CAUTION
Never intervene manually during self-calibration.
NOTICE
●
Correct calibration is only possible with valve stroke > 0.05 inch (1.2 mm). Valve stroke
< 0.05 inch (1.2 mm) > 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.
To move the actuator stem manually
1. Open the cover using a proper screwdriver.
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 hexagonal wrench (b) illustrated
below clockwise or counter-clockwise.
– The actuator stem moves down if you rotate clockwise; it moves up if you rotate
counter-clockwise. The manually set position is retained.
4. To exit manual operation mode, 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
controller takes effect.
5. Close the cover.
NOTICE
If operating voltage is applied to actuator, press button (a) before and after manually
adjusting the position of the actuator stem.
If no operating voltage and control signal are
applied, manual operation can be done without pressing button (a).
Cabling operation
1. Unscrew cover screw
