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 inside hazardous areas an Ex-e terminal box, certificated in acc.
with ATEX is required (e.g. ExBox).
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

the switches were operated with higher voltage or current.

A) Self adjustment of angle of rotation
Turn switch (S) to position 02. 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) Function of the ExPro-TT-... in the Ex-i tripping circuit
When the ...Pro-TT’s tripping circuit is opened the actuator runs into its end position
with spring return.
D) 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.
Attention
During commissioning apply a self adjustment drive.
Regard duty cycle at motor running times!
Never use spring return actuators without external load.
