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
or button.
Note
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.
