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
actuator 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)
ensures a constant air ow to the
atmosphere, which is used to ush the inside
of the positioner housing and to optimize the
air capacity 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
integrated into the positioner. They provide
information on the positioner and generate
diagnostic 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 input
Positioners can be optionally tted with a bi-
nary input.
−Connection to terminals A-B:
The binary input for DC voltage signals
allows process information to be ex-
changed over the FOUNDATION™ eld-
bus network.
−Connection to terminals B-C:
Input to connect a oating contact pow-
ered by the positioner. The switching
state of the binary input can be indicated
over the FOUNDATION™eldbus net-
work.
3.2 Communication
The positioner is controlled completely by
digital signal transmission according to
FOUNDATION™ eldbus specication.
Data are transmitted over the bus using digi-
tal, bit-synchronous Manchester coding at a
Baud rate of 31.25kbit/s over twisted-pair
wires according to IEC61158-2.
3.2.1 Conguration using the
TROVIS-VIEW software
The positioner can be congured with
SAMSON's TROVIS-VIEW Software. For this
purpose, 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.
TROVIS-VIEW can be downloaded free of
charge from our website at uwww.samson.
