1. Move the carrier pin on the lever. Select the scale position equal to the nominal stroke or a next-higher position.
2. Tighten the carrier pin using the M6 hexagon nut.
Connecting the positioner
1. Connect a suitable current or voltage source. The positioner is now in the "P manual mode". The current potentiometer
voltage (P) in percent is shown in the upper line of the display, e.g.: "P12.3", and "NOINI" blinks in the lower line:
2. Connect the actuator and the positioner to the pneumatic lines.
3. Supply the pneumatic auxiliary power to the positioner.
Setting the actuator
1. Check whether the mechanical unit can be moved freely in the entire actuating range. Move the drive to the respective
end position for this purpose using 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.
