SAMSON'sTROVIS3731-3Positionerismountedonpneumaticcontrolvalvesandisused
to assign the valve position to the control signal. The device is designed to operate under ex-
actlydenedconditions(e.g.operatingpressure,temperature).Therefore,operatorsmusten-
sure that the positioner is only used in applications where the operating conditions corre-
spond to the technical data. In case operators intend to use the positioner in other applica-
tionsorconditionsthanspecied,contactSAMSON.

damage, plant operators and operating personnel must prevent hazards that could be
caused in the control valve by the process medium, the operating pressure, the signal pres-
sure or by moving parts by taking appropriate precautions. They must observe all hazard
statements, warning and caution notes in these mounting and operating instructions, espe-
cially for installation, start-up and service work.
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.
Responsibilities of the operator
The operator is responsible for proper operation and compliance with the safety regulations.
Operators are obliged to provide these mounting and operating instructions to the operating
personnel and to instruct them in proper operation. Furthermore, the operator must ensure
that operating personnel or third persons are not exposed to any danger.
Responsibilities of operating personnel

Design and principle of operation
3 Design and principle of oper-
ation
ÎRefertoFig.1
TheelectropneumaticExd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 positioner compares the electric control
signal of a control system to the travel or ro-
tational angle of the control valve and issues
asignalpressure(outputvariabley)forthe
pneumatic actuator.
The positioner consists of an electric travel
sensorsystem(2),ananalogi/pconverter
(6) with a downstream air capacity booster
(7) and the electronics with microcontroller
(5).
Whenasetpointdeviationoccurs,theactu-
atoriseitherventedorlledwithair.The
signal pressure supplied to the actuator can
be limited by software or on site to 1.4, 2.4
or3.7bar.Thexedowregulator(9)en-
suresaconstantairowtotheatmosphere,
whichisusedtoushtheinsideoftheposi-
tioner housing and to optimize the air ca-
pacitybooster(7).Thei/pconverter(6)is
supplied with a constant upstream pressure
by the pressure regulator (8) to compensate
foranyuctuationsinthesupplypressure.
AllpartsareenclosedinanExdenclosure.
The electrical connection is established over
a separate terminal compartment also with
Exdprotection.
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:

Design and principle of operation
3.1 Additional equipment
Forced venting
Thei/pconverterisde-energizedwhenno
operating voltage is applied to the corre-
sponding terminals. The positioner can no
longer operate and the control valve moves
to the fail-safe position (SAFE) determined
by the actuator, regardless of the set point.
Binary contact
The positioner has three internal binary sig-
nals which can be analyzed over terminals
A/B/C.Twoofthesesignalsareintended
for the valve end positions and one signal
for a collective fault alarm. The assignment
ofthesesignalstotheA/B/Cterminalsis
determinedoverCode25.
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 (mini-
mumcurrent3.8mA),themomentarytrav-
el/angleofrotationiscontrolledinreal-time.
Additionally, the position transmitter allows
positioner faults to be indicated over a sig-
nalcurrentof2.4mAor21.6mA.
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3is
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 positioner is in the fail-
safe position mode (SAFE).
−Various diagnostic functions uEB8389
(EXPERTplus valve diagnostics)
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 de-
fault switching state is with an open switch.
Connection to terminals A-B:
binary input for DC voltage signals
Connection to terminals B-C:
contact input for an external contact
Note

18 EB 8387-3 EN
Design and principle of operation
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 communicator or a computer with
FSK modem can be used to establish com-
munication and operate the positioner.
3.2.1 Conguration using the
TROVIS-VIEW software
ThepositionercanbeconguredwithSAM-
SON'sTROVIS-VIEWSoftware.Forthispur-
pose, the positioner has a digital interface
(SSP) to allow the USB port of a computer to
be connected to it using an adapter cable.
TheTROVIS-VIEWsoftwareenablestheuser
toeasilycongurethepositioneraswellas
view process parameters online.
