Input reverse
polarity
protection
When DC input reverses polarity, the
LCD would be off.
The equipment would not be damaged. Resume work normally after correction.
Input over
voltage
protection
Inverter mode:
DC input voltage exceeds the max.
input voltage
Fault code "IOV"
Buzzer sounds in short cycle
The Inverter stops working and switches
to the bypass mode. AC output continues
(If no bypass input is available, or the
bypass circuit breaker is open, AC output
will stop.)
When the input voltage backs to normal,
fault warning stops, auto switch to
inverter mode.
Bypass mode:
DC input voltage exceeds the max.
input voltage
Fault code "IOV"
Buzzer sounds in a long cycle
Bypass works normally, AC output
continues. When the input voltage backs to normal,
the fault warning stops.
Input low voltage
protection
Inverter mode:
DC input voltage is lower than the min.
input voltage
Fault code "ILV"
Buzzer sounds in short cycle
The Inverter stops working and switches
to the bypass mode. AC output continues
(If no bypass input is available, or the
bypass circuit breaker is open, AC output
will stop.)
When the input voltage backs to normal,
fault warning stops, auto switch to
inverter mode.
Bypass mode:
DC input voltage is lower than the min.
input voltage
Fault code "ILV"
Buzzer sounds in a long cycle
Bypass works normally, AC output
continues. When the input voltage backs to normal,
the fault warning stops.
Output voltage
abnormal
AC output voltage exceeds the range of
220±20Vac
Fault code "OVA"
AC output stops.
AC output voltage recovers to the range
of 220±20Vac.
