Devices used for muting function
Muting device
• The muting device output must be N.O. (normally open).
• A PNP output muting device is required when using the PNP output type cable and an NPN output mut-
ing device is required when using the NPN output type cable. The muting device must be capable of 2 to
3 mA current.
• Do not use one muting device with multiple outputs in place of two or more muting devices. (Only one
output per one muting device must be used.)
• If the muting device has a timer function that can adjust the output timing, do not use that function.
Muting lamp
When using the muting lamp, it must meet the following conditions.
For an incandescent lamp : rated 24 V DC, 1 to 5.5 W
For an LED indicator : rated current consumption must be 10 to 230 mA.
Detailed operation
Conditions for initiation of muting
Muted condition is initiated if all of the following conditions are met:
• Muting input 2 turns ON within 0.04 to 3 seconds after muting input 1 turns ON
• GL-RHG detects no interruption in the protective zone
• OSSD is in the ON state and remains for 0.5 seconds or more.
Conditions for termination of muting
Muted condition is terminated if one of the following conditions is met.
• Either of the muting inputs goes to the OFF state for at least 5 ms.
• Light curtain goes to an error condition
• Wait input goes to ON state
• The power supply is interrupted or restored.
• Maximum muting period of approx. 5 minutes has been passed.
Reference
When the GL-RHG is interrupted, the GL-RHG cannot go to the muted condition. In this case, you
can apply override function to suspend the safety functions temporarily. "Override function" (page
