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 terminal box, certificated in acc. with
ATEX is required (e.g. RedBox).

Special makes RedMax-..-VA/-CT
Self adjustment:
To adjust the signal input/output to the Angle
of rotation of the damper/valve the button T
must be pushed for minimum 3 sec.
Function of switch a and b:
- a closed, On (Off) - in acc. to left/right mounting ot the actuator
- b closed, Off (On) - in acc. to left/right mounting ot the actuator

If 40 sec. or 60 sec. mode is selected for
motor and/or spring return, the self adjus
tment of angle of rotation must be started.
Never use actuators in this mode without
external torque/force.

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) Change from modulating into 3-pos operation mode:
Push button (T) 3 times. LED changes from green to yellow.
Push button within next limits:
- Push time min. 0,2 sec.
- The max. time for 3 push is 5 sec.
D) Change from modulating into 3-pos operation mode:
Push button (T) 3 times. LED changes from yellow to green.
E) 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.
F) Reverse function:
Bridge between wiring 3 and 4 (signal wise) gets a reverse function of Y and U.
