The usual adjustment angle for part

-turn actuators is 90°.

• Set the transmission ratio selector in the positioner to 90°.

Requirements

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:

End position

By simultaneously pressing the

and buttons, you reach the end position faster.

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 travel range of the actuator can be passed through completely.

2. The actuator shaft is at a central position.
