General Description The Muting function block provides both muting and override functions.
Muting When detection is muted, safety functions are temporarily disabled so that
workpieces, pallets, or other objects can be passed through the detection
zone of the Safety Light Curtain. With the Muting function block, the input sig-
nal to the Safety Light Curtain will be temporarily disabled when the muting
start conditions are satisfied, and Output Enable will remain ON until the mut-
ing end conditions are satisfied even if the Safety Light Curtain is interrupted.
