I. Temperature rise
While operating the ExMax actuator following parameters have to be aligned:
At overload resp. temperature rise the actuator will remain functionless until cooling.
During cooing the LED is red.
II. 3-pos operation
ExMax (RedMax) actuators are in the best way suitable for the 3-pos operation.To protect
such elements as gears and mounting elements against harmful influences like minimum
pulse time, ExMax (RedMax) actuators are protectet via internal electronics.
The internal electronic permits impulses > 0,1 sec., the puls length must be 0,5 sec.
By shift in direction the interval is 1 sec.
III. Use at low ambient temparature below -20°C
All ExMax (RedMax) actuators are equipped with a regulated integrated heating device
designed for employments down to -40°C ambient temperature.
The heater will be supplied automatically by connecting the constant voltage supply on
the clamps 1 and 2.
Following parameters are to be considered by ambient temperaure < 10°C:
1. After mounting the actuator must bei immediately electrically connected.
2. The actuator will only be activated after the operating temperature has reached at least -20°C
3. The adjustment options are only ensured after this heating up period.
IV. Mechanical protection
1. The actuator must be operated with an outside load of at least 10 Nm.
2. After installing the actuator to the damper/armature an automatic alignment has to be
accomplished, in order to obtain a gentle blockade/stop. This function protects the
damper/armature by reducing the end positions/blockade speed in order to avoid
mechanical overload. The actuator alignes specifically once with 90 sec/90° onto each
position, recognizes the blockade position in order to reduce the motor performance
during operation briefly before reaching the end/blockade position.
