NOTICE
Commission the actuator only with a valve mounted correctly in place!
Self-calibration
The actuator self-calibrates (fully retracted ➙ fully extended ➙ setpoint) after initial connec-
tion of bus voltage, after every download of the application, and after bus voltage recovery.
During calibration, the valve is measured and the positions for “valve open” and “valve
closed” are stored. In KNX S-Mode, it is possible to only calculate the “valve open” position
by working back from a set path from the closed position (to close the valve, the actuator
stem extends until the set force is exerted on the valve).
After every download of the application, calibration takes place and the values determined
are compared. If the values do not match, calibration is repeated twice until two consecutive
value pairs match. These values are then stored and the positions used afterwards.
Recalibration occurs at regular intervals (180 days) and after reset.
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 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 posi-
tion.
Manual operation
Use a 3-mm hexagonal socket wrench to move the actuator to a different 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 the enable/disable button of manual operation for at least three
seconds.
 The actuator ignores any control signal from the controller.
