Design and principle of operation
3 Design and principle of oper-
ation
The positioner is mounted on pneumatic con-
trol valves and is used to assign the valve
position (controlled variablex) to the control
signal (set pointw). The positioner compares
the control signal of a control system to the
travel or rotational angle of the control valve
and issues a signal pressure (output vari-
abley) for the pneumatic actuator.
The positioner mainly consists of an electric
travel sensor system, an analog i/p convert-
er with a downstream air capacity booster
and the electronics with the microcontroller.
When a system deviation occurs, the actua-
tor is either vented or lled with air. If neces-
sary, the signal pressure change can be
slowed down by a volume restriction. 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 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. The i/p
converter is supplied with a constant up-
stream pressure by the pressure regulator to
compensate for any uctuations in the supply
pressure.

Design and principle of operation
The positioner communicates and is powered
using IEC61158-2 transmission technology
conforming to PROFIBUS-PA specications.
As a standard feature, the positioner comes
with a binary input for DC voltage signals to
signalize process information over the
PROFIBUS-PA network.
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:
−Direct attachment to SAMSON
Type3277 Actuators
−Attachment to actuators according to
IEC60534-6 (NAMUR)
−Attachment according to VDI/VDE3847
−Attachment to Type3510 Micro-ow
Valve
−Attachment to rotary actuators according
to VDI/VDE3845
3.1 Additional equipment
Solenoid valve
If the voltage supply for the solenoid valve
(12) fails, the supply pressure for the i/p
converter is vented to the atmosphere. The
positioner can no longer operate and the
control valve moves to the fail-safe position
determined by the actuator, regardless of the
set point.
The manual set point is also reset to 0 % af-
ter the solenoid valve is activated!
A different manual set point must be entered
again (Code 1).
Inductive limit switch
In this version, the rotary shaft of the posi-
tioner carries an adjustable tag which actu-
ates the built-in proximity switch.
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 (only without induc-
tive limit switch).
Binary input BI1
As a standard feature, the positioner comes
with a binary input for DC voltage signals to
signalize process information over the
PROFIBUS-PA network.
Binary input BI2
This binary input BI2 is optional. It is an ac-
tive input which is powered by the positioner
to connect a oating contact. The switching
state of the oating contact can be indicated
over the PROFIBUS-PA network.
