1 Introduction
This instruction manual contains important information for the safe operation
of equipment supplied by Schaudt.
The operating instructions should always be kept in the vehicle.
YATTENTION!
Failure to comply with the sign may result in damage to equipment or other
connected loads.
2 Application and function
The LT 100 control panel is the central console for electroblock EBL ... /
CSV ... supplying all 12V consumers in the electrical system on board the
motorhome. It is usually installed in an easily accessible place high up near
the door of the vehicle.

Fig. 1 On-board power supply system
The main layout of the on-board vehicle electrical system is shown in Fig. 1.
The functions of the LT 100 control panel is to switch on and off the 12V
supply to the caravan, and to display the battery voltage, the tank levels and
the connection to the mains supply (230 V).
An EBL ... / CSV ... power supply must be connected for operation. This pro-
vides the 12V supply to the caravan devices and charges the battery.
The following connection options are available:

The LT 100 control panel has touch-sensitive sensors. These sensors react
when touched with a bare finger. The LT 100 control panel cannot detect
touches when gloves are worn (such as for camping in winter). Gloves must
therefore be removed before use.

3.2 Starting up
"Switch on the LT 100 control panel (see Section 3.3).
"Connect the input to the mains supply of the vehicle to the 230V mains
supply.
Mains indicator LED lights up. The leisure area battery is being charged. For
details on the charge functions, refer to the operating instructions for the re-
levant power supply (EBL ... / CSV ...).
3.3 Switching on
The 12V supply of the vehicle is switched on from the relevant button. The
refrigerator controller is an exception. It also works when the 12V power
supply is switched off -- refer to the operating instructions for the relevant
power supply (EBL ... / CSV ...).
"Touch the sensor for the main 12V ON/OFF switch
FThe green indicator LED lights up
FThe 12V leisure area supply is switched on
YWhen the LED “11.0 V” flashes, the supply voltage cannot be switched on,
because the battery voltage ist too low (battery alarm, see chap. 3.6.1).
3.4 Checking the battery voltage
"Touch the sensor for the Check leisure area battery voltage:
FRed LED lights up: Battery voltage above 11.0V
FYellow and red LEDs light up: Battery voltage above 12.2V
FRed, yellow und the lower green LEDs ligt up: Battery voltage above
12.7V
FAll LEDs light up: Battery voltage above 13.5V
The following table shows the correct interpretation of the voltage of the lei-
sure area battery displayed on the scale.
These values apply to actual operation, not off-load voltage.

YATTENTION!
Total discharge results in damage to the leisure area battery:
FA low battery charge, indicated by low voltage, must be prevented.
FSwitch off some consumers in the event of overloaded power supply.
FPrior to taking the vehicle out of service, ensure that no inactive con-
sumers are still connected.
Measuring the off-load voltage is a simple and effective method of checking
the condition of the battery. Off-load voltage is the voltage of the charged
battery in a passive state, with no current being supplied or drawn.
Take the measurement several hours after the last charging. In the mean-
time, no significant load should be placed on the battery, meaning no current
should be drawn from it. There is a risk of total discharge if the off-load vol-
tage of the battery is 12.2V or lower.
The following table shows the correct interpretation of the off-load voltage
displayed. The values specified are guidelines for gel batteries.
Values for off-load voltage Charge state of the battery
11.5V or lower totally discharged
12.2V Approx. 25%, discharged or almost
exhausted

FThe level of the relevant tank is displayed:
-- Water: 100%, 75%, 50%, 25%;
The tank is empty if the 25% LED flashes.
-- Waste water: 100%, 75%, 50%, 25%
The tank is full if the 100% LED flashes.
3.6 Troubleshooting and remedies
3.6.1 Alarms
YATTENTION!
Total discharge results in damage to the leisure area battery:
FA low battery charge, indicated by low voltage, must be prevented.
FCheck the voltage regularly (see Section 3.4)
YIt is best to carry out checks in the morning before 12V consumers are
switched on.

sure area battery.

3.6.2 Faults
The majority of power supply system faults are caused by blown fuses (refer
to the instruction manual for the relevant EBL ... / CSV ... power supply for
information on voltage distribution and fusing).
Please contact our customer service team if you cannot rectify a fault using
the following table.
If this is not possible (such as when you are abroad), you can have the elec-
trical vehicle system 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.

3.8 Closing down the system
The system should be switched off if the vehicle is not being used for a leng-
thy period, such as during the winter.
"Disconnect the leisure area battery from the 12V on-board supply; to do
this:
"Disable the battery cut-off switch of the relevant power supply
or
"Disconnect the battery terminals (depending on power supply)
YAlso refer to the operating manual for the relevant power supply (EBL ... ,
CSV ...)
