Follow the procedure (steps 1 - 3) below to attach the positioner to a rotary
actuator:
1. Mount the adapter to the positioner
2. Attach the mounting bracket (1) to the positioner
• Determine the mounting position (in paral-
lel to the actuator or shifted by 90°).
• Determine the direction of rotation of the
actuator (clockwise or counterclockwise).
• Move the rotary actuator to its home posi-
tion.
• On the basis of the mounting position, the
home position, and the direction of rotation
it must be determined in which position the
feedback shaft (1) of the positioner must
be pre-adjusted and in which position the
adapter (2) must be placed, to enable the
positioner to travel within the correct range
(the arrow on the rear of the device must
travel within the admissible range, for
details see Fig. 2 on page 11).
• Pre-adjust the feedback shaft.
• Place the adapter on the feedback shaft in
the appropriate position and fix it by set-
screws (3); ensure that one of the set-
screws is engaged on the side of the
feedback shaft with the flat.
