Fault Meaning
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
Low Battery Warning
Before the EOD, battery low pre-warning will occur. After this pre-warning, the battery will
have the capacity for 5min discharging with full load. The time is user-settable from 3min to
60min (5min by default)
Battery Ground Fault Battery has ground fault
BCB Status Abnormal Logic conflict between BCB drive signal and feedback signal
Discharge Current Limit Discharge current is over limit, close the discharger
Discharge Fault
Discharger has fault, bus voltage too high or too low during discharger start or soft start,
exceeding the setting value
Output Overload Timeout
The UPS overload status continues and the overload times out. When the time has expired,
the load automatically transfers to the bypass
Output Fuse Fail At least one of the inverter output fuses is blown
Output Voltage Abnormal At least one phase of the output voltages is abnormal
EPO Dry contact input signal or external EPO command received
Output Disabled EOD event happened. Check the battery voltage
Control Power Fail The auxiliary power failure or power-off
Operation Invalid
Maintenance bypass switch is closed when the parallel system is on inverter, or output switch
and maintenance bypass switch are closed when the inverter is on
Rectifier DSP SW Error Rectifier DSP program incorrect, may burn the inverter or bypass DSP
Inverter DSP SW Error Inverter DSP program incorrect, may burn the rectifier or bypass DSP
Inverter FPGA SW Error Inverter FPGA program incorrect, may burn the bypass FPGA
Power Hardware Mismatch The model information set at the host is inconsistent with the actual situation
Parameter Config. Fail EEPROM operation failed during DSP configuration, or DSP parameter issued by MON failed
Module Overtemperature The power tubes of rectifier and inverter inside the module have overtemperature
Charger Overtemperature The power tube of charger inside the module has overtemperature
Pwr. Mod. Unauthorized
The module does not work due to unauthorized power module. Please contact the service
center of the manufacturer to get corresponding authority
HMI Unauthorized
The UPS does not work due to unauthorized HMI. Please contact the service center of the
manufacturer to get corresponding authority
