Non Safety-Related Outputs
The outputs other than the OSSD are "non safety-related outputs" which inform a PLC or similar non-
safety devices of the operations of the GL-RHG.
All non safety-related outputs other than the muting lamp output can be connected to both PNP and NPN
input devices. Refer to the time charts mentioned in this manual because the output logic is different
depending on the connected device. On the other hand, the muting lamp output is an NPN open collector
output.
"4-2 I/O Circuit Diagram" (page 4-3)
 Available non safety-related outputs according to the cable type
The non safety-related outputs on the transmitter are available only when wired synchronization system is
applied.
"1-2 Part Description" (page 1-8)
AUX (Auxiliary) output (Receiver, red wire)
This output informs an external device (non safety-related device) of the operations of the GL-RHG and oper-
ates in synchronization with OSSD operation. It can only be connected to a PLC or similar non-safety
devices.
See
"Functions" (page 2-4) for the information of wiring system and cable type to activate this function.

DANGER
The non safety-related output is not allowed to be used as a safety output for safety-related
control systems. The non safety-related output does not constitute a part of the safety-
related control system. Usage of the non safety-related output as a safety output may result
in significant harm to the machine operators including injury or death.
