1 Design and principle of oper-
ation
The electropneumatic positioner is mounted
to pneumatic control valves and is used to
assign the valve position (controlled vari-
able x) to the control signal (reference vari-
able w). The DC control signal received from
a control unit is compared to the travel or
rotational angle of the control valve and is-
sues a signal pressure (output variable y).
The positioner is designed depending on the
corresponding accessories for direct attach-
ment to Type 3277 Actuators or for attach-
ment to actuators according to IEC 60534-6
(NAMUR).
Additionally, a coupling wheel included in
the accessories is required to transfer the ro-
tary motion for rotary actuators according to
VDI/VDE 3845.
Springless rotary actuators require an ac-
cessory reversing amplifier to permit the
powered operation in either direction.
The positioner basically consists of a travel
sensor system that functions proportional to
the resistance, an analog i/p module with
downstream booster as well as the electronic
unit with a microcontroller.
The positioner is fitted with three binary con-
tacts as standard: A fault alarm output is
used to indicate a fault to the control station;
two configurable software limit switches in-
dicate the valve’s end positions.
The position of the valve is transmitted as
linear travel motion or angle of rotation via
pick-up lever and travel sensor (2) to an an-
alog PD controller (3). Simultaneously, an
A/D converter (4) transmits the position of
the valve to the microcontroller (5). The PD
controller 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 system deviation, the operation
of the i/p converter (6) is changed so that
the actuator (1) is filled or vented via the
downstream air capacity booster (7). This
causes the closure member of the control
valve to move to the position determined by
the reference variable.
The pneumatic air capacity booster (7) and
the pressure regulator (8) are provided with
supply air. An intermediate flow regulator
(9) with fixed settings is used to purge the
positioner and also guarantees trouble-free
operation of the pneumatic booster. The out-
put signal pressure supplied by the booster
can be limited over the software.
The volume restriction Q (10) is used to opti-
mize the positioner by adapting it to the ac-
tuator size.
Serial Interface
The positioner is equipped with an interface
to allow the SAMSON TROVIS-VIEW Con-
figuration and Operator Interface software
to transmit data and parameters over an
adapter cable from the RS-232 interface of
a computer to the positioner. Refer to sec-
tion 13.
To detect any valve faults at an early stage,
the positioner can optionally be equipped
with EXPERT+valve diagnostics. You can ac-
cess the functions provided by EXPERT+
valve diagnostics over TROVIS-VIEW soft-
ware and over the DTM file of the device.
8EB 8384-2 EN
Design and principle of operation

Refer to Data Sheet T 8388 EN for more de-
tails on EXPERT+valve diagnostics. Instruc-
tions on how to operate the software can be
found in Mounting and Operating Instruc-
tions EB 8388 EN.
1.1 Additional equipment
As an option, the device can be additionally
equipped with a solenoid valve for forced
venting, an analog position transmitter, an
inductive limit switch or an external position
sensor.
Version with solenoid valve
If the operating voltage for the solenoid
valve (12) fails, the supply pressure for the
i/p module 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, independent of
the reference variable.
Version with position transmitter
The position transmitter (13) is a two-wire
transmitter and issues the travel sensor sig-
nal as a 4 to 20 mA signal processed by the
microcontroller.

Since this signal is issued independent of the
positioner’s input signal (min. current
3.8 mA), the actual travel/angle of rotation
is controlled in real-time. Additionally, the
position transmitter provides the possibility
of signaling a positioner fault over a signal
current of <2.4 mA or >21.6 mA.
Version with inductive limit switch
The rotary shaft of the positioner carries an
adjustable tag which actuates the installed
proximity switch.
The optional inductive limit switch (11) leads
to A1 and the software limit switch, which
remains in operation, leads to A2.
Version with 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 via cable and piping for
air (only without inductive limit switch).

2 Attachment to the control
valve – mounting parts and
accessories
The positioner can be attached either di-
rectly to a SAMSON Type 3277 Actuator or
according to IEC 60534-6 (NAMUR) to con-
trol valves with cast yokes or rod-type yokes
as well as to rotary actuators according to
VDI/VDE 3845.
For attachment to the various actuators, cor-
responding mounting parts and accessories
are required. These are listed with their or-
der numbers in Tables 1 to 5.
On attaching the positioner, it is important
to observe the assignment between lever
and pin position according to the travels
listed in the travel tables.
The tables show the maximum adjustment
range at the positioner. The travel that can
be implemented at the valve is restricted by
the pin position used and additionally by the
actuator spring compression required.
The positioner is by default equipped with
the lever M(pin position 35).
Note!
If the standard mounted lever M (pin posi-
tion 35) is replaced, the newly mounted le-
ver must be moved once all the way as far
as it will go in both directions to adapt it to
the internal measuring lever.

Actuator with 120 cm²
Depending on the type of positioner attach-
ment, the signal pressure is routed either left
or right of the yoke through a bore to the
actuator diaphragm. Depending on the
fail-safe action of the actuator "Actuator
stem extends" or "Actuator stem retracts"
(valve closes or opens if the supply air fails),
the switchover plate (9) must first be at-
tached to the actuator yoke. Align the
switchover plate with the corresponding
symbol for left or right attachment according
to the marking (view looking onto the
switchover plate).
1. Mount connecting plate (6) or pressure
gauge bracket (7) with pressure gauges
onto the positioner, making sure both
seal rings (6.1) are seated properly.
2. Remove screw plug (4) on the back of
the positioner and close the signal pres-
sure output "Output 38" on the connect-
ing plate (6) or on the pressure gauge
bracket (7) with the stopper (5) included
in the accessories.
3. Place follower clamp (3) on the actuator
stem, align and screw tight so that the
mounting screw is located in the groove
of the actuator stem.
4. Mount cover plate (10) with narrow side
of the cut-out opening (Fig. xx, on the
left) pointing towards the signal pressure
connection. Make sure that the bonded
gasket (14) points towards the actuator
yoke.
5. 15 mm travel: Keep the follower pin (2)
at lever M(1) on the back of the
positioner in the pin position 35 (deliv-
ered state).
7.5 mm travel: Remove the follower
pin (2) from the pin position 35, reposi-
tion it in the bore for pin position 25
and screw tight.
6. Insert formed seal (15) in the groove of
the positioner casing.
7. Place positioner on the cover plate (10)
so that the follower pin (2) rests on the
top of the follower clamp (3). Adjust the
lever (1) correspondingly and open the
positioner cover to hold the positioner
shaft in position at the cap or the switch
(Fig. xx).
The lever (1) must rest on the follower
clamp with spring force.
Mount the positioner on the cover
plate (10) using the two fixing screws.
During the installation make sure that
the seal ring (10.1) is inserted in the
bore of the intermediate plate.
8. Mount cover (11) on the other side.
Make sure that the vent plug points
downwards when the control valve is in-
stalled to allow any condensed water
that collects to drain off.

2.1.2 Type 3277 Actuator
For the required mounting parts and acces-
sories with their order numbers, refer to Ta-
ble 2 on page 16.
Observe travel table on page 15!
Actuators with 240 to 700 cm²
The positioner can be mounted either on the
left or on the right side of the yoke. The sig-
nal pressure is routed to the actuator over
the connection block (12), for actuators with
fail-safe action “Actuator stem extends” in-
ternally through a bore in the valve yoke
and for “Actuator stem retracts” through ex-
ternal piping.
1. Place follower clamp (3) on the actuator
stem, align and screw tight so that the
mounting screw is located in the groove
of the actuator stem.
2. Mount cover plate (10) with narrow side
of the cut-out opening (Fig. 5, left)
pointing towards the signal pressure
connection. Make sure that the bonded
gasket (14) points towards the actuator
yoke.
3. For actuators with 700 cm², remove the
follower pin (2) at lever M(1) on the
back of the positioner from pin posi-
tion 35, reposition it in the bore for pin
position 50 and screw tight.
For actuators 240 and 350 cm² with 15
mm travel, the follower pin (2) remains
in pin position 35.
4. Insert formed seal (15) in the groove of
the positioner casing.
5. Place positioner on the cover plate so
that the follower pin (2) rests on the top
of the follower clamp (3). Adjust the le-
ver (1) correspondingly and open the
positioner cover to hold the positioner
shaft in position at the cap or the switch
(Fig. ). The lever (1) must rest on the fol-
lower clamp with spring force. Mount
the positioner on the cover plate (10) us-
ing the two fixing screws.
6. Make sure that the tip of the gasket (16)
projecting from the side of the connec-
tion block (12) is positioned above the
actuator symbol that corresponds with
the actuator with fail-safe action “actua-
tor stem extends" or “Actuator stem re-
tracts.” If necessary, remove the three
fixing screws and the cover. Then repo-
sition the gasket (16) turned by 180°.
The previous version of the connection
block (Fig. 5, bottom) requires the switch
plate (13) to be turned such that the cor-
responding actuator symbol points to the
marking.
7. Place the connection block (12) with the
associated seal rings against the
positioner and the actuator yoke. Screw
it tight using the fixing screw (12.1). For
actuators with fail-safe action “Actuator
stem retracts", additionally remove the
stopper (12.2) and fit on the external
signal pressure piping.
8. Mount cover (11) on the other side.
Make sure that the vent plug points
downwards when the control valve is in-
stalled to allow any condensed water
that collects to drain off.
