Mounting and start-up
2. For SAMSON Type3278 and VETEC
S160 Rotary Actuators, screw the adapt-
er (5) onto the free end of the shaft or
place adapter (5.1) onto the shaft of the
VETEC R Actuator. Place adapter (3) on-
to Type3278, VETEC S160 and VETEC R
Actuators. For VDI/VDE version, this
step depends on 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).
Attachthefollowerpin(Ø5mm)includ-
ed in the mounting kit to pin position
90°.
6. Mount connecting plate (6) for required
G¼connectingthreadorpressure
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-
quiretheuseofareversingamplieron
the connection side of the positioner
housing(seesection5.9).
7. For actuators with a volume of less than
300cm³,ttherestriction(orderno.
1400-6964) into the signal pressure out-
put of the positioner (or the output of the
pressure gauge bracket or connecting
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
withitsfollowerpin(Fig.22).
