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 (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 variable
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 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.

FOUNDATION
fieldbus
IEC 61158-2

The positioner communicates and is pow-
ered using IEC 61158-2 transmission tech-
nology conforming to FOUNDATION™
fieldbus specification.
As a standard feature, the positioner comes
with a binary input for DC voltage signals to
signalize process information over the
FOUNDATION™fieldbus.
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 acc. to
IEC 60534-6 (NAMUR): Section 4.2
4Attachment to Type 3510 Micro-flow
Valve: Section 4.3
4Attachment to rotary actuators acc. to
VDI/VDE 3845: Section 4.4
3.1 Application type
Two application types for the valve are
available: Control valve and Open/Close
(on/off) valve. The manual mode
(MAN) and the automatic mode (AUTO)
can be selected with both application types.
Depending on the application type that has
been selected, the positioner behaves differ-
ently in the automatic mode (AUTO) :
Control over FOUNDATION™ fieldbus is
performed over the AO Function Block (con-
trol valve) and over the DO1 Function Block
(on/off valve). The application type can be
entered in the Resource Block over the
SELECT_DO_1 parameter (see Configura-
tion Manual KH 8384-5 EN) or at the
positioner using Code 49 - h0. See section
14.
Note:
–
Depending on the application type, cer-
tain diagnostic functions cannot be per-
formed or analyzed. Refer to
EB 8389 EN on EXPERTplus valve diag-
nostics.
–
In manual mode, an on/off valve can be
moved past 100 % of the nominal range
(with the closed position for ATO) or be-
low 0 % of the nominal range (with the
closed position for ATC). See section 7.1
for the valve closed position.
3.2 Additional equipment
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).
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 inputs
Binary input BE1 (14):
The positioner has an binary input for DC
voltage signals as standard, which allows
process information to be exchanged over
the FOUNDATION™fieldbus network.
Binary input BE2 (15):
This binary input is optional. It is an active
input which connects a floating contact
which is powered by the positioner. The
switching state of the binary input can be in-
dicated over the FOUNDATION™fieldbus
network.
Note: The binary inputs are configured in
the DI Function Blocks (see Configuration
Manual KH 8384-5 EN).
3.3 Communication
The positioner is completely controlled over
the digital signal transmission implemented
according to FOUNDATION™ fieldbus spec-
ification.
Data are transmitted as bit-synchronous
current modulation at a rate of 31.25 kbit/s
over twisted-pair cables conforming to
IEC 61158-2.
Note: In the case, complex functions are
started in the positioner, which require a
long calculation time or lead to a large
quantity of data being stored in the volatile
memory of the positioner, the alert “busy” is
issued over DD.
This alert is not a fault alarm and can sim-
ply be confirmed.
The Configuration Manual KH 8384-5 EN
contains a description on how to configure
and operate the positioner over
FOUNDATION™ fieldbus.
EB 8384-5 EN 13
Design and principle of operation

3.3.1 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 3730-5
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.
3.3.2 Configuration using the
NI-FBUS™ Configurator
The NI-FBUS™ Configurator from National
Instruments can also be used to configure
the positioner. For this purpose, an interface
card must be installed in a computer to con-
nect it to the FOUNDATION™ fieldbus.
The integrated function blocks are linked us-
ing the NI-FBUS™ Configurator.

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 5 (pages 41 to
43) to mount the positioner. Observe the
type of attachment!
–
Observe the assignment between lever
and pin position (see travel tables on
page 19)!
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 19 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.

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 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. 20).
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.
