| Alarm message |
| Description |
| Rectifier comm. fail | Internal RS485 communication failure between monitor and rectifier | |
| Mains volt. abnormal |
| Mains Voltage exceeds the upper or lower limit and results in rectifier shutdown. Check the input |
|
| ||
|
|
| |
| Mains undervoltage | Mains voltage is undervoltage. Check the input line voltage | |
| Mains freq. abnormal |
| Mains frequency is out of limit range and results in rectifier shutdown. Check the input voltage and |
|
| frequency | |
|
|
| |
|
|
|
|
| Battery fuse fail |
| Battery fuse flowout led to BCB tripping |
| Rectifier block | Rectifier detected faulty. Rectifier shuts down. Battery discharges | |
| Rectifier overtemp. |
| The temperature of heat sink is too high to keep the rectifier running. The UPS can recover |
|
| automatically. Check the environment and ventilation | |
|
|
| |
|
|
|
|
| Input fuse fail |
| Input fuse blowout led to rectifier turning off |
| Control power 1 fail | UPS operates but Control Power is not available | |
| Control power 2 fail | UPS operates but Redundant Control Power is not available | |
| Mains phase reversed | Rectifier AC input phase sequence is reversed | |
| Rectifier current limit | Rectifier overcurrent led to power limiting operating | |
| Soft start fail |
| Rectifier could not start due to low DC bus voltage |
| Input filter fault |
| Filter inductor overtemperature led to filter contactor tripping |
| Filter contactor fault | Filter contactor operation abnormal | |
| Filter overcurrent |
| Mains power outside the normal voltage or frequency range of the input passive filter results in filter |
|
| overcurrent. Please find out the reason for the mains power abnormality | |
|
|
| |
|
|
| |
| REC drive cirtuit fault | Rectifier being off due to improper connection of rectifier drive cable or rectifier type setting error | |
| REC input Ph. missing | Rectifier input phase missing. Check the input power connection or if the mains power is abnormal | |
| DC bus over voltage |
| Rectifier and inverter were shut down because DC bus voltage is too high. Check whether there is a |
|
| fault in rectifier side | |
|
|
| |
|
|
|
|
| Bus capacitor overvolt |
| Bus capacitor voltage exceeds 350V, rectifier is off. Check the voltages of the two groups of bus |
|
| capacitors | |
|
|
| |
|

|
| and of the Battery supply | |
|
|
| |
|
|
| |
| PPF online | Reactive input filter connected | |
