Buzzer Fault Name Definition
PCB Board Component/Circuit
#1,#4
Keep
Beeping
Bus abnormal
The DC BUS voltage higher or
lower than the predetermined
level. Last for a certain of time.
The PSDR board or control board
Mainly check that the IGBT and SCR etc power components for
the PFC and the utility power SCR are well. Meanwhile check
that the components on the drive circuit are well.
#1,#5
Keep
Beeping
INV Fault
When inverter works, Inverter
output voltage become abnormal,
higher or lower than
predetermined level for a certain
of time.
The PSDR board or control board
The power components for power INV and on the drive circuit are
normal. Check that the IGBT protective circuit and some PFC
components are normal.
#1,#2
Keep
Beeping
Overload
The UPS is overload, and the
overload time exceeds the
endurance time.
Remove unimportant loads to be less than 90%.
Restart the UPS to enter into the INV mode if it is fault at the moment.
Over temperature can cause by external environment, over load, or bad ventilation,
Make sure the ambient temperature should within the operation ranged and the ventilation should not
be blocked. Otherwise the there may be some hardware failure
#1,#6
Keep
Beeping Over
temperature
Temperature of the internal
critical components increases up
to protective threshold.
PSDR
1. Over temperature may caused by failure of snubber circuit of
INV/PFC.
2. Or probably cause by a incorrect detection, it maybe
misplayed by the control board or the NTC on the CN107 of
the PSDR board is damaged.
3. Fans driver failure cause also can over temperature
#1,#2,
#5 Keep
Beeping INV output short
circuit
When the UPS inverter output
very high current and output
voltage keep less than 50V.
Checks the load, clean short-circuit on the output of the UPS.
#1,#3
#4 Keep
Beeping Communication
abnormal The CPU cannot establish
communication.
The control board or the communication cable damaged.
#1
Keep
Beeping
Battery Open
The UPS transfer to battery
mode but the battery bank is not
properly connected or battery is
very weak can’t support the UPS
continue work on battery mode
Check the battery or battery connection, replace the damaged battery, replace failure battery
connector/breaker, otherwise, battery-detecting circuit may damage.
