Improper use

Do not use for 6 V batteries or non-chargeable
batteries!
The automatic charger may not be used to charge 6 V lead ac-
cumulators. If batteries with a rated voltage of 6 V are charged
with the automatic charger, gassing occurs immediately
which creates an explosive detonating gas.
The automatic charger may not be used to charge non-
chargeable batteries and / or nickel-cadmium batteries.
If the automatic charger is used to charge these batteries, the
case can burst explosively.

Description

The automatic charger contains state-of-the-art microproces-
sor-controlled charging technology. This technology allows
high performance whilst remaining lightweight and small.
Thanks to the top quality electronics, it works highly efficient-
ly. The automatic charging process is gentle to the battery and
prevents damaging overcharging, which in turn significantly
extends the service life of the battery. After the battery and
mains supply have been connected, the automatic charger is
ready for use.
The automatic charger is designed for continuous operation
and parallel mode. Consumers can be continuously connect-
ed, switched on or disconnected. Consumers are supplied and
the battery charged at the same time. The consumer current
here should be smaller than the maximum charging current as
otherwise the battery will not charge.
Using a charging control panel, e.g. the Truma Panel BC (430,
630, 860), the individual charging phases of the supply battery
(battery II) and the starter battery (battery I) can be displayed.
Also, any malfunctions of the automatic charger are shown on
the Truma Panel BC (430, 630, 860).
If the automatic charger is operated in conjunction with a
temperature sensor for the battery, the automatic charger
regulates the charging current automatically depending on the
operating temperature. This ensures particularly effective and
gentle charging of the battery. If a temperature sensor is not
used, the automatic charger regulates the charging process in
the same way as a battery temperature of 20 °C.
The device is designed for operation in an ambient tempera-
ture of up to 35 °C. If the temperature inside the device in-
creases due to a lack of circulating air or due to the fact that
the ambient temperature is too high, the charging current is
automatically reduced gradually.

Charging process

Supply battery (battery II)

The automatic charger has an electronic reverse battery pro-
tection. The charging current is only released if the battery is
correctly connected and there is a minimum voltage of 1.5 V.
While it is being charged, the battery voltage is monitored
constantly by way of the B+ measuring line. The charging
process is carried out in accordance with the charging refer-
ence line with a minimum of performance loss. (Charging ref-
erence line, see fig. 2).
Main charging phase
(all voltage values relate to a battery temperature of 20 °C)
Charging with maximum constant charging current until a bat-
tery voltage of approximately 14.4 V is reached. If in this range
of the main charging phase, the charging current falls below
90 % of the rated current due to internal battery resistance
and resistivity, the afterloading phase is started.
Afterloading phase
(all voltage values relate to a battery temperature of 20 °C)
The charging voltage is kept at a constant 14.4V for a period
of 10 hours for gel/AGM batteries or four hours for liquid
electrolyte batteries. At the end of this period, it changes to
the trickle current phase. If during this period, the current
increases to over 90 % of the rated current and if at the same
time the battery voltage drops to below 13.2 V for a period of
more than 15 minutes for liquid electrolyte batteries and more
than two hours for gel batteries and AGM, it switches back to
the main charging phase.
Trickle charging phase
(all voltage values relate to a battery temperature of 20 °C)
The charging voltage is set to 13.8 V. The charging current
drops to the equalizing charge value necessary for the bat-
tery. If due to the consumer, the charging current increases
to its rated value and if the battery voltage drops for at least
2 minutes below 13.2 V, the device switches back to the main
charging phase.
Parallel mode
If consumer current is used during the aftercharging phase or
the trickle charging phase, this is immediately recharged.
