Buzzer sounds in short cycle
Output overload
The output power is 1.1 times greater
than the rated power
Fault code "OOL"
Buzzer sounds in short cycle
AC output stops Reduce the load power.
Output short
circuit
Fault code "OSC"
Buzzer sounds in short cycle
Shut off the output immediately, auto
recover the output three times (The first
time delay for 5 seconds, the second time
delay for 10 seconds; the third time delay
for 15 seconds).
Recover the output after the load short
circuit failure is cleared
The equipment would auto-recover the
output every 24 hours after the fault
happened. If the fault is cleared, the
load output will recover only after
manually restart.
IGBT over
current
Fault code "ISC"
Buzzer sounds in short cycle
Shut off the output immediately, auto
recover the output three times (The first
time delay for 5 seconds, the second time
delay for 10 seconds; the third time delay
for 15 seconds). Suppose the IGBT over current state
continues after three times auto-
recovery. In that case, the output will
recover only when the fault is cleared
and manually restart.
Radiator over-
temperature
protection
The radiator temperature exceeds 85
℃
Fault code "ROT"
AC output stops
When the temperature backs to normal,
the fault warning stop, AC output
recovers.
Internal over-
temperature
protection
Internal temperature exceeds 60
℃
Fault code "IOT"
AC output stops
When the temperature backs to normal,
the fault warning stop, AC output
recovers.
Bypass
overvoltage
Inverter mode:
Bypass input voltage exceeds 264VAC
Fault code "BOV"
Buzzer sounds in a long cycle
The inverter works normally, AC output
continues. When the bypass input voltage backs to
normal, the fault warning stops.
Bypass mode:
Bypass input voltage exceeds 264VAC
Fault code "BOV"
Buzzer sounds in short cycle
Auto switch to inverter mode, AC output
continues (if the inverter circuit has fault
too, AC output will stop). When the bypass input voltage backs to
normal, fault warning stops, auto switch
to bypass mode.
