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
