Diagnostic LEDs and Troubleshooting
The GLT has five LED indicators to provide operating status and diagnostic
information.
LEDs During Power-Up
During power-up, the LEDs turn ON and OFF during their self-check process.
The self-check takes about 3 seconds.

LEDs During Diagnostics
Diagnostics are indicated by the flashing of the LED indicators. The PWR/Fault
indicator shows the major fault. The IN1 indicator shows more detail.
The flashing rate pauses and then repeats itself.
