A) Self adjustment of angle of rotation:
Switch (S) into position 02, then push button (T) for minimum 3 seconds. The actuator
will drive into both end positions to be adjusted. LED indicates GREEN.
Adjustment time needs approx. 93 sec. (90 sec. “On”, 3 sec. “Off”). After that, switch
(S) into the position acc. with your required torque and running time.
B) Selection of running time and torque:
Put switch (S) into the correct selected position in acc. to above table.
The selected parameter will work at next operation of the actuator.
Adjustment can be done even without supply voltage. If supply voltage
is available turn switch only if actuator is not running.
C) Function of the ExPro-TT-... in the Ex-i circuit:
If the sensor opens the Ex-i circuit the actuator runs into its safety end-position with
spring return.
D) Additional information for control mode:
a closed = actuator goes ON
a open = spring return mode
The rotation direction depends on left/right mounting of the actuator to the
damper/valve.

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 or
line 3 opened.
For electrical connection inside hazardous areas a terminal box is required (e.g. RedBox).
An over-current protection fuse < 10 A has to be provided by installer.
Note: The initial current is appr. 2 A for 1 second.
Supply at auxiliary switches must be the
same as supply of actuator and on same
fuse in case of power is switched.
