All actuators are equipped with a universal supply unit working at a voltage range from
24...240 VAC/DC. The supply unit is self adjusting to the connected voltage!
The safety operation of the spring return function works if the supply voltage is cut.
For electrical connection a terminal box is required (e.g. InBox).
An over-current protection fuse < 10 A has to be provided by installer.
Note: the initial current is appr. 2 A for 1 second.
Integrated auxiliary switches signal the rotation angle’s position. U

and I
min
change once
the switches were operated with higher voltage or current.

min. max.
A) Self adjustment of angle of rotation
Turn switch (S) to position 02 (low torque) or 07 (high torque). Press button (T) for
a minimum of 3 seconds. The actuator drives to both end positions and detects the
blocking positions. The LED flashes GREEN during adjustment.
The adjustment takes about 180 seconds (90 sec. “On”, 90 sec. “Off”).
B) Selecting motor running time and torque
Adjust parameters only if actuator is in idle state or without applied potential.
Turn switch (S) to the position required for the intended operation acc. to table
above. The selected parameters will be carried out at the actuator’s next operation.
C) Additional information for control in 3-pos. operation
a closed, b open = direction I
a and b closed
= motor doesn’t work
b closed, a open = direction II
a and b open
= motor doesn’t work
The rotation direction (I and II) depends on left/right mounting of the actuator to the
damper. To reverse the rotation direction (by motor) exchange the electrical wiring
of terminal 3 and 4.
▪ Do not open the cover when circuits are live
▪ Connect potential earth
▪ Close all openings to ensure enclosure protection
▪ Clean only with damp cloth, avoid dust accumulation
