3.3 Information on safety cut-off and jam protection
General information on safety cut-off
As soon as the slide path of a sliding sash becomes blocked (e.g. due to an obstacle or because it is stuck), it stops, moves for
approx. 4 seconds in the opposite direction and then comes to a final stop (see figure below).
For increased safety in the area around the bottom shear points between the sliding sash and the sliding sash frame, in
normal motor-powered operation, the sliding sash only moves as far as a defined opening position.

Safety shutdown in systems with light curtain
If additional safety requirements apply, the optional terminal board must be ordered. Also available prepared to be
equipped with a light curtain. To prevent injuries and damage, the safety cut-off function is performed, which brings the
sliding sash to an immediate standstill. If equipped with a light curtain, the sliding sash is opened to its full extent.
