1 Design and principle ofoperation

The electropneumatic positioner is mountedto pneumatic control valves and is used toassign the valve position (controlledvariable x) to the control signal (referencevariable w). The DC control signal receivedfrom a control unit is compared to the travelor rotational angle of the control valve andissues a signal pressure (output variable y).

The positioner is designed depending on thecorresponding accessories for direct attach-ment to Type 3277 Actuators or for attach-ment to actuators according to IEC 60534-6(NAMUR).Additionally, a coupling wheel included inthe accessories is required to transfer the ro-tary motion for rotary actuators according toVDI/VDE 3845.

Springless rotary actuators require an ac-cessory reversing amplifier to permit thepowered operation in either direction.

The positioner basically consists of a travelsensor system that functions proportional toresistance, an analog i/p module withdownstream booster as well as the electronicunit with a microcontroller. The positioner isfitted with two adjustable software limitswitches as standard to indicate the valve'send positions.

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 tothe 4 to 20 mA DC control signal (reference

variable) after it has been converted by theA/D converter (4).In case of a system deviation, the operationof the i/p converter (6) is changed so thatthe actuator (1) is filled or vented via thedownstream air capacity booster (7). Thiscauses the closure member of the controlvalve to move to the position determined bythe reference variable.The pneumatic air capacity booster (7) andthe pressure regulator (8) are provided withsupply air. An intermediate flow regulator(9) with fixed settings is used to purge thepositioner and also guarantees trouble-freeoperation of the pneumatic booster.The output signal pressure supplied by thebooster can be limited to 2.4 bar by activat-ing the parameter P9.The volume restriction Q (10) is used to opti-mize the positioner by adapting it to the ac-tuator size.

Tight-closing function:The pneumatic actuator is completely filledwith air or vented as soon as the referencevariable falls below 1 % or exceeds 99 %(see end positions set over parameters P10and P11).

2 Attachment to the controlvalve – mounting parts andaccessories

The positioner can be attached either di-rectly to a SAMSON Type 3277 Actuator oraccording to IEC 60534-6 (NAMUR) to con-trol valves with cast yokes or rod-type yokesas well as to rotary actuators according toVDI/VDE 3845.

For attachment to the various actuators, cor-responding mounting parts and accessoriesare required. These are listed with their or-der numbers in Tables 1 to 5.

On attaching the positioner, it is importantto observe the assignment between leverand pin position according to the travelslisted in the travel tables.

The actual valve travel that can be achievedis restricted by the pin position used and ad-ditionally by the actuator spring compres-sion required.The travel range listed in the travel tablescan only achieved if the nominal range is setto MAX.The positioner is standard equipped with thelever M (pin position 35).

Note!If the standard mounted lever M (pin posi-tion 35) is replaced, the newly mounted le-ver must be moved once all the way as faras it will go in both directions to adapt it tothe internal measuring lever.

2.5 Reversing amplifier fordouble-acting actuators

For the use with double-acting actuators, thepositioner must be fitted with a reversingamplifier. The reversing amplifier is listed asan accessory in the Table 5 on page 11.

The output signal pressure of the positioneris supplied at the output A1 of the reversingamplifier. An opposing pressure, whichequals the required supply pressure whenadded to the pressure at A1, is applied atoutput A2.The rule A1 + A2 = Z applies.

Mounting

1. Mount the connecting plate (6) from theaccessories in Table 4 to the positioner.Make sure that both O-rings (6.1) areseated correctly.

2. Thread the special nuts (1.3) from theaccessories of the reversing amplifierinto the boreholes of the connectingplate.

3. Insert the gasket (1.2) into the recess ofthe reversing amplifier and push boththe special hollow screws (1.1) into theconnecting boreholes A1 and Z.

4. Place the reversing amplifier onto theconnecting plate (6) and screw tight us-ing both the special screws (1.1).

5. Use a screwdriver (8 mm wide) to screwthe enclosed filters (1.6) into the con-necting boreholes A1 and Z.

Note!The sealing plug (1.5) should not be un-screwed out of the reversing amplifier.The rubber seal (1.4) is not required andcan be removed when the sealing plug isused.

3 Connections

3.1 Pneumatic connections

Caution!The threads in the positioner housing are notdesigned for direct air connection!

The screw glands must be screwed into theconnecting plate, the pressure gauge mount-ing block or the connection block from theaccessories. The air connections are option-ally designed as a bore with ¼ NPT or G ¼thread.The customary fittings for metal and copperpipes or plastic hoses can be used.

Note!The supply air must be dry and free from oiland dust. The maintenance instructions forupstream pressure reducing stations must beobserved.Blow through all air tubes and hoses thor-oughly prior to connecting them.

If the positioner is attached directly to theType 3277 Actuator, the connection of thepositioner's output pressure to the actuatoris fixed. 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 "Actua-tor stem extends" or "Actuator stem re-tracts".For rotary actuators, the manufacturer'sspecifications for connection apply.

3.1.1 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 5).

3.1.2 Supply pressure

The required supply air pressure dependson the bench range and the actuator's oper-ating direction (fail-safe action). The benchrange is registered on the nameplate eitheras spring range or signal pressure range.The direction of action is marked FA or FE,or by a symbol.

Actuator stem extends FA (Air to openATO)

Fail-safe position "Valve Closed"(for globe and angle valves):

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

Actuator stem retracts FE (Air to close ATC)

Fail-safe position "Valve Open"(for globe and angle valves):For tight-closing valves, the maximum signalpressure pstmax is roughly estimated as fol-lows:

3.2 Electrical connections

For electrical installation, you are re-quired to observe the relevant elec-trotechnical regulations and the acci-dent prevention regulations that ap-ply in the country of use. In Germa-ny, these are the VDE regulationsand the accident prevention regula-tions of the employers' liability insu-rance association.The following standards apply for in-stallation in hazardous areas:EN 60079-14: 2003 (VDE 0165Part 1) "Electrical apparatus for ex-plosive gas atmospheres" andEN 50281-1-2: 1999 (VDE 0165Part 2) "Electrical apparatus for usein the presence of combustibledust".For the interconnection of intrinsical-ly safe electrical equipment, the per-missible maximum values specifiedin the EC type examination certifica-te apply (Ui or Uo; Ii or Io; Pi or Po; Cior Co, and Li or Lo).For EEx nA equipment (non-sparkingapparatus), the standard EN 50021:1999 specifies that connecting, inter-rupting, or switching circuits whileenergized is only allowed during in-stallation, maintenance or repairwork.For EEx nL equipment (energy-limit-ed apparatus), the standardEN 50021: 1999 allows this type ofequipment to be switched under nor-mal operating conditions.

Caution!The terminal assignment specified in the cer-tificate must be adhered to. Reversing theassignment of the electrical terminals maycause the explosion protection to become in-effective!Do not tamper with enameled screws insideor on the housing.

Note on the selection of cables and wires:To install intrinsically safe circuits, observesection 12 of the standard EN 60079-14:2003 (VDE 0165 Part 1). To run multi-corecables or lines with more than one intrinsi-cally safe circuit, section 12.2.2.7 of thisstandard applies.An additional cable gland can be installedwhen connecting the device over two sepa-rate cables. Cable entries left unused mustbe sealed with blanking plugs. Devices usedat ambient temperatures down to –40 °Cmust have metal cable entries.

Cable entries

The cable entry with M20x1.5 cable gland,6 to 12 mm clamping area.There is a second M20x1.5 threaded borein the housing that can be used for addi-tional connection, when required.The screw terminals are designed for wirecross-sections of 0.2 to 2.5 mm². Tighten byat least 0.5 Nm.

The wires for the reference variable must beconnected to the terminals 11 and 12 lo-cated in the housing. Only use a currentsource!

26 EB 8384-1 EN

Connections

Caution!The erroneous connection of a voltagesource of just around 7 V (or around 2 Vwhen connected to the wrong pole) candamage the positioner.

In general, it is not necessary to connect thepositioner to a bonding conductor. Shouldthis be required, however, this conductorcan be connected inside the device.

For operation of the limit switches in Type3730-11/-13/-18 Positioners, switchingamplifiers which comply withEN 60947-5-6 must be connected to termi-nals 41/42 and 51/52 in the output circuit.If the positioner is to be installed in hazard-ous areas, the relevant regulations must beobserved.

Refer to Fig. 10 for the terminal assignment.

Note!The minimum permissible reference variableshould not fall below 3.7 mA.

Volume restriction Q

The volume restriction is used to adapt theair delivery to the actuator size. Two fixedsettings are possible depending on how theair is routed at the actuator. See section 5.1for more details.

Display

The LC display indicates symbols that areassigned to codes and functions. The bargraph indicates the system deviation thatdepends on the sign (+/–) and the value.One bar graph element appears per 1 %system deviation.If the positioner is not initialized, the leverposition in degrees in relation to the longitu-dinal axis is indicated instead of the systemdeviation. One bar graph element corre-sponds to approximately a 5° angle.

If the fault symbol appears on the dis-play, turn the button until ERR appearsto view the error code(s) E0 to E15. Refer tosection 5.6 for details.

5 Start-up

Warning!Do not perform a start-up while theprocess is running.On applying supply air and the elec-tric control signal, the control valvemay move through its entire travelrange/rotational angle range de-pending on the setting.

� Connect the supply air (Supply 9).� Apply the electric reference variable 4 to

20 mA (terminals 11 and 12).

Note! For most applications, the positioneris ready for operation with its default set-tings, provided it is attached properly.The positioner just needs to be initialized af-ter the volume restriction has been set andthe fail-safe position has been determined.

5.1 Setting the volume restriction Q

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

� 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).

� 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:

EB 8384-1 EN 29

Start-up

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

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

The “SIDE” restriction position always appliesfor actuators from other manufacturers.

5.5 Initialization

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-adaptation de-pends on the preset parameters.MAX is the default setting for the nominalrange (Code P4). During the initializationprocess, the positioner determines thetravel/rotational angle of the closing ele-ment from the CLOSED position as far as itwill go in the other direction.

Note!For standard operation, after the positioneris mounted on the valve and the volume re-striction has been set and the fail-safe posi-tion has been checked over Code P2, startinitialization over Code P15 to ensure theoptimal functioning of the positioner.The positioner works with its standard set-tings (default settings).

Warning!During the initialization, the controlvalve moves through its entire tra-vel/angle of rotation range. Therefo-re, do not start initialization while aprocess is running, but only duringstart-up, when all shut-off valves areclosed.

If a part of the positioner on which the explo-sion protection is based needs to be serviced,the positioner must not be put back into op-eration until an expert has inspected the de-vice according to explosion protection re-quirements, has issued a certificate statingthis or given the device a mark of conformity.

Inspection by an expert is not required if themanufacturer performs a routine test on thedevice prior to putting it back into operation.The passing of the routine test must be docu-mented by attaching a mark of conformity tothe device.

Devices that have already been used outsideof hazardous areas and are intended for usein hazardous areas in future must complywith the safety demands placed on repaireddevices. Prior to operation, they must betested according to the specifications stipu-lated for "Repairing explosion-protected de-vices".
