3 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 (set point w).
The input signal received from a control sys-
tem is compared to the travel or rotational
angle of the control valve, and a pneumatic
signal pressure (output variable y) is pro-
duced.
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 set point deviation occurs, the actu-
ator is pressurized or vented. If required, the
changes in the signal pressure can be
slowed down by a connectable Q 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.
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 case as well as to op-
timize 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.

The positioner communicates and is pow-
ered using IEC 61158-2 transmission tech-
nology conforming to the PROFIBUS-PA
specification.
As a standard feature, the positioner comes
with a binary input for DC voltage signals to
signalize process information over the
PROFIBUS-PA.
The extended EXPERTplus diagnostics are in-
tegrated into the positioner. They provide in-
formation on the positioner and generates
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:
4Direct attachment to SAMSON
Type 3277 Actuator: section 4.1
4Attachment to actuators according to
IEC 60534-6 (NAMUR): section 4.2

4Attachment to Type 3510 Micro-flow
Valve: section 4.4
4Attachment to rotary actuators according
to VDI/VDE 3845: section 4.5
3.1 Additional equipment
Solenoid valve
If the operating voltage for the solenoid
valve (12) fails, the supply pressure for the
booster is vented to the atmosphere. As a
result, the actuator is vented and the valve
moves to the fail-safe position.
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).
Inductive limit switch
The rotary shaft of the positioner carries an
adjustable tag which actuates the installed
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 inductive limit switch).
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 net-
work.
EB 8384-4 EN 9
Design and principle of operation

3.2 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..
The Configuration Manual KH 8384-4 EN
contains a description on how to configure
and operate the positioner over
PROFIBUS-PA.
3.2.1 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 connect
the RS-232 or USB port of the computer to
the positioner over an adapter cable.
The TROVIS-VIEW software enables the user
to easily set parameters in the positioner
and view process parameters online.
Note: The TROVIS-VIEW software is a com-
mon operator interface for various smart
SAMSON devices. The software together
with a device-specific module allow the con-
figuration and parameterization of the de-
vice.
The device-specific module for Type 3730-4
can be downloaded free of charge from the
SAMSON website (Services > Software >
TROVIS-VIEW).
Additional information on TROVIS-VIEW
(e.g. system requirements) can found on the
SAMSON website and in the Data Sheet
T 6661 EN.

NOTICE
Attach the positioner to the control valve,
observing the following instructions to avoid
damaging the positioner.
–Use only the mounting parts/accessories
listed in the Tables 1 to 7 (pages 42 to
46) to mount the positioner. Observe the
type of attachment.
–Observe the assignment between lever
and pin position (see travel tables on
page 15).
Lever and pin position
The positioner is adapted to the actuator
and to the rated travel by the lever on the
back of the positioner and the pin inserted
into the lever.
The travel tables on page 15 show the maxi-
mum adjustment range at the positioner. The
travel that can be implemented at the valve
is additionally restricted by the selected
fail-safe position and the required compres-
sion of the actuator springs.
The positioner is standard equipped with the
lever M(pin position 35).
Note: If the standard mounted lever M (pin
position 35) is replaced, the newly mounted
lever must be moved once all the way as far
as it will go in both directions to adapt it to
the internal measuring lever.

mounting parts as well as the accessories.
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 upon supply air
failure), the switchover plate (9) must first be
attached 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. 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) into the groove of
the positioner housing and the seal ring
(10.1) on the back of the housing.
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. 23).
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.
Note for all types of attachment except for
direct attachment to Type 3277-5: The sig-
nal pressure output at the back must be
sealed using the screw plug (4, order no.
0180-1254) and the associated O-ring (or-
der no. 0520-0412).
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.

mounting parts as well as the accessories
with their order numbers.
Note the travel table on page 15.
Actuators with 175 to 750 cm²
Mount the positioner on the yoke as shown
in Fig. 5. The signal pressure is routed to the
actuator over the connection block (12), for
actuators with fail-safe action "Actuator
stem extends" internally through a bore in
the valve yoke and for "Actuator stem re-
tracts" through external 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 355, 700 and
750 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 position 50 and screw tight.
For actuators 175 to 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 casing.
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. 23). 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 reposi-
tion 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 corre-
sponding 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.
