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.
