NOTICE
The actuator must be commissioned only with a correctly mounted valve in place!
Self-calibration
CAUTION
Never intervene manually during self-calibration.
NOTICE
Correct calibration is only possible with valve stroke > 1.2 mm. Valve stroke < 1.2 mm
results calibration failure.
If calibration fails, the actuator performs another calibration automatically after
10 seconds.
After three failed calibration attempts, the actuator stem remains in the extended
position and the valves are closed.
