Description
The alarm name is user-defined, at most 10 letters. In this
system, eight DIs can be defined.
Load failure caused by overload, short circuit, manual
disconnect, or alarm circuit failure
Load failure caused by overload, short circuit, manual
disconnect, or alarm circuit failure
Controller hardware self-test failure
The system mode is set to 'Manual'
The battery is under float charge status
The battery is under testing status
The battery is discharging
In the system with load current shunt, the sampled load current
plus battery current differs greatly from rectifier current
The actual output voltage is different from both the measured
DC bus voltage and the voltage reported by the rectifier to
controller. The error is bigger than 1V
In short test, the battery discharging capacity is bigger than
setting value
The battery discharging time is shorter than expected time
Battery low voltage disconnects manually
Load1 low voltage disconnects manually
Load2 low voltage disconnects manually
Load3 low voltage disconnects manually
Load4 low voltage disconnects manually
All the AC input voltages from the rectifier are less than 80V
The load exceeds the set value
The controller has detected a reduction in the number of
running rectifiers
Time to maintain the system
More than two rectifiers alarm
The rectifier does not communicate with the controller
The input AC voltage of rectifier is lower than the under-voltage
point
The internal temperature of rectifier is higher than 90ºC
The rectifier is faulty
The rectifier performs self-protection and has no output
Rectifier fan failure
The rectifier limits its output power
Load sharing imblance between rectifiers
The rectifier over-voltage, higher than the limited setting voltage Major
The DC output voltage is lower than the setting of DC output
under-voltage alarm point
The DC output voltage is lower than the setting of DC output
under-voltage alarm point
