Introduction

Scope of Manual

This manual provides installation, startup,calibration, maintenance, and parts orderinginformation for 2506 Series Multi-Trol�receiver/controllers. Figure 1 shows a Type 2506receiver/controller. Figure 2 shows a Type 2516receiver/controller.

A 2506 Series receiver/controller is often used with a2502 Series Level-Trol® controller/transmitter. Forinformation about 2502 Series controller/transmittersor associated equipment such as pressureregulators, sensors, accessories, or related controldevices, see the appropriate instruction manual, orcontact your Fisher® sales office.

No person may install, operate, or maintain a 2506Series Multi-Trol receiver/controller without first �being fully trained and qualified in valve, actuatorand accessory installation, operation andmaintenance and � carefully reading andunderstanding the contents of the manual. If youhave any questions about these instructions, contactyour Fisher sales office.

DescriptionSee table 2.

The receiver/controllers described in this manualprovide:

� Proportional-only control: Type 2506 (with snapaction: Type 2506S)

� Proportional-plus-reset control (Type 2516)

� Proportional-plus-reset-plus-anti-reset windupcontrol (Type 2516F)

See figures 9, 10, and 11.

The receiver/controller takes a pneumatic inputsignal from either a 2500 Seriescontroller/transmitter or a control device. The unitthen provides a pneumatic output signal thatoperates a final control element.

When a Type 2506 receiver/controller is used toprovide proportional-only control, the pneumaticoutput signal from the unit can also be piped to aremote receiving indicator or recording device. Thisprovides a visual indication of receiver/controlleraction.

The INCREASE OUTPUT PRESSURE adjustment isused to increase or decrease the output pressure inrelationship to the input pressure. Changing thisadjustment changes the position of the nozzle inrelationship to the beam/flapper assembly. In turn,the amount of supply pressure released by the relayis changed and the pneumatic output signal thatoperates a final control element is affected.

If a remote set point signal is used, it is piped to theremote set point connection and into remote setpoint bellows. The remote signal expands thebellows and moves the beam/flapper assembly. Thisaffects the controller output in the same way achange in the INCREASE OUTPUT PRESSUREadjustment affects the output.

Connections

WARNING

The controller is capable of providingfull supply pressure to connectedequipment. To avoid personal injury orproperty damage caused by partsbursting from system overpressure,make sure the supply pressure never

exceeds the maximum safe workingpressure of any connected equipment.

To complete the installation of a receiver/controller,make connections with tubing and fittings betweenthe receiver/controller and the actuator. The fittings,tubing, and mounting parts required depend on thetype number and optional equipment such as filter,regulator, and bypass valve.

All pressure connections on the 2506 Seriesreceiver/controllers are 1/4-inch NPT female fittings(figures 3 and 9). Use 1/4-inch piping or 3/8-inchtubing to these connections.

If remote venting is required, see the Ventssubsection below.

If the existing supply is corrosive,make sure the tubing and instrumentcomponents that contact the corrosivemedium are of suitablecorrosion-resistant materials, orchange to a noncorrosive supplymedium.

WARNING

Personal injury or property damagemay occur from bursting parts due tooverpressuring any systemcomponent. To avoid injury or

damage, provide pressure-relieving orpressure-limiting devices if supply orinput pressure could exceed themaximum allowable pressures listed intable 3.

It is recommended that supply pressure passthrough a filter/regulator combination such as a67CFR. See table 3 for recommended supplypressures to the receiver/controller.

Typical supply pressure for the 67CFR is clean dryair or a gas at a pressure of 2.5 bar (35 psig) to amaximum of 17 bar (250 psig). For specific regulatorlimits, see the appropriate regulator instructionmanual.

Output ConnectionsSee figure 3.

Use 3/8-inch tubing between the actuator and thereceiver/controller. Connect the output (diaphragm)connection to the appropriate actuator connection.

Vents

WARNING

If a flammable or hazardous gas isused as supply pressure medium,personal injury or property damagecould result from fire or explosioncaused by the accumulated gas. Injuryor property damage could also result

from contact with the flammable orhazardous gas.

The case and cover assembly does notform a gas-tight seal and flammable orhazardous gas could leak from thisunit. Therefore, if thereceiver/controller unit is enclosed,install a remote vent line to removepart of the exhaust gas to a properlyventilated area. However, a remotevent line cannot be relied upon toremove all hazardous gas. Vent linepiping should comply with local andregional codes and should be as shortas possible. Select vent line pipingwith adequate inside diameter andinstall with few bends to reduce casepressure buildup.

See figure 3 for vent locations.

A receiver/controller may be ordered with one of twovent configurations:

� Standard, with 1/4-inch case vent open. Thestandard receiver/controller case (key 1, p/n 4D396044012) is not drilled and tapped for theoptional tapped vent.

� Optional, with tapped vent, for applicationsrequiring vent line attachment to receiver/controllercase. The optional receiver/controller case (key 1,p/n 2E355544012) features a tapped vent forapplications requiring a remote vent line. Thestandard case vent should be sealed with a machinescrew.

An air vent plug (key 137) with gasket (key 138) andhex nut (key 139) can be added to the tapped vent.The air vent plug provides a 1/4-Inch NPT femalefitting.

� Receiver/controllers feature an open bellowsvent/remote set point connection. An external ventassembly (key 128) is recommended if the remoteset point connection is not made. The external ventassembly can be driven into the open bellows vent.

Protect all vents against the entrance of any foreignmaterial that could plug them. Check the ventsperiodically to be certain they are not plugged.

Remote Set Point Connection

WARNING

Severe personal injury or propertydamage may occur if the instrumentair supply is not clean, dry and oil freeor non-corrosive gas. While use andregular maintenance of a filter thatremove particles larger than 40microns in diameter will suffice inmost applications, check with a FisherField office and Industry Instrument airquality standards for use withcorrosive gas or if you are unsureabout the proper amount or method ofair filtration or filter maintenance.

See figure 3.

The remote set point connection is made at thetapped bellows vent/remote set point connection onthe rear of the receiver/controller case. A ventassembly (key 128) is recommended if the remoteset point connection is not made.

To make a remote set point connection, remove thevent assembly from the connection. Install pipingfrom the remote set point loader or regulator.

When a panel loader or regulator is used for remoteset point adjustment, as shown in figure 11, anadjustable output range of 0.2 to 1 bar (3 to 15 psig)or 0.4 to 2 bar (6 to 30) is required to match thereceiver/controller output range.

Use clean, dry air or a non-corrosive gas for supplypressure to the remote set point bellows.

StartupIt is important that the output range of the transmitteror other device used as the input to thereceiver/controller be adjusted so that its outputrange corresponds to the input signal range of thereceiver/controller. Be sure the receiver/controlleraction (direct or reverse) is correct for theapplication.

To start the system:

� For all receiver/controllers, perform steps 1and 2.

1. See table 3 for specific pressure limits. Be surethe correct supply pressure is available. Ifnecessary, adjust the regulator to 1.4 bar (20 psig)for a 0.2 to 1 bar (3 to 15 psig) or 2.4 bar (35 psig)for a 0.4 to 2 bar (6 to 30 psig) receiver/controllerrange.

2. Turn on the supply pressure to thereceiver/controller.

� To make the proper level or output pressuresetting for a Type 2506 receiver/controller, go tostep 3. To make the proper level or outputpressure setting for a Type 2516receiver/controller, go to step 9.

� For the Type 2506 receiver/controller:

3. Set the proportional band adjustment at 15percent (1.5 on the adjustment dial). At this setting, a0.1 bar (1.8 psig) input pressure causes a 12 psig



12

output pressure change. Operate thereceiver/controller with the proportional band settingas small as possible.

4. Provide an input pressure equal to the outputpressure of the transmitter at a value desired orhalfway between the transmitter output range. Forexample, on a receiver/controller, if the desiredcontrol point is halfway between the ends of thedisplacer, provide an input of 0.6 bar (9 psig) whichis halfway between 0.2 and 1 bar (3 and 15 psig)transmitter output range.

5. Set the output pressure adjustment to give acontroller output that is halfway between its outputrange.

6. Vary the input pressure to be sure the fullcontroller output pressure range is produced withinthe specified input pressure range.

7. Lock the output pressure adjustment and connectthe receiver/controller to the final control element.

8. If the proportional band setting is too narrow,causing instability, widen the proportional band justenough to stabilize control. After making thisadjustment, it may be necessary to reset the outputpressure slightly to produce the proper controlrange.

� For the Type 2516 receiver/controller:

9. Set the proportional band adjustment dial at 0percent (minimum proportional band).

10. Set the reset adjustment to the fastest speed(0.005 minutes-per-repeat).

11. Provide an input pressure equal to the outputpressure of the transmitter at a value desired orhalfway between the transmitter output range. Forexample, on a receiver/controller, if the desiredcontrol point is halfway between the ends of thedisplacer, provide an input of 0.6 bar (9 psig) whichis halfway between 0.2 and 1 bar (3 and 15 psig)transmitter output range.

12. Adjust the output pressure dial to give acontroller output somewhere within the output rangeof the receiver/controller.

13. Lock the output pressure dial and connect to thefinal control element.

14. If the proportional band is too narrow causinginstability, widen the proportional band or slow thereset just enough to stabilize control.

AdjustmentsTo adjust the receiver/controller, open the cover andlocate the appropriate adjustment. See figures 14,15, and 16 for the location of adjustments.

Set Point AdjustmentTo adjust the level set point, loosen the knurled knoband rotate the knob around the INCREASEOUTPUT PRESSURE or RAISE LEVEL dial. Toraise fluid or interface level or increase density,rotate the knob in the direction of the arrow.

To lower level or decrease density, rotate the knobin the opposite direction. The INCREASE OUTPUTPRESSURE or RAISE LEVEL dial is graduated (inpercent) to show approximate indications of thereceiver/controller set point. When makingadjustments, do not rely only on the dial setting.Monitor the process fluid level to be sure thereceiver/controller attains the desired set point.

For differential gap receiver/controllers, the levelsetting adjustment determines the location of thegap within the range of the sensing element.

Remote Set Point AdjustmentOn a receiver/controller with remote set pointadjustment capability, adjust the set point bychanging the pressure to the remote set pointconnection. Increase the remote set point signalpressure to decrease the receiver/controller set point(for a direct acting receiver/controller) or increasethe receiver/controller set point (for a reverse actingreceiver/controller).

Proportional Band AdjustmentFor proportional and proportional-plus-resetreceiver/controllers, the proportional bandadjustment determines the amount of change in theinput pressure required to change the controlleroutput signal from one limit of the output signalrange to the other limit (without the effect of resetaction).

Proportional band is expressed as a percent of thesensing element range. That is, with a proportionalband of 100 percent, an input pressure changeequal to the sensing element span would change thecontroller output from one limit to the other. With aproportional band of 50 percent, an input pressurechange equal to one half the sensing element range


13

would change the controller output from one limit tothe other.

The proportional valve dial is graduated from 0 to 10.A setting of 10 on the dial represents a proportionalband of 100 percent; 5 represents a proportionalband of 50 percent.

The receiver/controller is designed for a maximumproportional band of 200 percent. The effective bandis determined by the location of the adjustablenozzle assembly (key 17, figure 14) in the slot in thelevel set arm (key 28). Most applications require amaximum band of 100 percent so, at the factory, areceiver/controller unit is set to the 100 percentvalue. This setting places the nozzle at a point that ishalfway between the bellows assemblies. To adjustthe proportional band, rotate the adjustmentcounterclockwise to broaden the setting. Rotate theadjustment clockwise to narrow the setting.

In some applications, a 200 percent proportionalband range may be required. To obtain the 200percent range, move the nozzle assembly to theextreme right end of the slot in the level set arm.

For differential gap receiver/controllers, theproportional band adjustment determines the widthof the differential gap. This is the difference betweenthe input pressures at which the controller outputswitches from zero to full supply pressure and backto zero.

Reset Adjustment (Type 2516 Receiver/Controller Only)On proportional-plus-reset receiver/controllers, thereset adjustment determines the time in minutesrequired for the reset action to produce a change inoutput pressure equal to the change that hasoccurred due to proportional band action.

To adjust the reset action, rotate the adjustmentclockwise to decrease, or counterclockwise toincrease the minutes per repeat. Increasing theminutes per repeat provides a slower reset action.

Anti-Reset Windup Valve Adjustment (Type 2516F Receiver/Controller Only)The anti-reset windup valve provides differentialpressure relief. Its adjustment control extends fromthe back of the receiver/controller case (figure 16).

The factory sets this valve to relieve when thedifferential pressure between the proportional andreset bellows reaches 5 psi. To set the valve torelieve when the differential pressure is as low as 2psig, turn the adjustment screw clockwise. To set thevalve to relieve when the differential pressure is ashigh as 7 psig, turn the adjustment screwcounterclockwise. The minimum differential settingyields the minimum differential set point overshootduring startup.

Depending on the characteristics of the process, theanti-reset windup valve can be positioned so that thearrow on the case points to the letters RE or, to theletter P on the back of the manifold. If the arrowpoints to P, the valve opens when receiver/controlleroutput pressure rises. If the arrow points to RE, thevalve opens when receiver/controller outputpressure falls.

Calibration

WARNING

The following calibration proceduresrequire taking the controller out ofservice. To avoid personal injury andproperty damage caused by anuncontrolled process, provide sometemporary means of control for theprocess before taking thereceiver/controller out of service. Alsorefer to the Warning at the beginningof the Maintenance section.

See figure 14 for key number and adjustmentlocations.

When performing the following calibrationprocedures, open loop conditions must exist andmake provisions to monitor the output pressure. Oneway to obtain an open loop is to disconnect thecontroller output signal line and install a pressuregauge.

Note

When calibrating a combinedcontroller arrangement such as theType 2500 with the Type 2506 or 2516(figure 9), calibrate the Type 2500controller/transmitter first.



14

For a direct action receiver/controller:

1. Adjust the INCREASE OUTPUT PRESSUREadjustment to mid-range on the scale.

2. Turn the proportional band adjustment to 100percent of the scale range.

3. For Type 2516 only, turn the reset valveadjustment fully clockwise.

4. Adjust the input pressure to 0.6 bar (9 psig) for a0.2 to 1 bar (3 to 15 psig) or 1.2 bar (18 psig) for a0.4 to 2 bar (6 to 30 psig) receiver/controller.

5. For Type 2516 only, turn the reset valveadjustment fully counterclockwise (to the CLOSEDposition). This locks 0.6 bar (9 psig) or 1.2 bar (18psig) in the reset bellows.

6. If the output pressure is 0.6 bar (9 psig) for a 0.2to 1 bar (3 to 15 psig) or 1.2 bar (18 psig) for a 0.4 to2 bar (6 to 30 psig) receiver/controller, go to step 8.If not, continue with step 7.

7. If the output pressure span is too low, move thenozzle down towards the flapper, if output pressureis too high, move the nozzle up. Continue by trialand error until the desired setting is obtained.

8. Adjust the input pressure to 1 bar (15 psig) for a0.2 to 1 bar (3 to 15 psig) or 2 bar (30 psig) for a 0.4to 2 bar (6 to 30 psig) receiver/controller.

9. The output pressure should be 1 bar (15 psig) fora 0.2 to 1 bar (3 to 15 psig) or 2 bar (30 psig) for a0.4 to 2 bar (6 to 30 psig) receiver/controller. Ifoutput pressure is within application tolerance,proceed to step 12. If not, continue with step 10.

10. If the output pressure span is narrow, move thenozzle slightly to the left or, if the output pressurespan is too wide, move it to the right and repeatsteps 4 and 6 through 10.

11. Repeat the steps until the receiver/controller iswithin application requirements.

12. Reconnect the receiver/controller to the controlloop and see the Adjustment section.

Figure 12. Type 2506 Multi-Trol® Direct ActionReceiver/Controller Schematic

Principle of OperationThe 2506 Series uses a basic pressure balancerelay system (figure 12). The relay is connected sothat supply pressure is fed to the inlet side of therelay valve and the fixed restriction. From thisrestriction, the air pressure bleeds into the relaychamber on one side of the large diaphragm andalso to the nozzle. As long as there is no pressurechange on either diaphragm, the relay valve remainsin equilibrium with both inlet and exhaust endsclosed. The area ratio of the large diaphragm to thesmall diaphragm is 3 to 1. A 12 psi pressure changeon the small diaphragm is balanced by a 4 psichange in the large diaphragm.

The following descriptions show how the relay workswith the standard proportional,proportional-plus-reset, and proportional-plus-resetwith anti-reset windup receiver/controllers.

Type 2506 Receiver/Controllers

See figure 12.

As long as the process level remains constant, thetransmitter input pressure to the receiver/controllerremains constant. Inside the receiver/controller, thebellows beam/flapper assembly remains in asteady-state position.

The position of the bellows beam allows the supplypressure to bleed through the nozzle as fast as itenters the relay through the fixed restriction. Achange in transmitter input pressure repositions thebeam/flapper assembly with respect to the nozzle.

On a direct action receiver/controller, an increase intransmitter input pressure causes a pressureincrease in the sensing bellows assembly, tending topush the beam toward the nozzle. This restricts theescape of supply pressure through the nozzle, thusincreasing the pressure on the large diaphragm inthe relay. This opens the relay valve to the supplypressure allowing an increase in output pressure tothe control valve.

A decrease in transmitter input pressure decreasesthe pressure in the input bellows assembly bymoving the beam away from the nozzle. This allowsthe supply pressure to bleed through the nozzlefaster than it can enter through the fixed restriction inthe relay. The relay valve opens, exhausting theoutput pressure which vent through the relayexhaust port. This action decreases output pressureto the control valve.

Type 2516, 2516F Receiver/ControllersThe action of a proportional-plus-reset controller(figure 13) is similar to that of a proportionalcontroller except that feedback from the controlleroutput pressure is piped to a reset bellows as well asto the proportional bellows.

Users can adjust the reset valve on the Type 2516and 2516F to channel some or all of the proportionalpressure into the reset bellows that opposes theproportional bellows action. This arrangementautomatically reduces the effect of any proportionalovercorrection by a set amount per time interval, aslong as there is a deviation from the control point.



16

The Type 2516F receiver/controller also features ananti-reset windup valve. This valve providesdifferential pressure relief to prevent proportionalpressure from exceeding reset pressure by morethan a set value. The proportional valve outputpressure registers on one side of the diaphragmchamber and the reset valve output pressureregisters on the other side diaphragm. A suddenincrease in the output pressure causes a rapidpressure increase in the proportional bellows and inthe proportional side of the diaphragm chamber. Ifthe diaphragm pressure of the relief valve exceedsthat of the spring side by the amount of the reliefpressure setting, the relief diaphragm moves off theorifice in the differential relief valve. This allows thepressure on the proportional side of the diaphragmto bleed into the reset system. This action providesquick relief of excessive proportional pressure andreduces the time required by the system to return tothe control point. A user can reverse the differentialrelief action to relieve on decrease output pressure.

MaintenanceReceiver/controller parts are subject to normal wearand may require inspection or replacement. Thefrequency of inspection and parts replacementdepends upon the severity of the service conditions.When inspection or repairs are needed, disassembleonly those parts necessary to accomplish the job.

Select the appropriate maintenance procedures andperform the appropriate steps. Each procedurerequires that supply pressure and process pressurebe shut off before beginning maintenance.

Establish a maintenance cycle to regularly clean thevents (figure 3). Also, establish a maintenance cycleto clear the relay orifice (key 88, not shown) bypushing in the plunger of the core assembly (key89).

WARNING

The following maintenance proceduresrequire taking the controller out ofservice. To avoid personal injury andproperty damage caused by anuncontrolled process:

� Always wear protective clothing,gloves, and eyewear when performing

any maintenance operations to avoidpersonal injury.

� Provide some temporary meansof controlling the process beforetaking the receiver/controller out ofservice.

� Release any trapped pressurefrom the controller and vent supplypressure before disassembly.

� Check with your process or safetyengineer for any additional measuresthat must be taken to protect againstprocess media.

Changing Controller ActionSee figure 14 for key number locations, unlessotherwise directed.

Note

Do not switch the Type 2516receiver/controller to snap (S) action.

To change controller action, reposition one or bothswitch plates (key 132), which are mounted on theleft or right bellows assemblies (key 134 or 133respectively). When either switch plate (key 132) isremoved, the raised letters D, R, S, and P are visibleon the bellows frame located under the switch plate(figure 14).

These letters correspond to: direct (D), reverse (R),snap (S), and proportional (P) control action. Toobtain the type of control desired, position the switchplates so that the proper letter appears in the cut-outcorner, as explained below:

� The bellows assembly on the left provideseither direct or reverse action. Thereceiver/controller (Type 2506 or 2516) can bechanged between direct and reverse action byrepositioning the switch plate (key 132) on the left.Direct action (D) is when increasing transmitter inputpressure increases receiver/controller outputpressure. To obtain direct action, position the switchplate so the D is visible. Reverse action (R) is whendecreasing transmitter input pressure increasesreceiver/controller output pressure. To obtainreverse action, position the switch plate so the R isvisible.

� The bellows assembly on the right provideseither proportional (P) or snap (S) action depending


17

on the switch plate position. For all types ofreceiver/controllers, to obtain proportional action,position the switch plate so the P is visible. For Type2506 receiver/controllers, to obtain snap action,position the switch plate so the S is visible.

TroubleshootingAs an aid to troubleshooting, see table 4 for a listingof some common operating faults, their probablecause, and suggested procedures for correcting thefaults.

Testing Relay Deadband1. Replace the PROPORTIONAL BAND adjustmentassembly with a 1/8-inch NPT pipe plug according tothe sections for changing proportional, reset, oranti-reset windup valves.

2. Turn on the supply pressure and set it to 1.4 baror 2.4 bar (20 or 35 psig) according to supplypressure requirements of the receiver/controllers.

3. By changing the process variable and adjustingthe INCREASE OUTPUT PRESSURE control, setthe output pressure to 15 or 30 psig. Whilemonitoring the output pressure, slowly change theprocess until an output pressure change just begins.Record the value of the process variable at thisdetection point.

4. Change the process variable in the oppositedirection until another output pressure change justbegins. Again, record the value of the processvariable. If the difference between the two values(the deadband) is more than 0.2 percent of themaximum displacer length, the relay must berepaired or replaced.

5. See the relay removal and replacementprocedures and, if necessary, the relay disassemblyand assembly procedures if the relay is to berepaired.

6. Turn off the supply pressure, remove the pipeplug, and install the PROPORTIONAL BANDadjustment assembly.
