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 psand 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
Type3277Actuator
−Attachment to actuators according to IEC
60534-6(NAMUR)
−AttachmentaccordingtoVDI/VDE3847
−AttachmenttoType3510Micro-ow

−Attachment to rotary actuators acc. to

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Sis
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.
Details on EXPERTplus Valve Diagnostics in
the Operating Instructions u EB8389-1.

Design and principle of operation
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
http:\\www.samson.de > Services >
Software > TROVIS-VIEW.
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-


Design and principle of operation
catedoverasignalcurrentof<2.4mAor
>21.6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. De-
tailsonEXPERTplusValveDiagnosticsinthe
Operating Instructions uEB8389-1.
Binary input
Theoptionalbinaryinputcanbecongured:
−Toconnectaoatingcontact
−Toconnectanon-oatingcontact(0to
24VDC)
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
protectioncanbeactivated.
Whilethebinaryinputisactive,noset-
tingscanbechangedatthepositioner.
Thepositionercannotbere-initialized.
EnablingcongurationoverCode3is
not active ( ).
−Switch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
DetailsonEXPERTplusValveDiagnostics
in the Operating Instructions
uEB8389-1.
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.
