ORP/pH Digital Controller

Rola-Chem Generation II

Digital ControllersReady-to-Mount Systems

1



What is ORP?

• ORP stands for Oxidation Reduction Potential.

• ORP is a measurement to oxidize

contaminants. It is the only practical method

we have to electronically monitor sanitizer

effectiveness.

• ORP and pH sensors allow us to electronically

monitor and control sanitizer residual and pH

automatically.

2



What Affects ORP?

• Pool chemistry:

– Cyanuric acid levels

– pH variations

– Temperature changes

– Total dissolved solids

– Chlorine neutralizer

– Bather loads

– Use of alternative sanitizer

3



Why Use Automation?

• Help ensure bather safety

• Protect pool equipment from damage

•

Minimize costs associated with chemicals,equipment and liability

• Flatten curve of dispensing chemical (manual

feed vs. automated feed)• Reduce need for human contact with chemical

4



Benefits of ORP/pH Controllers

• Continually monitors PH and sanitizer activity

• Constantly adjusts feeding of chemicals

proportional to demand

• Eliminates human error

• Maintains chemical levels 24 hours a day

•

Complies with health departmentchemistry standards

5



Optimize Chemical Usage

• Dispenses chemical only as required, thus

creating significant cost savings

•

Equalizes water chemistry, eliminating PH andsanitizer highs and lows

Ready-to-Mount System Components

• ORP/pH Controller / pH Controller – Flow Cell

– Flow Switch

– ORP Probe – pH Probe

– Flow Cell Valves

– Rola-Chem Chemical Feeders

– All tubing, inlet/injection fittings – All mounted on polypropylene board

17



Quick Start Reference

• Quick Start Reference

– On/Off:

• Press the mode button to turn on

• Note: blue ‘FLOW’ light must illuminate

• Press and hold the mode button to turn off

• “OFF” will be displayed in the window

18



Operation

• To Operate:

– Press and release the mode button until the

“AUTO” LED is lit. Unit will now operate in the

factory preset settings.• Set levels: ORP = 650 mv, pH = 7.4

• Feed times: 0.6 second feed with a 5-minute delay

• Limits: ORP; 900 hi, 100 low, pH = 8.0 hi, 7.0 low

19



Changing Settings

• To change settings: – Note: Press and release the mode button until the desired

ORP or pH LED is lit. Once the settings are changed, theywill remain at those settings until they are changed again.

– Set level: Press the Set Level button until the desired setpoint is reached. Release the button.

– Feed time: Press the Feed Time button until the desiredfeed time is reached. Release the button. The numbers

represent the seconds of feed time (all with 5-minutedelays). Range is 0.6 to 900 seconds (15 minutes). Constantfeed is ‘con.’ Factory setting is 0.6 seconds.

Changing Settings, cont.

• Hi alert: Press the Hi Alert button until the desired level is

reached. Release the button.

• Low alert: Press the Low Alert button until the desired level is

reached. Release the button.

21



Manual Feed Settings

• Press and release the mode button to light theLED associated with the desired feeder to bemanually fed — ORP or pH.

• Press the “feed once” button. The desiredfeeder will go through one “set feed” timecycle. There is no manual feed option whenthe unit is in constant feed.

– (Manual feed will not work if cycle time is set at0.6 or ‘cont’)

22



Other Manual Information

• See the appropriate manual sections for:

– Setting the time-out feature

– Calibrating the pH sensor / probe

– Changing dip switches (pH/ORP interlock, feeder

time-out, acid/base and lockout)

23

Operation / Startup

• Do not add chemicals until all start-up operationshave been completed.

• Manually adjust the balance of the pool.

• Chemical levels: – pH 7.4 – 7.6

– free chlorine 1.0 – 3.0 ppm (700 mv ORP)

– Alkalinity 80 – 120 ppm

–Cyanuric acid 20 – 30 ppm

– TDS 300 – 2,000 ppm

– Calcium hardness 200 – 400 ppm

27



Operation / pH Settings

• Press and release the controller mode button

until the pH LED is lit.

– Select the desired set level.

– Select feed time cycle.

– Select upper and lower alert levels.

Note: It may take up to 24 hours for the sensors

to acclimate to the system.

28



Operation / ORP Settings

• Press and release the controller mode button

until the ORP LED is lit.

– Use a DPD test kit to measure free chlorine.

– Adjust the ORP set level to desired level.

– Select the desired set level.

– Select feed time cycle.

– Select upper and lower alert levels.

29



Operational Mode

• Press and release the mode button until the

“Auto” LED is lit. Note that this is the

operational mode for the controller. The

controller must be in this mode for thefeeders to maintain the desired parameters.

• Consider recalibrating the system after the

initial 24 hours as the sensors acclimate to thesystem.

30



Operational Mode, cont.

• Notes:

– The ORP is highly dependent on both the pH andthe cyanuric acid levels. Both of these variables

must be kept within acceptable ranges to maintainan acceptable relationship between the ORP andthe ppm of the sanitizer.

– When using the 55400 controller with Rola-Chem

pumps, the pump switch should be in the “on”position — not “timed” or “off.”
