Instruction Manual for Electroblock EBL 30 / EBL 30 with OVP

2 Introduction

This instruction manual contains important information on safe operation of
the device. Make sure you read and follow the safety instructions provided.

The operating instructions should always be kept in the vehicle. All safety in­formation must be passed on to other users.

3 Operation

The electroblock is operated solely via the IT ... / LT ... control and switch
panel connected. .

For daily use, no operation is needed on the EBL 30 electroblock (excep­tion: the battery cut-off switch should be disabled when the vehicle is not in
use, see Section 3.4).

One-off adjustments only have to be made if the battery type is changed
(lead-gel or AGM), during initial start-up or when retrofitting accessories (see
Section 3.2 and the installation instructions for the EBL 30).

Overvoltage protection

OVP

3.1 Starting up the system

The EBL 30 with OVP electroblock is suitable for all applications in which the
risk of overvoltage is particularly high. For example, lightning strikes on the
national grid, generator operation and poor electronic installations at cam­ping sites.

For this, an overvoltage protection unit is fitted in the electroblock between
the mains connection and the charge module. In the event of over or under­voltage, this overvoltage protector isolates the electroblock from the 230V
supply within just a few milliseconds. It remains cut off until the main voltage
has normal values again.

Y ATTENTION!

Incorrect electroblock settings.
Damage to connected devices. Therefore prior to starting:

F Ensure the leisure area battery is connected.

F Ensure that the battery selector switch (Fig. 4, Pos. 10) is set to the

correct position for the battery installed.

" Move the battery cut-off switch (see Fig. 4, Pos. 12) to the ”Battery ON”

position.

" Use the main 12V switch (see instruction manual of relevant control and

switch panel) to switch on/off all the consumers and the control and
switch panel.

8110305 BA / EN

The following outputs are exceptions:

F Floor light/step

F Heater

F Frost protection valve

F AES/compressor refrigerator

F Floor light 4A

F Floor light 4B

These outputs are not disabled from the main switch of the IT ... / LT ... con­trol and display panel.

Please refer to the operating instructions of the IT ... / LT ... control and
switch panel for further information. .

3.2 Changing the battery

Y ATTENTION!

Use of incorrect battery types or incorrectly rated batteries.
Damage to the battery or devices connected to the electroblock:

F Batteries may only be changed by qualified personnel.

F Follow the battery manufacturer’s instructions.

F Only use the electroblock to connect to 12V power supplies with re-

chargeable 6-cell lead-gel or AGM batteries. Do not use any unsuita­ble battery types.

Y Normally only batteries of the same type and capacity should be used,

i.e. the same as those installed by the manufacturer.

Changing the battery

" Electrically isolate the battery from the electroblock. For this, switch off

the battery separation switch on the EBL 30 electroblock (refer also to
Section 3.4).

" Replace the battery.

" After changing the battery, recheck which type of battery has been inser-

ted.

Y DANGER!

Incorrect setting of the battery selector switch.
Risk of explosion due to build up of explosive gases:

F Move the battery selector switch to the correct position.

" Disconnect the electroblock from the mains before adjusting the battery

selector switch.

Fig. 1 Battery selector switch

"

Move the battery selector switch (Fig. 1, Pos. 1) to the correct position
using a thin object (e.g. a ballpoint pen):

F Lead-gel battery: Move the battery selector switch to ”Gel”.

F AGM battery: Move the battery selector switch to ”AGM”.

Starting up

" Start up the system as described in Section 3.1.

3.3 Faults

Flat vehicle fuses

Discharged battery --

start motor

A flat battery or defective fuse is the cause of most faults in the power sup­ply system.

If the battery is discharged, consumers can always be powered by starting
the engine of the base vehicle.

Please contact our customer service address if you cannot rectify the fault
using the following table.

If this is not possible, e.g. if you are abroad, you can have the electroblock
repaired at a specialist workshop. In this case, you must ensure that the
warranty is not invalidated by incorrect repairs being carried out. Schaudt
GmbH will not accept any liability for damage resulting from such repairs.

Damage to the leisure area battery:

F Fully charge the living area battery before and after closing down the

system. (Connect vehicle to the mains with an 80Ah battery at least
12 hours and with a 160Ah battery at least 24 hours).

Disconnect the living area battery from the 12V power supply if the motor­home is not used for a longer period (during the winter for example).

" Fully charge the living area battery before closing down t he system.

" Switch off the main switch on the IT ... / LT ... control and display panel.

" Move the battery cut-off switch (see Fig. 4, Pos. 12) to the ”Battery OFF”

position. The following connections are isolated from the living area bat­tery:

F All 12V consumers

F Frost protection valve

F Operator and control panel

The living area battery is then protected against total discharge. This only
applies if the battery is intact. Follow the battery manufacturer’s instructions.

Y If the living area battery is isolated from the electroblock with the battery

cut-off, the frost protection valve of the combination heater opens. A loss
of water is possible (see the operating instructions for the combination
heater).

These devices control the electrical functions in the vehicle’s living area, inc­luding accessories.

There is also an option to connect an additional charger and a solar loading
regulator.

Flat vehicle fuses protect the various circuits. The D+ output is an exception.

Automatic disconnector

6-cell lead-gel or AGM batteries, 55 Ah and above

Simultaneous charging of the starter battery and the living area battery via
the alternator, parallel connection of the batteries via a cut-off relay

Maximum permitted charge current 14 A, fused with 15 A (for leisure area
battery), simultaneous charging of the starter battery

The battery is isolated with the battery cut-off switch.

This prevents the living area battery from slowly discharging due to closed
circuit current while the vehicle is not in use.

The switching option provided by the battery selector switch ensures opti­mum charging of the battery types, lead-gel and AGM, for mains supply.

The battery monitor compares the current of the living area battery with a
reference current. As soon as the battery current drops below 10.5V , all 12V
consumers are switched off via main switch relays 1 and 2.

Only the frost protection valve continues to be powered.

The automatic disconnector is not triggered by short-term low voltage (shor­ter than 2 seconds), caused by high current when switching on consumers.
If an overload or an insufficiently charged living area battery causes the vol­tage to fall so low that the automatic disconnector is triggered, any non-es­sential consumers should be switched off.

If need be, the 12V supply can begin operation for a short time. For this,
switch on the 12V main switch on the control and switch panel.

However, if the battery current remains below 11.0V, the 12V supply can not
be switched on again. Fully charge the living area battery as soon as possi­ble. For more information, see the description of ”battery voltages”.

This relay supplies the AES/compressor refrigerator with power from the
starter battery when the vehicle engine is running and the D+ connection is
live. An AES refrigerator is powered by the living area battery when the vehi­cle engine is not running.

This feature provides an automatic max. 6 A float charge for the starter bat­tery when the 230V mains is connected to the electroblock.

The electroblock is isolated from the mains within 10ms in the event of a
voltage greater than 265 V
