KEYENCE GL-RHG Series - Manual (Page 7)

7 E GL-RHG-IM
 During normal operation
*1 When not in the muted condition because conditions for initiation of muting are not met.
*2 When not in the override condition because conditions for initiation of override are not met.
 Error condition
When an error occurs, the OSSD goes to the OFF-state and the GL-RHG goes to the error condition.
For the 7-segment display in the error condition, refer to
"Troubleshooting" (page 8).

NOTICE
If the length for a single GL-RHG unit is 1280 mm or greater, use the following antivibration
mounting bracket additionally as an intermediate support bracket. The antivibration
mounting bracket must be selected according to the mounting bracket and installed on the
center of the GL-RHG unit indicated as position "G".
