Muting sensors parameter: 4P
Parallel muting with 4 sensors enables a second group of
muting sensors to detect the end of the movement of the
transported good.

The sensors of group B must be arranged so that they
remain triggered as long as the sensors of group A at the
entry are still triggered. As soon as the sensor group A and
the light curtain no longer detect an interruption in the
protected area, the sensor group B reactivates the protec-
tive function of the light curtain (with motion direction A
to B) after the muting area is vacated.
As soon as the sensor group A and the light curtain no longer
detect an interruption in the protected area, the sensor
group B reactivates the protective function of the light
curtain (with motion direction A to B) after the muting area
is vacated.
Both directions of motion are permissible and there any
signal sequence is possible:
• Group A -> Group B
• Group B -> Group A
Sensor group A is connected to function block coils LM..A1
and LM..A2. Sensor group B is connected to function block
coils LM..B1 and LM..B2.
