3.6 Functioning of the integrated safety unit
If the garage door encounters an obstruction during closing, the operator stops
and releases the obstruction by opening the door to the upper limit position, see
chapter Force learning cycle.
If the garage door encounters an obstruction during opening, the drive stops and
moves back to release the obstruction. The door can be closed again by pulsing.
