Safety functions
Obstruction in opening direction
If the door wing encounters an obstacle during the opening motion, the drive unit is
stopped. The door wing is closed as soon as the hold-open time has expired. Upon
the next opening motion, the door wing moves at the programmed opening speed up
to the position where the obstacle has been detected and, provided that the latter has
been removed in the meantime, from there at slow speed up to the programmed OPEN
position. The following opening motion will then be carried out in the normal fashion.
Obstruction in closing direction
If the door wing encounters an obstacle during the closing motion, the drive unit is
stopped and the door wing reopened up to the OPEN position. During the next closing
motion, the door wing moves at the programmed closing speed up to the position
where the obstacle has been detected and, provided that the latter has been removed
in the meantime, from there at slow speed up to the CLOSED position. The following
closing motion will then be carried out in the normal fashion.
Limitation of the power
The static driving power on the main closing edge is limited to 150 N.
Function in the event of a mains failure
In the event of a mains failure, the door can be manually opened and closed.
