9.3.3 Manual initialization of part-turn actuators

You can use this function to initialize the positioner without needing to move the actuator to

the end stops. The start and end positions of the actuator travel are set manually. When the

control parameters are optimized, the further initialization process runs automatically.

Conditions

The following conditions must be fulfilled before activating the manual initialization:

1. The positioner has been prepared for using on linear actuators.

2. The actuator can be moved completely.

3. The displayed potentiometer position is within the permissible range between "P5.0" and

"P95.0".

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°.

Initializing the positioner manually

1. Switch to the "Configuration" mode. To do this, press the operating mode button for at

least 5 seconds. The following is shown on the digital display:

1 2 ... 118 119 120 121 122 123 124 125 126 127 128 ... 241 242
