Please check if rectifier’s fuses, diode, IGBT or PFC diodes
are broken.

Please check if input voltage is abnormal.

70

DC Bus Over
Volt

Voltage of DC bus capacitors is over limitation. UPS
shutdown rectifier and inverter.

71

REC Soft Start
Fail

While soft start procedures are finished, DC bus voltage is
lower than the limitation of calculation according utility
voltage. Please check

1.

Whether rectifier diodes are broken

2.

Whether PFC IGBTs are broken

3.

Whether PFC diodes are broken

4.

Whether drivers of SCR or IGBT are abnormal

5.

Whether soft start resistors or relay are abnormal

72

Relay Connect
Fail

Inverter relays are opened and cannot work or fuses are
broken.

73

Relay Short
Circuit

Inverter relays are shorted and cannot be released.

74

PWM Sync Fail

PWM synchronizing signal is abnormal

75

Intelligent Sleep

UPS works in intelligent sleep mode. In this mode, the
power modules will be standby in turn. It will be more
reliability and higher efficiency. It must be confirmed that
remained power modules’ capacity is big enough to feed
load. It must be conformed that working modules’ capacity
is big enough if user add more load to UPS. It’s
recommended that sleeping power modules are waken up if
the capacity of new added loads is not sure.

76

Manual Transfer
to INV

Manually transfer UPS to inverter. It’s used to transfer UPS
to inverter when bypass is over track. The interrupt time
could be over 20ms.

77

Input Over Curr
Tout

Input over current timeout and UPS transfer to battery
mode.

Please check if input voltage is too low and output load is
big. Please regulate input voltage to be higher if it’s
possible or disconnect some loads.

78

No Inlet Temp.
Sensor

Inlet temperature sensor is not connected correctly.

79

No Outlet Temp.
Sensor

Outlet temperature sensor is not connected correctly.

80

Inlet Over Temp.

Inlet air is over temperature. Make sure that the operation
temperature of UPS is between 0-40°C.

81

Capacitor Time
Reset

Reset timing of DC bus capacitors.

82

Fan Time Reset

Reset timing of fans.

83
