Muting Lamp
The muting lamp warns an operator in the event that the light curtain is muted. Depending on the risk analysis, often a muting lamp,
monitored by the MSR42 control unit (controller box), signals the muting procedure. The size and the brightness of the connected lamp
must also be designed as required by the safety analysis.
By default the muting lamp is not monitored in the muting controller box. However, the muting lamp must be used (reference the MSR42
user manual for further information). To change the muting lamp to monitored, reference the “Configuration and Diagnostic Tool” user
manual.
If an error in the muting sequence has occurred, the muting lamp will blink (ca. 1 Hz), indicating that the muting condition has not been
initiated, or has been discontinued.
The plug “muting lamp” offers to connect an additional muting lamp to the controller box.

Operating
The control of the muting is done with one spring return switch called Reset/Override. It triggers the start input of the MSR42 controller.
The control signal on the Quick-QD M12 connector “PWR I/O” – Pin 8 (Start) works in parallel to the key switch.
