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(setpointw).The
electricsignalfromacontrollingsystemis
comparedtothetravelortherotationalangle
ofthecontrolvalveandasignalpressure
(outputvariabley)isproducedfortheactua-
tor.
Thepositionerconsistsofatravelsensorsys-
tem(2)proportionaltoresistance,ananalog
i/pconverterwithadownstreamaircapacity
booster(7)andtheelectronicswithmicrocon-
troller(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 is transmitted as a either
anangleofrotationortraveltothepick-up
leverandtothetravelsensor(2)andsupplied

bytheA/Dconverter(4).Incaseofaset
pointdeviation,theactivationofthei/pcon-
verter(6)ischangedsothattheactuator(1)
ispressurizedorventedaccordinglyoverthe
downstreambooster(7).Asaresult,theclo-
surememberofthevalve(e.g.plug)ismoved
tothepositiondeterminedbythesetpoint.
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.
ThevolumerestrictionQ(10)isusedtoopti-
mizethepositioner.
TheextendedEXPERTplusdiagnosticsarein-
tegratedintothepositioner.Theyprovidein-
formationonthepositionerandgeneratedi-
agnosticandstatusmessages,whichallow
faultstobepinpointedquickly.
Thepositionerissuitableforthefollowing
typesofattachmentusingthecorresponding
accessories:
−DirectattachmenttoSAMSON
Type3277Actuators
−Attachmenttoactuatorsaccordingto

3.1 Additional equipment
Solenoid valve
Iftheoperatingvoltageforthesolenoid
valve(12)fails,thesignalpressureforthe
boosterisventedtotheatmosphere.Asare-
sult,theactuatorisventedandthevalve
movestoitsfail-safeposition.
NOTICE
The manual set point is automatically
reset to 0% after the solenoid valve is
activated.
A different manual set point must be
entered again (Code 1).
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independentofthe
positioner’sinputsignal(minimumcurrent
3.8mA),themomentarytravel/angleofro-
tationiscontrolledinreal-time.Additionally,
the position transmitter allows positioner
faultstobeindicatedoverasignalcurrentof
<2.4mAor>21.6mA.
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.

12 EB 8384-3 EN
Design and principle of operation
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(onlywithoutinduc-
tivelimitcontact).
Analog input x
The analog input x option allows commer-
ciallyavailableexternallinearorangleposi-
tionsensorsthatusea4to20mAsignalto
beconnectedtothepositioner.Theanalog
inputxisprotectedagainstreversepolarity
andoverloadupto24VAC/DC.Theposi-
tionerswitchestoopen-loopoperation(no
closed-loopoperation)assoonastheinput
signalfallsbelow2.5mA.
Leakage sensor
Byupgradingthepositionerwithaleakage
sensor,itispossibletodetectseatleakage
when the valve is in the closed position.
Binary input
Positionerscanbeoptionallyttedwithabi-
naryinput.Thefollowingactionscanbetrig-
geredbychangingtheedgestate:
−Transmit switching state[default]
Theswitchingstateofthebinaryinputis
logged.
−Set on-site operation write protection
Whilethebinaryinputisactive,noset-
tingscanbechangedatthepositioner.
EnablingcongurationoverCode3is
not active.
−Switch between AUTO/MAN
Thepositionerchangesfromtheauto-
matic mode (AUTO)tothemanual
mode (MAN)orviceversa.
Thisfunctionisnotperformediftheposi-
tionerisinthefail-safepositionmode
(SAFE).
−VariousdiagnosticfunctionsuEB8389
(EXPERTplusvalvediagnostics)
Note:
−The optional binary input can only
be congured using the
TROVIS-VIEW software and using
the DD parameters (uEB8389 on
EXPERTplus valve diagnostics).
−The default switching state is with
an open switch.
3.2 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setpoint.
Either a HART®capablehandheldcommuni-
catororacomputerwithFSKmodemcanbe
usedtoestablishcommunicationandoper-
ate the positioner.

Thepositionercanbeconguredwith
SAMSON'sTROVIS-VIEWConguration

Thepositionerhasforthispurposeaserial

Attachment to the control valve – Mounting parts and accessories
4 Attachment to the control
valve – Mounting parts and
accessories
NOTICE
Risk of malfunction due to incorrect
sequence of mounting, installation
and start-up!
Keep the following sequence.
1. Remove the protective lm from the
pneumatic connections.
2. Mount the positioner on the control
valve.
3.
Connect the supply air.
4. Connect the electrical power.
5. Perform the start-up settings.
Thepositionerissuitableforthefollowing
typesofattachment:
−DirectattachmenttoSAMSON
Type3277Actuator
−Attachmenttoactuatorsaccordingto
IEC60534-6(NAMUR)
−AttachmentaccordingtoVDI/VDE3847
−AttachmenttoType3510Micro-ow
Valve
−Attachment to rotary actuators
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21).
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21showthe
maximumadjustmentrangeattheposition-
er.Thetravelthatcanbeimplementedatthe
valveisadditionallyrestrictedbytheselected
fail-safepositionandtherequiredcompres-
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.
Travel tables
Note:
The Mlever is included in the scope of delivery.
S, L, XL levers for attachment according to IEC60534-6 (NAMUR) are available as
