Design and principle of operation

3 Design and principle of oper-

ation

The electropneumatic positioner is mounted

on pneumatic control valves and is used to

assign the valve position (controlled vari-

ablex)tothecontrolsignal(referencevari-

ablew).Thepositionercomparestheelectric

control signal of a control system to the travel

or opening angle of the control valve and is-

suesasignalpressure(outputvariabley)for

the pneumatic actuator.

The positioner consists of a travel sensor sys-

tem (2) proportional to resistance, an analog

i/p converter (6) with a downstream air ca-

pacitybooster(7)andtheelectronicswith

microcontroller (5).

Thepositioneristtedwiththreebinarycon-

tacts as standard: A fault alarm output indi-

cates a fault to the control room and two

congurablesoftwarelimitcontactsareused

to indicate the end positions of the valve.

The valve position (x) is transmitted as a ei-

theranangleofrotationortraveltothepick-

up lever and to the travel sensor (2) and sup-

plied to an analog PD controller. An A/D

converter (4) transmits the position of the

valve to the microcontroller (5). The PD con-

troller (3) compares this actual position to the

4to20mADCcontrolsignal(reference

variable)afterithasbeenconvertedbythe

A/D converter (4). In case of a set point de-

viation, the activation of the i/p converter (6)

is changed so that the actuator of the control

valve (1) is pressurized or vented according-

lyoverthedownstreambooster(7).This

causes the valve plug to move to the position

determinedbythereferencevariable(w).

Thesupplyairissuppliedtothebooster(7)

andthepressureregulator(8).Anintermedi-

ateowregulator(9)withxedsettingsis

used to purge the positioner and, at the

sametime,guaranteestrouble-freeoperation

ofthebooster.Theoutputsignalpressure

suppliedbytheboostercanbelimitedby

software. Both pressure sensors (23 and 24)

monitors the supply pressure ps and the sig-

nal pressure pout.

The volume restriction Q (10) is used to opti-

mize the positioner.

Thepositionerissuitableforthefollowing

types of attachment using the corresponding

accessories:

−DirectattachmenttoSAMSON

−Attachment to actuators according to IEC

Design and principle of operation

3.1 Safety function (SIL)

Thesafetyfunctionisbasedontheshutdown

of the i/p converter (6). This causes the

pneumaticactuatortobeventedandthe

valvetomovetoitsfail-safeposition.

Monitoring of the input signal

The i/p converter is switched off when the

input signal of the positioner at terminals

+11/–12fallsbelow3.8mAor4.4mAde-

pending on the positioner version (a signal

rangeof4to20mAisrequired).See

Fig.20onpage60.

Monitoring the voltage supply

(version with forced venting and solenoid

valve

The i/p converter and the solenoid valve

(when installed) are shut down whenever the

voltageatterminals+81/–82fallsbelow

12V(aninputvoltageof24VDCisre-

quired).SeeFig.20onpage60.

Whenthei/pconverterisswitchedoffas

part of the monitoring of the input signal or

thevoltagesupply,thefail-safepositionS is

activated and is indicated on the positioner

display.

If required, the user can check the safety

function using the software.

Details on EXPERTplus Valve Diagnostics in

the Operating Instructions u EB8389-1.

3.2 Valve diagnostics

The EXPERTplus valve diagnostics are inte-

grated into the positioner. They provide in-

formation on the control valve and generate

statusmessages,whichallowfaultstobe

pinpointedquickly.

3.3 Communication

The positioner is equipped with an interface

for HART®protocol(HighwayAddressable

Remote Transducer) for communication pur-

poses. Data are transmitted in a superim-

posed frequency (FSK = Frequency Shift Key-

ing) on the existing signal loop for the 4 to

20mAreferencevariable.

Either a HART®capablehandheldcommuni-

catororacomputerwithFSKmodemcanbe

usedtoestablishcommunicationandoper-

ate the positioner.

3.4 Conguration using the

TROVIS-VIEW software

ThepositionercanbeconguredwithSAM-

SON'sTROVIS-VIEWCongurationand

Operator Interface (version 4). For this pur-

pose, the positioner has a digital interface

(SSP)toallowtheRS-232orUSBportofa

computertobeconnectedtoitoveran

adaptercable.

TheTROVIS-VIEWsoftwareenablestheuser

toeasilycongurethepositioneraswellas

view process parameters online.

Note:

TROVIS-VIEW can be downloaded

free of charge from our website at

3.5 Additional equipment

Inductive limit contact

In this version, the rotary shaft of the posi-

tionercarriesanadjustabletagwhichactu-

atesthebuilt-inproximityswitch.Theoption-

al inductive contact (11) is connected to A1,

while the remaining software limit contact is

connected to A2.

Solenoid valve

If the operating voltage for the solenoid

valve(12)fallsbelow12V,thesupplypres-

surefortheboosterisventedtotheatmo-

sphere. As a result, the actuator is vented

andthecontrolvalvemovestothefail-safe

position. In manual mode, the manual set

point is reset to 0%. A different manual set

point must entered again.

Forced venting

Ifthevoltagesignalatterminals+81/–82

fallsbelow12V,thei/pconverter(6)is

de-energized.Thepositionerventstheactua-

tor,causingvalvetomovetothefail-safepo-

sitiondeterminedbytheactuator,indepen-

dentofthereferencevariable.

Analog position transmitter

Thepositiontransmitter(13)isatwo-wire

transmitter and issues the travel sensor signal

asa4to20mAsignalprocessedbythemi-

crocontroller. Since this signal is issued inde-

pendent of the positioner’s input signal, the

momentary travel/angle of rotation is con-

trolledinreal-time.Additionally,theposition

transmitterallowspositionerfaultstobeindi-

By selecting a certain function, one of the

followingactionscanbeactivated:

−Transmit switching state

Theswitchingstateofthebinaryinputis

logged.

−Activate local write protection

Aftertherstinitialization,alocalwrite

−SwitchAUTO/MAN

This function is not performed if the posi-

tionerisinthefail-safepositionmode

Additionally, the external solenoid valve

functioncanbeselectedifanon-oating

contactiscongured:

−External solenoid valve

The voltage for an external solenoid

valve is connected in parallel to terminals

+31/–32.Thisallowstheswitchingstate

ofthesolenoidvalvetobemonitored.

Note:

The optional binary input can only

be congured using the operator

software e.g. TROVIS-VIEW. The

switching state is transmitted when

the switch is closed by default.

External position sensor

In this version, only the sensor is mounted to

the control valve. The positioner is located

separately from the valve. The connection of

xandysignalstothevalveisestablishedby

cableandpipingforair.
