Manual initialization of part-turn actuators

You can use this function to initialize the positioner without needing to move the actuator to
the lower and upper endstops. The lower and upper endstops of the actuator travel are set
manually. When the control parameters are optimized, the further initialization process runs
automatically.
Requirements
The following requirements must be fulfilled before activating manual initialization:
1. The positioner has been prepared for using on part-turn actuators.
2. The actuator can be moved completely.
3. The displayed potentiometer position is within the permissible range between "P5.0" and
"P95.0".
Note
Setting of the adjustment angle
The usual adjustment angle for part-turn actuators is 90°. Accordingly set the
transmission ratio selector in the positioner to 90°.
