    "Output" goes out. A low signal is present at semiconductor output Y36. Muting lamps The muting controller PMUT X1P is designed for use with one or two muting lamps. As soon as the inputs of the light guard are muted, the Muting lamp ML1 will light. The PMUT X1P monitors the connected muting lamps during the muting cycle.
