Sensitive obstacle detection
Setting the special function fabric untensioning
If an obstruction is detected during
the drive (e.g. wind load during the
closing movement), the drive stops,
reverses and tries to move past the
obstruction a second time. If this
fails, the drive switches off after the
third attempt .
If obstructions occur at different
points, the drive restarts three times
in each case. After a maximum of
ten stops caused by obstructions at
different points, the drive reverses
and switches off.
Approx. 15 cm from the lower limit
position, the drive interrupts oper-
ation immediately following the first
detection of an obstacle and makes
no further attempt to continue.

fabric untensioning function
On delivery, the fabric untensioning
function is deactivated on drive types

gramming button until the drive
clicks once. Press the programming
button again and also the stop and
RETRACT button until the drive
