Light Curtain Muting Module

Muting is defined as bypassing the protective function on safety related control system such as a safety light curtain during a pre.

Light curtain muting module.

Muting lets materials travel through the light curtain without stopping the hazardous motion. Muting can only occur in a safety condition. Muting light curtain monitoring relays allow the automatic temporary suspension of the safety function if certain conditions are met. Two types of applications are envisaged.

Muting is initiated by signals from muting sensors. The rm 3 mute module is an accessory device used to provide a safety rated muting function in conjunction with omron sti safety light curtains and single beam safety devices. Muting is defined as bypassing the protective function on safety related control system such as a safety. The output switch is normally used for connecting an indicator lamp or as feedback to a plc to confirm safety light curtain inputs at terminals b1 and b2 are overridden e g.

1 enabling personnel access inside dangerous area during the non dangerous part of machine cycle. 2 no 6 amp. When suitable signals have been applied to terminals b2 and b3. Faults at the light curtain muting sensors wiring terminals or safety controller are detected before the next safety demand.

The auxiliary switching circuit energizes when the light curtain is muted e g. 1 nc 25 amp. Muting of the light curtain is done to allow automatically fed material to enter the area. To distinguish between material and persons the system monitors for a certain sequence of events within specific time limitations.

Mutingis defined as bypassing the protective function on safety related control system such as a safety light curtain during a pre determined operation of a machine. Muting is the temporary automatic suspension of the protective function of a safeguarding device like a light curtain. Muting can for example be used to transport workpieces into the hazardous area monitored by a light curtain without stopping the machine. The muting function is the provisional and automatic cut out of the light curtain protective function in relation to the machine cycle.

Muting is the intentional suppression of the protective function of light curtains. Document scopethe xpslcm1150 mute module is an accessory device used to provide a safety rated muting function in conjunction with safety light curtains. The xpslcmut1160 muting safety module is an acce ssory device used to provide a safety rated muting function in conjunction with safety light curtain. In material handling applications material is allowed to pass through the protective field without shutting down the machine.
