I. Operation with 3 sec. motor running time mode
While operating the ExMax actuator in 3 sec. mode following parameters have to be aligned:
1. Maximum cyclic duration 10% ED, maximum 1 cycle/min.
2. Exeeding above mentioned parameter the actuator will remain functionless until cooling
has occured. At 2 wire mode (circuit diagram SB 2.1 / 7.0 / 7.2) the cool down is
funtionless. The cool down must be guaranteed by control system.
3. The actuator must be operated with an outside load of at least 3 Nm.
4. 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 30 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.
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 20 impulses with < 0.5 > sec. cyclic duration, afterwards at least
1 impulse > 1 sec. must follow. If clocked with more than 20 impulses each < 1 sec. the
actuator will adjust into a suspend mode.There after a reset is mandadory and will be
achieved by briefly switching of the supply voltage for about 2 sec..The controll unit has
to be parameterized in order to be set within the above mentioned duration limits.
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.
