Orientation
Commissioning
When commissioning, check both wiring and functioning of the actuator.
●
Actuator stem extends
●
Actuator stem retracts
The actuator must be commissioned only with a correctly mounted valve in place!
Self-calibration
When operating voltage is applied, the actuator self-calibrates (fully retracted ➙ fully
extended ➙ setpoint).
Fully retracted
Fully extended
Never intervene manually during self-calibration.
●
Correct calibration is only possible with valve stroke > 0.05 inch (1.2 mm). Valve stroke
< 1.2 mm results in 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 open.
Manual operation
A 3-mm hexagonal wrench can be used to move the actuator to any position.
