Automatic reversing in the event of meeting an
obstacle.
In the event of blockage, the motor runs in the opposite direction
for approx. 2 seconds to relieve the roller shutters.
More information about blockage detection:
◆
if excessively long 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 detection must be deactivated for this
type of motor.
NOTE:
◆
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.
