Troubleshooting procedure
NoteAction
Wait at least 1 min after power-on.Make sure the power has been off
for more than 10 seconds.
1
Power on the controller.
• If LED TRK is green, proceed with 3.
• If LED TRK is not green, proceed with
6.
Check LED TRK on Power distribu-
tion board, DSQC1085.
2
• LED PC and LED HMI are green, pro-
ceed with 4.
• LED PC and LED HMI are not green,
proceed with 13.
Check LEDs PC (Power distribution
board, DSQC1085) and HMI (Safety
board, DSQC1087).
3
If the STAT LED is:
• Green, steady: Application is ready and
unit is operational. Proceed with step 5.
• Green (uneven flashing ~1Hz): Installa-
tion Utility Application loaded and ready
for recovery operation. Proceed with
step 5.
• Off or red flashing: The unit is faulty and
needs to be replaced. Proceed with step
13.
Check the STAT LED on the pro-
cessor board (DQSC1086).
4
If the PWR LED is:
• Green, steady: Unit is operational. Pro-
ceed with step 9.
• Green (pulsing ~1Hz): Communication
error to PS-side application. Proceed
with step 12.
• Off or red: Proceed with step 13.
Check LED PWR on Processor
board, DSQC1086.
