Error LED:
The LED indicator has two states:
ON CONTINUOUSLY - Indicates that power has been switched
on 1 to 3 seconds ago but the MCU software has not started yet.
The MCU software will turn off the LED once it has started.
FLASHING - Indicates that there is an error in the charge
process. The software has stopped charging and the MCU draws
its power from the external DC supply.
Full LED:
When this LED is ON, the DC/DC Converter is in FLOAT
CHARGE state. The 12 V system battery is full and battery
charging is complete. There is no battery charge current. The
battery voltage is floating at the temperature compensated level.
Compensation is done in software and it is based on the Processor
Board temperature sensor unless otherwise configured.
Charging LED:
This LED indicator has two states:
ON CONTINUOUSLY - The DC/DC Converter is in BULK
CHARGE - state and the battery is being charged at maximum
current.
FLASHING - The DC/DC Converter is in BULK CHARGE state,
but the available charge current is limited due to the supply line
impedance or otherwise. For example charge takes place, but not
at full power.
AC ON LED:
This LED indicates that there is an external voltage present at
the AC IN terminals of the MCU Frame.
