Required mounting parts and accesso-
ries: Table 4 on page 19.
Both mounting kits contain all the necessary
mounting parts. The parts for the actuator
size used must be selected from the mount-
ing kit. Prepare actuator and mount possibly
required adapter supplied by the actuator
manufacturer.
1. Mount the housing (10) onto the rotary
actuator. In case of VDI/VDE attachment,
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. For VETEC R Actuator, place on the
adapter (5.1).
Place adapter (3) onto
Type 3278, VE -
TEC S160 and VETEC R Actuators . For
VDI/VDE version , this step depends on
the actuator size.
3. Stick adhesive label (4.3) onto the
coupling 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
symbols 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
SAMSON Type 3278,
