Table 10 Charger Faults and Warnings
* Faults will self-recover when the condition returns to normal range
•
Warm Battery
: The battery temperature has measured between 50°C and 59.9°C. The charger will reduce the
charge current to its minimum level.
•
High Battery Voltage
: There may be an issue with the vehicle’s alternator. Disconnect the inverter/charger
from the battery before examining the vehicle’s electrical system.
•
High Battery Temp
: The battery temperature exceeds 60.0°C, and the charger will shut down. The charger will
need to be restarted once the battery has cooled down.
•
Low Battery Voltage
: The battery voltage measured at the charger DC terminals has dropped below a
threshold, and the charger will shut down. The charger will need to be restarted once the battery voltage has
recovered.
•
High Temp Transformer
: The transformer temperature has exceeded its limit, and the charger will shut down.
The inverter will automatically restart once the inverter has cooled down.
•
High Temp Heatsink
: The internal heatsink temperature has exceeded the preset limit, and the charger will
shut down in high temp.
•
Zero Amp Limit Set
: The charger will turn off if the branch circuit rating (BCR) setting has been set to
zero. Setting this feature to zero limits the power that can be used for the charger to zero. Bypass power is still
available.
•
Overcurrent Shutdown
: The output has short circuited, and the charger will immediately shut down.
•
Disabled by CAN
: The charger has been turned off with a CAN command.
