3 Design and principle ofoperation

The electropneumatic positioner is attachedto pneumatic control valves. It is used to as-sign the valve stem position (controlled vari-able x) to the control signal (reference vari-able w). The input signal received from acontrol system is compared to the travel orrotational angle of the control valve, and apneumatic signal pressure (output variabley) is produced.

The positioner basically consists of an elec-trical travel sensor system (2), an analog i/pconverter (6) with downstream air capacity

booster (7) and the electronic unit with amicrocontroller (5).

The standard positioner is fitted with threebinary contacts: A fault alarm output indi-cates a fault to a control station and twoconfigurable software limit switches areused to indicate the end positions of thevalve.

The position of the valve is transmitted aslinear travel motion or angle of rotation viapick-up lever and travel sensor (2) to an an-alog PD controller (3). Simultaneously, anA/D converter (4) transmits the position ofthe valve to the microcontroller (5). The PDcontroller compares this actual position to

the 4 to 20 mA DC control signal (referencevariable) after it has been converted by theA/D converter (4). In case of a system devi-ation, the actuator is either vented or filledwith more air. The supply air is supplied tothe air capacity booster (7) and the pressureregulator (8). An intermediate flow regulator(9) with fixed settings is used to purge thepositioner and also guarantees trouble-freeoperation of the air capacity booster. Theoutput signal pressure supplied by thebooster can be limited over the software.The volume restriction Q (10) is used to opti-mize the positioner by adapting it to the ac-tuator size.

The extended EXPERTplus diagnostics are in-tegrated into the positioner. It provides infor-mation on the positioner and generates di-agnostic and status alarms, which allowfaults to be pinpointed quickly.

The positioner is suitable for the followingtypes of attachment using the correspondingaccessories:

4 Direct attachment to SAMSONType 3277 Actuator: Section 4.1

4 Attachment to actuators acc. toIEC 60534-6 (NAMUR): Section 4.2

4 Attachment to Type 3510 Micro-flowValve: Section 4.4

4 Attachment to rotary actuators acc. toVDI/VDE 3845: Section 4.5

3.1 Additional equipment

Solenoid valve

If the operating voltage for the solenoidvalve (12) fails, the supply pressure for thebooster is vented to the atmosphere. Conse-quently, the actuator is vented and the valvemoves to the fail-safe position.

NOTICEIn manual mode (MAN), the manual setpoint is also reset to 0 %. A different manualset point must be entered again (Code 1).

Position transmitter

The position transmitter (13) is a two-wiretransmitter and issues the travel sensor sig-nal as a 4 to 20 mA signal processed by themicrocontroller. Since this signal is issued in-dependent of the positioner’s input signal(min. current 3.8 mA), the actual travel/an-gle of rotation is controlled in real-time. Ad-ditionally, the position transmitter providesthe possibility of signaling a positioner faultover a signal current of < 2.4 mA or> 21.6 mA.

Inductive limit switch

The rotary shaft of the positioner carries anadjustable tag which actuates the installedproximity switch. The optional inductive limitswitch (11) is connected to A1, while theremaining software limit switch is connectedto A2.

10 EB 8384-2 EN


External position sensor

In this version, only the sensor is mounted tothe control valve. The positioner is locatedseparately from the valve.The connection of x and y signals to thevalve is established by cable and piping forair (only without inductive limit switch).

Leakage sensor

By upgrading the positioner with a leakagesensor, it is possible to detect seat leakagewhen the valve is in the closed position.

Binary input

The positioner has an optional binary input.The following actions can be performed overthe binary input:

4 Transfer switching state [default]The switching state of the binary input islogged.

4 Set local operation write protectionSettings cannot be changed at thepositioner while the binary input is ac-tive. The configuration enabled functionin Code 3 is not active.

4 Switch between AUTO/MANThe positioner changes from automaticmode (AUTO) mode into manualmode (MAN) and vice versa.No action is started if the positioner is inthe fail-safe position (SAFE).

4 Various diagnostic functions (refer toEB 8389 on EXPERTplus valve diagnos-tics)

Note: The optional binary input can only beconfigured using the TROVIS-VIEW software(refer to EB 8389 on EXPERTplus valve diag-nostics).The default switching state is with an openswitch.

3.2 Configuration usingTROVIS-VIEW software

Refer to Table 6 on page 50 for order num-bers.

The positioner can be configured using theTROVIS-VIEW software.The positioner is equipped for this purposewith an additional digital SERIAL INTERFACEto allow a computer to be connected over anadapter cable from the RS-232 or USB portof the computer to the positioner.The TROVIS-VIEW software enables the userto easily set parameters in the positionerand view process parameters online.

Note: The TROVIS-VIEW software is a com-mon operator interface for various smartSAMSON devices. The software togetherwith a device-specific module allow the con-figuration and parameterization of the de-vice.The device-specific module for Type 3730-2can be downloaded free of charge from theSAMSON website (Services > Software >TROVIS-VIEW).Additional information on TROVIS-VIEW(e.g. system requirements) can found on theSAMSON website and in the Data SheetT 6661.

WARNING!Mount the positioner, keeping the followingsequence:1. Remove the protective film from the

pneumatic connections2. Mount the positioner on the control valve3. Connect the supply air4. Connect the electrical power5. Perform the start-up settings

The connection of the electrical auxiliarypower may cause the actuator stem to move,depending on the operating mode.Do not touch the actuator stem or obstruct itto avoid risk of injury to hands or fingers.

5.1 Pneumatic connections

NOTICEFollow the instructions below to avoid dam-aging the positioner.– The threaded connections in the

positioner housing are not designed di-rect air connection!

– The screw glands must be screwed intothe connecting plate, the pressure gaugemounting block or the connection blockfrom the accessories.The air connections are optionally de-signed as a bore with ¼ NPT or G ¼thread.The customary fittings for metal and cop-per pipes or plastic hoses can be used.

– The supply air must be dry and free fromoil and dust.The maintenance instructions for up-stream pressure reducing stations must

be observed.Blow through all air pipes and hosesthoroughly prior to connecting them.

If the positioner is attached directly to theType 3277 Actuator, the connection of thepositioner's output pressure to the actuator isfixed. For attachment according toIEC 60534-6 (NAMUR), the signal pressurecan be routed to either the top or bottom di-aphragm chamber of the actuator, depend-ing on the actuator's fail-safe action"actuator stem extends" or "actuator stemretracts".For rotary actuators, the manufacturer'sspecifications for connection apply.

5.1.1 Signal pressure gauges

To monitor the supply air (Supply) and sig-nal pressure (Output), we recommend thatpressure gauges be attached (see accesso-ries in Tables 1 to 7).

5.1.2 Supply pressure

The required supply air pressure depends onthe bench range and the actuator's operat-ing direction (fail-safe action).The bench range is registered on the name-plate either as spring range or signal pres-sure range depending on the actuator. Thedirection of action is marked FA or FE, or bya symbol.

Actuator stem extends FA (air to open)

Fail-close(for globe and angle valves):

Required supply pressure = Upper benchrange value + 0.2 bar, minimum 1.4 bar.

WARNING!The actuator stem moves while the start-upsettings are being performed.Do not touch the actuator stem or obstruct itto avoid risk of injury to hands or fingers.

NOTICEPerform the start-up settings in the same se-quence as listed (section 7.1 to section 7.6).

Note: The positioner performs a test in thestart-up phase while following its automa-tion task at the same time. During thestart-up phase, operation on site is unre-stricted, yet write access is limited.

7.1 Defining the valve closedposition

To adapt the positioner to the operating di-rection of the actuator, set slide switch to AIRTO OPEN or AIR TO CLOSE .

4 AIR TO OPEN = Signal pressure opensthe valve, for fail-safe position: actuatorstem extends/fail close

4 AIR TO CLOSE = Signal pressure closesthe valve, for fail-safe position: actuatorstem retracts/fail open.

NOTICEThe AIR TO OPEN (AtO) setting always ap-plies to double-acting actuators.

For checking purposes:After successfully completing initialization,the positioner display should read 0 % whenthe valve is closed and 100 % when thevalve is open. If this is not the case, changethe slide switch position and re-initialize thepositioner.

EB 8384-2 EN 59

Start-up – Settings

Note: The switch position is prompted priorto an initialization. After an initialization hasbeen completed, changing the switch posi-tion does not have any effect on the opera-tion of the positioner.

7.2 Setting the volume restrictionQ

The volume restriction Q is used to adapt theair delivery to the size of the actuator:

4 Actuators with a transit time < 1 s, e.g.linear actuators with an effective areasmaller than 240 cm², require a re-stricted air flow rate (MIN).

4 Actuators with a transit time ≥ 1 s do notrequire the air flow rate to be restricted(MAX).

The position of volume restriction Q also de-pends on how the signal pressure is routedat the actuator in SAMSON actuators:

4 The “SIDE“ position applies for actuatorswith a loading pressure connection at theside, e.g. Type 3271-5.

4 The “BACK“ position applies for actua-tors with a loading pressure connectionat the back, e.g. in Type 3277-5.

4 The “SIDE”restriction position always ap-plies for actuators from other manufac-turers.

Turn until the pressure in the positionerbuilds up, and the control valve moves to itsfinal positions so that the travel/angle of ro-tation can be checked.

EB 8384-2 EN 61


The angle of rotation on the back of thepositioner is indicated. A horizontal lever(mid position) is equal to 0°.

To ensure the positioner is working prop-erly, the outer bar elements may not blinkwhile the valve is moving through the oper-ating range.Exit Code 1 by pressing the rotarypushbutton ( ).

The permissible range has been exceededwhen the displayed angle is greater than30°, and the outer right or left bar elementblinks.The positioner changes to the fail-safe posi-tion (SAFE).After canceling the fail-safe position (SAFE)(see section 8.2.2) it is absolutely necessaryto check the lever and pin position as de-scribed in section 4.

WARNING!To avoid personal injury or property dam-age caused by the supply air or electricalauxiliary power, disconnect the supply airand electrical auxiliary power before ex-changing the lever or changing the pin posi-tion.

7.6 Initialization

WARNING!During initialization, the control valve movesthrough its entire travel/rotation range.Therefore, do not start the initialization pro-cedure while a process is running, but onlyduring start-up when all shut-off valves areclosed.

Before starting initialization, check the maxi-mum permissible signal pressure of the con-trol valve. During initialization, thepositioner issues an output signal pressureup to the maximum supply pressure sup-plied. If necessary, limit the signal pressureby connecting an upstream pressure reduc-ing valve.

NOTICEAfter the positioner has been mounted on toanother actuator or its mounting locationhas been changed and prior tore-initializing the positioner, the positionerneeds to be reset to its basic setting (defaultvalues). Refer to section 7.8.

During initialization the positioner adapts it-self optimally to the friction conditions andthe signal pressure demand of the controlvalve. The type and extent of self-adaptationdepends on the set initialization mode:

4 MAX maximum range (standard range)Initialization mode for simple start-up ofvalves with two clearly defined mechani-cal end positions, e.g. three-way valves(see section 7.6.1)

62 EB 8384-2 EN


4 NOM nominal rangeInitialization mode for all globe valves(see section 7.6.2)

4 MAN manually selected rangeInitialization mode for globe valves withan unknown nominal range (see section7.6.3)

4 SUB substitute calibration (emergencymode)This mode allows a positioner to be re-placed while the plant is running, withthe least amount of disruption to theplant (see section 7.6.4)

Note: For normal operation, simply start ini-tialization by pressing the INIT key aftermounting the positioner on the valve, defin-ing the valve closed position and setting thevolume restriction. The positioner only needsto work with its default settings. If necessary,perform a reset (see section 7.8).

After a successful initialization, thepositioner runs in closed-loop operation in-dicated by .

A malfunctioning leads to the process beingcanceled. The initialization error appears onthe display according to how it has beenclassified by the condensed state. See sec-tion 8.3.

Note: The setting Code 48 - h0 = YEScauses the reference graphs (drive signalsteady-state d1 and hysteresis d2) to beplotted automatically after initialization hasbeen completed. tESt d1 or tESt d2 appearon the display in an alternating sequence.An error during the plotting of the referencegraphs is indicated by Code 48 - h1 andCode 81.The positioner still works properly, eventhough the reference graph plotting has notbeen completed successfully.

Valve closed position AIR TO CLOSE

If the slide switch is set to AIR TO CLOSE,the positioner automatically switches to thedirection of action increasing/decreasing(äæ) on successful completion of initializa-tion.This results in the following assignment be-tween reference variable and valve position:

The calibrated sensor allows the effectivevalve travel to be set very accurately. Duringthe initialization process, the positionerchecks whether the control valve can movethrough the indicated nominal range (travelor angle) without collision.If this is the case, the indicated nominalrange is adopted with the limits oftravel/angle range start (Code 8) andtravel/angle range end (Code 9) as the op-erating range.

Note: The maximum possible travel must al-ways be greater than the nominal travel en-tered. If this is not the case, initialization isinterrupted (error alarm Code 52) becausethe nominal travel is not achieved.

7.6.4 SUb substitute calibration

A complete initialization procedure takesseveral minutes and requires the valve tomove through its entire travel range severaltimes. This initialization mode, however, isan emergency mode, in which the controlparameters are estimated and not deter-mined by an initialization procedure. As aresult, a high level of accuracy cannot beexpected. You should always select a differ-ent initialization mode if the plant allows it.

The SUb initialization mode is used to re-place a positioner while the process is run-ning. For this purpose, the control valve isusually fixed mechanically in a certain posi-tion, or pneumatically by means of a pres-sure signal which is routed to the actuatorexternally. The blocking position ensuresthat the plant continues to operate with thisvalve position.

By entering the blocking position (Code 35),closing direction (Code 34), pin position(Code 4), nominal range (Code 5) and di-rection of action (Code 7), the positionercan calculate the positioner configuration.

NOTICEPerform a reset before re-initializing thepositioner if the substitute positioner has al-ready been initialized. Refer to section 7.8.

9 Adjusting the limit switch

The positioner version with inductive limitswitch has one adjustable tag (1) mountedon the shaft which operates the proximityswitch (3).

For operation of the inductive limit switch,the corresponding switching amplifier (seesection 5.2.1) must be connected to the out-put.

If the tag (1) is inside the field of the switch,the switch assumes a high resistance. If thetag is outside of the field, the switch assumesa low resistance.

Normally, the limit switch is adjusted suchthat it will provide a signal in both end posi-tions of the valve. The switch, however, canalso be adjusted to indicate intermediatevalve positions.

The desired switching function, i.e. whetherthe output relay shall be picked up or re-leased when the tag has entered the field,has to be determined, if necessary, at theswitching amplifier.

Note:The inductive limit switch replaces the soft-ware limit switch A1 with terminal assign-ment +41/–42.Each switching position can optionally be setto indicate when the tag has entered thefield, or when it has left the field.The second software limit switch remains ef-fective, the function of the software limitswitch A1 is disabled.

Setting the switching point:

NOTICEDuring adjustment or testing, the switchingpoint must always be approached frommid-position (50 %).

To ensure safe switching under any ambientconditions, the switching point should be ad-justed to a value of approx. 5 % before themechanical stop (OPEN – CLOSED).

For CLOSED position:

1. Initialize positioner.2. Use the MAN function to move the

positioner to 5 % (see LC display).3. Adjust the tag using the yellow adjust-

ment screw (2) until the tag enters orleaves the field and the switching ampli-fier responds. You can measure theswitching voltage as an indicator.

Contact function:

4 Tag leaving the field > contact is made4 Tag entering the field > contact is

opened.

For OPEN position:

1. Initialize positioner.2. Use the MAN function to move the

positioner to 95 % (see LC display).3. Adjust the tag (1) using the yellow ad-

justment screw (2) until the tag enters orleaves the field of the proximity switch(3).You can measure the switching voltageas an indicator.

9.1 Retrofitting an inductive limitswitch

Required retrofit kit:Limit switch Order no. 1400-7460

Note: The same requirements apply toretrofitting an inductive limit switch as to ser-vicing the positioner. For explosion-pro-tected devices, the requirements in sec-tion 11 need to be kept.Check the "Limit switch, inductive" box onthe nameplate after retrofitting the limitswitch.

1. Take off the rotary pushbutton (3) andcap (1), unthread the five fixing screws(2) and lift off the plastic cover (9) to-gether with the display, taking care notto damage the ribbon cable (betweenPCB and display).

EB 8384-2 EN 77


2. Use a knife to cut an opening at themarked location (4).

3. Push the connector (11) with cablethrough the opening and secure theproximity switch (7) on the cover with adot of glue.

4. Remove the jumper (8801-2267) at thesocket X7 of the top board and insert thecable connector (11).

5. Guide the cable in such a manner thatthe plastic cover can be placed backonto the positioner. Insert the fixingscrews (2) and screw tight. Attach theclamping plate (8) onto the proximityswitch.

6. Attach the rotary switch (5). Make surethe flattened side of the positioner shaftis turned so that the rotary switch (5) canbe attached with the metal tag next tothe proximity switch.

7. Note: On start-up of the positioner, setthe option "inductive alarm" under Code38 from No to YES.

10 Maintenance

The positioner does not require any mainte-nance.

There are filters with a 100 µm mesh size inthe pneumatic connections for supply andoutput which can be removed and cleaned,if required.

The maintenance instructions of any up-stream supply air pressure reducing stationsmust be observed.

11 Servicing explosion-protecteddevices

If a part of the device on which the explo-sion protection is based needs to be ser-viced, the device must not be put back intooperation until a qualified inspector has as-sessed it according to explosion protectionrequirements, has issued an inspection cer-tificate or given the device a mark of confor-mity.

Inspection by a qualified inspector is not re-quired if the manufacturer performs a rou-tine test on the device prior to putting it backinto operation. The passing of the routinetest must be documented by attaching amark of conformity to the device. Replaceexplosion-protected components only byoriginal, routine-tested components from themanufacturer.

Devices that have already been operatedoutside hazardous areas and are intendedfor future use inside hazardous areas mustcomply with the safety requirements placedon serviced devices. Before being used in-side hazardous areas, test the devices ac-cording to the specifications for servicingexplosion-protected devices.

12 Firmware update (serialinterface)

Firmware updates on positioners currently inoperation can be performed as follows:

When updates are performed by a serviceemployee appointed by SAMSON, the up-date is confirmed on the positioner by thetest mark assigned by SAMSON’s QualityAssurance.

In all other cases, only persons from theplant operator with written approval mayperform updates. This person must confirmthe update on the positioner.

Laptops and PCs connected to the powersupply must use an additional safety barrier.

This does not apply to laptops in battery op-eration. In this case, it is assumed that a bat-tery-powered laptop runs briefly for soft-ware programming or for testing purposes.

a) Updates outside the hazardous area:

Remove the positioners from the plantand update them outside the hazardousarea.

EB 8384-2 EN 79

Maintenance

b) Updates on site:

Updates on site are only permitted afterthe plant operator has presented a sig-ned hot work permit.

After updating has been completed, add thecurrent firmware to the nameplate; this canbe done using labels.

13 Maintenance, calibration andwork on equipment

The interconnection with intrinsically safecircuits to check or calibrate the apparatusmust only be performed with intrinsicallysafe current/voltage calibrators and mea-suring instruments to rule out any damageto components relevant for explosion pro-tection.

The maximum values for intrinsically safecircuits specified in the approvals must bekept.

not central.• Follower plate incorrectly attached.

Status classification [Maintenance required]

Recommended action Check attachment and pin position, set operating mode fromSAFE to MAN and re-initialize the positioner.

51 ∆x < range The measuring span of the sensor is too low.

• Pin positioned incorrectly.• Wrong lever.

A rotational angle smaller than 16° at the positioner shaft onlygenerates a message. An angle below 9° leads to the initializati-on being canceled.


Recommended action Check attachment and re-initialize the positioner.

52 Attachment • Positioner attachment incorrect.

• Nominal travel/angle (Code 5) could not be reached duringinitialization under NOM (no tolerance downwardspermissible).

• Mechanical or pneumatic fault, e.g. wrong lever selected orsupply pressure too low to move to the required position.


Recommended action Check attachment and supply pressure. Re-initialize thepositioner.Under certain circumstances, it may be possible to check themaximum travel/angle by entering the actual pin position andthen performing an initialization under MAX.After initialization has been completed, the Code 5 indicates themaximum achieved travel or angle.
