−Anyhazardsthatcouldbecausedinthevalvebytheprocessmedium,thesignalpres-
sureorbymovingpartsaretobepreventedbytakingappropriateprecautions.
−Ifinadmissiblemotionsorforcesareproducedinthepneumaticactuatorasaresultof
thesupplypressurelevel,itmustberestrictedusingasuitablesupplypressurereducing
station.
To avoid damage to any equipment, the following also applies:
−Donotoperatethepositionerwiththebackofthepositioner/ventopeningfacingup-
wards.Theventopeningmustnotbesealedwhenthepositionerisinstalledonsite.
Vent opening
−Propershippingandstorageareassumed.
−Donotgroundelectricweldingequipmentneartothepositioner.
Note:

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variable
x)tothecontrolsignal(setpointw).Thepo-
sitioner compares the electric control signal
ofacontrolsystemtothetraveloropening
angleofthecontrolvalveandissuesasignal
pressure(outputvariabley)forthepneumat-
ic actuator.
The positioner is designed depending on
whichaccessoriesareselectedeitherfordi-
rectattachmenttoSAMSONType3277Ac-
tuatorsorforattachmenttoactuatorsac-
cordingtoNAMUR(IEC60534-6).
Additionally,acouplingwheelincludedin
theaccessoriesisrequiredtotransferthero-
tarymotionforrotaryactuatorsaccordingto
VDI/VDE3845.
Springlessrotaryactuatorsrequirearevers-
ingamplierincludedintheaccessoriesto
permit the powered operation in either di-
rection.
Thepositionerconsistsofatravelsensorsys-
temproportionaltoresistance,ananalog
i/p converter with a downstream air capaci-
tyboosterandtheelectronicswithmicrocon-
troller.Thepositioneristtedwithtwoad-
justablesoftwarelimitcontactsasstandard
to indicate the valve's end positions.
Thepositionofthevalvestemistransmitted
asaeitheranangleofrotationortravel
overthepick-uplevertothetravelsensor(2)
andsuppliedtoananalogPDcontroller(3).
AnA/Dconverter(4)transmitstheposition
ofthevalvetothemicrocontroller(5).
ThePDcontroller(3)comparesthisactual
positiontothe4to20mADCcontrolsignal
afterithasbeenconvertedbytheA/Dcon-
verter(4).
Incaseofasystemdeviation,theactivation
ofthei/pmodule(6)ischangedsothatthe
actuatorofthecontrolvalve(1)ispressur-
izedorventedaccordinglyoverthedown-
streambooster(7).Thiscausesthevalve
plugtomovetothepositiondeterminedby
the set point.
Thesupplyairissuppliedtotheboosterand
thepressureregulator(8).Anintermediate
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to2.4barbyactivat-
ingtheP9parameter.
Thevolumerestriction(10)isusedtoopti-
mizethepositionerbyadaptingittotheac-
tuatorsize.
Tight-closing function:
Thepneumaticactuatoriscompletelylled
with air or vented as soon as the set point
fallsbelow1%orexceeds99%(seeend
positionfunctioninP10andP11parame-
ters).

NOTICE
Risk of malfunction due to incorrect
mounting parts/accessories or incor-
rect assignment of lever and pin posi-
tion.
Attach the positioner to the control
valve only using the mounting parts
and accessories as specied in Ta-
ble1 to Table6. Observe the type of
attachment.
Observe the assignment between le-
ver and pin position (see travel tables
on page15).
Lever and pin position
The positioner is adapted to the actuator
andtotheratedtravelbytheleveronthe
backofthepositionerandthepininserted
into the lever.
Thetraveltablesonpage15showthe

sionoftheactuatorsprings.
ThepositionerisequippedwiththeMlever
(pinposition35)asstandard.
Fig.2: M lever with pin position 35
NOTICE
Risk of malfunction because the
newly mounted lever has not been
adapted to the internal measuring le-
ver.
Move the newly mounted lever (1)
once all the way as far as it will go in
both directions.
