NOTICE
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).
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 posi-
tion and the valves are closed.
Manual operation
A 3-mm hexagonal socket wrench can be used to move the actuator to any position.
To move the actuator stem manually
1. Open the cover using a proper screwdriver. Note that IP54 protection does not apply if
the cover is open.
2. Press and hold down button (a) illustrated below for at least three seconds.
 The actuator ignores any control signal from the controller.
3. Adjust the position of the actuator stem by rotating hexagon socket (b) illustrated below
clockwise or anti-clockwise.
 The actuator stem moves down if you rotate clockwise; it moves up if you rotate anti-
clockwise. The manually set position is retained.
4. Press and hold down button (a) illustrated below again for at least three seconds.
 The actuator runs a self-calibration automatically. Control signal sent from the con-
troller takes effect.
5. Close the cover to ensure IP54 protection.
