Time monitoring for the muting function can be selected via DIP switches 1 and 5 (see
Set-
ting the functions [
42]
).
CAUTION!
If time monitoring for the muting function is set to ∞, the muting function is
not cancelled until the muting sensors are no longer active.
This setting does not comply with the specifications of EN ISO 61496-1.
Avoid a situation in which sustained muting is not detected.

Override
With the override function, a machine can be restarted even though material is interrupting
one or more beams.
The reason for this is to clear the danger zone of any material that may have accumulated
due to an error in the operating cycle.
For example, if there is a pallet in the protected field and the conveyor can no longer be
switched on because the safety light grid
is keeping the OSSD switched off (because
beams are interrupted), 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 light grid has two connections for override, which are connected via N/O con-
tacts at 24 VDC (Override 1) and 0 VDC (Override 2). Both contacts are closed if the over-
ride function is activated.
