on the
positioner
• four M5 screws each

Figure 17: Mounting the adapter on the positioner
1. Determine the mounting position (parallel to actuator or at
90° angle)
2. Calculate the rotational direction of the actuator (right or
left).
3. Move the part-turn actuator into the home position.
4. Pre-adjust feedback shaft.
In order for the positioner to work within the working range
(see
General on page 38), the installation position as well as
the basic position and direction of rotation of the actuator
when determining the adapter position on the axis
1
should be considered. For this purpose, the axis can be
adjusted by hand to set the adapter
3
accordingly in the
correct position.
5. Place the adapter in the suited position on the axle and
secure with threaded spuds
2
. One of the threaded pins
must be locked in place on the flat side of the feedback shaft.
