1 Design and principle of
operation
The electropneumatic positioner is attached
to pneumatic control valves. It is used to as-
sign the valve stem position (controlled vari-
able x) to the control signal (reference vari-
able w). The input signal received from a
control system is compared to the travel or
rotational angle of the control valve, and a
pneumatic signal pressure (output vari-
able y) is produced.
The positioner consists of a travel sensor sys-
tem proportional to resistance, an analog
i/p converter with a downstream booster
and the electronics unit with microcontroller.
When a deviation occurs, the actuator is
pressurized or vented. If required, the
changes in the signal pressure can be
slowed down by a connectable Q restric-
tion. The signal pressure supplied to the ac-
tuator can be limited by software or on site
to 1.4, 2.4 or 3.7 bar.
A constant air stream to the atmosphere is
created by the flow regulator (9) with a
fixed set point. The air stream is used to
purge the inside of the housing as well as to
optimize the air capacity booster. The i/p
module (6) is supplied with a constant up-
stream pressure by the pressure regulator
(8) to make it independent of the supply air
pressure.

IEC 61158-2

The positioner communicates and is pow-
ered using IEC 61158-2 transmission tech-
nology conforming to PROFIBUS-PA specifi-
cation.
As a standard feature, the positioner comes
with a binary input for DC voltage signals to
signalize process information over the
PROFIBUS-PA.
1.1 Additional equipment
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.
NOTICE
In manual mode (MAN), the manual set
point is also reset to 0 %. A different manual
set point must be entered again (Code 1).
Version with inductive limit switch
The rotary shaft of the positioner carries an
adjustable tag which actuates the installed
proximity switch.
Version with binary contact
All positioners are fitted with a binary input
for DC voltage signals over which process
information can be issued over the
PROFIBUS-PA network.
Another optional binary input is an active
input powered by the positioner to connect
a floating contact. Its switching condition
can also be issued over the PROFIBUS-PA
network.
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).
1.2 Communication
The positioner is completely controlled over
the digital signal transmission implemented
complying with PROFIBUS-PA Profile B as
per DIN EN 50170 and DIN 19245 Part 4.
Data are transmitted as bit-synchronous cur-
rent modulation at a rate of 31.25 kbit/s
over twisted-pair cables conforming to
IEC 61158-2.
Usually, the positioner settings are made on
a computer which is connected to one or
more positioners linked over a segment cou-
pler to the PROFIBUS segment of the com-
puter.
Configuration using TROVIS-VIEW software
The positioner can be configured using
TROVIS-VIEW Configuration and Operator
Interface software.
The positioner is equipped with an addi-
tional digital SERIAL INTERFACE to allow a
computer to be connected over an adapter
cable from the RS-232 interface of the com-
puter to the positioner.
The TROVIS-VIEW software enables the user
to easily set parameters in the positioner
and view process parameters online.

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 standard 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.

2.1 Direct attachment
2.1.1 Type 3277-5 Actuator
Refer to Table 1 on page 16 for the required
mounting parts as well as the accessories
with their order numbers.
Note the travel table on page 15!
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 vent plug (4) on the back of the
positioner and close the signal pressure
output "Output 38" on the connecting
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. 4, left) point-
ing towards the signal pressure connec-
tion. 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, reposition 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)
in such a manner 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. 18).
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
cover 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
Refer to Table 2 on page 16 or the required
mounting parts as well as the accessories
with their order numbers.
Note the 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, on the
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 position
35, reposition it in the bore for pin posi-
tion 50 and screw tight.
For actuators 240 and 350 cm² with
15 mm travel, the follower pin (2) re-
mains in pin position 35.
4. Insert formed seal (15) in the groove of
the positioner housing.
5. Place positioner on the cover plate in
such a manner 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. 18). 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.
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.
