CAUTION!
If the safety light grid is in a muting status, the OSSDs continue to be
switched on
The connected machine remains in operation and so represents a potential
hazard.
– Prevent access to the danger zone during muting.
Identification of the conveyed material (pallets, vehicles...) must be guaranteed with all

Technical implementation
The safety light grid
has two inputs, Muting 1 and Muting 2, to activate the muting function.
The muting sensors are connected to these inputs. The muting sensors must be positioned
and installed at a right angle to the receiver and transmitter (see
Installation and
wiring [

).
}
The muting status occurs
– when the first sensor and the second sensor detect a conveyed material simultan-
eously or
– when the first sensor has detected a conveyed material and the second sensor also
detects it max. 4 s afterwards.
