19.3 Menu 9.6 - Configuring the blockage detection
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.

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.
If the motor type cannot be precisely determined, then
a suitable setting for motor type and sensitivity must be
determined by trial and error.
