SRTG10KXLI – All 5 fans not running, Event Code 120

[Rocka2002]

Hello Schneider Electric Community,

I need assistance troubleshooting an APC Smart-UPS SRTG10KXLI 10 kVA.

The UPS is displaying “Fan Inoperative” – Event Code 120.

The UPS has five internal fans, and all five fans are not running.

I tested each of the five fans individually using an external 12 V DC power supply, and all five fans operate normally when externally powered.

I also measured the voltage at the fan connectors from the UPS and measured 0 V DC.

Could someone please assist me with the recommended troubleshooting procedure for Event Code 120 on the SRTG10KXLI?

If the system is not under warranty then you may consider the following action items and report back the results:

Logs: Provide the diagnostic logs from the NMC and upload the same to the APC Forum for review.

Wizard: Manually initiate a first start using the setup wizard via LCD Menu.

Default: Manually initiate a default reset via the LCD Menu.

Brain Dead: Complete a brain dead reset three times following this APC FAQ:
