G2020 Series UPS Installation and Operation Manual – 94861-004
Meaning
Detection of inverter output phase
overvoltage.
Detection of zero-sequence
overcurrent.
Discrepancy between output voltage
and inverter voltage, or between
output voltage and bypass voltage.
Output voltage is out of the specified
range.
Contactor 52C failed to open during
load transfer from inverter to
bypass.
Load transfer due to overload for
over 4 times within 5 minutes.
No detection of another UPS voltage
signal.
AD reference has an abnormal
value.
Detection of an external interruption
during the software execution.
Timer does not reset in the specified
period (WDT settings)
Detection of an abnormal clock
speed in the DSP or FPGA.
Control power supply voltage is
below the specified level.
Inverter voltage is out of the
specified range.
Backup control power supplies
exhibit abnormal condition.
Cable disconnection in the parallel
interface board during load supply.
Major communication error during
parallel operation.
Major abnormal detected in the
converter unit
Major abnormal detected in the
inverter unit
Major abnormal detected in the
chopper unit
Major abnormal detected in
Backup control power supplies
exhibit abnormal condition.
Synchronization status signal is
being received for a considerable
time.
Minor communication error during
parallel operation.
Unable to synchronize the inverter
output and the bypass voltage.
Cable disconnection in the parallel
interface board.
Unable to achieve synchronization
for parallel operation.
No control response from another
UPS although its detection is
possible.
Overload detection signal is being
received continuously for a
considerable time.
No answer for sending
synchronizing signal.
Abnormal clock speed of the parallel
control board processor.
