Meaning
Major unbalance of the neutral point voltage.
Detection of converter zero-sequence
overcurrent.
Battery current unbalance.
Sudden change of the DC voltage level.
Detection of DC ground fault UF159 exceeds
10 seconds. UPS transfers to bypass.
Power supply voltage to IGBT driver PCB is
below the specified level.
24 hours after input power restoration,
batteries does not reach float voltage level.
Unable to equalize the voltage of various
batteries after 24 hours.
During UVR, status signal from CB2 is ON.
UF157 failure persisted for over 2 hours.
Detection of over temperature at the batteries.
Low level of battery electrolyte solution.
Detection of DC ground fault. Chopper
operation is stopped.
Abnormal behavior of DC current sensor.
UF151 failure is running for over 24 hours.
Failure detection based on battery self-check.
Battery voltage is abnormal.
Detection of a large variation of the difference
between control-only and protection-only
battery voltage.
Poor shared current in parallel chopper circuit;
or improper charging current.
Energy storage device error.
