Partial muting

The muting type can be configured: total or partial muting. Partial muting can prove useful
when the user wishes to limit the effects of the muting function exclusively to the selected
zones. Each of the zone A-D includes a quarter of the light curtain's length. With a light
curtain with a length of 40 cm, this is 15 cm.

7.8 Override

The override function allows the user to disable the safety functions if the machine needs to
be restarted, even though one or more of the light curtain beams have detected an object in
the protected field. For example, a typical application would be to examine recurring
blockages more precisely and to rectify the cause. These may be work materials between
the light curtain's transmitter and receiver, which trigger the light curtain.
The override's redundant inputs must be connected to a 24 V DC N/O contact and an
earthed N/O contact.
In accordance with the guidelines, the light curtain is equipped with two override activation
inputs: OVERRIDE1 and OVERRIDE2 (respectively, Pin 4 of the 12-pin M12 connector and
Pin 9 of the 12-pin M12 connector – of the receiver).
