Description
Battery Period Testing
The battery is undergoing the automatic, periodic battery maintenance test
(20% capacity discharge)
Batt. Capacity Testing
The user has initiated a battery capacity test (100% capacity discharge)
Batt. Maint. Testing
The user has initiated a maintenance test (20% capacity discharge)
Batt. End of Discharge
Inverter switched off due to battery EOD
Battery Overtemp.
The battery temperature is over limit
Low Battery Warning
Before the EOD, battery low pre-warning will occur. After this pre-warning, the
remaining battery capacity will be sufficient for another 3 minutes at with full
load. This interval may be set-up by the user to between 3 and 6 minutes
On Generator
Dry contact signal, indicating generator connected
Battery Maintain
Battery test failed, service or replace the battery
Battery Ground Fault
Battery ground fault
Batt. Room Temp. Abn.
Battery room over temperature (option included)
BCB1 Status Abnormal
Logic conflict between BCB1 driver signal and feedback signal
BCB1 Closed
BCB1 state (closed)
BCB1 Open
BCB1 state (open)
Mains Fuse Failure
At least one mains fuse has blown, and the rectifier is disconnected
Bypass Fuse Failure
At least one bypass fuse has blown, and the system transition to bypass is
disabled
Output Fuse Failure
At least one output fuse has blown, the inverter is disconnected, and the
system is in Bypass mode
Equalize Chg. Timeout
The actual float charging time exceeds the time set-up by the configuration
software
MonCAN Comm. Abnor.

rectifier and bypass
ParaMonCANComm.Abnor.
Communication failure between racks
PowerCAN Comm. Abnor.
Communication failure between inverter, rectifier and bypass
ParaPowerCANCommAbnor.

LBS Cable Abnormal
The LBS cables are not connected correctly, or they are damaged
Capacity Exceeded
System overload
Loss of Redundancy
Loss of redundant capacity
Pwr. Hardware Mismatch
The model information set-up on the host is inconsistent with the actual
situation
Module Overtemp.
Over-temperature condition on the rectifier and inverter power components
inside the module
Charger Overtemp.
Over-temperature condition on the charger power components inside the
module
Equalize Chg. Timeout
The current float charging time exceeds the time set-up using the
configuration software
MonCAN Comm. Abnor.
