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-
ablex)tothecontrolsignal(referencevari-
ablew).Thepositionercomparestheelectric
control signal of a control system to the travel
or opening angle of the control valve and is-
suesasignalpressure(outputvariabley)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-
pacitybooster(7)andtheelectronicswith
microcontroller (5).
Thepositioneristtedwiththreebinarycon-
tacts as standard: A fault alarm output indi-
cates a fault to the control room and two
congurablesoftwarelimitcontactsareused
to indicate the end positions of the valve.
The valve position (x) is transmitted as a ei-
theranangleofrotationortraveltothepick-
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
4to20mADCcontrolsignal(reference
variable)afterithasbeenconvertedbythe
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-
lyoverthedownstreambooster(7).This
causes the valve plug to move to the position
determinedbythereferencevariable(w).
Thesupplyairissuppliedtothebooster(7)
andthepressureregulator(8).Anintermedi-
ateowregulator(9)withxedsettingsis
used to purge the positioner and, at the
sametime,guaranteestrouble-freeoperation
ofthebooster.Theoutputsignalpressure
suppliedbytheboostercanbelimitedby
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.

Design and principle of operation
3.1 Safety function (SIL)
Thesafetyfunctionisbasedontheshutdown
of the i/p converter (6). This causes the
pneumaticactuatortobeventedandthe
valvetomovetoitsfail-safeposition.
Monitoring of the input signal
The i/p converter is switched off when the
input signal of the positioner at terminals
+11/–12fallsbelow3.8mAor4.4mAde-
pending on the positioner version (a signal
rangeof4to20mAisrequired).See
Fig.20onpage60.
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
voltageatterminals+81/–82fallsbelow
12V(aninputvoltageof24VDCisre-
quired).SeeFig.20onpage60.
Whenthei/pconverterisswitchedoffas
part of the monitoring of the input signal or
thevoltagesupply,thefail-safepositionS is
activated and is indicated on the positioner
display.
If required, the user can check the safety
function using the software.

the Operating Instructions u EB8389-1.
3.2 Valve diagnostics
The EXPERTplus valve diagnostics are inte-
grated into the positioner. They provide in-
formation on the control valve and generate
statusmessages,whichallowfaultstobe
pinpointedquickly.

3.3 Communication
The positioner is equipped with an interface
for HART®protocol(HighwayAddressable
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
20mAreferencevariable.
Either a HART®capablehandheldcommuni-
catororacomputerwithFSKmodemcanbe
usedtoestablishcommunicationandoper-
ate the positioner.
3.4 Conguration using the
TROVIS-VIEW software
ThepositionercanbeconguredwithSAM-
SON'sTROVIS-VIEWCongurationand
Operator Interface (version 4). For this pur-
pose, the positioner has a digital interface
(SSP)toallowtheRS-232orUSBportofa

Solenoid valve
If the operating voltage for the solenoid
valve(12)fallsbelow12V,thesupplypres-
surefortheboosterisventedtotheatmo-
sphere. As a result, the actuator is vented
andthecontrolvalvemovestothefail-safe
position. In manual mode, the manual set
point is reset to 0%. A different manual set
point must entered again.
