module removed module is removed Cabinet Alarm Information No. Display message Meaning Rectifier detected faulty. Rectifier and inverter and Rectifier Fault charger shut down. The temperature of heat sink is too high to keep the Rectifier Over Temperature rectifier running. Charger and inverter shut down. The temperature of the inverter heat sink is too high to Inverter Over temperature keep inverter running. Rectifier over-current Rectifier failure due to over-current Input thyristor failure Failure of input thyristor Battery discharge thyristor Failure of battery discharge thyristor failure Battery charge thyristor failure Failure of battery charge thyristor At least one of the cooling fans fails. Rectifier and Fan fault inverter and charger shut down. Rectifier, inverter and battery converter are shutdown DC Bus over-voltage due to high DC bus voltage. Rectifier, inverter and battery converter are DC Bus under-voltage shutdown due to low DC bus voltage. If the difference between positive DC bus and negative DC bus unbalance DC bus exceeds 30V, this warning shall occur. Soft start fault Rectifier could not be started due to low DC bus voltage If Input Neutral line is missing or disconnected while Input Neutral line missing the UPS is in operation, the UPS will generate Neutral line failure alarm and go into Battery mode. Battery Reverse The polarity of the battery is reversed. No Battery Battery is disconnected Positive Battery Charger The positive battery Charger is fault. The charger will be shut down. fault Negative battery charger The negative battery charger is fault. The charger will fault be shut down. The battery voltage is too low and the charger has been Battery under-voltage deactivated. The battery voltage is too high and the charger has been Battery over-voltage deactivated. The UPS is in battery operation and the battery voltage Battery under-voltage is low. pre-warning Note: Runtime is limited in duration. Mains frequency is out of limit range and results in Mains freq. abnormal rectifier shutdown. Mains Voltage exceeds the upper or lower limit and Mains volt. Abnormal results in rectifier shutdown.
