Mounting and start-up
place spacers (11) underneath, if neces-
sary.
2. For SAMSON Type 3278 and VETEC
S160 Rotary Actuators, fasten the
adapter (5) onto the free end of the shaft
and for VETEC R Actuator, place on the
adapter (5.1). For Type 3278, VE-
TEC S160 and VETEC R Actuators, place
on the adapter (3). For VDI/VDE ver-
sion, only use the adapter when it is re-
quired due to the actuator size.
3. Stick adhesive label (4.3) onto the cou-
pling in such a manner that the yellow
part of the sticker is visible in the window
of the housing when the valve is OPEN.
Adhesive labels with explanatory sym-
bols are enclosed and can be stuck on
the enclosure, if required.

4. Fasten coupling wheel (4) on the slotted
actuator shaft or adapter (3) using screw
(4.1) and disk spring (4.2).
5. Unscrew the standard follower pin (2)
from the positioner's M lever (1). Attach
the follower pin (Ø5 mm) included in the
mounting kit to pin position 90°.
6. Mount connecting plate (6) for required
G ¼ connecting thread or pressure
gauge bracket (7) with pressure gauges
on the positioner, making sure the two
seals (6.1) are seated properly. Dou-
ble-acting springless rotary actuators re-
quire the use of a reversing amplifier on
the connection side of the positioner
housing (see section 5.9).
7. For actuators with a volume of less than
300 cm³, screw the screw restriction (or-
der no. 1400-6964) into the signal pres-
sure output of the positioner (or the out-
put of the pressure gauge bracket or con-
necting plate).
8. Place positioner on housing (10) and
screw it tight. Taking the actuator's direc-
tion of rotation into account, adjust lever
(1) so that it engages in the correct slot
with its follower pin (Fig. 23).
