3 Design and principle of
operation
The electropneumatic positioner is mounted
to pneumatic control valves and is used to
assign the valve position (controlled
variable x) to the control signal (reference
variable w). The DC control signal received
from a control unit is compared to the travel
or rotational angle of the control valve and
issues 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
resistance, an analog i/p module with
downstream booster as well as the electronic
unit with a microcontroller. The positioner is
fitted with two adjustable software limit
switches as standard to indicate 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 output signal pressure supplied by the
booster can be limited to 2.4 bar by activat-
ing the parameter P9.
The volume restriction Q (10) is used to opti-
mize the positioner by adapting it to the ac-
tuator size.
Tight-closing function:
The pneumatic actuator is completely filled
with air or vented as soon as the reference
variable falls below 1 % or exceeds 99 %
(see end positions set over parameters P10
and P11).

4 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 actual valve travel that can be achieved
is restricted by the pin position used and ad-
ditionally by the actuator spring compres-
sion required.
The travel range listed in the travel tables
opposite can only achieved if the nominal
range is set to MAX.
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.

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

4.2 Attachment according to
IEC 60534-6
The positioner is attached to the control
valve with a NAMUR bracket (10).
Refer to Table 3 on page 31 for the required
mounting parts as well as the accessories
with their order numbers.
Note the travel table on page 13!
1. Screw the two bolts (14) to the bracket
(9.1) of the stem connector (9), place the
follower plate (3) on top and use the
screws (14.1) to tighten.
Actuator size 2800 cm² and 1400 cm² with
120 mm travel:
For a travel of 60 mm or smaller, screw the
longer follower plate (3.1) directly to the
stem connector (9). For a travel exceeding
60 mm, mount the bracket (16) first and
then the follower plate (3) to the bracket to-
gether with the bolts (14) and screws (14.1).
2. Mount NAMUR bracket (10) to the con-
trol valve as follows:
For attachment to the NAMUR rib, use
an M8 screw (11) and toothed lock
washer directly in the yoke bore.
For attachment to valves with rod-type
yokes, use two U-bolts (15) around the
yoke.
Align the NAMUR bracket (10) accord-
ing to the embossed scale so that the slot
of the follower plate (3) is centrally
aligned with the NAMUR bracket at mid
valve travel.
3. Mount connecting plate (6) or pressure
gauge bracket (7) with pressure gauges
(8) on the positioner, making sure both
seal rings (6.1) are seated properly.
4. Select required lever size (1) M,Lor XL
and pin position according to the actua-
tor size and valve travels listed in the ta-
ble below.
Should you require a pin position other
than position 35 with the standard in-
stalled lever M, or require a lever size L
or XL, proceed as follows:
5. Screw the follower pin (2) in the as-
signed lever bore (pin position) as listed
in the table. Only use the longer follower
pin (2) included in the mounting kit.
6. Place lever (1) on the positioner shaft
and screw tight using the disk spring
(1.2) and nut (1.1).
Note: If you have mounted a new lever (1),
you must move it once all the way as far as
it will go in both directions.
7. Place positioner on the NAMUR bracket
in such a manner that the follower pin
(2) rests in the slot of the follower plate
(3, 3.1). Adjust the lever (1) correspond-
ingly.
Screw the positioner to the NAMUR
bracket using both its fixing screws.
