Muting Function Block Parameters
Parameter Settings/Range Default
Muting Mode • Parallel muting with 2 sensors
This pattern is suitable for applications at a conveyor entrance. Use this pattern when
two retro-reflective photoelectric sensors are set up as muting sensors with intersecting
detection zones.
• Sequential muting (forward direction)
This pattern is suitable for applications at a conveyor entrance. Use this pattern when
four through-beam photoelectric sensors are set up as muting sensors.
• Sequential muting (both directions)
This pattern is suitable for applications at a conveyor entrance or exit. Use this pattern
when four through-beam photoelectric sensors are set up as muting sensors.
• Position detection
This pattern is suitable for applications in which muting is controlled by a switch input.
Use this pattern to temporarily disable the light-interruption signal of the light curtain
when an operator is placing an object in the machine opening, and the machine is in a
state where it will not harm the operator (hazards are in a different zone of the machine).
In all of these setting explanations, the muting sensors are on when detection is performed
and off when detection is not performed.
