I. Operation with 3 sec. motor running time mode
Note following at 3 sec. motor running time:
1. The 3 sec. motor running time mode is only in switch position 0 and 5 and at a constant
supply voltage on terminals 1 and 2 which must be in minimum for 1 minute applied
available.
2. The actuator opens at voltage on terminal 3 (resp. closes), and closes at voltage on
terminal 4 (resp. opens ) depending on mounting position of the actuator.
3. The max. duty ratio is 10 % resp. 1 cycle / minute. Between two fully cycles to the same
direction there must be a minimum intermission of 1 minute. The actuator is blocked if
the break time is less than 1 minute. The release for the next cycle is made automatically
by an internal timing relay.
4. Same function is applied on spring return actuators. Faile safe operation is regarded
same as a motor running cycle.
5. If its tried to use the 1 wire On/Off methode in switch position 0 and 5, software changes
the running time temporarily and automatically to 15 sec. motor running time to protect
the actuator for overheating due to uncontrolled duty ratio.
6. The actuator must be operated with an outside load of at least 3 Nm.
7. 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.
