Automatic reversing function in the event of a blockage
In the event of a blockage, the motor immediately runs in the opposite
direction for approx. 2 seconds to release the roller shutter.
More information about the blockage detection:
◆
If longer connecting leads are used (>5 m), it is possible that the
blockage detection system will fail to work correctly due to external
interference.
◆
It is possible that the motor will be switched off by the blockage
detection system when moving out of the end points when using
mechanical motors with high switching hysteresis. Blockage detec-
tion must be deactivated for this type of motor.
i
Some motors can trigger undesired reversing when
reaching the end positions (e.g. atypical internal motor
wiring, long cables etc.). In such cases it is recommended
to deactivate the reversing function.
i
If the motor type cannot be precisely determined, then
a suitable setting for motor type and sensitivity must be
determined by trial and error.
