3 Operation
The Electroblock is operated solely from the DT/LT ... control and switch
panel connected to it and via the ST ... control panel (if fitted).
The EBL 220-4 Electroblock does not require daily operation.
Initial setting is only needed after the type of battery (lead-acid or lead-gel)
has been changed or during commissioning or when upgrading with acces-
sories (see Chapter 3.2 and installation instructions for details).
3.1 Starting the system
Y ATTENTION!

The connected devices will be damaged. Therefore prior to starting:
F Make sure the living area battery is connected.
F You must ensure that the battery selector switch (Fig. 3, Pos. 11) is
set to the correct position for the type of battery being used.
F You must ensure that the AES fuse (Fig. 3, Pos. 6) is only inserted if
an AES refrigerator is connected to the system. Otherwise, the living
area battery may get totally discharged. Battery damage is possible.
F You must ensure that the switch for the number of auxiliary chargers
(Fig. 3, Pos. 18) is set in the correct position.

Y ATTENTION!
Permitted input voltage exceeded!
Will damage the consumers connected to the system:
F Never run a solar charger supplied by Schaudt without a battery being
connected to the system.
F Unplug the “+ solar-cell” connector on the solar charger first if the
battery is going to be changed or removed.
³The living area battery must be fully charged before closing the system
down.
The living area battery is then protected against total discharge. This applies
only if the battery is intact. Follow the instructions of the battery manufactu-
rer. The shut down system requires approx. 4 Ah a month.
Disconnect the living area battery from the 12 V power supply if you are not
going to use the motorhome for a lengthy period (i.e. during the winter). The
system is equipped with a battery isolator that completely isolates the living
area battery (electrically) from the vehicle. Battery isolation is activated from
the DT/LT ... control and switch panel (see DT/LT control and switch panel
instruction manual).
³12 V main switch on the DT/LT ... control and switch panel must be
switched off.
³Activate battery isolation on the DT/LT ... control and switch panel.
³Pull out the fuse for the AES refrigerator.
Y The living area battery can also be charged using the internal charger
module, an auxiliary battery charging unit, the solar charger and the alter-
nator when the battery isolation is activated.
³The living area battery must be fully charged before closing the system
down.
³Remove the clamps from the battery terminals.
³Remove the “+ solar-cell” connector on the solar charger.

4 Application and function
The Elektroblock EBL 220-4 A and EBL 220-4 with OVP is the central power
supply unit for all 12 V consumers connected to the electrical system of the
motorhome or caravan. It is normally fitted inside a cabinet or a stowage
space and can be accessed from the front to change a fuse.
The electroblock EBL 220-4 with OVP is suitable for all cases of application
in which the danger of overvoltage is especially large. This can e. g. be
lightning strikes in the public mains, generator operation, bad electronic
installations or trips to foreign countries.
For this in the electroblock an overvoltage protection is fitted in internally
between the mains connection and the loading module.

4.1 Battery functions
6-cell lead-acid or lead-gel batteries from 55 Ah upwards
Simultaneous starter battery and living area battery charging via alternator,
parallel battery switching via an isolation relay
Battery isolation (activated from the DT/LT ... control and switch panel) cuts
off the following connections from the living area battery:
F All 12 V consumers
F The frost protection valve
This prevents the living area battery from being slowly discharged by closed-
circuit current whilst closing down the vehicle.
The batteries can still be charged using the Electroblock, the alternator, an
auxiliary charging unit or the solar charger, even when the battery isolation is
activated.
The switching option provided by the battery selector switch ensures opti-
mum charging of the two different types of battery, lead-acid and lead-gel.
The battery monitor of the control and switch panel DT/LT ... with dynamic
voltage wave continuously monitors the living area battery. It switches off
“earlier” with small discharge currents than with large ones. This enhances
the total discharge protection. Monitoring also occurs when the device is
switched off. Depending on the current consumption, a warning message is
displayed once the value falls below 12 V.
If the living area battery voltage continues to drop and falls below 10.5 V, the
battery monitor immediately switches off each 12 V consumer. The control
and switch panel also switch off automatically. Only the anti--freeze valve is
still supplied with current to ensure that it remains closed. Prior to shutdown,
all the switching states and the battery capacity value are stored and
restored after switching on.
If an overload or an insufficiently charged living area battery causes the vol-
tage to fall so low that the automatic disconnection is triggered, any consu-
mers which are not essential should be switched off.
