5.7 Commissioning part-turn actuators
5.7.1 Preparing part-turn actuators for commissioning
Note
Setting of the adjustment angle
The usual adjustment angle for part-turn actuators is 90°.
● Set the transmission ratio selector in the positioner to 90°.
Condition
The following conditions must be fulfilled before activating the initialization:
1. You have installed the positioner for the part-turn actuators using the suitable mounting kit.
2. You have connected the actuator and the positioner to the pneumatic lines.
3. Pneumatic auxiliary power is supplied to the positioner.
4. The positioner has been connected to a suitable current or voltage source.
Setting the actuator
1. The positioner is in the "P manual mode". The current potentiometer voltage P in percent is shown on the upper line in
the display. "NOINI" blinks in the lower line of the display. Examples of corresponding displays are given below:
2. 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

End position
By simultaneously pressing the
3. After checking, move the actuator to a central position. This accelerates the initialization process.
5.7.2 Automatic initialization of part-turn actuators
Requirements
The following conditions must be fulfilled before activating the automatic initialization:
1. The actuating range of the actuator can be passed through completely.
2. The actuator shaft is at a central position.
