Electrical connection
All actuators are equipped with a universal supply unit working at a voltage of 24 VAC/DC.
The safety operation of the spring return function works if the supply voltage is cut.
An over-current protection fuse < 10 A has to be provided by installer.
Note: the initial current is appr. 2 A for 1 second.

Self adjustment:
To adjust the signal input /output to the angle of
rotation of the damper/valve the button (T) must
be pushed for a minimum of 3 sec.

Attention
During commissioning apply a self adjustment drive.
Regard duty cycle at motor running times!
Never use spring return actuators without external load.
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 60 seconds (30 sec. “On”, 30 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 operation
The rotation direction (clockwise/counter clockwise) depends on left/right
mounting of the actuator to the damper.
▪ 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
