I Main charge with maximum 28 A charging current, electronically limi-
ted, up to final charging voltage. The battery is now charged up to ap-
prox. 80%. Start of charge also for completely discharged batteries.
Uo Automatic changeover to full charge with constant 14.4 V. The duration
of the full charge phase depends on the type of battery and is configu-
red on the device: Lead-acid batteries, 4 hour, lead-gel batteries, 16
hours.
U Automatic changeover to compensation charge with constant 13.7V. In
the compensation charge phase, the voltage at the output of the char-
ging module is constant. The battery is now charged up to approx.
95%.
Start of a new charging cycle by switching over to main charge, if the battery
voltage falls below 13.7V for more than 5 seconds when loaded. Start of
charge also for completely discharged batteries. The internal charger mo-
dule can also be operated without the caravan battery.
