timer is active, all free Cl-based controls are disabled, defaulting to ORP control if available.

Factory Default (Rep): This option allows you to reset the controller back to the factory defaults for all the free Cl Input settings.



Installation and Technical Manual Rev: G12 C – 4.3: Cl Inputs Setup (continued)

C – 4.3.2: Total Cl Setup The Total Cl input is a 4-20mA input that is not assigned to a physical input by default. Before you can even see the Total Cl Setup menu, you must first reassign one of the 4-20mA inputs to the Total Cl function.

Enable input (Rep): Enables or disables the Total Cl input.

High Alarm (Op): The high alarm will activate when the total Cl reaches or rises above this setting. You may disable this alarm by holding down the +/- key for 1 second.

Low Alarm (Op): The low alarm will activate when the total Cl reaches or falls below this setting. You may disable this alarm by holding down the +/- key for 1 second.


Input Averaging (Rep): This value sets the number of samples used to get an average for the total Cl display reading. (The input is read once every two seconds.)

Zero point Cal (Rep): A calibration < 1.5 ppm and second calibration at > 2.5 ppm are required at installation. This menu informs the installer how to calibrate the input at 0 ppm. To calibrate, shut off flow, fill flow cell with distilled water, let sit for 15 minutes, then enter 0 for the value in this or any other single point calibration screen. This calibration can also be done without shutting off flow with water < 1.5 ppm by performing a standard water test kit calibration. You MUST have flow if you’re not using distilled water.

2nd point Cal (Rep): A calibration < 1.5 ppm and second calibration at > 2.5 ppm are required at installation. This menu informs the installer how to complete the initial calibration when using distilled water. Restore flow, wait 15 minutes, then perform test kit singe point calibration entering a value > 2.5 ppm.

C – 4.3.3: Combined Cl The combined Cl option is only shown if both the free and total Cl probes are installed and enabled. The value is calculated from the total and free Cl readings.

High Alarm (Op): The high alarm will activate when the combined Cl reaches or rises above this setting. You may disable this alarm by holding down the +/- key for 1 second.


C – 4.4: Temperature Setup After entering the Input option, choose the Temperature Setup from the menu. This will allow you to program the following for the Temperature Input:

Temp Input Enable (Rep): If a Temperature Sensor is installed, enable this input.

The included temperature probe must be installed in the flow cell and connected to the controller for the temperature display to work.

If enabled, you will have the following options:

High Alarm (Op): The high alarm will activate when the temperature reaches or rises above this setting. You may disable this alarm by holding down the +/- key for 1 second.

Low Alarm (Op): The low alarm will activate when the temperature reaches or falls below this setting. You may disable this alarm by holding down the +/- key for 1 second.

Input Averaging (Rep): This value sets the number of samples used to get an average for the temperature display reading. (The input is read once every two seconds.)

Alarm Hysteresis (Mgr): This value sets the amount that the temperature reading has to rise above the high alarm or fall below the low alarm before the alarm will shut off.

Calibrate (Rep): This selection allows you to perform a two point calibration of the Temperature Input. Note: You will need a signal generator to perform this function. Hook up the signal generator to the controller and set it to the temperature mode (RTD). Set the signal generator to 59 degrees, type that value into the controller, and press enter. Then set the signal generator to 123 degrees, type that value into the controller, and press enter. This will give you an accurate reading of the temperature.

Factory Default (Rep): This option allows you to reset the controller back to the factory defaults for all the Temperature Input settings.



Installation and Technical Manual Rev: G12 C – 4.5: Conductivity/TDS Setup

Note: Available only with Conductivity Input Board.

After entering the Input option, choose the Conductivity Setup from the menu. This will allow you to program the following for the Conductivity Input:

Input Enable (Rep): If a Conductivity/TDS Sensor is installed, enable this input. If enabled, you will have the following options:

Units (Rep): This allows you to choose the units conductivity will be displayed in. You may choose either conductivity (μmhos) or TDS (ppm).

High Alarm (Op): The high alarm will activate when the input reaches or rises above this setting. You may disable this alarm by holding down the +/- key for 1 second.

Low Alarm (Op): The low alarm will activate when the input reaches or falls below this setting. You may disable this alarm by holding down the +/- key for 1 second.

Input Averaging (Rep): This value sets the number of samples used to get an average for the Conductivity/TDS display reading. (The input is read once every two seconds.)

Alarm Hysteresis (Mgr): This value sets the amount that the Conductivity/TDS reading has to rise above the high alarm or fall below the low alarm before the alarm will shut off.

Calibrate (Rep): This selection allows you to perform a two point calibration of the Conductivity/TDS Input.

Factory Default (Rep): This option allows you to reset the controller back to the factory defaults for all the Conductivity/TDS Input settings.

C – 4.6: Flow Rate Setup After entering the Inputs menu, choose the Flow Rate Setup from the menu. This will allow you to program the following for the Flow Rate Input:

Input Range (Rep): Allows you to change ranges between gpm and kgpm or lpm and klpm.

Max Flow Rate (Rep): Set this value to the pump’s maximum flow rate. This is mainly used to help scale VFD control, but may be used in future for other features.

Display Volume (Rep): Selects whether or not to display the filter volume on the normal display.

K Factor (Rep): (See Section I for values) The K Factor is the number of pulses the sensor will generate for each engineering unit of water that passes by it. The K Factor is determined by the size and material of the pipe as well as the fittings that are used.

No Chemical Feeds on Low Flow Alarm (Rep): Chooses whether or not to lockout chemical feeding on a low flow alarm.

Low Alarm (Op): The low alarm will activate when the flow rate reaches or falls below this setting. You may disable this alarm by holding down the +/- key for 1 second.

Alarm Hysteresis (Mgr): This value sets the reading that the flow rate must rise above the low alarm before the alarm will shut off.

Input Averaging (Rep): This value sets the number of samples used to get an average for the flow rate display reading.

The controller updates the flow rate every two seconds by taking the total number of pulses recorded over the last ten seconds, multiplying that by six (to get sixty seconds or 1 minute), then divides by the K factor to get gpm or lpm. The ten second timeframe is an average by itself, so you should only set the Input Averaging to greater than one if the flow rate reading bounces up and down.

Factory Defaults (Rep): This option allows you to reset the controller back to the factory defaults for all of the Flow Rate Input settings.



Installation and Technical Manual Rev: G12 C – 4.7: pH & Chlorine Inventory Setups

After entering the Inputs menu, choose pH Inv or Cl Inv from the menu. This will allow you to program the following for the selected inventory input.

Sensor Type (Rep): 4-20 mA

Input: Select this if you are using a BECSysLS or similar 4-20mA device. The controller will prompt you to choose between level or weight, and then ask you for the input range of the sensor. The input range is whatever the maximum value the sensor is rated to measure and ideally the value represented by 20mA.

N.O. dry contact:

Select this if you are using a float with normally open contact switches closing when the chemical level falls below the point you wish an alarm to be triggered.

N.C. dry contact:

Select this if you are using a float with normally closed contact switches opening when the chemical level falls below the point you wish an alarm to be triggered.

Not Installed: No sensor installed.

C – 4.7.1: Sensor Type 4-20mA Input Be sure to set the dipswitch to the 4-20mA position.

Sensor Type (Rep): Allows you to change the sensor type to a different type.

Level or Weight (Rep): Choose if your inventory is to be measured by the level of chemical or the weight of the chemical.

Input Range (Rep): This value sets the input range which is whatever the maximum value the sensor is rated to measure and ideally the value represented by 20mA.

Low Alarm (Op): This value sets at what level or weight the inventory low alarm will be activated. You may disable this alarm by holding down the +/- key for 1 second.

Alarm Hysteresis (Mgr): This value sets at what level the inventory level or weight has to rise above the low level or weight alarm setting before the alarm will shut off.

Input Averaging (Rep): This value sets the number of samples used to get an average for the inventory level.

Calibrate (Rep): Once you have entered Inventory Setup, select Calibrate from the menu.

This calibration is only needed if the readings are accurate at one level/weight, but are off by an increasing amount the farther away you go from that level/weight. If the reading is off by a consistent amount throughout the input range, perform a single point calibration by pressing the Cal button and selecting this input from the list. It is important that the Input Range is set to the correct value; otherwise you may find that the controller refuses to accept the second value due to it being "out of range" or "points too close" (see below).

Calibration is a two step process:

1) While the inventory is low, measure or estimate the current level/weight, enter this value in as the first point and press enter. The controller will not time out and exit the menu while waiting for the second point of a calibration, so you do not need to lock the screen here.

2) Fill the inventory by a known amount. Add this amount to the value you entered for the first point, enter the sum as the second point.

If you get a "points too close" error message, either the values you entered or the input readings taken for those values were too close together to perform an accurate calibration calculation. You either did not add enough inventory, the Input Range is wrong for the sensor attached, or there could be a problem with the wiring if the reading did not change when you added the inventory. If you get a "out of range" error message, you entered a value outside of the configured Input Range. If the sensor is supposed to be able to measure the value you entered, then the Input Range was not set to the correct value and should be corrected. If you discover later that your first point was off, simply do a single point calibration to correct it.

Factory Defaults (Rep): This option allows you to reset the controller back to the factory defaults for all of the inventory input settings.

C – 4.7.2: Sensor Type dry contact (NO or NC) Be sure to set the dipswitch to the digital position.

C – 5: Control Outputs C – 5.1: Assign Relays

(Rep) To enable control functions, you must assign that function a relay. Control functions are broken up into two groups; Sanitization Feeds and Other Feeds. To set or change the relay used or to disable a control, press the Menu button, then select Control Outputs, Assign Relays, select the group the control function is listed under (see below), and then the control function itself. This will display all of the relays available to be assigned to this control, including the current relay if one was already assigned. Select the relay you wish to assign to the control function or select Disable function to disable the function and free up the currently assigned relay. For information on configuring a particular control, see that control's section in this manual. The following lists the different control functions under each category and a brief description:

C – 5.1.1 - Sanitization feeds Cl Feed - This is your primary Cl feed. Cl Booster - The Cl Booster is a highly

programmable secondary Cl feed for helping maintain the ORP and/or free Cl levels of the pool during high bather loads. This feed also runs during Super Chlorination cycles, and is locked out by the Cl (Br) failsafe alarm.

SuperChlor - The Super Chlorination (shock) function is unique to the other control functions in the sense that you can either assign its own relay [for controlling an additional chlorine feed or a non-chlorine shock chemical feed], or assign it to the primary Cl feed's relay if an additional feeder is not used. SuperChlor will always override and run the primary Cl feed and the Cl booster feed, if enabled, in order to help bring the ORP or free Cl level up to the superChlor set point.

DeChlor - The DeChlor feature is only shown if SuperChlor has been assigned a relay. DeChlor is intended to be used following a super chlorination to bring the ORP and/or free Cl level back down to a safe level.

Ozone - The Ozone feed is a highly programmable feed similar to the Cl booster, but is not limited by the Cl failsafe or forced to operate during a Super Chlorination cycle.

UV Turndown – this control activates a relay to turn down a UV unit prior to recirculation shutdown and filter backwash and optionally control to a combined chlorine set point.

C – 5.1.2 - Other Feeds pH feeds - Two pH feeds are available for use.

If both feed directions are used, they will work together to maintain a single set point. To switch the pH feed direction, you must set the current pH function's relay to disabled and assign that relay to the other pH function.

Heater - The heater control allows you to control the heater to a different set point at different times of the day, automatically shut down during no flow or low flow alarms, interlock with the recirculation pump and backwash (fireman switch).

Polymer Feed - The polymer feed uses the turbidity input or a cycle timer to determine when to add polymer to the water to increase the filtration power of your filters.

Autofill - The Autofill control operates a makeup water valve to add water to your pool. It uses either or one or two proximity switches or the Surge Pit 4-20mA Input with programmable alternate set point to control to a different level while, for example, feature pumps are running.

TDS Control - The TDS control works with the Autofill control or an independent Autofill device to lower the TDS of the pool by operating a drain valve to drain water while the Autofill adds fresh water - requires the conductivity/TDS sensor.

Sensor Wash - Sensor Wash is a rename-able programmable cycle timer with four separate schedules that is usually used to trigger an acid feed wash to clean the pH and ORP probes.

Enzyme Feed – this is rename-able programmable daily cycle timer.

Recirculation Pump - The recirculation pump control is used to shutdown the recirculation pump under certain alarm conditions and by the powersaver control option.

Alarm Relay - The Alarm Relay triggers whenever there is an active alarm or while the emergency off feature is active.



Installation and Technical Manual Rev: G12 C – 5.2: pH Control

By default, the pH feed down control is assigned to relay 1. To switch to pH feed up control, disable the pH feed down by unassigning its relay and then assign the relay to the pH feed down control. See Section 5.1. To enable dual pH control (feed up and feed down), assign a relay to both pH feed up and pH feed down controls. After entering the Control Outputs option, select pH Control from the menu. This will allow for the programming of the following for the pH control:

Control Type (Op): Choose from On/Off or Time Base Proportional control.

In general, if you are using a motor driven chemical feeder then you should choose the On/Off option. If you are using a solenoid driven or pulsed diaphragm chemical feeder (such as Pulsatron, most LMI models or most Prominent Models), you should choose the TBP option. This feature helps to hold a set point and to minimize over-shoot by making a standard feeder mimic the action of more sophisticated modulating feeders. If you choose the On/Off option and are feeding up, then the controller will activate the chemical feeder whenever the pH falls below the set point and continue to feed until the pH rises above the set point plus hysteresis at which point it will stop. If you choose the TBP option and are feeding up then the controller will activate the chemical feeder whenever the pH falls below the set point and will feed for a percentage of the Time Base (default one minute) proportional to the offset from set point. For the remainder of the Time Base the feeder will be paused. The feeder will continue this feed and pause cycle until the controller achieves the set point plus hysteresis. The closer to set point, the less time the feeder is ON.

Set Point (Op): This value sets the desired level to maintain the pH at. Input the desired pH set point.

Span/Prop. Bnd (Op): This option is only shown if the Control Type is Time Base Proportional. This value sets the distance (or span) from the set point that the output will be proportionally controlled.

Time Base (Op): This option is only shown if the Control Type is Time Base Proportional. This sets the total time that control is based on. During this time, the feeder will turn on for a percentage of the Time Base and turn off for the remainder.

Minimum On Time (Rep): This value is the minimum time the pump will be on during Time Base Proportional control. This helps protect the feeder from cycling on or off for too short a period of time.

Failsafe Timer (Op): This value sets the time that the relay is allowed to stay continuously on.

The most common failures of automated chemical feed systems are depletion of the chemical supply and/or chemical feeder failure. Both problems result in the controller being unable to reach set point in a reasonable period of time. The failsafe timer sets the maximum length of time the feeder can run. If the feeder has been trying to achieve set point without success for the selected time, the controller will cut power to the feeder, flash the Reset Fail/Safe LED on the face panel and display a message to alert the operator. If in TBP Pause mode, the controller will reset the timer. An operator must reset the failsafe through the Reset Fail/Safe button to re-enable normal control.

Hysteresis (Rep): This value sets the amount the input must rise above (feed up) or fall below (feed down) the set point before the feed is shut off. (the range is from 0.0 to 1.4)

Dead Band (Mgr): This option is only shown under dual pH control. This value sets the amount the input must exceed the set point by before the feed of the opposite direction will trigger. (The range is from twice the feeds' hysteresis to 2.8 pH)

Warning: Disabling the failsafe timers is highly discouraged. They are an important safety feature to protect against dangerous

chemical overfeeds and will protect the equipment from running continuously if it runs

out of chemical.

Warning: Increasing or decreasing the Span/Prop. band or Time Base may cause the feed to severely overshoot or never achieve set point.

Adjust this option only when recommended to do so by a factory representative.



Installation and Technical Manual Rev: G12 C – 5.3: Chlorine Control

After entering the Control Outputs option, select the Cl Control from the menu. This will allow the programming of the following:

Sanitizer Chemical (Op): Sets the sanitizer chemical name (Chlorine or Bromine).

This option controls what chemical name the controller displays for the Cl inputs and the primary sanitization/oxidizing chemical.

Control Input Src (Op): This option is only available if the free Cl Input source is set to Calculated or Probe. Choose between ORP and free Cl to use as the primary control input for the sanitizer feed.

If the free Cl Input is selected and the free Cl Input source is set to probe, ORP is still used for control while the free Cl interlock timer is running. If the free Cl Input is selected and the free Cl Input source is set to calculated, the controller still controls off of ORP, but the ORP set point is calculated by the controller based on the free Cl set point, the pH set point, and the free Cl calibration. Modification of any one of those three values will result in a new ORP set point.

Control Type (Op): Choose from On/Off or Time Base Proportional control.

In general, if you are using a motor driven chemical feeder then you should choose the On/Off option. If you are using a solenoid driven or pulsed diaphragm chemical feeder (such as Pulsatron, most LMI models or most Prominent Models), you should choose the TBP option. This feature helps to hold a set point and to minimize over-shoot by making a standard feeder mimic the action of more sophisticated modulating feeders. If you choose the On/Off option, then the controller will activate the chemical feeder whenever the ORP falls below the set point and continue to feed until the ORP rises above the set point plus hysteresis at which point it will stop. If you choose the TBP option, then the controller will activate the chemical feeder whenever the ORP falls below the set point and will feed for a percentage of the Time Base (default one minute) proportional to the offset from set point. For the remainder of the Time Base the feeder will be paused. The feeder will continue this feed and pause cycle until the controller achieves the set point plus hysteresis. The closer to set point, the less time the feeder is ON.

ORP Set Point (Op): This option is NOT shown if the Control Source is set to free Cl and the free Cl Input source is set to Calculated. This value sets the desired level to maintain the ORP at.

ORP Span/Prop. Bnd (Op): This option is only shown if the Control Type is Time Base Proportional and the ORP Set Point is shown above. This value sets the distance (or span) from the set point that the output will be proportionally controlled.

Free Cl Span/Prop Bnd (Op): This option is only shown if the Control Type is Time Base Proportional, the Control Source is set to free Cl, and the free Cl Input source is set to probe. This value sets the distance (or span) from the set point that the output will be proportionally controlled.

Free Cl Set Point (Op): This option is only shown if the Control Source is set to free Cl. This value sets the desired level to maintain the free Cl at.

Free Cl Ctrl Hyst (Rep): This option is only shown if the Control Source is set to free Cl and the free Cl Input source is set to probe. This value sets the amount the input must rise above set point before the feed will shut off.

Time Base (Op): This option is only shown if the Control Type is Time Base Proportional. This sets the total time that control is based on. During this time, the feeder will turn on for a percentage of the Time Base and turn off for the remainder.

Minimum On Time (Rep): This option is only shown if the Control Type is Time Base Proportional. This value is the minimum time the pump will be on during Time Proportional control. This helps protect the feeder from cycling on or off for too short a period of time.

Warning: Increasing or decreasing the time base may cause the feed to severely overshoot or never achieve set point. Adjust this option only when recommended to do so by a factory

representative.

Warning: Increasing or decreasing the proportional band may cause the feed to

for VFD control. The options are Flow Rate and Disabled. When disabled, only % out set points are used.

Turndowns (Rep): Allows you to configure scheduled and manual turndowns. • Scheduled turndowns will override the

regular set point at their scheduled times. • If two scheduled turndowns overlap,

turndown 1 has the highest priority, turndown 2 has the second highest priority, and so on. Once the highest priority turndown’s scheduled time ends, the next highest active turndown’s set point will be used until its time ends or a higher turndown becomes active.

• Manual turndowns are configured here but are triggered from the main menu.

• Manual turndowns override the normal and scheduled set points.

Auto Tune (Rep): This option is only shown if the Control Input is set to Flow Rate. Auto tune must be triggered before the controller will operate the VFD based off of flow rate. Selecting this

option will step the user through setting and/or verifying the max flow rate and the targeted flow rate (set point) before triggering the automatic tuning sequence. Auto tune first sets the VFD output to a level below the targeted flow rate and waits for the flow rate to stabilize. Once stable, it ramps the output above the targeted flow rate and measures how quickly it reaches its final level and other timing parameters. Once auto tune finishes, it begins controlling the VFD to targeted flow rate set point.

Dead Time (Rep: Change/Op: View Only): This option is only shown if the Control Input is set to Flow Rate. This option is set by auto tune and should not be changed unless requested by BECS Technology. This value represents the time delay between a change in the pump’s speed and when the flow rate meter sees the change.

Prop. Band (Rep: Change / Op: View Only): This option is only shown if the Control Input is set to Flow Rate. This option is set by auto tune and should not be changed unless requested by BECS Technology. This value represents the proportional range from the current flow rate set point and sets the scale of much to change the VFD output to reach the set point. The greater the band, the less the controller will change the output.

OOR alarm delay (Op): This option is only shown if the Control Input is set to Flow Rate. If the output required to meet the set point exceeds 100%, the triggering of the Out Of Range (OOR) alarm will be delayed by this amount of time. Set to 0 to disable the alarm.

Set Point (Op): Allows you to set the value to control to. (in % or flow rate depending on what the control input is set to).

Dead Band (Rep: Change / Op: View Only): This option is only shown if the Control Input is set to Flow Rate. The VFD output will not change until the input is this far away from the set point. Increase this on systems where the flow rate reading is so unstable that the controller constantly oscillates the VFD’s speed in trying to reach the set point.

Ramp up rate (Rep): Ramp up rate should always be set on the VFD itself and never set to anything but 100% on the BECSys controller unless requested by BECS Technology. Sets the rate which the output will ramp up in % per second. Setting the value to 100% disables ramping up.



Installation and Technical Manual Rev: G12 Ramp down rate (Rep): Ramp down rate

should always be set on the VFD itself and never set to anything but 100% on the BECSys controller unless requested by BECS Technology. Sets the rate which the output will ramp up in % per second. Setting the value to 100% disables ramping down.

Backwash Output (Rep: Change / Op: View Only): This option is only shown if linked with a BECSysBW and the backwash control is configured. Sets the VFD percent output to use when backwashing.

Minimum Output (Rep: Change / Op: View Only): Allows you to set the minimum percent output allowed. The controller will always keep the VFD output above this % except when the relay is off.

Kp (Rep): This option is only shown if the Control Input is set to Flow Rate. This option should not be changed unless requested by BECS Technology.

Ki (Rep): This option is only shown if the Control Input is set to Flow Rate. This option should not be changed unless requested by BECS Technology.

Delay Duration (Op): This option is only available if flow restored feed delay is enabled. Enter the desired time that the chemical feeders must wait to operate after flow is restored.

C – 6.2: Power Saver Power Saver is a timer triggered function that saves energy by shutting down the recirculation pump for programmable periods of time while the pool is not in use. When active, power saver has the following states: • CONTROLLING: At least one control

function is currently feeding. Once all feeds have finished, the system will enter the GOING TO SLEEP state.

• GOING TO SLEEP: All control functions must be satisfied (they don't turn their feeds on) for the Enter Sleep Delay duration before allowing system to enter the SLEEPING state.

• SLEEPING: Timed period (Sleep Duration) where the shutdown of recirculation pump is triggered and all feeds are disabled. After entering SLEEPING state, the recirculation pump will continue to run until the heater and ozone fireman switch timers run out. The sleep timer starts when all conditions have been met, not when controller shuts down the recirculation pump. Only a timer triggered backwash, the sleep timer expiring, or the Power Saver timer expiring will put the system into the WAKING UP state. No feeds or input alarms will operate while the system is asleep or waking up.

• WAKING UP: Timed period (Exit Sleep Delay) where the recirculation pump is ran before allowing feeds to operate. Once the wake up time expires, if the Power Saver timer expired, the system will remain awake even if all feeds are satisfied. Otherwise the system enters the CONTROLLING state, performing a backwash if triggered, and will reenter GOING TO SLEEP again once all feeds have been satisfied again.

While Power Saver is active, the system automatically uses the Alternate Temperature

set point for the Heater and the Alternate ORP and/or Alternate ppm set points for the Cl feed.

Enable (Op): Enable or disable the Power Saver feature.

4 Event 28 Day Timer (Op): The 4 Event 28 Day Timer allows you to program power saver's schedule. See the section on the Chlorine (Bromine) Control's Alt Set Point for details on how to set this.

Sleep Duration (Op): Sets how long the controller will sleep.

Enter Sleep Delay (Op): Sets how long to wait after all of the feeds have been satisfied before entering SLEEP (i.e. the GOING TO SLEEP duration). If any feed starts feeding during this time, the controller goes back to the CONTROLLING state.

Exit Sleep Delay (Op): Sets how long to wait after coming out of sleep before allowing any feeds to run. (i.e. the WAKING UP duration).

Alternate ORP (Op): Sets the alternate ORP value used during power saver and the Cl feed's alternate set point event timer.

Alternate free Cl (Op): Sets the alternate free Cl value used during power saver and the Cl feed's alternate set point event timer.

Alternate temp (Op): Sets the alternate temperature value used during power saver and the heater's alternate set point event timer.

C – 6.3: pH Lockout

C – 10: 4-20mA Outs The 4-20mA output board allows you to connect to either a building management system or to control a VFD. If you have a 4-20 mA board installed in your system you may choose 4-20mA outputs from the main menu. By selecting one of the 4-20mA output channels you will be able to select the following: Usage (Mgr): Selects what to use the selected 4-

20mA output channel for. • Recorder Out: Output a 4-20mA signal based

on one of the controller’s inputs, feed set points, or alarm set points. Once you have selected Recorder Out, you will need to then select the Source (see below).

• VFD Control Out: Use this channel to control a VFD unit connected to the recirculation pump.

• Disable: Disables the 4-20mA output. Source (Mgr): Only shown if the usage is set to Recorder

Out. Configures the recorder out's signal source. This is broken up into four different categories to make selection of the source easier. Select the Recorder Out's source from one of the following lists: Inputs: Lists all enabled inputs compatible for

outputting on the selected 4-20mA output channel.

Feed Set Points: Lists all enabled controls using feed set points. Note that some feeds have more than one set point to control to. If a control's feed point is selected, the output signal will be whatever value that feed is controlling to.

High Alarm Set Points: Lists all available high alarm set points for use as the source.

Low Alarm Setpoints: Lists all available low alarm set points for use as the source.

Disable: Disables the recorder out. 20 ma value (Mgr): Only shown if usage is set to

Recorder Out. Enter the value which the recorder will output 20 mA for.

4 ma value (Mgr): Only shown if usage is set to Recorder Out. Enter the value which the recorder will output 4 mA for.

Example: Source: ORP input, 4 mA value = 600 mV, 20 mA value = 900 mV. ORP values between 600 and 900 mV are lineally scaled between 4 and 20 mA as shown below.

C – 11: Access Menu

Once the Rep and Operator access codes have been set, the controller will require users to enter their access code before allowing them to enter the menus or set any values under the quick set keys. The controller automatically displays the access screen whenever a user does not have a high enough access level to enter a specific screen.

To enter an Operator access code, press 1. To enter a Manager access code, press 2. To enter the Rep access code, press 9. If at anytime you wish to logon as another access level, you may do so by pressing the Menu key and selecting Logon from the main menu.

Section D: The Normal Display The normal display refers to the screens that display all of your inputs, current alarms, and status messages. These are read only and do not offer any selections to chose from. D – 1: Inputs and Feeds

When no alarms or status messages are present, the entire screen will be used to display all of the enabled inputs. If a particular input is used by a control output and the control output is feeding based off of that input, the controller will display a message next to that input indicating so. Other information such as LSI/RSI calculated values and Customer/Location/Rep information may also be displayed. If there are more items to show than there is room for, the controller the controller will page through them until they all have been displayed, then start over.

Pressing the right arrow key (Next) will display the next page. Pressing the Lock Screen button will prevent the controller from paging the screen to show more inputs, alarms, and other status information. You can adjust the rate at which the controller pages by pressing the up and/or down arrow keys.

D – 2: Alarms & Status messages

When one or more alarms are active, the bottom three lines are used to list them. If more than three alarms are active, the controller will page through them three at a time until they all have been displayed, then start over. Super chlorination, dechlorination, sensor wash, backwash, and power saver all display status information in this area as well. If there are any

active alarms while one or more of these control functions' are active, the alarms will be shown every other page while the control functions will alternate with each other.




Section E: Using the Face Panel Quick Keys

E – 1: The Set Points Key The Set Points Key on the front face panel, when pressed, allows you to quickly change desired feed set points for the various control outputs that are enabled.

To change the existing feed set point, first select the desired option, input the new value, and then press enter. Pressing the Set Points key a second time will display the alarm set points for all of the enabled inputs.

To change the existing alarm set point, first select the desired option, input the new value, and then press enter.

E – 2: The Relay Mode Key

Pressing the Relay Mode key on the front face panel shows you which options have been assigned relays, and each of the relays' current mode (AUTO/MANUAL OFF/MANUAL ON) and its state (Off or On). Pressing the Relay Mode key again will cycle through the Relay Modules connected to the controller, showing what is assigned to those relays and their current state.

By selecting one of the assigned relays, you are allowed to choose between automatic, manual on or manual off. Unused relays and the alarm relay cannot be manually overridden, but their current state is always displayed. If Manual On is selected, you will be prompted to enter how long the relay can stay in Manual On before returning to Auto (the maximum on time is 30 minutes).

To test a relay or to prime a pump (on the local relay screen), lock the screen while in the main Relay Mode menu, then press the relay's numeric key (i.e., for relay 3, press the 3 key). This will turn the relay on for as long as you are pressing that key. If the relay is already on, this will have no affect. The Relay Expansion modules have a button to test the relays.

If you have the controller set up to control a VFD, pressing the Relay Mode Key again will display the 4-20mA Control Outputs.

From here you can switch between auto and manual on. There are two different manual on options: Manual % Out and Manual Flow Rate. Manual % Out sets the VFD output at a specified

value. Manual Flow Rate changes the VFD output to maintain a specified flow rate.




E – 3: The Cal Key (calibration) Pressing the Cal (calibration) key on the front face panel will list the inputs you can perform a single point calibration on. Select the input you wish to calibrate and enter the proper value.

ORP can only be calibrated by Rep if the rep access code is set. Perform a single point calibration if the reading is off by a consistent amount throughout the input range. If the readings are accurate at one reading, but are off by an increasing amount the farther away you go from that reading, check the wiring and the condition of the probe (if applicable). If the problem is not found, you may need to do a two-point calibration located in the input's menu under the Menu button.

E – 4: The Reset Fail / Safe Key

The Reset Fail / Safe key on the front face panel, when pressed, provides the following information and options: Lists any active failsafe alarms and provides the

option to reset them. A failsafe alarm is generally triggered when one of the relays has remained on past the set time the function has been given to reach its set point. By choosing to reset the failsafe, the control that triggered the failsafe will be able to resume operating normally once again.

Displays the remaining time a relay may remain on before a failsafe will occur for each active feed with a failsafe time set.

Provides the option to abort the Flow Restored Feed Delay whenever the flow restored feed delay is enabled and is currently delaying feeds.

E – 5: The Emergency Off Key When the Emergency Off button is pressed, all relays are automatically shut off except for the alarm relay which will turn on. All the other relays will remain off until the emergency off button is press again.

Warning: Before resetting any failsafe alarms, ensure that all functions of the

controller are working properly.




Section F: Startup Programming

• This section covers programming the controller to enable specific features that people frequently need help doing so.

• All startup programming procedures require the user to be logged as Rep and do not include the step of logging on if the Rep access code has been set. If the Rep access code has not been set, the user is automatically logged on as Rep when they press any menu button.

F – 1: VFD Control

• The BECSys controller can control one or multiple VFD units based on the flow rate input. • To enable VFD control, you must assign one relay to the recirculation pump control and a 4-20mA output

channel. • The relay is wired to the VFD’s start/stop terminals. On most VFDs this signal is DC. You must use a

mechanical relay wired as a dry contact for DC signals. If no dry contact mechanical relays are available in the controller, you will need to instead use an external mechanical relay driven by any of the controller’s relays.

• When controlling more than one VFD, each VFD requires a separate relay and a separate 4-20mA output channel. Normally a single relay in the controller is used to activate all of the external relays wired to the VFDs’ start/stop inputs.

F – 2: Autofill • Autofill can be controlled using the Surge Pit 4-20mA level input or single point sensors like proximity sensors,

floats or the BECSys Solid State Autofill sensors. • When using single point sensors, you have the option to use one sensor to control both the start and stop fill,

or two sensors, one that senses the high (stop) level and another to sense the low (start) level. F – 2.1: 4-20mA level sensor (Surge Pit)

Section G: Troubleshooting

G – 1: Calibration Errors If during calibration of the inputs you receive an error message, check the following: G – 2.1: Specific Errors 1) "Points too close together or invalid." – Either

the values you entered or the input readings taken for those values were too close together to perform an accurate calibration calculation. Try calibrating again with a greater difference between the two points.

2) “Value too low. Check probe and flow.” – Indicated on free Cl calibrations if the user attempts to calibrate below 1.0 ppm for CCS140 sensors or 0.5 ppm for ECL6 sensors. Increase the chlorine in the pool above the values listed.

3) “Sensor error. Reading out of range.” – This message indicates the sensor would have been calibrated too far away from the controller’s safety limits. For ORP and pH sensors, this may indicate it is time to change the probes.

G – 2.2: General tips 1) Try calibrating again, allowing more time

between the 1st and 2nd point calibration. 2) If you are using a BECSys HRC-1 make sure the

Hi-Z switch is in the off position. 3) Double check to make sure you have the proper

wires connected to the input.

G – 2: Low Battery Alarm

The Low Battery Alarm is displayed when the controller detects the battery voltage is too low. If your controller is displaying a Low Battery Alarm, first double check the battery switch. Dip switch 8 on the CPU board is for the battery, it should be in the “On” position. If this switch is in the “On” position and the alarm is still displayed, you may have a dead battery.

G – 3: Chlorine Sensors G – 3.1: General Tips 1) Bouncing Readings – Verify that both flow and

pressure are constant. 2) No Flow Through Flow Cell – Verify the

position of the Total Chlorine Sensor. If the sensor is installed too far into the flow cell, it will restrict flow.

G – 3.2: Free Chlorine 1) Incorrect Reading – Try resetting the calibration.

(See Section C – 4.3.1.2). 2) Calibration Error – The calibration value must

be above 0.5 ppm.

G – 3.3: Total Chlorine 1) No Reading – If there is no electrolyte in the

Total Chlorine Sensor, the sensor will read 0. 2) No Reading – Possibly one of the fuses on the

Loop Power Supply Board has blown. Power down the controller and check the fuses using a multi-meter.




Section H: Maintenance The BECSys controller requires no maintenance other than a periodic calibration check and sensor cleaning. H – 1: Potentiometric Sensors (pH and ORP)

H – 1.1: Electrode Cleaning Slow response time and large offsets may indicate the electrode has become coated. The nature of the coating will dictate the type of cleaning technique that should be used. Soft coatings, like bacterial films, are best removed

using a squirt bottle or the water jet from a faucet. If this is not successful, then gently wipe with a soft wet cloth.

For a more severe coating, first try a strong detergent (something similar to Dawn liquid detergent) and warm water, using a soft brush (like a toothbrush). Isopropyl alcohol on a Q-tip is another good choice. Rinse the measuring end in distilled water before reinstallation.

Greasy and oily coatings are best removed with a detergent solution or a solvent that will not attack the sensor body. Methanol and isopropyl alcohol are good choices for solvents. Acetone, MEK, THF, or trichloroethane will irreparably harm the electrode.

Hard coatings, like calcium or lime scale, are best removed with a solvent appropriate for the particular coating. A 5% solution of hydrochloric acid (HCl) would be a good choice for calcium scale. If unsure of the proper solvent to remove a hard mineral coating, then alternate between a 5% hydrochloric acid and a 4% sodium hydroxide (NaOH) for 10 minutes each. After treating the electrode with these strong acids or bases, rinse the electrode with water and soak it in a pH 4 buffer for at least 1/2 hour.

The platinum tip of an ORP sensor can be cleaned with an abrasive as a last resort. Gently scour the platinum with a 600 grit wet emery cloth, or preferably, a 1-3 micron alumina polishing powder.

H – 1.2: Long-Term Storage

Save the wetting cap that came with the sensor for long-term storage. After removing the sensor from the flow cell, clean it as in routine maintenance, then store it in the wetting cap using

a pH 4 buffer saturated with potassium chloride (KCl). The potassium chloride will prevent electrolyte from leaching out of the sensors reference cell. The wetting cap only needs to be half full. If a number of sites are going to be serviced, for example, at the end of a season, then it might be a good idea to carry a pint of 4.0/KCl storage solution.

H – 2: Free Chlorine Sensor

Check the sensor measurement at regular intervals (at least once a month), and perform a recalibration if necessary. As a rule of thumb, refill the measuring cell with electrolyte once per season (or every 12 months). H – 2.1: Cleaning If the sensor membrane is visibly soiled, then

remove the sensor from the flow cell and clean the membrane with a gentle water jet, or soak the membrane for a few minutes in a 1% to 10% hydrochloric acid (HCl) solution. Avoid chemical additives as they may damage the membrane.

Replace a heavily soiled or damaged membrane. H – 2.2: Long-Term Storage

Save the yellow protective cap that came with the sensor for long-term storage. After removing the sensor from the flow cell, empty the measuring cell of electrolyte (particularly if dehydration of the membrane is possible). Rinse the measuring chamber and electrode shaft with cold water and let them dry. Then screw the measuring cell down loosely and not to the stop, so that the membrane remains unstressed. When the sensor is put back into service, it will have to be refilled with electrolyte and run through an initial polarization before calibration.

H – 2.3: Filling electrolyte Unscrew the measuring chamber from the shaft. Hold the measuring chamber at an angle and fill in

approximately 7 to 8 ml electrolyte, up to approximately 1 cm under the top edge.

Tap the filled chamber several times on a flat surface to release any air bubbles.

Screw the electrode shaft into the measuring chamber vertically from above, displacing all air from inside. Tighten slowly to the stop.

Warning: You may lightly blot the water on a pH sensor tip on a paper towel, but never

vigorously rub or wipe the pH bulb because this may scratch the delicate outer layer on the pH

glass impairing its response.




H – 3: Total Chlorine Sensor Check the sensor measurement at regular intervals (at least once a month), and perform a recalibration if necessary. As a rule of thumb, refill the measuring cell with electrolyte every 3 to 6 months. The membrane should be replaced once a year. H – 3.1: Long Term Storage

After removing the sensor from the flow cell, empty the measuring cell of electrolyte (particularly if dehydration of the membrane is possible). Rinse the measuring chamber and electrode shaft with cold water and let them dry. Then loosely screw the measuring cell down. The membrane must not rest against the measuring electrode. When the sensor is put back into service, the electrode tip must be cleaned with the special abrasive paper and a new membrane cap must be used.

H – 3.2: Cleaning The Electrode Tip To clean the electrode tip, first remove the membrane cap. Be sure to expose the vent when removing the membrane cap to prevent damage to the membrane. Clean the electrode finger using a clean, dry paper towel. The special abrasive paper is used on just the electrode tip. Place the special abrasive paper on a paper towel and hold it at one corner. Hold the probe perpendicular to the paper towel and abrasive paper and rub the electrode tip two or three times across the abrasive paper. Once the tip has been cleaned, replace the electrolyte.

H – 3.3: Filling Electrolyte See Section A – 6.3.

H – 4: Conductivity Sensor H – 4.1: Cleaning The sensor should be kept as clean as possible for

optimum measurement accuracy. The frequency of cleaning will depend upon the application.

When necessary, wash with strong detergent (something similar to Dawn liquid detergent) and warm water, using a pipe cleaner or small soft brush for most fouling. Rinse with tap water to completely remove the detergent, and then perform a final rinse with distilled or de-ionized water.

For hard scale, try a mild acid solution. Vinegar will often do it, 5% hydrochloric acid if the vinegar doesn’t work. You can use acetone or something similar on this sensor.

Warning: Do not soak the sensor in a strong solvent as the O-rings may be attacked after

time.

Warning: Residue from cleaning solutions, or even skin contact, can leave trace elements on

the sensor that may affect the reading,

Warning: Never touch the electrode finger.
