Setting the actuator
1. Check whether the mechanical unit can be moved freely in the entire travel range. Move
the actuator to the respective end position for this purpose using the

End position
By simultaneously pressing the
2. Now move the actuator to the horizontal position of the lever.
3. A value between "P48.0" and "P52.0" is shown on the display.
4. If a value beyond this value range is shown on the display, you must move the friction
clutch. Move the friction clutch until a value between "P48.0" and "P52.0" is achieved.
The closer this value is to "P50.0", the more accurately the positioner determines the
stroke travel.
Note
The following is applicable for the flameproof enclosure version:
The inner friction clutch is fixed. Therefore, only move the outer friction clutch.
