Safety functions
Obstruction in opening direction
If the door leaf meets an obstacle during the opening motion, the drive unit is stopped.
The leaf is closed upon expiration of the hold-open time. The next opening motion is
carried out with the programmed opening speed; the leaf moves up to the position
of the obstacle and from there - provided that the latter has been removed in the
meantime - with reduced speed up to the programmed OPEN position. The following
opening movement is then performed in the normal manner.
Obstruction in closing direction
If the door leaf encounters an obstacle during the closing motion, the drive unit is
stopped and the door leaf opens up to the OPEN position. During the following clo-
sing motion, the door leaf moves at the programmed closing speed up to the position
of the obstacle and from there - provided that the obstacle has been removed in the
meantime - with slow speed up to the CLOSED position. The next closing movement
is then performed in the normal manner.
Limitation of the force
The static drive power on the main closing edge is limited to 150 N.
