9.4.1
Preparing part-turn actuators for commissioning
NOTICE
Setting of the adjustment angle
The usual adjustment angle for part-turn actuators is 90°. Accordingly 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
