RedMax actuators are equipped with a universal supply unit working at a voltage range
from 24 to 230 VAC/DC. The supply unit is self adjustable 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 t erminal box, certificated in acc. with
ATEX is required (e.g. RedBox).

EEx-i intrinsic safe data
If 3 sec. mode is selected, the self adju
stment of Angle of rotation must be started
and operation mode of max. 10% ED
must be guaranteed.
Never use actuators in this mode without
external torque/force.
Attention!

Standard wiring = spring return in ~10 sec.

A) Self adjustment of Angle of rotation:
Switch (S) into position 02 (low torque) or 07 (high torque), then push button (T) for
minimum 3 seconds. The actuator will drive into both end positions to be adjusted.
LED indicates green.
Adjusmtent time needs approx. 60 sec. (30 sec. On, 30 sec. Off). After that, switch S
into position 00-09 in 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) Running time spring return:
The running time of 3 or 10 sec. spring return is selected by wiring
(see wiring diagrams SB 7.0/7.1).
D) Additional information for 3-pos operation:
a closed, b open = direction I
b closed, a open = direction II
a and b closed = Motor doesn't work
a and b opened = Motor doesn't work
Direction (I and II) depends on left/right mounting of the actuator to the damper/valve.
You can change direction of the motor by changing electrical wiring terminal 3 and 4.
E) Function of a passive sensor in the EEx-i circuit:
If the sensor opens the EEx-i circuit the actuator runs into its safety end-position with
spring return
