Override

With the override function, a machine can be restarted even though the safety zone is viol-
ated by material.
The aim is to clear the danger zone of any material that may have accumulated due to a
fault in the operating cycle.
If there is a pallet in the safety zone, for example, and the conveyor can no longer be
switched on because the safety laser scanner is keeping the OSSDs switched off (because
the safety zone is not free), the accumulated material cannot be transported away from the
zone.
Activating the override function allows intervention and enables the conveyor to be restar-
ted.
The safety laser scanner has two connections for override, which are connected via N/O
contacts at 24 VDC (Override 1) and 0 VDC (Override 2). Both contacts are closed if the
override function is activated.
The override function can be activated for the first two OSSDs each when muting is activ-
ated for these OSSDs.
