Muting 2-Sensor L-Type Unidirectional
The CR30 safety relay has a function block that supports 2-sensor L-type
muting. With this function block, the material can only move in one direction:
from the hazard area to the non-hazard area. The two muting sensors are located
within the hazard area, and the material must be large enough to block both
sensors and the light curtain. The function block contains timing parameters that
allow you to accommodate a wide range of operating speeds.

The material can only flow from the hazard area to the non-hazard area. The
material must be large enough to block muting sensor 1, muting sensor 2, and the
light curtain concurrently.
