Safety instructions

General safety instructions

� The positioner may only be assembled, started up or operated by trainedand experienced personnel familiar with the product.According to these mounting and operating instructions, trained personnel isreferred to as individuals who are able to judge the work they are assignedto and recognize possible dangers due to their specialized training, theirknowledge and experience as well as their knowledge of the relevant stan-dards.

� Explosion-protected versions of this positioner may only be operated by per-sonnel who have undergone special training or instructions or who are au-thorized to work on explosion-protected devices in hazardous areas. Referto section 6 on Servicing explosion-protected versions.

� Any hazards that could be caused by the process medium, the operatingpressure, the signal pressure or by moving parts of the control valve are tobe prevented by means of the appropriate measures. If inadmissible motionsor forces are produced in the actuator as a result of the supply pressurelevel, it must be restricted by means of a suitable supply pressure reducingstation.

� Proper shipping and appropriate storage are assumed.

� Note: The device with a CE marking fulfils the requirements of the Directives94/9/EC (ATEX) and 89/336/EEC (EMC).The declaration of conformity is available on request.

1 Design and principle ofoperation

The positioner consists of an electro-pneumatic converter unit (i/p converter) anda pneumatic unit equipped with a lever fortravel pick-up, a measuring diaphragm, andthe pneumatic control system with nozzle,diaphragm lever (flapper plate) and booster.

The positioner is designed either for directattachment to SAMSON Type 3277 Actua-tors or for attachment according to NAMUR(IEC 60534-6) with an adapter housing.The positioner can be additionally equippedwith either inductive limit switches and/or asolenoid valve or a position transmitter.

The DC control signal, e.g. 4 to 20 mA, is-sued by the control unit is transmitted to theelectropneumatic conversion unit (13) whereit is converted into a proportional pressuresignal pe.The positioner operates according to theforce-balance principle. The valve travel, i.e.the valve position, is transmitted to thepick-up lever (1) over the pin (1.1) and de-termines the force of the measuring spring(4). This force is compared to the positioningforce generated by the pressure pe at themeasuring diaphragm (5).If either the control signal or the valve posi-tion changes, the diaphragm lever (3)moves, altering the distance to the nozzle(2.1 or 2.2), depending on the set operatingdirection of the positioner.The air is supplied to the booster (10) andthe pressure regulator (9). The controlledsupply air is fed to the i/p module, thenflows through the Xp restriction (8) and thenozzle (2.1, 2.2) to finally stream on the di-aphragm lever (flapper plate). Any change

in the reference variable or the valve stemposition cause the pressure to change up-stream or downstream of the booster. Theair controlled by the booster (signal pressurepst) flows through the volume restriction (11)to the pneumatic actuator, causing the plugstem to move to a position corresponding tothe DC input signal (reference variable).

The adjustable Xp restriction (8) and volumerestriction (11) are used to optimize thepositioner control loop. The pick-up lever (1)and the range spring (4) must be selected tomatch the rated valve travel and the nominalspan of the reference variable.

Positioner with inductive limit switches

In this version, the rotary shaft of thepositioner carries two adjustable tags whichactuate the built-in proximity switches.

Positioner with solenoid valve

When the positioner is equipped with a so-lenoid valve, the control valve can be movedto the fail-safe position regardless of thepositioner's output signal. If a control signalcorresponding to the binary signal "0" (off)is applied to the input, the signal pressurepst is shut off and the actuator is vented. Theactuator springs move the control valve to itsfail-safe position. If a control signal corre-sponding to the binary signal "1" (on) is ap-plied to the input, the signal pressure pst issupplied to the actuator. The control valve isin control operation.

Positioner with position transmitter

A positioner containing a position transmit-ter cannot be equipped with integrated limitswitches or an integrated solenoid valvesince the position transmitter requires mostof the space inside. The position transmitteris used to establish a certain relationship be-tween the valve position, i.e. the valve travel,and a controller output signal of 4 to 20mA. The position transmitter setting ensuresthat both end positions "valve CLOSED" or"valve OPEN" as well as all intermediatepositions can be signalized. Since the valveposition is signalized independently of theinput signal to the positioner, the positiontransmitter is a suitable option for checkingthe current valve position.

2 Attachment to control valve

The positioner is attached either directly toSAMSON Type 3277 Actuator or to valveswith cast yokes or with rod-type yokes in ac-cordance with IEC 60534-6 (NAMUR).When combined with an intermediate piece,the device can also be attached to rotary ac-tuators as a rotary positioner. As thepositioner is also available as a basic unitwithout accessory equipment, refer to the ta-bles on the following pages for both the re-quired mounting parts and their associatedorder numbers.Do not remove the protective cover on theback of the positioner before actually start-ing to attach the positioner.

Mounting position and operating direction

The operating direction of the positioneralso determines its mounting position on theactuator as illustrated in Figs. 3, 4 and 6.The turnboard (7, Fig. 2) at the positionermust be mounted correspondingly. For anincreasing input signal (reference variable),the signal pressure pst can either be increas-ing (direct action >>) or decreasing (reverseaction <>). This also applies when the refer-ence variable decreases: direct action >>causes the signal pressure to decrease, re-verse action <> causes the signal pressure toincrease.

On the turnboard (7), the operating direc-tion is indicated by symbols (direct >>, re-verse <>). Depending on the position of theturnboard, the adjusted operating directionand the associated symbol become visible.

If the required operating direction does notcorrespond to the visible symbol, or if you

want to change the operating direction, re-move the fastening screw at the turnboard,turn the board by 180°, and refasten theturnboard with the screw. Make sure thethree rubber gaskets inserted in the housingremain in position.

Note: When any subsequent changes aremade, e.g. reversing the operating directionof the positioner control loop or changingthe actuator from “Actuator stem extends” to“Actuator stem retracts” or vice versa, thepositioner's mounting position must bechanged accordingly.

2.1 Direct attachment to Type3277 Actuator

Required accessories are listed in Tables 1to 4 on page 14.

The attachment of the positioner either onthe left or right side of the actuator (alwayslooking at the signal pressure connection orswitchover plate) is determined by the re-quired operating direction of the positioner,i.e. >> or <>.

7. Make sure that the tip of the gasket (16)projecting from the side of the connec-tion block (Fig. 3, middle) is positionedto match the actuator symbol that corre-sponds to the actuator's fail-safe action"Actuator stem extends" or "Actuatorstem retracts."If necessary, remove the three fixingscrews and the cover. Reposition the gas-ket (16) turned by 180°.The old connection block version re-quires the switch plate (13) to be turnedsuch that the corresponding actuatorsymbol points to the marking.

8. Place the connection block with its sealson the positioner and the actuator yokeand screw tight using the fasteningscrew.Actuators with "Actuator stem retracts"require the ready-made signal pressureline to be installed.

Actuators with 120 cm² diaphragm area

The signal pressure is transmitted to the dia-phragm chamber over the switchover plate(Figs. 3 and 4, bottom).

7. Remove the screw in the rear cover of thepositioner (Fig. 5) and seal the lateralsignal pressure output "output" with theplug contained in the accessories kit.

8. Mount the positioner such that the borein the distance plate (15) mates with theseal in the bore of the actuator yoke.

9. Align the switchover plate with the corre-sponding symbol and fasten it to the ac-tuator yoke.

Note: When a solenoid valve or a similardevice is attached to the 120 cm² actuator inaddition to the positioner, do not remove therear M3 screw plug. In this case, the signalpressure must be transmitted from the signalpressure output to the actuator over an addi-tional connecting plate (Table 2). Theswitchover plate is not used.

Filling the actuator with air

If the spring chamber of the actuator mustbe filled with the positioner's exhaust air,

12 EB 8355-2 EN


use piping (Table 3) to connect the springchamber (with version "Actuator stem ex-tends") to the connection block. To do so, re-move the plug from the connection block.

For version "Actuator stem retracts" andType 3277-5 Actuators with an effective di-aphragm area of 120 cm², an internal borehole ensures that the spring chamber is filledwith air.

Note: When the valve is installed, the sidecover of the actuator must be mounted suchthat the vent plug points downward.

The rotary motion of these actuators is con-verted into a linear motion required by thepneumatic control unit of the positioner us-ing the cam disk of the actuator shaft and acam follower roll on the positioner lever.

Note: Use Table 7 to check whether theproper range spring (1 or 2) has been in-stalled. Range spring 1 is installed as stan-dard. If necessary, replace it with rangespring 2 included in the accessories and at-tach it at the outer slot.

Double-acting springless rotary actuators re-quire the use of a reversing amplifier on theconnection side of the positioner housing(see section 2.3.4).When using a reversing amplifier, the pres-sure regulator (9, Fig. 2) must be turnedclockwise as far as it will go (also see sec-tion 3.1.2).When attaching the positioner to theSAMSON Type 3278 Rotary Actuator (Fig.8, left), the actuator's inside and the unusedreverse side of the diaphragm are filled withthe positioner's exhaust air. Additional pip-ing is not required. When attaching thepositioner to actuators from other manufac-turers (Fig. 8, right), the reverse side of thediaphragm can be filled with air over a pipeconnection installed between the actuatorand the intermediate piece.

2.3.1Mounting the cam followerlever

1. Place the lever with the cam follower roll(35) on the side of the feedback lever

(37) opposite the insert nuts. Fasten withthe supplied screws (38) and washers.

Note: To ensure a close physical contact be-tween the cam follower roll and the camdisk, fix the spring contained in the accesso-ries kit (order no. 1400-6660) at the rear ofthe positioner housing (see Fig. 5).

2.3.2Mounting the intermediatepiece

2.3.3Default setting of the camdisk

The valve model used determines the defaultsetting of the cam disk.

Note: Cam disks tailored to the special char-acteristic of a valve cause the valve to openin a non-linear or non-equal percentageway. The visible difference between the setpoint (4 to 20 mA) and the actual value(opening angle) does not constitute a systemdeviation of the positioner.

Figs. 9 and 10 show linear cam disks.

Fig. 9 illustrates a control valve assemblywith a spring-loaded rotary actuator thatopens counterclockwise. The arrangement ofthe springs in the actuator determines thefail-safe position of the valve.

Fig. 10 shows how to adjust the cam diskwhen a double-acting springless rotary actu-ator is used. The direction of rotation, eithercounterclockwise or clockwise, depends onthe actuator and valve model used. The camdisk must be set when the valve is closed.

Use the turnboard (7) to adjust the operatingdirection of the positioner, i.e. whether thevalve opens or closes when the referencevariable increases (direct >> or reverse <>).Each cam disk carries two cam sectionswhose starting points are indicated by smallbores. Depending on the operating directionof the rotary actuator – signal pressureopens or closes the valve – the starting pointof the cam, either marked N (standard char-acteristic) or I (reverse characteristic), mustpoint towards the cam follower roll. Whenthe starting point is located on the back ofthe cam disk, turn over the cam disk.

Note: The starting point (bore) of the se-lected cam section must be aligned with thefulcrum of the cam disk, the 0° position ofthe scale, and the arrow symbol on the in-spection glass.

When aligning the cam disk, the dou-ble-sided scale disk must be clipped on thecam disk such that the value on the scalecorresponds to the control valve's directionof rotation.

Note: Make sure the 0° position of the scalealways corresponds to CLOSED position.For actuators with fail-safe position "ValveOPEN" and for springless actuators, it istherefore necessary to apply the maximumsupply pressure to the actuator before align-ing the cam disk.

2.3.4Reversing amplifier fordouble-acting actuators

For the use with double-acting actuators, thepositioner must be fitted with a reversingamplifier, e.g. the SAMSON Type 3710 Re-versing Amplifier (see Mounting and Oper-ating Instructions EB 8392 EN).

The output signal pressure of the positioneris supplied at output A1 of the reversing am-plifier. An opposing pressure, which equalsthe required supply pressure when added tothe pressure at A1, is supplied at output A2.A1 + A2 = Z applies.

If a different reversing amplifier (item no.1079-1118 or 1079-1119) is used, followthe mounting instructions described below:

NOTICEWhen using the reversing amplifier, thepressure regulator (9) must be turned clock-wise as far as it will go.

Mounting

Note: Remove the sealing plug (1.5) beforeinstalling the reversing amplifier. The rubberseal (1.4) must remain installed.

1. Screw the special nuts (1.3) included inthe accessories of the reversing amplifierinto the threaded connections of thepositioner.

2. Insert the gasket (1.2) into the recess ofthe reversing amplifier and push the twohollowed special screws (1.1) into theconnecting bore holes A1 and Z.

3. Place the reversing amplifier onto thepositioner and screw tight using the twospecial screws (1.1).

4. Screw the supplied filter (1.6) using ascrewdriver (8 mm wide) into the con-necting bore holes A1 and Z.

Signal pressure connections

A1: Connect output A1 to the signal pressureconnection on the actuator that opens thevalve when the pressure increases.

A2: Connect output A2 to the signal pressureconnection on the actuator that closes thevalve when the pressure increases.

3.1 Pneumatic connections

The pneumatic connections are designed astapped holes with ¼ NPT or G ¼ thread.The conventional male connections for metaland copper pipes (or plastic hoses) can beused.

Note: The supply air must be dry and free ofany oil and dust.Always observe the maintenance instructionsapplicable to the connected pressure reduc-ing stations. Blow out air lines thoroughlybefore connecting them.

When attaching the Type 3277 Actuator di-rectly, the signal pressure connection isfixed. When using NAMUR attachment, thesignal pressure line is connected to either theupper or lower diaphragm chamber of theactuator depending on the actuator'sfail-safe action, i.e. "Actuator stem retracts"or "Actuator stem extends".

Exhaust air

Positioners with model index 3767-x...x.03or higher are equipped with a hinged coverwithout a vent connection. The required ex-haust air connection for these models arenow included in the mounting accessories.For direct positioner attachment, the ventplug is located on the plastic cover of the ac-tuator; for NAMUR attachment, it is locatedon the adapter housing, and for attachmentto rotary actuators the vent plug can befound on the intermediate piece or the re-versing amplifier.

Note: When using older models with index3767-x...x. 02 or lower, mounting parts willhave to be replaced as well.

3.1.1Pressure gauge

To monitor the positioner, we recommend toinstall pressure gauges for the supply airand the signal pressure.The required parts are listed as accessoriesin Tables 4, 5 or 7.

3.1.2Supply pressure

The required supply pressure is determinedby the bench range and the operating direc-tion (fail-safe action) of the actuator.The bench range is written on the nameplateas spring range or signal pressure rangedepending on the type of actuator. FA (actu-ator stem extends) or FE (actuator stem re-tracts) or a symbol indicates the operatingdirection.

Actuator stem extends (FA):Fail-safe position "Valve CLOSED"(for globe and angle valves)

Pressure regulator

After tilting the cover plate back, the pres-sure regulator (9) can be continuously ad-justed. When the adjuster is turned counter-clockwise as far as it will go, signal pres-sures for spring ranges up to 2.5 bar arecontrolled. When the adjuster is turnedclockwise all the way, signal pressures forspring ranges up to 6.0 bar are controlled.

If the signal pressure must not exceed a cer-tain value, this limit can be adjusted using apressure gauge (accessories).

4 Operation

4.1 Adjusting the positioner at thevalve

Starting point and reference variable

When adjusting the positioner directly at thecontrol valve, the travel (opening angle)must be adapted to the reference variable.With a reference variable, for example, 4 to20 mA, the valve must pass through its en-tire travel range from 0 to 100 % (Fig. 13,left).

For rotary positioners, an opening angle, forexample, 0 to 70° must be assigned to thereference variable.

The starting point refers to CLOSED positionof the valve.

Depending on the actuator version ("Actua-tor stem extends" or "Actuator stem re-tracts") and the operating direction of thepositioner (>> or <>), this starting point canbe represented by either the lower or upperrange value (4 or 20 mA) of the reference

variable. The reference variable range andthus the upper range value determine thetravel of the valve.

In split-range operation (Fig. 13, right), thecontrol valves operate on smaller referencevariables. The controller output signal isused to control two control valves, dividing itsuch that the valves pass through their entiretravel range at half the input signal rangeeach (e.g. first valve set to 4 to 12 mA, sec-ond valve set to 12 to 20 mA). To avoidoverlapping, allow for a dead band of±0.5 mA as shown in Fig. 13.

The starting point (zero) is adjusted at thezero adjuster screw (6.2); the span, i.e. theupper range value, is adjusted at the spanadjuster screw (6.1).

When adjusting, connect a suitable ammeterto the signal input and apply a supply pres-sure to the supply air input.

Note: When the positioner is controlled by acomputer whose signal is limited, e.g. be-tween 4 to 20 mA, set the positioner to therange from 4.5 to 20 mA.This is the only way to ensure that the actua-tor is completely vented and the valve com-pletely closed when the controller issues a4 mA signal.For operating direction <>, set the range to4 to 19.5 mA.

4.1.1Adjusting the proportionalband Xp and air delivery Q

1. Close the volume restriction (11) as faras the required positioning speed per-mits.To check, push the diaphragm lever (3)as far it will go.

2. Adjust the reference variable at the inputto approx. 50 % of its range.

3. Turn the zero adjuster (6.2) until thevalve has reached approx. mid-travel.

4. Use the adjuster (8) to set the propor-tional band Xp to a medium value (½turn).

5. Check the valve's tendency to hunt andthe positioning speed by briefly tappingthe diaphragm lever (3).The Xp value is to be adjusted to be assmall as possible, without considerableovershooting occurring.

Note: Always adjust the Xp restriction be-fore setting the starting point.Later modifications shift the zero point!

4.1.2Adjusting the actuator:"Actuator stem extends"

Starting point (e.g. 4 mA)

1. Set the input signal to 4 mA using anammeter.

2. Turn the zero adjuster (6.2) until the con-trol valve just starts to move from its ini-tial position.

3. Switch off the input signal and slowly in-crease it again. Check whether the valvestarts to move at exactly 4.5 mA. Correctany deviation on the zero adjuster (6.2).

Upper range value (e.g. 20 mA)

1. Once the starting point has been set, in-crease the input signal to 20 mA usingthe ammeter.

At exactly 20 mA, the plug stem must standstill, having passed through 100 % travel(watch the travel indicator at the valve).If the upper range value is incorrect, turn thespan adjuster (travel). Four turns corre-spond to a travel change of 10 % in stan-dard operation. In split-range operation, thisvalue is reduced by half. Turn the adjusterclockwise to reduce the travel and counter-clockwise to increase it.

2. After correction has been completed,switch off the control signal and increaseit again. Check the starting point and theupper range value. Repeat the correctionprocedure until both values are correct.

Note: When setting the zero adjuster (6.2),check whether the actuator is relieved ofpressure.

EB 8355-2 EN 33

Operation

When the input signal is 4 mA and the op-erating direction >>, or the input signal is20 mA and the operating direction <>, thepressure gauge must indicate 0 bar. Correctzero accordingly!

4.1.3Adjusting the actuator:"Actuator stem retracts"

Note: When using an actuator with fail-safeaction "Actuator stem retracts", the dia-phragm chamber must be pressurized witha signal pressure sufficient to close the valvetightly even when an upstream pressure isapplied in the plant. This applies to an up-per range value of the reference variable of20 mA and operating direction >>, and alower input range value of 4 mA and oper-ating direction <>.

The required signal pressure is either indi-cated on the positioner label or can beroughly calculated as described in section3.1.2.

Starting point (e.g. 20 mA)

1. Set the input signal to 20 mA using anammeter.

2. Turn the zero adjuster (6.2) until thevalve just starts to move from its initialposition.

3. Increase the input signal and slowly re-duce it to 20 mA again. Check whetherthe valve starts to move at exactly20 mA.

4. Correct any deviations on the zero ad-juster (6.2). Turning the adjuster counter-clockwise causes the valve to move fromits end position earlier; turning it clock-wise causes the valve to move from itsend position later.

Upper range value (e.g. 4 mA)

1. Once the starting point has been set, ad-just the input signal to 4 mA using theammeter. At exactly 4 mA, the plug stemmust stand still, having passed through100 % travel (watch travel indicator atthe valve).

2. If the upper range value is incorrect, turnthe span adjuster (travel). Four turns cor-respond to a travel change of 10 % instandard operation. In split-range opera-tion, this value is reduced by half. Turnthe adjuster clockwise to reduce the traveland counterclockwise to increase it.

3. After correction has been completed, re-set the control signal to 20 mA.

4. Turn the zero adjuster (6.2) again untilthe pressure gauge indicates the re-quired signal pressure (see section3.1.2).

Note: After attaching and calibrating thepositioner, make sure that the vent plug onthe housing cover points downward whenthe valve is installed in the plant.

Operation

4.3 Adjusting the limit switches

The positioner version with inductive limitswitches has two adjustable tags mountedon a rotary axis which operate the associ-ated proximity switches (50).

To operate the inductive limit switches, con-nect the corresponding switching amplifiersin the output circuit (see section 3.2.1).

When the tag (51) is inside the inductivefield of the switch, the switch assumes a highresistance. When the tag is outside the field,the switch assumes a low resistance. Thelimit switches are usually adjusted to issue asignal for both end positions. Nevertheless,they can also be set to signalize intermedi-ate positions. The switches A and B must beassigned to the end positions of the controlvalve (valve OPEN or CLOSED) dependingon the operating direction and the mountingposition according to Tables 8 and 9. Theterminals 41/42 and 51/52 can optionallybe assigned to the switches A and B by turn-

ing the associated nameplate on the termi-nal block (also see Fig. 12).

Note: As the tags of the limit switches can-not be turned by 360°, make sure that theswitches A and B are correctly assigned tothe end positions "valve OPEN" and "valveCLOSED", especially when the limit switchesare to be used for fail-safe circuits.

The desired switching function, i.e. whetherthe output relay must be picked up or re-leased when the tag has entered the field,must be determined by means of jumpers foreither working current or closed circuit cur-rent at the switching amplifier.

Operation

Fig. 14 · Limit switch

Setting the switching point

Move the valve to the switching position andadjust the tag by turning the adjustmentscrew (53) so that the switching point isreached and indicated by the LED on theswitching amplifier. To ensure safe switchingunder any condition, the switching point isto be adjusted to stop approx. 2 % beforethe mechanical stop (OPEN – CLOSED) isreached.

Note: After calibrating the positioner, makesure that the vent plug on the housing coverpoints downward when the valve is installedin the plant.

4.4 Adjusting the positiontransmitter

Note: The starting point (zero) and upperrange value (span) must be set before cali-brating the position transmitter.

Depending on the position of the 4-pin plug(symbol on plug: >> or <>), the feedbacksignal can be set to either a range of 4 to20 mA or 20 to 4 mA for 0 to 100 % travel.

Zero point (ZERO)

Use the switches 1 and 2 to preset the zeropoint and the ZERO potentiometer forfine-tuning. The adjusted value always refersto 4 mA.

Span (SPAN)

Use the switches 3 and 4 to preset the span,i.e. the upper range value, and the SPANpotentiometer for fine-tuning. The adjustedvalue always refers to 20 mA.

Example:Move the valve to open position while ob-serving the position transmitter signal. If thesignal does not move in the desired direc-tion, switch over the multi-pin plug. Adjustthe zero point (4 mA) and span (20 mA) forthe valve positions according to Table 10.

Fig. 15 · Position transmitter

Adjusting the zero point

1. Use the input signal of the positioner tomove the valve to closed position (valveCLOSED – travel 0 %).

2. The ammeter must now indicate approx.4 mA.

3. Correct smaller deviations on the ZEROpotentiometer until the meter shows ex-actly 4 mA. If deviations are too highand cannot be corrected using the poten-tiometer (adjustment range of approx.20 turns), set the switches 1 and 2 to in-dicate an mA value which is within theadjustment range of the ZERO potenti-ometer.

4. Set the zero point to exactly 4 mA usingthe ZERO potentiometer.

Adjusting the span

1. Use the input signal of the positioner tomove the valve to open position (valveOPEN – travel 100 %).

2. The ammeter must now indicate approx.20 mA.

3. Correct smaller deviations on the SPANpotentiometer until the meter shows ex-actly 20 mA. If deviations are too high,set the switches 3 and 4 to indicate anmA value which is within the adjustmentrange of the SPAN potentiometer.

4. Turn the SPAN potentiometer until themeter shows exactly 20 mA. Since zeroand span have a mutual influence oneach other, repeat the correction proce-dure at both potentiometers until bothvalues are correct.

Note on adjusting the position transmitterfor positioners with NAMUR adapterhousingWhen the positioner and the positiontransmitter signal have different operatingdirections (<< and <>), the zero point of thetransmitter signal could be unadjustable dueto the additional deflection caused by thebracket (28, Fig. 7) of the adapter housing.If so, readjust the black pointer (section2.2.2 on page 16) so that the sensor of theposition transmitter reaches the controlrange.Unscrew the clamp. For “Actuator stemextends” (FA), shift the pointer upwardtowards the actuator; for "Actuator stemretracts" (FE), shift the pointer downwardtowards the valve. For valves with rod-typeyoke, slightly shift the positioner on the rodin downward (FE) or upward (FA) direction.

Note: Every time you make a change as de-scribed above, the zero point and span ofthe positioner must be readjusted before cal-ibrating the position transmitter.

6 Servicing explosion-protectedversions

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 used out-side hazardous areas and are intended forfuture 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.

Observe requirements stated inEN 60079-17: 2003 for servicing explo-sion-protected devices.
