The SVI II positioner receives an electrical position setpoint signal from the controller and compares theposition setpoint input signal to the valve position. The difference between the position setpoint and positionfeedback is interpreted by the position control algorithm and used to compute a new output pressure. Theoutput pressure is amplified by a pneumatic relay that drives the actuator. When the valve position value isequal to the value called for by the position setpoint input signal the system stabilizes with no further move-

Installation

Mounting the SVI IIThis procedure is used to mount the SVI II on Masoneilan rotary control valves that have less than 60degrees rotation, such as Camflex and Varimax.Required Tools

3/16 inch Hex Key with tee handle, 5/32 inch Hex Key, 3 mm, 4mm, 5mm Hex Key, 7/16 inch Wrench

1 Mount the SVI II rotary mounting bracket to the valve actuator using two (2) 5/16 - 18 UNC flat-head cap screws. The SVI II will be mounted as shown in Figure 2-3, ATO, or in Figure 2-4, ATC.In the preferred mounting position the long end of the mounting bracket is on your left when fac-ing the actuator for any position of the valve and actuator.

2. Bolt the extension shaft to the valve position take-off shaft using a 1/4 - 28 UNF socket flatheadscrew.

3. Due to internal valve pressure the plug shaft is pushed out to the mechanical stops, usually athrust bearing, during normal operating conditions. On valves where the valve position take-off ismounted directly on the end of the plug shaft, Camflex for example, the shaft must be bearing onits stops to properly set up the SVI II positioner. During hydrostatic testing the shaft is thrust to itsstop and a normally tightened packing will retain it in that position. If the shaft is in an unknownposition install a 1/4 - 28 UNF screw in the end of the shaft. Use the screw to pull the shaft out toits fully extended position. On vacuum service, the valve shaft may be drawn into the body by thevacuum acting on the shaft, but the magnetic coupling must be assembled flush with the mount-ing bracket with the shaft pulled fully out to its thrust bearing. Check that the endplay from thevacuum position to the fully extended position is less than 0.06 inches.

4. Slide the magnet holder into the extension shaft. The location of the magnets is in the ring of themagnet holder. The magnetic axis is the line through the center of both magnets.

5. Rotate the magnet holder so that the magnet axis is vertical when the valve is in the closed posi-tion. See Figure 2-2 and Figure 2-3.

6. Align the end of the magnet holder flush with the end of the mounting bracket. Secure the mag-net holder with two M6 set screws.

7. Slide the V-Seal over the magnet holder.8. Secure the SVI II onto the mounting bracket using four M6 x 20 mm Socket Head Cap Screws. 9. Ensure no interference exists with the position sensor protrusion. 10. Ensure that the V-Seal makes contact with the skirt around the position sensor protrusion on SVI

II housing.

Rotary - 90 Degree Model 33For actuators of 60 to 120 degrees rotation, follow instructions for Rotary Globe valves except mount the mag-net at plus or minus 45 degrees with the actuator de-energized as shown in Figure 2-5.Magnet Orientation on Rotary Valve ShaftsThe same mounting hardware is used for Camflex, Varimax, and Model 33 actuators. For each actuator typethe magnetic coupling must be properly oriented to the active sensing angle of the positioners Hall Effect sen-sor. See Table 2-1. The active range of the Hall-Effect sensor is plus/minus 70 degrees. If the total valve trav-el is less than 60 degrees, allowing a margin for tolerances, the best accuracy is achieved by mounting themagnet with the axis vertical in the valve-closed position. Note the location of the magnets in the ring of themagnet holder. The axis of the magnets is the line through the centers of both magnets. Mount the magnetholder with the magnet axis vertical on Camflex and Varimax, when the valve is closed. If travel of the valve exceeds60 degrees, the magnet must be assembled to the rotary valve shaft so that the magnet axis is vertical when the valve is at mid-scale. See Table 2-1.

Reciprocating Model 87/88 Multispring ActuatorThis section describes the procedure for mounting the SVI II on Masoneilan 87/88 Multi-Spring actuators.Tools required:

7/16 inch Combination Wrench (2 required)

3/8 inch Combination Wrench

1/2 inch Combination Wrench

3 and 5 mm Hex Keys

Phillips Head Screw Driver

Mounting the SVI II on a Multi-Spring Actuator1. Ensure that the lever is pinned to the magnet assembly and held securely by an M5 flat head

screw to ensure that the magnet axis is vertical when the lever is in the valve closed position.Tighten the lever screw securely.

2. Mount the SVI II reciprocating mounting bracket to the actuator using two (2) 5/16 - 18 UNC capscrews. The mounting location of the bracket depends on the size and stroke of the actuator.Refer to Figure 2 - 7 and Table 2 - 2 Reciprocating Valve Linkage Selection Table.

3. Select mounting hole A, B, C or D for the stroke of the valve. For example, hole B is shown inFigure 2 - 7 for a size 10 actuator with 1.0 inch stroke. Unless otherwise specified, the SVI IImounting assumes that the actuator is in the normal upright position. The mounting hole in theslotted opening of the mounting bracket must be left when facing the actuator with the actuatorin the upright position.

4. Thread the take-off rod to the actuator stem connector. Refer to Figure 2 - 9 Multispring Linkage.Ensure that the travel pointer located on the coupling is correctly positioned.

5. Attach the right hand threaded rod end to the SVI II lever using a 1/4 - 20 x 1 inch cap screw andnut as shown. The lever hole position to be used depends upon the specific valve stroke. Referto Figure 2 - 8 and to Table 2 - 2 Reciprocating Valve Linkage Selection Table.

6. Thread the R. H. lock nut and turnbuckle onto the R.H. rod end approximately two turns.Turnbuckle length is a function of actuator size, as shown in Table 2 - 2.

7. Secure the magnet housing assembly, including the lever and R.H rod end, to the bracket usingfour M5 X 10 mm flat head screws.

8. Attach the left hand threaded rod end to the take-off rod with 1/4 - 20 UNC nut and thread theL.H. lock nut onto the rod end.

9. Move the valve to its closed position. For air to extend, this requires using air pressure in the actu-ator to fully stroke the actuator. For air to retract, actuators simply vent the actuator of air pres-sure.

10. Thread the turnbuckle onto the left hand threaded rod end. Refer to Figure 2 - 9.11. Adjust the turnbuckle until the hole in the SVI II lever is aligned with the indicating hole in the

bracket. See Figure 2 - 1. Tighten both turnbuckle lock nuts.12. Mount the SVI II to the bracket and secure with four M6 socket head cap screws.13. Go to Chapter 3, CheckOut, Configuration, and Calibration and perform the operations to com

mission the SVI IIAdditional Actuator TypesWhen designing mounting hardware for other actuator types such as those listed below note that the feedbacklever of the SVI II is not internally spring loaded. The linkage must be designed to eliminate deadspace or play.If a pin and slotted lever is used, spring load the pin against the lever.

Assemble Tubing from Positioner to ActuatorThe SVI II Digital Positioner is designed to operate only with clean, dry, oil-free, instrument grade air toANSI/ISA-57.3 1975 (R1981) or ISA-S7.3-1975 (R1981).Single ActingThe supply and output connections for the SVI II, located on bottom of the pneumatic block, are tapped 1/4inch NPT. Output is toward the front, supply is toward the back. The exhaust connection for the SVI II, locat-ed on the relay body, is a tapped 3/8 inch NPT. Two pressure gauges, output on top, supply on bottom, arelocated on the front of the pneumatic block.

Maximum allowable air supply pressure to the SVI II varies according to actuator, valve size, and valve type.See Pressure Drop tables in valve specification sheets to determine the correct positioner supply pressure.minimum supply pressure should be 5 to 10 psi above maximum spring pressure.

Dew Point At least 18° F (10° C) below minimum anticipated ambient temperature

Particulate Matter Filtered to 5 microns

Oil Content Less than 1 ppm w/w

Contaminants Free of all corrosive contaminants

Installation

Do not use pipe thread sealant tape on pneumatic fittings. It may shred into small particles that can causeinstrument malfunction.

Never exceed the lower of actuator maximum rated supply pressure or 150 psig. (Double acting relay is 150psig also.) Damage to equipment or injury to personnel can result.

Remove any excess pipe thread sealant from the first and second threads to prevent uncured sealant fromentering the air lines.

Double Action Positioner

Principle of Operation.The D/A relay has a pair of opposed pneumatic outputs. When Output 1 delivers air to one side of the actua-tor, Output 2 vents air from the opposite side of the actuator piston. The volume of air trapped in each deter-mines the position of the actuator.

The Action (ATO or ATC) is applied with respect to Output 1. When Output 1 is connected to deliver air toextend the actuator, the action is ATC, on a down-seating valve. See Figure 2 - 11. If the piston actuator hassprings then the action of the positioner must match the action of the actuator.

* Assumes that valve closes, down seating, when the actuator extends. The terminology is reversed for anup-seating valve.

Balance PressureThe relay is designed so that at balance, without actuator force, the outputs are equal and both are at rough-ly 70% of supply pressure. During operation, when there is a valve stem load, with or without an actuatorspring, the pressure difference required to balance the actuator is automatically achieved by the relay deliver-ing air to oppose the force. The adjustment of this value can be altered by turning the Adjustable Seat assem-bly, P1.

The use of a Masoneilan filter regulator with a 5-micron filter is recommended for the air supply. Tubing usedbetween filter regulator, SVI II and actuator should be 1/4 inch minimum with 3/8 inch used for larger actua-tors. The use of a soft setting anaerobic hydraulic seal such as Loctite Hydraulic Seal 542 is recommendedfor sealing the pneumatic pipe threads. Follow manufacturers instructions.

Maximum allowable air supply pressure to the SVI II varies according to actuator and valve size and type. Seepressure drop tables in valve specification sheets to determine correct positioner supply pressure. Minimumsupply pressure should be 5 to 10 psi above maximum spring pressure.

Actuator PipingConnect Output 1, labeled “ACT 1” to the inlet port of the actuator in accordance with table 2 - 4. Output 2labeled “ACT 2” connects to the opposing actuator port.

Pre-Installation Issues

StorageIf the SVI II is stored, prior to commissioning and connection to a supply of clean dry air, you must keep thehousing sealed against weather, fluids, particles, and insects. To prevent damage to the SVI II :

Plug the ¼ NPT air connections, on the positioner and on the air filter regulator set.

Seal the vent.

Keep the housing covered and do not allow standing water to accumulate.

Observe storage temperature requirements.

Unpacking

Please exercise care when unpacking the control valve and its mounted accessories. In the SVI II containeryou should find a CD-ROM with ValVue 2 Lite, ValVue 2 Trial Version, and manuals.

Positioner Sensor PrinciplesThe motion of the control valve (position) is precisely transmitted to the SVI II by a pair of rotating magnetslocated outside the instrument housing. Rotation of a magnets is sensed internally by a Hall Effect sensor.Because the only connection through the case is a magnetic field there are no seals or bearings to wear orcorrode.

The rotation of the magnet is linked to the valve position by the mounting hardware provided. For a rotary con-trol valve the magnet assembly is normally attached directly to the actuator shaft. For a reciprocating controlvalve the mounting kit includes the magnet assembly mounted in a sealed bearing with a lever that must belinked to the valve stem.

The positioner must be installed with the gauges to the left and the housing display and cover to the right. The½ NPT conduit entry must be facing down to drain condensate away from the housing. The positioner can bemoved on the valve for best drainage depending on the position of the valve in the pipeline.

Inspect Actuator, Linkages, or Rotary AdapterVerify that the mounting has not been damaged in shipment for a premounted SVI II. Record thefollowing information for the configuration checkout:

Valve Air to Open (ATO) or Air to Close (ATC) Actuator pressure rating

Actuator bench range Inherent trim characteristic of the control valve; linear, equal percentage, or other. Refer

to valve data sheet or model number of control valve.

Verify Mounting and Linkage AdjustmentInspect the mounting and make any needed adjustments before running the positioner and checking the dig-ital configuration. Setting the magnet orientation must be approximately as shown. The two magnets are visi-ble within the magnet housing. The magnet must be aligned as shown in Figure 3 - 3 with Camflex or an actu-ator of less than 60 degree rotation or as in Figure 3 - 4 for 1/4 turn actuators. It is unnecessary to dismountthe positioner to check the magnet if ValVue 2 is available with a modem and PC.

Checking the MagnetUse this procedure to check the magnet using ValVue 2.

Connect to the positioner in accordance with the ValVue 2 instructions.Scroll to Read Raw Data from the command control box, Click Send CMD. The raw sensor value displays (in Raw position).Value should be between – 1000 and +1000 when a Camflex valve or reciprocating globe valve is closed.

. Value should be between –1000 and +1000 for a ball or butterfly valve when the valve is at midstroke.

Figure 3 - 3 Magnet and Lever Orientation for Reciprocating Valve

Note: Do not use Teflon pipe seal tape. The Teflon tape can shred into particles that are harmful to the pneu-matic components.

Do not remove the instrument cover or connect to an electrical circuit in a Hazardous Area unless the poweris disconnected.

To visually inspect the magnet orientation on a rotary valve remove the positioner from the bracket and com-pare the position of the magnet to the positions shown in Figure 3 - 1 or in Figure 3 - 2. It is not necessary toremove the positioner to visually inspect the magnet setting and linkage of a reciprocating globe valve. Theadjustable link must be parallel to the valve stem. Verify that the hole in the lever aligns with the indicating holein the bracket when the valve is in the closed position as shown in Figure 3 - 3. Check that the bracket ismounted on the correct holes. See Table 2 - 2, Reciprocating Valve Linkage Selection.Connect the Air SupplyUse this procedure to connect the air supply.

Connect a supply of clean, dry compressed air to the filter regulator.

Recommended tubing size is 1/4 inch (3/8 for large actuators).

Inspect the tubing connections between the filter-regulator and the positioner for leaks.

Verify that the tubing is not bent or crushed.

Verify that all fittings are leak tight

Turn on the air supply.

Adjust the filter regulator.

Supply pressure must be a minimum of 5 psi greater than the spring range of the actuator but may not exceed the rated actuator pressure. Refer to the valve instruction manual.

This operation causes the valve to move. Before proceeding ensure the valve is isolated from the process

Use of a low impedance voltage source will damage the SVI II. The current source must be a true high imped-ance current limiting device. A proper current source explicitly enables adjustment of the current in mA, notVolts.

Connect to Current SourceConnect to a DC mA current source then check and configure with the local display and pushbuttons, if soequipped. The following section describes configuration and calibration with the optional local display andpushbuttons. If the SVI II is not equipped with local display use ValVue 2 Lite and a PC with a HART modemor a HART Handheld Communicator. See Introduction to ValVue 2

Pushbutton Locks and Configuration-Lock JumperBefore performing any of these functions with the local display you must first ensure that the pushbuttons areplaced in the unlocked mode using ValVue 2 Lite. The positioner ships in the unlocked mode. See ValVue 2documentation for more details.

The SVI II offers several levels of plant security. It may be desirable, after initial setup, to lock the pushbuttonsso that the SVI II parameters cannot be inadvertently changed from the buttons. Several levels of software set-table pushbutton locks are provided. See table 3 - 1.

Level AccessSecurity level 3 Allow Local Buttons: Buttons on the SVI are fully enabled.

Security level 2 Lock Out Local Calibration and Configuration: Use the buttons to performoperations in normal operating mode and manual mode. Do not go to config-ure or calibrate mode.

Security level 1 Lock Out Local Manual: Examine variables in normal operating mode but donot put the valve in manual operating mode. Access to calibrate or configuremodes is not available.

Security level 0 Lock Out All Buttons: The buttons are disabled (level 0).

Table 3 - 1 Pushbutton Lock Security Levels

Note: When an SVI is turned on it is advisable to apply the air supply before applying the electrical input sig-nal.

Hardware Configuration LockAdditional security is achieved using the hardware configuration-lock jumper shown in Figure 3 - 4. When setto secure position, shorting the two-pin header, configuration and calibration are not permitted by the localinterface or by remote communications. Pushbuttons, ValVue 2.0 and HHC 275 are locked out, except toexamine configuration, calibration, and position. This is similar to Security Level 1 in Table 3 - 1.

Powering Up1. Loosen the four (4) cover screws and remove the cover of the SVI II. Connect the +/- terminals

to the current source + to + and - to -. See Figure 3-4. Reinstall the cover and display.2. Adjust current to 12 mA. The LCD display should indicate COLD R for approximately 2 seconds

followed by the firmware version number.3. Following RESET, when the instrument was powered off in OPERate mode, the display alter-

nately displays position POS % and input current SIG mA. If the positioner was powered off in the MANual mode then it will start up in MANual mode.

4. The display alternately displays position (POS-M) % and input current (SIG) mA. The horizontalbar displays the valve position in a percentage format.

5. If Pos-M is displayed, press +, CONFIGure is displayed. Press + CALIBrate is displayed. Press + OPERate is displayed. Press * to continue testing in OPERate mode.

6. When the instrument is properly configured the valve moves to 50% open and the displayreads approximately 50%.

7. Stroke the valve to the closed position and the open position by adjusting the current to 4 mAand 20 mA. Confirm that the valve moves properly.

Pushbuttons and Local DisplayThis section covers the optional local interface consisting of the LCD alphanumeric display and pushbuttons.Operation of the SVI II Positioner as a local device is controlled through the optional device-mounted pushbut-tons and digital display, shown in Figure 3 - 8. Using the display you can read the input signal, valve position,and actuator pressure. The display sequences from one variable to the next every 1.5 seconds.

Note: If the SVI II is specified without local pushbuttons and display, local operation is not available.Configure and calibrate with ValVue 2.0 Lite and a HART modem.

This process can cause the valve to move. Before proceeding be sure the valve is isolated from the process.Keep hands clear from moving parts.

Using the pushbuttons you can exit from operating mode at any time and step through a menu structure toperform a wide range of manual operation, calibration, configuration, and monitoring functions that aredescribed later in this section. ValVue 2 is used to perform all diagnostics functions. The pushbuttons do notsupport diagnostics functions. The SVI II has two operational modes: Normal Operating Mode and Manual Mode and two setup modes,Configuration and Calibration. The SVI II also has two modes for handling of faults and power-up: Reset andFailsafe. For a complete description of the operation of the positioner with remote communications and withlocal pushbuttons refer to Chapter 4 .

3 - 7


PushbuttonsThe local pushbuttons are located behind a hinged cover, directly below the display window. To open the coverloosen the screw and swing the cover down. Always refasten the cover after use to protect the pushbuttonsfrom environmental contamination.The three pushbuttons perform the following functions:

Left Button - Marked with *, permits you to “select” or “accept” the value or parameter optioncurrently displayed.

Middle Button - Marked –, permits you to move back through the menu structure to the previ-ous item in the menu or decrement the value currently shown in the digital display. If used todecrease a displayed value, holding the button down causes the value to decrease at a fasterrate.

Right Button - Marked +, permits you to move down through the menu structure to the next itemin the menu, or to increment the value currently shown in the digital display. When used toincrease a displayed value holding this button down causes the value to increase at a faster rate.

Figure 3 - 8 Local Pushbuttons

Note: You must return the mode to “*OPER” to put the instrument into normal OPERating mode. The position-er will not respond to setpoint if left in MANual. RESET returns the positioner to the mode active, prior to reset.

When commissioning or checking a control valve with SVI II fully installed the following steps are recommend-ed:

Change mode to Manual mode

Examine and adjust all CONFIGuration items

Enter Calibration mode

Run STOPS to automatically calibrate stroke

Run autoTUNE to set dynamic response

Quick-Start Check-Out and Configuration with HARTThis section covers a subset of the functions available with HART. For a complete description refer to Chapter4 Using the Digital Interfaces. If the SVI II is not equipped with optional pushbuttons and local display thecheckout and configuration is performed using the standard HART communications interface. In addition to thefunctions performed with the local pushbuttons additional functions are performed with HART. For example,the instrument tag descriptor is written and stored in non-volatile memory and used for point to point wiringcheckout.ValVue 2 LiteValVue 2 Lite is the most complete and easiest to use configuration tool. ValVue 2 Lite is provided with eachSVI II. Connect the modem and PC to the SVI II as shown in Figure 3 - 10. Be sure that the configuration lockjumper is in the unlock position. When the jumper is in the lock position, shorting the two pin header, ValVue2 Lite is not permitted to make any changes. Parameters, however, are readable. See the ValVue 2 manualfor complete details. It is included on the ValVue 2 CD-ROM. In this section, we recommend a few ValVue 2Lite steps to checkout and configure a pre-installed SVI II on a control valve.

Chapter Four - Using the Digital Interfaces

Communication, Configure, and CalibrateThis section describes three ways to communicate, configure, and calibrate SVI II. The Smart Valve Interfaceis indeed a smart device capable of:

Streamlining the operation of the valve positioning function

Providing diagnostic information

Improving precision of process control

Communicating critical information locally and remotely. The three available communication tools offer increasing levels of functionality. Local Display and Push ButtonsMost basic and easiest is the local pushbutton and display option mounted on the SVI II. It is available at anytime and provides immediate local access to most configuration, calibration, and fault messages. It is approvedfor use in Explosionproof and Intrinsically Safe installations in Hazardous Areas in accordance with AppendixC, Intrinsic Safety Wiring Diagrams and Control Drawings.HART Handheld CommunicatorThe HART handheld communicator is a universally available tool that provides all the accessibility of the localbutton and display. The HART tool has the functionality to upload and download configurations, enter alphanu-meric messages and set the custom characteristic numerical parameters. The HHC 275 is approved forIntrinsically Safe use in Hazardous Areas in accordance with SVI II Approvals and in accordance with the HHCapprovals. See Appendix C and Chapter Six for additional information concerning this device.ValVue 2ValVue 2 combines the power of the PC with the features of the SVI II for ease of use and automation of posi-tioner operation and full access to all data. ValVue 2 Lite is provided with all SVI II positioners and is recom-mended for service and maintenance where a PC or laptop is permitted. See Chapter Six.Pushbutton GuideThe three pushbuttons perform the following functions:

Left Button - Marked with *, permits you to select or accept the value or parameter option currently displayed

Middle Button - Marked –, permits you to move back through the menu structure to the previ-ous item in the menu, or to decrement the value currently shown in the digital display. When usedto decrease a displayed value, holding this button down causes the value to decrease at a fasterrate.

Right Button - Marked +, permits you to move down through the menu structure to the next itemin the menu, or to increment the value currently shown in the digital display. When used toincrease a displayed value, holding this button down causes the value to increase at a faster rate.

To determine how to display and select a specific parameter value or configuration option, refer to the menustructure diagrams shown in figures 4 - 1 thru 4 - 4. When using these diagrams as a map you can movethrough the menus to the function you needed.

Note: If the pushbuttons are pushed after being locked by ValVue software, the message “LOCKED”appears. Please refer to the ValVue 2 User’s Guide for instruction about unlocking the pushbuttons.The following pages display the menu structure for operation the SVI using local pushbuttons.

DIgital Interfaces

Normal OPERate Mode and MANual Mode Menus

When you leave the normal OPERate mode to go to MANual mode the valve is placed in the last position itwas in when it left normal OPERate. When in the MANual mode the device does not respond to the 4-20 mAsignals. However, the SVI unit can still respond to HART commands, including HART commands to positionthe valve. When you switch to VIEWDATa or VIEWFauLTs menus from the normal OPERATE MODE MENUthe valve is still in normal OPERate mode and still responds to the 4-20 mA signal.

DIgital Interfaces

Single Acting / DoubleActingThe positioner must be con-figured for a single or doubleacting relay. The parameteris toggled by the * pushbut-ton.

ATO / ATCThe positioner must be con-figure as Air-to-Open, ATO,or as Air-to-Close, ATC. Thisparameter is toggled by the *button. If the positioner hasa double acting relay, theaction is defined for the out-put labeled ACT1, or Output1. To determine if a directacting positioner is consid-ered ATO or ATC perform thefollowing test:

Apply the actuators rated pressure to the positioner supply. Do not exceed actuator pressurerating on the control valve specification sheet. Damage to the valve stem or shaft can occur.Disconnect the electrical (4 to 20 mA) input signal from the positioner or set it to less than 3.6mA.Observe the position of the control valve. If it is closed the actuator is ATO. If the valve is openit is ATC.

DIgital Interfaces

Valve CharacteristicsThe positioner must be configured to supply the correct relationship between input signal and valve position.This is called the position characteristic. Table 4 - 1 lists guide lines for configuring the positioner character-istics. Use of a linear characteristic is recommended unless the process dynamics or control valve applica-tion calls for an alternate characteristic. SVI II offers a custom characteristic for specialty applications. Priorto selection of custom, the 10 parameters for the custom characteristic must be entered using ValVue 2.

Pressure UnitsSelect the display units for the optional actuator pressure sensor . The available choices are PSI, BAR or KPA.The choice applies to both the local LCD display and to the displays with ValVue 2 or the HART Handheldcommunicator.

Press * to move from PSI to BAR to KPA.

Press + to continue to scroll through the config menu.

Tight ShutoffTight Shutoff is an optional performance feature that prevents leakage at the closed position. Without this fea-ture, at the closed position with an input signal of 0%, the valve may be forced tight against the seat with max-imum available actuator force or it may be only touching the seat with minimum force. In either case, it is undercontrol. To prevent leakage that can occur in the second case, configure TS ON and set a value of position setpointbelow which the actuator will apply maximum seating force. As the position signal drops toward the TS valueSVI II will move the valve to the TS position value. When the position reaches the TS value SVI II applies max-imum actuator force. The TS function has 0.5% deadband to prevent chatter. If TS is set ON at 2%, for example, then the valvebegins to open when the setpoint reaches 2.5%.

Configuring TS ON

Press * to turn TS ON.Press + to increase TSPress - to decrease TSPress * when finished to return to the CONFIG menuThe CONFIG menu displays TS ON

SVI Administration ProgramIn a plant with many users with various levels of training, it is often desirable to allow certain users access toa limited range of functions. The ValVue 2 program requires a password for each user. This password deter-mines what functions of the program the user is allowed to access.

The SVI Administration program allows the plant to establish passwords and privilege levels for each user thatmay use the ValVue 2 program. The program has been written assuming that each plant (or department of theplant) will assign an administrator who would be responsible for installing the ValVue 2 software, assigningpasswords and setting up the password files. In this way, access to the SVI II can be controlled.

The ValVue 2 software is provided with on-line context sensitive help, and is accompanied on the CD-ROM bya software instruction manual. It is recommended that the user click Help to refer to the online instructions,after installing the software on the PC. In the table of contents menu, click on any topic to open the window.Click on any control button or data window to view the explanation of that feature.

Chapter Five - Wiring an SVI II

OverviewThe SVI II is used as a current loop device drawing power and analog input signal from a precision currentsource. The following sections describe HART digital communications using the 4 to 20 mA current mode.

System ConnectionsAll system connections must comply with the HART Communications Protocol Specifications. For completetechnical information refer to the HART Communications Foundations Document Number HCF-SPEC-11 andthe references. The SVI II is a HART compliant device of type Actuator. It is therefore a receiver of 4-20 mA,and cannot have a voltage source applied to its input terminals.

When installing the SVI II in a 4-20 mA current loop, the engineer designing the loop must consider a set ofconflicting electrical requirements. The control signal to the positioner is a 4 to 20 mA current generated by thecontroller or DCS and transmitted to the positioner located remotely in the field. The electrical characteristicsof a current loop sending a signal to the field device are different from the apparently similar loop bring a sig-nal to a controller from a transmitter in the field.

The positioner receives its power from the current signal. It receives its control setpoint from the value of thecurrent and it must be able to communicate bi-directionally by superimposing signal tones upon the currentsignal without distorting the current signal, without the tones being affected by the electrical characteristics ofthe current signaling device. All these conflicting requirements must be met with equipment manufactured byvarious manufacturers, and work with long cables, in a noisy hostile plant environment. Energy levels are oftenlimited for safe installation in explosive environments. Special engineering may be required to meet the signal-ing requirements at low energy levels.

The following will not cover all the details for a successful installation, in all cases. That is beyond the scopeof this instruction. It will suffice to explain the requirements as a guide use to obtain necessary componentsfrom many sources for a successful installation.

Do not connect a HART modem and PC to a control circuit unless the controller is HART compatible or hasa HART filter. Loss of control or a process upset may occur if the controller output circuit is not compatiblewith HART signals.

Install in compliance with Hazardous Area rules in accordance with local electrical codes and plant stan-dards by trained specialists.

Do not connect a PC or HART modem to an intrinsically safe circuit except on the safe area side of the bar-rier. Do not operate a PC in a hazardous area without compliance with local and plant regulations.

Note: A control circuit must be HART compatible or have a HART filter installed. Contact the manufacturersof the controller or DCS. See HART Filter Required for Certain Control System Output Circuits in ChapterSix..

Wiring an SVI II

Wiring GuidelinesThis list contains eight guidelines for a successful implementation of DC current signal, DC power, and HARTcommunication to the SVI II:

Compliance voltage at the SVI II must be 11.2 volts at the maximum current of 20 mA. Signal to the SVI II must be a well-regulated current in the range 3.8 to 22 mA. Controller output circuit must be unaffected by the HART tones which are in the frequency

range between 1200 and 2200 Hz. Frequency range of the HART tones must have a circuit impedance of more than 220 Ohms,

typically 250 Ohms. HART tones may be imposed by the positioner and a communication device located anywhere

on the signaling circuit. Capacitance of the signaling circuit may not exceed about 0.26 microfarads or with high series

resistance 0.10 microfarads. Cabling must be shielded to prevent electrical noise that would interfere with the HART tones,

with the shield grounded at only one location. Signal must be properly grounded in only one place.

For details and calculation methods for wiring resistance, and capacitance and for calculation of cable charac-teristics please refer to the HART® FSK Physical Layer Specification.

System Description-PositionerTypical system setups are shown in Figure 5-1 General Purpose and Explosionproof (EEx d) InstallationSchematic and Figure 5-2 Intrinsically Safe Installation Schematic. The SVI II positioner can be located in ageneral-purpose or hazardous area protected by explosionproof (EEx d) methods. Wiring diagrams are gen-eralized, actual wiring must adhere to Electrical Installation section of manual and local electrical codes.

The use of a Handheld Communicator or a HARTmodem is not permitted in the Hazardous Areaprotected by explosionproof (EEx d) methods. InFigure 5-2 the SVI II positioner is located in ahazardous area that is protected by IntrinsicallySafe wiring practices. The SVI II requires an elec-trical input from a 4-20 mA current source.

The SVI II input signal can carry a HART commu-nication protocol signal from ValVue 2.0 softwareand a HART modem or from a HART Hand HeldCommunicator. Because the process control sys-tem, the input signal source, is located in a non-hazardous location, an intrinsic safety barrier mustbe placed between the controller and the SVI II.Alternatively the system can be installed as explo-sionproof / flameproof.

SVI II can communicate with a remote PC running ValVue 2 software via a modem connected to the PCs seri-al port. The PC, which is not intrinsically safe, must be connected to the circuit on the safe area side of theintrinsic safety barrier if the valve is located in a hazardous area.

The SVI II can be operated, calibrated, configured, and interrogated either by using local pushbutton and dis-play, or by using a remote PC running ValVue 2 software or with the HART Hand-held Communicator. TheHART Handheld Communicator is approved for Intrinsically Safe use in accordance with FM and CENELECstandards. Read and observe all HHC labeling. The SVI II is polarity sensitive so the positive lead must be con-nected to the positive (+) terminal and the negative lead to the negative (-) terminal. Reversal of input will notcause damage but the unit will not function.

Wiring an SVI II

The following three tables are examples of calculating the compliance voltage necessary to supply 11.2 voltsto the SVI II at 20 mA.

Table 5 - 1 Compliance Voltage Example 1 - Single Channel Zener Barrier and 3000 Feet of 22 AWG Cable

Voltage at SVI II at 20 mA 11.2

Drop in single channel zener barrier with 342 ohms end to end resist-ance

6.84

Drop in 22 AWG cable 3000 feet long (30 Ohms per 1000 feet) 1.8

Drop in passive HART Filter* 0.0

Voltage required at controller 19.84

Conclusion: In Table 5 - 1 the control system must have a compliance voltage equal to or greater than19.84 volts; contact the DCS vendor to verify compliance.

Note: Improperly or inadequately grounded installations can cause noise or instability in the control loop. Theinternal electronic components are isolated from ground. Grounding the case is unnecessary for functionalpurposes but grounding the case may be necessary to conform to local codes.

Grounding PracticesTo ensure proper grounding make sure thatcase, signal, and ground connections are madein compliance with the plants normal groundingpractices. Any point in the loop can be refer-enced to ground, but there must never be morethan one ground point. Normally ground is con-nected at the controller or at the intrinsic safetybarrier.

The case grounding screws are located on theoutside of the case at the lower right of the dis-play cover and inside the cover. The case is iso-lated from all circuitry and can be groundedlocally in accordance with applicable codes.

If noise or instability is present set the positionerto MANual mode of operation and manuallyposition the valve over it’s entire range. If thevalve is stable in MANual mode then the prob-lem can be noise in the control system. Recheckall wiring connections and ground points.

Compliance Voltage in Single Drop Current ModeWhen operated with input current, the loop controller, or any other current source, must be capable of supply-ing 4 - 20 mA with an output voltage compliance of at least 11.2 V at the SVI II. The available output voltagefrom a current source is reduced by the loop wiring resistance and any other resistive devices such as barri-ers and filters. This is checked by connecting a resistor of value 600 OHMs loop resistance across the outputof the current source and verifying that 20 mA is obtainable at full scale output.

Conclusion: In Table 5 - 3 the controller must have a compliance voltage equal to or greater than 18.5volts.

Wire Size and ConduitElectrical connections are made to the electronics module terminal board as shown in Figure 5-1. Theterminals will accept wire sizes up to AWG 14. The SVI is supplied with two 1/2 inch NPT conduit entries. M20adapters are available. Internal and external ground terminals are provided for use if grounding is required.

HART Physical Layer Compliance of the Control SystemCommunications to a SVI II requires a HART-compliant communications loop. The HART protocol specifiesthe noise level, impedance requirements, and configuration of the loop. The controller or output card of thecontrol system must comply with the Physical Layer Specification.Impedance ConstraintsHART communication is based on the talking device generating an AC current superimposed on the 4-20 mAcontrol signal. Two frequencies are generated; 1200 Hz representing the digital value “1” and 2200 Hz repre-senting the digital value “0”. The listening device responds to the voltage generated when the AC current flowsthrough the loop impedance. In order to generate a voltage from a current there must be impedance. HARTProtocol requires that this impedance be at least 220 Ohms at the tone signaling frequencies.

HART compliant current sources are supplied with the correct Impedance Versus Frequency Characteristic. InNon-Compliant Current Sources there may be a noise reduction capacitor across the output that lowers theimpedance at higher frequencies and thus lowers the signaling voltage. To be certain that at least 220 Ohmsof impedance is presented by the current source a resistor can be added in series with the current source. Thisreduces the effective compliance voltage of the current source by 20 mA times the value of the series resis-tor. See Example 3. An added resistor is unnecessary during tests with high impedance current calibratorssuch as the Altek Model 334 Loop Calibrator.

Note: When an intrinsic safety barrier separates the SVI II from the modem or HHC a HART compliant barri-er must be used. See Chapter Six for details.

5 - 5

Wiring an SVI II

Noise ConstraintsHART Communication depends on converting two frequencies (1200 and 2200 Hz) into digital values “1” and“0”. Noise can cause errors in the conversion. Conventional good wiring practice, such as use of twisted shield-ed pair cable with the shield and signal loop grounded at only one point, minimizes the effects of noise.

Cabling and Interconnection Requirements

Interconnections are made using shielded twisted pair cables. The shield is connected to ground at one pointonly. The signal loop is grounded at only one point in accordance with plant electrical standards. It is custom-ary to ground the signal at the controller or intrinsic safety barrier. The SVI II is supplied with two 1/2 inch NPTconduit entries. M20 adapters are available. Internal and external ground terminals are provided for casegrounding requirements.

Capacitance vs. Length of Cable for HARTThe HART Communications Foundations specifies cable capacitance requirements to preserve signalstrength. Refer to the standards for detailed calculation methods. See Note 3 at the end of the manual.

HART Filter Required for Certain Control System Output CircuitsSVI II is intended for use with all control systems. However, output circuits of several major DCS systems areincompatible with the tones used for HART signals. You must verify that the DCS or controller works reliablywith the HART protocol. When the DCS is incompatible an external HART filter must be installed between thefield wiring and the output card. MTL manufactures the HART filter HCU16AO. It is a 16 channel DIN railmounted device composed of passive circuitry that introduces negligible voltage drop. For additional information, contact MTL.

Split Range ApplicationsThe SVI II is designed to operate in split range configurations supporting up to three control valves connectedto a single controller output. Minimum input current span for each SVI II is 5 mA. For each positioner the upperrange value is between 8 and 20 mA and the lower range value is between 4 and 14 mA. For example, threedevices might be configured with input current ranges of 4-9 mA; 9-14 mA, and 14-20 mA. Split range operation with SVI II requires special consideration of the compliance voltage. The SVI II requiresat least 11.2 Volts. Two SVI II in series requires at least 22.4 Volts in addition to the voltage drops in wiring andother series devices. Typical controller output current sources rarely deliver 24 Volts, so the system canbecome voltage starved. It is possible to boost the compliance voltage of the DCS using a series wired volt-age source power supply, as shown in Figure 5-6. The total loop voltage must not exceed the rating for thecontroller output current source. The DCS vendor should be contacted to validate this approach.

Install the SVI II in accordance with local and national code in both general and hazardous area locations.Substitution of components can impair suitability for use in hazardous locations.

Note: A control circuit must be HART compatible or have a HART filter installed. Contact the manufacturer ofthe controller or DCS. See HART Filter Required for Control System Output CIrcuits.

Do not connect a HART modem and a PC to a control circuit unless the controller is HART compatible or hasa HART filter. Loss of control or a process upset can occur if the controller output circuit is not compatible withHART signals.

Note: The internal electronic components are isolated from ground. Grounding the case is unnecessary forfunctional purposes. Grounding the case may be necessary to conform to local codes.

Wiring an SVI II

Setting Loop Addresses for Split RangedSystemsWhen more than one positioner is installed in asingle current loop, the HART loop address ofeach device must be set to 1, 2, or 3 (or othernon-zero values) to allow a HART master torecognize each SVI II when connected to allthree devices on a single current loop. Do notuse “0” for any of the positioners. A “0” maycause HART masters to stop searching for addi-tional positioners.

Both the ValVue 2 software or the HARTCommunicator 275 can be used to set non-zeroaddresses. ValVue 2 must be configured toallow multidrop mode, by using the OPTIONSbutton in the SELECT DEVICE screen.

ValVue supports HART devices, including SVIs, with non-zero polling addresses and supports multiple SVIson the same loop, for split ranging. To enable this support, check the Multidrop box. If unchecked, ValVue willlook for devices only at polling address 0. When in multidrop mode, even if a device is found at polling address0, other polling addresses are searched.Multiple Output Circuit Control SystemDCS systems offer multiple independent analog outputs driven by the same control signal to solve the voltageproblem with split ranged positioners. Use of such systems is recommended for split range applications. TheHART address of each SVI II will be “0”.IsolatorsAnother solution is to use an Intrinsic Safety Isolator for each loop. A number of manufacturers make suitableisolators designed for use with HART output circuits. Using an IS Isolator allows up to three SVI II to be oper-ated from a single 4/20 mA DCS output. Each isolator has a low compliance voltage input requirement and ahigh voltage output capacity.

Up to three isolators can be connected in series to a single controller output and each of them can drive a posi-tioner. Isolators are used to provide compli-ance voltage and isolation even in installa-tions not requiring intrinsic safety. An exam-ple of an isolator can be obtained from R.Stahl, (Model 9318/16-22-10). Consult themanufacturer for detailed installation instruc-tions.

The HART loop address of each device mustbe set to 1, 2, and 3 (or other non-zero val-ues) to allow a HART master to recognizeeach SVI II when connected to all threedevices on the safe area side of the multipleisolators. Do not use “0” for any of the posi-tioners. A “0”causes HART masters to stopsearching for additional positioners.

Figure 5 - 5 Split Range with Supplemental Power SupplySupplemental Power SupplyAnother approach is to boost the compliance voltage of the DCS using a supplemental power supply (seeFigure 5-6) with the split ranged SVI II positioners connected in series with the supply. It is not practical to usesupplemental supplies when Intrinsic Safety is required. The barriers do not permit adequate voltage. Contactthe DCS vendor to verify that the output circuit is compatible with the added voltage. The supplemental volt-age must equal 11.2 volts for each additional SVI II. Exceeding the values in Table 5-4 causes damage if thesignal wires are short-circuited.

Verify Wiring and ConnectionsAdditional constrains on the split range system is that the minimum span must be 5 mA. The upper range valuemust be 8 mA to 20 mA. The lower range values must be 4 mA to 14 mA. Use the following procedure to ensure that the SVI II is properly powered:

Connect a DC voltmeter across the input terminals.

For an input current value between 3.8 and 22 mA the voltage must be between 10.5 and 11.2V.

Current is read from the local display or with a milliammeter installed in series the SVI II.

When voltage exceeds 11.2 V check that polarity is correct.

If voltage is less than 9.5 volts and polarity is correct, voltage compliance of current source isinadequate.

Connect a milliammeter in series with the current signal. Verify that source can supply 20 mA toSVI II input.

If 20 mA is not attainable, see troubleshooting.

Wiring an SVI II

Required Practices for Explosionproof (Flameproof Ex) Installations

The SVI II is provided with two threaded conduit entries. All wiring must be installed with approved conduit andapproved seals or with approved cable and cable glands according to local codes. The unused conduit entryis plugged with a ½ NPT pipe plug. Thread engagement must comply with local electrical codes. The covermust always be secured before application of power.

Do not connect a HART communication device in the hazardous area. Use of the SVI II local display with push-buttons is recommended when Explosionproof methods are in effect.

Clarification of TerminologyIn Factory Mutual Research and Canadian Standards Association codes, Explosionproof means use ofapproved enclosures and conduit enclosed cables, but in CENELEC countries, this method is calledFlameproof. In CENELEC countries, Explosionproof means both Flameproof and Intrinsically Safe.

Recommended Practice for Severe or Humid Environments

The circuitry of SVI II is encapsulated for protection from corrosive atmospheres. To prevent moisture fromdamaging the electronics of the SVI II use a sealed junction box in high humidity or tropical environments. Thewiring from the junction box to the SVI II is sealed by flexible cable with a cable gland or with a potted nippleand pigtail where applicable codes permit.

Chapter Six - Using HART Communications withIntrinsic Safety

OverviewWhen an SVI II is installed in a hazardous area in accordance with the applicable codes and standards forIntrinsic Safety there are wiring considerations for successful operation in addition to the requirements for safe-ty. The choice and application of intrinsic safety barriers requires special training. For additional information,consult MTL Instruments PLC Measurement Technology Limited: www.mtl-inst.com or R.Stahl, Incwww.rstahl.com.

All installations must comply with plant standards and local and international electrical codes. All intrinsicallysafe installations must conform to the requirements listed in Appendix 3 for FM, CSA, and CENELEC.

There are 3 basic barrier types: Single channel zener diode barriers

Dual channel zener diode barriers

Active galvanic isolators.

To determine if the installation will perform successfully with HART communications you must considere HARTfilter requirements and HART barrier compliance.

HART Barrier ComplianceThe intrinsic safety barrier must bedesigned to transmit the HART signalsin both directions. Both passive zenerdiode barriers and active galvanic isola-tors are offered with HART compliance.Consult the manufacturer or refer to thedocuments listed at the end of thisinstruction manual.

Figure 6 - 1 Intrinsically Safe Installation Schematic withZener Barrier and HART Filter

HART Communications

Output Channel Isolation

The designer of the signaling circuit where the SVI II is to be installed must consider the 8 design rules inWiring Guidelines. In particular, the control system output interface has analog output channels that are gal-vanically isolated and share a common ground or are separated from ground by the current control transistoror sense resistor.

If the outputs are isolated a single channel zener diode barrier can be used.

If the outputs share a common ground a single channel zener diode barrier can be used.

If the outputs are separated from ground a dual channel zener barrier is required.Controller outputs are separated internally from ground by a current sense resistor or a control transistor. Dualchannel barriers apply excessive loop resistance and cause compliance voltage problems. An intrinsically safegalvanic isolator operates with all three types of output channels, isolated, grounded or separated from ground,and provides sufficient compliance voltage. The galvanic isolator must be certified by the manufacturer to beHART compliant if the HART connections are supported on the safe area side of the isolator. See Figure 6-2.Consult barrier and isolator manufacturer for devices rated for use with the SVI II positioner I.S. entity param-eters in Hazardous Area Approvals.HART Filter RequirementsThe control system output interface mustallow the HART frequencies to coexist withthe precision 4- 20 mA DC signal. Circuitsthat are not designed for HART may need aHART filter. Consult the controller or DCSmanufacturer for interfacing to a particularsystem. The HART communications cancause a non-HART-compliant output circuitto malfunction, in some cases. In othercases the HART communications tones aredisabled by the control circuit.

The SVI II can be used with non-HART com-pliant output circuits but remote communica-tions functionality are not enabled.

Use pushbuttons for all operation and main-tenance. If remote maintenance is desiredalways isolate the control valve from theprocess and disconnect the non-compliantcontroller before connecting a currentsource for power and a HART masterdevice.

If a HART filter is required, then its voltagedrop must be considered in calculating thecompliance voltage.

Figure 6 - 2 I. S. Installation with Galvanic Isolator

Do not connect a HART modem and a PC to a control circuit unless the controller is HART compatible or hasa HART filter. Loss of control or a process upset can occur if the controller output circuit is not compatible withHART signals.

Note: A control circuit must be HART compatible or have a HART filter installed. Contact the manufacturer ofthe controller or DCS. See HART Filter Required for Certain Controls System Output Circuits.

HART Communications

Use of a Modem and Computer in Intrinsically Safe CircuitsMany HART modems that are in use today are not approved for connections to Intrinsically Safe control cir-cuits. Most portable computers are NOT approved for use in hazardous areas. Modems can be safely con-nected to the safe area side of barriers, and isolators. Observe requirements for HART filter.MACtek Intrinsically Safe modem, Model 010005 The VIATOR RS232 HART Interface [Eex ia] IIC complies with the Essential Health and Safety Requirementsrelating to the design and construction of equipment and protective systems intended for use in potentiallyexplosive atmospheres.

Use of Handheld Communicators In Intrinsically Safe CircuitsThe HART Communicator 275 is approved to communicate with intrinsically safe control circuits in hazardousareas. Read the product Manual for the HART Communicator. Observe all warnings. The intrinsic safety enti-ty parameters must be added to the SVI II entity parameters to determine suitability for use in any intrinsical-ly safe circuit. Observe the labels on the HHC or consult the manufacturer.

Do not connect a PC or HART modem to an intrinsically safe circuit except on the safe area side of a barrier.Do not operate a PC in a hazardous area without compliance with local and plant regulations.

The HHC 275 is not approved for use in hazardous areas that use explosion proof safety practices. Do notuse the HHC 275 unless the area has been declared safe (Hot Work Permit).

Chapter Seven - Principles of Operation

Principle of Operation

Intelligent ElectroPneumatic Positioner with HART communication

The SVI II ElectroPneumatic Valve Positioner receives an electrical position setpoint signal from a controlleror other device and compares the position setpoint input signal to the valve position. The difference betweenthe position setpoint and position feedback is interpreted by the position control algorithm. This is used to com-pute a new output pressure. This output pressure is amplified by a pneumatic relay that drives the actuator.When the valve position agrees with the value called for by the position setpoint input signal the system sta-bilizes with no further movement of the actuator.

Physical Description

The SVI II is housed in an industrial, tough, weatherproof, corrosion resistant aluminum housing that has beendesigned for operation in hazardous areas as listed in Appendix B . Electrical connections are made throughtwo 1/2 inch NPT conduit entries. Pneumatic connections are made through two or three ¼ inch NPT ports.

Figure 7 - 1 Block Diagram with D/A Converter and Pressure Sensor

Operation and Maintenance

Electronics ModuleThe Electronics module is an electronic circuit encapsulated in a die-cast aluminum housing. The electronicsinclude a multiplexer, A/D, D/A, HART modem, temperature sensor, Hall-Effect magnetic position sensor, amicro controller, and a power management/distribution circuit. The programs controlling the SVI II positionerare stored in a flash memory that allows for the downloading of upgraded firmware.

A separate non-volatile memory stores configuration information, and continuous diagnostic results. Expansioncapabilities include connectors for the addition of the optional local display with pushbuttons, pressure sensorsand optional output interface module. Using the internal programmed positioner algorithm, the CPU computesthe required output based on information received from the measurement sensors. The base module has nouser repairable components.Magnetic Position SensorA non-contact sensor uses a magnetic field to transfer the position through the wall of the housing, withoutpenetration, to sense the valve position. A Hall effect device, sealed within the electronics housing, senses therotation of a magnetic assembly mounted on the end of a rotary valve shaft or on a driven linkage mounted ona reciprocating valve.

The output of the Hall sensor provides the position feedback signal to the position control algorithm. The mag-netic assembly is environmentally sealed and is entirely external to the electronics housing. See Figure 2 - 2and Figure 2 - 6. The Hall effect sensor has a maximum travel range of up to 140 degrees rotation.

The position sensor also provides, through the electronics module, readout of valve position on the optionaldisplay and communication of valve position via HART protocol. The position transmission option provides a4-20 mA signal proportional to valve position transmitted on a separate pair of leads. A pair of contacts can sig-nal high and low position limits.Temperature SensorA temperature sensor is located in the electronics module and measures ambient temperature. This measure-ment is used to provide temperature compensation for the position and pressure sensors and other internalelectronic components. The temperature is read via the HART communication link to provide a warning ofexcessive ambient temperature at the positioner.Pressure Sensor OptionThe pressure sensor is located beneath the pneumatic module and measures the output pressure of the sin-gle acting relay. The pressure measurement is displayed on the local display or it is read by a HART commu-nication device. It is required for Advanced Diagnostics. Pneumatic ModuleThe pneumatic module consists of an assembly of the aluminum manifold, an intermediate sensors manifold,the I/P motor that converts a control current to a precision pressure, the pneumatic relay, and gages. The mod-ule is replaceable in the field. Its components can be serviced in a repair facility.

Current-to-Pressure Converter, I/PThe I/P converts a current signal to a pressure signal in the following manner. A fixed coil creates a magneticfield proportional to the applied current. The field magnetically pulls a flapper towards a nozzle to restrict air-flow through the nozzle. The backpressure in the restricted nozzle increases in response to an increase in thecoil current. Encapsulation of the coil provides protection from the environment. The I/P converts the controlcurrent to pressure that is amplified by the relay. Removing electrical power from the I/P always causes theoutput pressure to drop to its lowest value. This defines the startup and fail-safe characteristics of the SVI II.The I/P includes a removable subassembly, the flow regulator.

The flow regulator controls the airflow to the I/P accurately and independently of the air supply pressure. Thisenables the SVI II to operate over a wide range of supply pressures. The flow regulator includes a pair of finalair filters that block particles from reaching the nozzle from all sources. If excessive contaminated air reachesthe I/P the filters become restricted before the nozzle causing the I/P to go to the failsafe condition.

7 - 3


Single Acting Pneumatic RelayThe single acting pneumatic relay amplifies the pressure from the I/P and increases airflow as required for sta-ble, responsive, actuator performance. It is provided with a replaceable air filter that protects the I/P from par-ticulate contaminant's in the air supply. The relay is supply pressure compensated and operates on any sup-ply pressure that is at least 5 psi above the required actuator pressure, up to 150 PSI.Double Acting Pneumatic RelayThe double acting pneumatic relay amplifies the pressure from the I/P and provides a pair of high flow pres-sure output signals for operating a double acting cylinder actuator. It has a replaceable air filter that protectsthe I/P from particulate contaminants in the air supply. The relay operates on any supply pressure that is atleast 5 psi above the required actuator pressure, up to 150 PSIG. The two output pressures may be balancedby means of an adjustable seat assembly. The average of the two pressures is adjusted to equal roughly 70%of the supply pressure. The double acting relay is rated for supply pressure to 150 PSIG.

Supply Pressure BalanceAfter installation on the actuator, set supply pressure in accordance with actuator specifications. Do not exceedthe maximum pressure rating of the actuator. The seat is adjusted at the factory and set to 70% of supply pres-sure. If adjustment is required consult the factory. Optional Display and PushbuttonsThe optional display and buttons are mounted on the SVI II cover plate. The three pushbutton switches oper-ating in conjunction with the display permit reading and modification of the instrument operating parameterswithout a PC or HART hand-held communicator. These switches perform generic functions - Increase,Decrease, and Accept by movement through a conventional menu structure, see Chapter 3. The switches areoperated in a hazardous environment without compromising the flameproof enclosure.

Internal DiagnosticsThe SVI II performs internal self-diagnostics and hardware checks. When ValVue 2 or HART Handheld or thelocal display indicates that there are error messages write them down for troubleshooting. FAILSAFE Mode Several of the internal diagnostics tests puts the SVI II into FAILSAFE mode if the errors continue for a presettime. See Table 4 - 2. When the SVI II goes into FAILSAFE, the valve will be driven to its Failsafe position. Itremains in that position until a technician clears the cause of the error and resets the instrument. Reset is per-formed in two ways. Connect a HART modem and ValVue 2, and then click on the RESET button or turn thepower off and on.

To prevent the valve from moving after reset, put the controller in manual, and set the valve position setpointto the failsafe position 0% if ATO, 100% if ATC. The user can set a special case of FAILSAFE. The user mayset a Position Error Band and a Position Error Time 2 that forces the valve to its failsafe position if the positionerror exceeds the band for a time longer than time 2. This can be used on critical loops to force the processto trip if the positioner is unable to control the valve.Upgrading FirmwareThe SVI II is equipped with a nonvolatile re-writable Flash Memory for program storage. The firmware can beupdated as improvements and advances are made in the embedded programs that operate the SVI II.Firmware improvements for the SVI II can be obtained by contacting the factory.Tools Required:

HART modem

IBM PC with Windows, 95,98, NT 4.0, 2000 or later

ValVue 2 software or later (provided with software upgrade on CD-ROM)

Installing Firmware UpgradeIt is recommended that the configuration is uploaded and saved prior to the installation procedure. Follow theValVue 2 instructions to save the old configuration. Follow the detailed instructions included with the softwareupdate.To check the firmware version cycle the power off for 1 minute, then on, to perform a cold start. The displayshows software version in upper right corner. When maintenance is complete reinstall the positioner and per-form the checkout procedure detailed in chapter 3. Consult the factory for firmware upgrade services. ValVue2 is the recommended tool for complete reconfiguration. See Chapter 4.Single Action Relay

Check that all screws are tight.

Connect to a 30 psi supply pressure source.

Install a test gauge in the test point.

Disconnect the I/P connector from the electronics module.

Connect a current source to the inputs leads, + to red and – to back using .020 inch (0.5 mm)diameter probes.

Slowly raise the current until the relay output rises to about 1 psi.

Note the current (lift-off current) and the test point pressure (lift-off input pressure) NEVERexceed 1.6 mA. Permanent damage to the I/P motor can occur.

Continue to raise the current until output reaches 28 psi.

Note the current.

Check that relay output pressure lifts off to 1 psi or higher at test point pressure of about 9.5psi.

Raise the I/P current until the test point pressure is 5 psi higher than the lift-off input pressure.

7 - 11


Ground Faults at Main Input TerminalsWith an ohmmeter and with the input wires disconnected from the terminals, measure resistance from eachterminal to the case. There should be an open circuit or more than 1 MegOhm. Repeat the test with the wiresconnected. With the wires both connected to, and also disconnected from the terminals, measure resistanceto the cable shield. There should be an open circuit or more than 1 MegOhm. This procedure should be per-formed by personnel with adequate training on hazardous area instrumentation.

Test that 28 psi output occurs for approximately 5 psi above lift-off input pressure.

It is normal for the current to vary if the test is repeated.

Test may be repeated with higher supply pressure if the actuator requires higher pressure. At60 psi, the test pressure should be approximately 10 psi above lift off. At any rated supply, 1.6mA into the I/P should produce full supply at output.

Remove the dust cover from supply seat S/A.

Visually inspect that the piston in the supply seat S/A moves when output is exercised fully.

Reinstall the dust cover.

I/P Resistance Check

Disconnect the I/P connector from the electronics module.

Measure the resistance in both directions red to black and black to red.

Record the higher resistance that is measured. The nominal resistance is 1.4 KOhms. Normalvariation of 10% is expected. Lower resistance may indicate internally shorted turns.

Appendix D - Action ofAir to Open and AIr to

Close Actuators

It is important to correctly assignthe sign + or - of each control vari-able throughout a control system.Even the control valve subsystemcan be complex. Figure F - 1 andFigure F - 2 show the action of airto open, ATO, and air to close,ATC, valves when used with SVI II.The figures show a direct actingpositioner with linear and percent-age characteristics. Some hystere-sis is shown the actuator pressuresignal because of friction in typicalactuators. The scales are chosento emphasize the relationshipsbetween input current and actuatorpressure, so that the failsafe valveposition is shown at the lower leftof each graph. Note that for anATC valve, 4 mA represents 100%valve travel not the expected 0%.The controller and other humanmachine interfaces must correctlyshow that the valve is open 100%at 4 mA and closed 0% at 20. Thegraph shows the valve movementand actuator pressure when theTight Shut-off, T.S., option is set atabout 5%, in this example. Thevalve movement and actuatorpressure are also shown at the lowcurrent “lift-off” point at about 3.6mA, below which the positioner isinitializing its settings until power isstabilized.

A high quality air supply will greatly improve the quality of control and reduce maintenance costs of pneumat-ic equipment. See ANSI/ISA-7.0.01-1996 - Quality Standard for Instrument Air. Air supply failure requires spe-cial attention to minimize process effects. All process equipment should be designed and applied to fail to asafe condition. This includes failure of the air supply. SVI II is designed to fail to a condition of low or no airpressure. Control valve actuators should be chosen to move the valve to a safe condition when air pressureis low or absent. For example, a valve supplying fuel to a combustion process is normally equipped with anAir to Open valve. In other words, the fuel flow is shut off if air fails.

Additional process precautions can be taken. When the air supply recovers, the setpoint to the valve must beat a value that will continue to hold the valve in its safe condition, or to move it to a known safe condition. Todo so the control system sending the control valve position setpoint should be put into manual mode and setto 0%. After air supply has stabilized at its correct pressure then the setpoint can be move its operation pointin accordance with the plant’s safe start-up procedures. An additional precaution required on critical process-es with an ATO control valve is to install a shut-off valve that supplements the control valve by moving to asafe condition on air failure, and remains in that condition until all necessary requirements for safe start-uphave been met.

Appendix E - Air Supply Requirements

Keep clear of moving parts. The SVI II can cause the valve to move when the air supply returns.

Appendix F - Adjusting Speed of ResponseAUTOtune provides robust tuning parameters designed to tolerate variations in process characteristics. Youcan adjust the speed of response of the control valve by adjusting parameters in SVI II. Tuning parameters areadjusted by ValVue 2, the preferred method, or by the HHC 275. See the ValVue 2 manual.

Table G - 1 Tight Shutoff Parameters for High Pressure Liquid Letdown Trim

Tight shutoff Application to High Pressure Liquid Letdown Valve TrimWhen staged trim is used in High Pressure Liquid Letdown Valves, Tight Shutoff can be adjusted to move thevalve from the seat to begin throttling at the minimum operable Cv level. Using the tight shut-off feature in SVIII will prevent valve seat damage that may occur when throttling at clearance flows. See recommended TightShutoff settings in the following table. Tight shutoff may be adjusted with pushbuttons or with ValVue 2 or aHART communicator.

Using ValVue 2 Diagnostics with SVI IISVI II advanced features are simple to use with ValVue 2 software. The following examples illustrate someuses.Continuous DiagnosticsSVI II continuously gathers critical information that may be used to predict maintenance intervals forcontrol valves. These are:

Total Travel

Number of cycles

Time open

Time closed

Time near closed

Appendix G - Advanced Usage

Technology to Maximize Savings and Process Performance

This section shows examples of techniques for achieving superior process results by using ValVue 2 with SVIII to simplify maintenance and to achieve the benefits of SVI II’s advanced diagnostics capabilities. It will beassumed that the user is using HART communications with a modem and ValVue 2. Refer to the ValVue 2 UserGuide for complete instructions on these and other procedures.Tight Shutoff Application to Protect from Seat ErosionThe Tight shutoff feature can be programmed to prevent valve seat erosion using the full actuator force to elim-inate damaging leakage. At a position setpoint of 2%, for example, this function allows full thrust to occur whenthe input signal is less than 2%. This solves a common cause of valve repair. Do not use tight shutoff if it isnecessary to throttle the valve at very small flows.

A - 9

Monitoring a Valve Bellows SealThe SVI II automatically stores the accumulated valve stroke reversals, as Number of cycles. ValVue 2 can beused to periodically retrieve the values and to track the remaining life of a bellows seal or packing. Total trav-el may also be used to estimate the remaining life of packings and seals.Critical Service, Cavitation Control TrimThe time near closed, of a valve with severe service when near the seat, can be monitored by ValVue 2 andsaved to permanent files to monitor and predict maintenance needs. The user may use ValVue 2 to specifythe criterion for time-spent-near-closed (a valve position such as 4%, for example). See also Tight shutoff-Application to High Pressure Liquid Letdown Valve Trim.Diagnostic Valve TestsThe standard diagnostic test performs a full stroke test, and determines stroking speed. The Step Responsetest moves the valve between several points selected by the user and graphically presents the dynamicresponse for each step. The Positioner Signature test strokes the valve over a travel specified by the user andrecords a signature for comparison with the as-built and with future tests to predict maintenance intervals. Thefull version of ValVue 2 is required for diagnostic tests.

Accuracy - In a control valve the position is measured between mechanical motion limits in the valve.These limits can include position variations due to actuator and valve rigidity. therefore, accuracy isreferenced to positions within normal travel of the valve independent of rigidity effects at the mechan-ical limits. Accuracy is the greatest deviation from the expected position within the normal travel,expressed as percent of normal travel.

Actuator Type - The HART Communications Foundation classifies a positioner as type Actuator. Thismeans that it receives a 4-20 mA control current signal and causes an actuation function. A device oftype Actuator may not be connected to a circuit intended for a device of type Transmitter.

Algorithm - A set of rules that control the operation of an object through software. The SVI II positioncontrol algorithm is a modified PID. Other algorithms embedded in SVI II include the STOPS methodfor calibrating stroke, and the autoTUNE method for establishing the best parameters for the PID algo-rithm.

ATC Air to Close - The combination of a single acting actuator and the control valve where the valveis closed when air pressure is applied to the actuator

ATO Air to Open - The combination of a single acting actuator and the control valve where the valveis open when air pressure is applied to the actuator

CALIBrate - A mode of the positioner in which the user has access to changing the calibration ofstroke, input signal, and tuning parameters.

Characteristic - The positioner input setpoint command can be selectively modified to provide adesired relationship between setpoint and valve position. In the valve, the relationship between strokeand Cv is also called valve inherent characteristic. It is often adjusted by design, to equal percentage,for example. The positioner characteristic is applied to modify the setpoint to travel relationship of theactuator. The characteristic of the positioner must be chosen to compliment the valve. If the valve isequal percentage, the positioner should be set to linear. If a linear valve is installed the positioner canbe set to an equal percentage characteristic to improve flow control. SVI II offers an eleven point cus-tom characteristic option that can be created and edited in ValVue 2. Local display can be used toselect the custom characteristic, but cannot adjust the points.

Closed - The valve position in which the flow is minimum or zero. See tight shutoff.

Compliance Voltage - The voltage that must be available at the control system output in order to drivethe control current through the SVI II and all the resistive devices in series with it.

Conformity - The closeness to which the position approaches the theoretical position curve, for exam-ple equal percentage or quick opening. It is independent of effects due to valve or actuator rigidity atthe mechanical limits of travel. See Accuracy.

Compliance, HART - Manufactured and tested in accordance with the HART CommunicationsFoundation standards.

Condition Monitoring - A technology for measuring the performance of process equipment andvalves over a period of time to predict the need for maintenance. The technology evolved to meet NRCrequirements GL 89-10, and has proven valuable to other process industries. SVI II and ValVue 2 offera suite of diagnostic tools to implement condition monitoring.

Appendix I - Glossary

A - 12

CONFIGure - A mode of the positioner where the user has access to changing permanent parame-ters required for position control or for communications.

Custom (See Characteristic) - The custom characteristic in the SVI II has ten points to define therelationship between the setpoint and the valve position. The pushbuttons allow selection of the cus-tom characteristic that must be downloaded as pairs of data using the HART communications from aHART master. ValVue 2 offers a graphical drag-and-drop method to define the characteristic. Itincludes a method to correct for geometric non-linearity of the positioner feedback linkage.

DCS - Distributed Control System is a generic term for the common control system architecture thatgenerally performs process control in networked computers and interacts with field devices throughrack mounted I/O cards. A positioner is usually connected to a DCS output card which controls the 4-20mA current to the positioner.

Device Description, DD - The software object installed in the HART Handheld CommunicatorHHC275 to allow it to communicate and display the custom parameters available in a field device.

Diagnostics - The suite of software, and hardware tools that allow an SVI II to monitors its own inter-nal condition and to monitor the performance of the control valve and actuator system. Depending onoptions purchased the diagnostics can evaluate number of valve strokes, total accumulated valvestem travel, step response times with graphs, input to position relationships. Often system perform-ance signatures are obtained and retained to compare as-built with future performance to predictremaining useful service life.

Double Acting - An actuator is double acting when a piston is used that has pressure applied to bothsides of the piston. Typically used with a positioner that has two pressure outputs one that increasesand one that decreases with increasing position setpoint. The SVI II positioner must be configured tobe single acting or double acting as required for its actuator application. Configuration can be viaHART or via pushbuttons.

EEPROM - An Electrically Erasable Programmable Read Only Memory. SVI II has two memories thatare used for permanent storage of data that changes during operation. The micro-controller has EEP-ROM which permanently stores changing information such as number of actuator cycles and totalizedvalve travel. The program is stored in flash memory and can be upgraded.

Equal Percentage - A valve characteristicdesigned to compensate for the loss ofpressure in a pipeline as a control valve isopened. It is intended to linearize theinstalled flow versus lift characteristic forimproved control. *The theoretical curve isy= a*e x*ln(1/a) , where a is .02, 1/R, andR=50 for a 50:1 equal percentage charac-teristic. However, the theoretical curveleaves the valve unseated by 2% at 0%input. The actual curve, shown here, iscorrected to seat the valve at 0%. Thecorrected curve is Y=(a*e x*ln(1/a) -a)/(1-a).

Error Messages - The positioner stores the reasons for errors. The error messages can be read byHART or with the local display.

Fail Safe - A mode of the positioner where the valve position is controlled to a predetermined safeposition. This mode is forced by the positioner program in response to errors. If the errors are clearedthen RESET returns the positioner to the mode prior to the error.

Fatal Error - An error which the SVI II program treats as non-recoverable. Service is required.

Flash Memory - A computer memory that is not volatile. It stores all its data even when the power isoff. It performs high speed reads and can be re-written many times. It is used to store programs andpermanent parameters.

FSK - Frequency Shift Keying see HART protocol.

Hall Effect Sensor - A semiconductor magnetic-field sensor that measures the magnetic flux perpen-dicular to the sensor.

HART - HART is an acronym for Highway Addressable Remote Transducer. The HART protocolmakes use of the Bell 202 Frequency Shift Keying (FSK) standard to superimpose digital signals at alow level on top of the 4-20mA. This enables two-way communication to take place and makes it pos-sible for additional information beyond just the normal process variable to be communicated to/from asmart field instrument. The HART protocol communicates without interrupting the 4-20mA signal andallows a host application (master) to get two or more digital updates per second from a field device.As the digital FSK signal is phase continuous, there is no interference with the 4-20mA signal.

HART Communication Foundation - The HART Communication Foundation is an independent, non-profit corporation specifically organized to coordinate and support the application of HART technologyworldwide. Educating the industry on the capabilities and value of this important technology is a keyrole. Operating costs are offset by membership and training/support service fees. Membership is opento all suppliers, end users, and others interested in the use of HART technology.

HART Filter - A filter required with certain DCS systems that are not HART compliant. It allows the 4-20 mA output signal to pass from control system to positioner, but blocks HART FSK tones from pass-ing from the field wiring to the control system.

HART Master - A device, usually a PC which is controlling the communications over a HART protocolnetwork. The HART master sends to a field device a command and requires a response.

HART Slave - A device, normally a transmitter or positioner, that communicates over a HART proto-col network only in response to a command from a master.

Hazardous Area - The area of the plant where explosion hazards are present, hazards such aspropane gas in a refinery, or dust in a flour mill.

HHT 275 - The HART Handheld Communicator supplied by Fisher-Rosemount. It supports the DD’sfor all field devices. The DD’s are combined into a single file and loaded into the HHC 275 memory bya manufacturer. Memory is available in several capacities.

A - 14

Hot Swapable - The SVI II in combination with ValVue 2 enables a very brief Mean Time To Repair bythe following process: Upload all configuration information from installed positioner to ValVue 2, thenreplace the positioner and download the configuration file. Run STOPS, and autoTUNE, and the repairis complete.

I/P Converter - The current to pressure converting device. The SVI II sends an analog current signalto the I/P which produces a controlled pressure to the pneumatic amplifying relay.

ISA - The Instrument Society of America. ISA develops and publishes international standards for usein process control. See www.isi.org.

Multidrop - A variation of the HART Communications Protocol that allows many smart field devices todraw power from and to communicate over a single pair of wires. Though most suited to multiplemeasurement devices, it can be used with SVI II to permit digital communication of setpoint as well asconfiguration data, to multiple positioners or a combination of positioners and measurement transmit-ters. Such communication may not be fast enough for flow control.

Multiplexer - Several instrument suppliers offer equipment that can be connected to multiple cablesto monitor and communicate with the attached positioners and transmitters using the HART protocol.Often the multiplexer is used with a DCS that does not support HART.

NAMUR - NAMUR is a European user association of process control technology in chemical and phar-maceutical industries. “Recommendations and Worksheets are experience reports and working docu-ments prepared by NAMUR for its members among process control users for facultativeutilization”.NAMUR issued a recommended accessory mounting for control valves (NE 14 AnschlußvonSchwenkantrieben an Armaturen 06.08.96) which describes a method for mounting a positioner on anactuator. See at www.namur.de.

Neodymium Iron Boron - A magnet alloy which provides the highest energy magnetism available ina permanent magnet.

Non-Volatile Memory - Computer memory that is not lost when power is turned off. Used to perma-nently store calibration, configuration and diagnostic information in SVI II.

Normal OPERating Mode - The control mode for normal use of a valve positioner. The positionerreceives a setpoint from a controller or DCS and applies pressure to the actuator to move the valve tothe required position.

OPERate - Operate is displayed when the positioner is in Normal OPERating mode.

PC - As used in this manual, a personal computer or laptop running under Windows 95 or later oper-ating system.

Position - With a reciprocating valve, the position is the distance of the plug from its seat, normallymeasured as a linear motion of the valve or actuator stem. With a rotary valve the position is the angleof rotation of the valve plug measured as angular rotation of the valve shaft.

Position Limit - The Actuator can be mechanically set to stop at a predetermined position by settingan adjustment, sometimes with a handwheel or screw stop. SVI II can be configured to provide thesame limits through software control of position.

Positioner Tuning Parameters - The positioner requires six integer parameters to determine theresponse of the positioner to a setpoint change. Internally, the positioner uses an improved PID con-trol algorithm to control the valve’s position.

A - 15

Tuning Parameters

P - P is a dimensionless gain factor related to the proportioning action of the algorithm. Itranges from0 to 5000. Common values for the positioner are 50 for small valves up to 4000 for largevalves.

I - (0.1 sec): Integral time or reset time, is the time constant of integral control. Higher valuesof I cause slower integral action. Common values are 10 (1 second) to 200 (20 seconds). Avalue of zero disables integral action.

D - (msec): Derivative time or rate time is the time constant of derivative control expressed inmilliseconds. It ranges from 0 to 200 msec. Common values are 0 to 100. A value of zero dis-ables derivative action.

Beta - Beta is a nonlinear dimensionless gain factor, ranging from -9 to 9. When beta is 0, thecontroller gain is linear. Otherwise the gain is the function of error. The larger the beta, thesmaller the gain for small error. Typical beta values for a valve position controller are between–9 and 0.

Padj (%) - Valves often have significantly different response when filling versus exhausting.The proportional gain is adjusted by adding Padj to P when the valve is exhausting. Padj isnormally less than P.

Position Compensation Coefficient - The response of the valve is different when the valveis nearly closed than when the valve is nearly open. The position compensation coefficient,which is a number between 0 and 9, allow the control algorithm to optimize the valveresponse.

Damping Coefficient: - The valve response may be made slower for some applications. Avalue of 0 gives no damping, and a value of 9 gives maximum damping of valve motion.

Dead Zone(%): - When the valve position is within the setpoint +/- the dead zone, no addi-tional position control is performed. This value is normally 0%, however for high friction valves(e.g. valves with graphite packing) a higher dead zone will help avoid limit cycling due to thestick/slip action of the valve. In these cases the dead zone chosen might be 0.2% to 1%.

Quick Opening - see Characteristic)

Relay, Pneumatic - The component that amplifies the pneumatic control signals to provide a widerange of actuation pressure and to supply and vent at high flow rates for responsive control.

Safe Area - The area of a plant where there never is an explosion hazard present, such as the con-trol room or a wire marshalling rack area.

Sig Hi - In the SVI II configuration, the input current setting at which the valve is fully open (ATO) orfully closed (ATC)

Sig Lo - In the SVI II configuration, the input current setting at which the valve is fully closed (ATO) orfully open (ATC)

Single Acting - The action of a position with a single pneumatic output for operation with a springreturn actuator. (see double acting).

A - 16

Split Range - A control configuration where a single control output is sent to two or more controlvalves. Each control valve positioner is calibrated to respond to a separate portion of the control sig-nal. An example is a steam valve and a cooling water valve arranged to be both closed at 50% andthe steam valve to open.

STOPS - The SVI II runs STOPS procedure to adjust the positioner to actual valve travel. First the out-put pressure is reduced to zero and the position is recorded. That will be the position correspondingto 0%. The output pressure is raised to its maximum based on supply pressure. The position is record-ed and corresponds to 100%.

Stroke - The total range of valve travel. Often used as a verb to describe the process of moving thevalve.

Tag - The formal designator the control valve used in control loop documentation.

Tight Shutoff (TS) - A positioner property which is selected and adjusted when it is desired to preventoperation of the valve at or near the closed position. The positioner will cause all available actuatorforce to be applied to the valve seat at a position set point equal to or less than the TS adjustableparameter. A dead band is applied to prevent cycling in and out of this behavior.

ValVue® 2.0 Lite - The Masoneilan software for calibration, and configuration that is provided withevery SVI II.

ValVue® 2.0 - The full featured Masoneilan software for diagnostics, calibration, and configuration ofSVI and SVI II.

VDE/VDI 3845 - A Standard common in Europe for mounting positioners and accessories on rotaryvalve actuators.

Warning!: Always isolate the control valve from the process before performing the following checkout procedure.

3 - 4

Caution!: Use of a low impedance voltage source will damage the SVI II. The current source mustbe a true high impedance current limiting device. A proper current source will explicitly enableadjustment of the current in mA (NOT volts).

3 - 5

Note: When an SVI is turned on, it is advisable to apply the air supply before applying the electricalinput signal.

3 - 4

Note: If the SVI II is specified without local pushbuttons and display, local operation is not available.Configure and calibrate with ValVue 2 Lite and a HART modem.

3 - 5

Warning!: This operation will cause the valve to move. Before proceeding further, be sure that thevalve is isolated from the process.

3 - 5

Note: You must return the mode to 3 - 7Note: Setting the input current span (Range tab) is normally unnecessary, except for applicationssuch as split ranging. In addition, note that calibration of the input current sensor (Sig Cal tab)requires the use of high accuracy current standards. The factory settings should only be changed ifa calibration laboratory detects errors.

3 - 11

Note: Never connect ValVue 2 to an SVI II that is in configuration or calibration using pushbuttons. 3 - 11

Warning: Cover and housing surface must be clean and flat. Tighten all four cover screws. 3 - 11

Note: If the buttons are pushed after being locked by the ValVue software, the message 4 - 1

Note: The characteristic configured in the positioner is applied in addition to the plug characteristic 4 - 3

Note: Always perform configuration before running calibration functions. 4 - 9

Warning!: The valve must be isolated from the process before starting calibration. Calibration func-tions stroke the valve over its full range.
