L-Muting
With L-muting, the light curtain is muted if the input signals switch to 24 V DC in accordance
with a certain sequence: MUTING1 must be activated first; only then can MUTING2 be
activated.
If MUTING2 should activate before MUTING1, the device will not switch to muting mode;
"T12" represents the activation delay between MUTING1 and MUTING2.
The muting function ends once the time has elapsed, which corresponds to a multiple of the
activation delay between the two sensors (this time corresponds to m * T12). The value "m"
(multiplier T12) must be selected by the user. The value is preset with m = 2.

The sensor labelled A is positioned furthest away from the light curtain, which is why its
beam is recorded first. With reference to the diagram below and in consideration of the fact
that the package only passes from right to left, sensor B cannot be recorded first. If this
should happen, the light curtain is not muted.
