Setting the actuator
1. Check whether the mechanical unit can be moved freely in the entire actuating range.
Move the actuator to the respective end position using the
and buttons. Press both
the direction buttons simultaneously to reach the end position faster.
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 the value is to "P50.0", the more accurate is the stroke travel determined by
the positioner.
NOTICE
The following is applicable for the flameproof enclosure version:
The inner friction clutch is fixed. Therefore, only move the outer friction clutch.

9.2.2 Automatic initialization of linear actuators
Conditions
The following conditions must be fulfilled before activating the automatic initialization:
1. The actuator spindle can be moved completely.
2. The actuator spindle is at a central position after moving.
Initializing the positioner automatically
Note
An ongoing initialization can be interrupted at any time. Press the
operating mode button
for this purpose. The settings configured until then are retained.
All parameters are reset to factory settings only if you have explicitly activated the preset
settings in the "PRST" parameter.
