Alarm Meaning
LBS Abnormal LBS is abnormal
Input Transf. Overtemp. Input transformer overtemperature
Output Transf. Overtemp. Output transformer overtemperature
Load on Maintainace Bypass UPS in maintainance bypass mode
Battery Voltage Low
Battery voltage too low and out of the normal range based on the battery cells number
setting
Byp. SCR Fan Abnormal The internal fan of bypass module is faulty
Top-outlet Fan Abnor. The fan of top air outlet is faulty
Bypass Temperature The bypass radiator has overtemperature
Table 4-6 UPS Fault Message List
Fault Meaning
Input Backfeed Battery voltage fed back to rectifier input. Check that the rectifier SCR is normal
Input Current Abnormal
Battery load sharing imbalance or mains battery frequent transfer more than 5 times
within 5 min
Input Current Limit Input current over limit
Input Neutral Missing AC rectifier input neutral line not detected
Rectifier Fault Bus voltage abnormal or battery SCR short circuit
Rectifier Soft Start Fail Owing to low DC bus voltage, the rectifier will report this alarm
Inverter Fault
Inverter output voltage outside specifications. Load transfers to bypass if bypass is
available
DC Bus Abnormal Shutdown DC bus voltage outside specifications. Load transfers to bypass if bypass is available
DC Bus Overvoltage
DC bus overvoltage makes rectifier, inverter and battery converter shut down. Load
transfers to bypass if bypass is available
Load Impact Transfer
A transfer to bypass occurred due to a large step load. The UPS can recover
automatically. Turn on the load equipment in stages to reduce the load impact on the
inverter
Other Module Transfer
All UPSs in the parallel system transfer to bypass at the same time when one of them
needs to transfer to bypass. This message appears on the LCD of the UPS with passive
transfer to bypass
Bypass Abnormal Shutdown Both the bypass and inverter voltages are abnormal, and the output is off
Inverter Relay Fail
At least one of the inverter relays is opened or shorted. This fault is locked until mains
power-off
Bypass STS Fail
At least one of the STSs at the bypass side is open or shorted. This fault is locked until
power-off
Other Bypass STS Fail The adjacent bypass STS open circuit fault or short-circuit fault
Bypass Backfeed The bypass back-feed is faulty
Charger Fault Battery charger has a failure
