2 Introduction
This instruction manual contains important information for safe operation of
the device. Make sure you read and follow the safety instructions provided.
The instruction manual should be kept in the vehicle at all times. Ensure that
other users are made aware of the safety regulations.
Use
The LR 1218 solar charge regulator is for charging the batteries of the motorhome by means of the connected solar module. The solar charge regulator limits and controls the charging voltage of the batteries. The solar charge
regulator can be connected to:
F
F
F
For vehicles with digital panel and solar current display, the charging current
is picked up by the shunt installed in the solar charge regulator and displayed as solar current on the digital panel.
The solar charge regulator works as a pulse-width modulated series regulator and ensures that the connected batteries are charged without being impaired.
Y
To use the solar charge regulator with an Electrobloc, see the instruction
manual for the Electrobloc.
3 Operation
The solar charge regulator does not have any controls.
Y
A TTENTION!
The output voltage of the charge regulator is not suitable for direct supply
without battery.
Malfunction of or damage to connected consumers:
two batteries
a Schaudt Electrobloc with a separate connection for solar current
a Schaudt Electrobloc with a retrofit adapter for charging the starter
battery
F
Do not operate the solar charge regulator without a battery.
F
Disconnect connector ”Plus
Solar module(s)” on the solar charge regulator before changing or removing the battery.
F
The solar charge regulator may only be used in buffer mode with lead
acid or lead gel batteries with a minimum rating of 55 Ah.
4 System faults
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 electronic bloc
repaired at a specialist workshop. Please note that the warranty will become
void if incorrect repair work is carried out. Schaudt GmbH shall not accept
liability for any damages resulting from such repairs.

6 Application and functions in detail
If the solar modules have sufficient charging voltage, the solar charge regulator allows the battery to be charged by up to 14.2 V.
As soon as these voltage is reached, the charging current is reduced to fully
charge the batteries without impairing them. If the charging voltage of the
solar modules is insufficient (e.g. in the dark), an integrated isolation diode
prevents the batteries from discharging.
Priority of the
living area battery
Living area battery and starter battery are charged simultaneously. The living
area battery has priority.
7 Maintenance
The device requires no maintenance.
Cleaning
4
Clean the device with a soft, slightly damp cloth and mild detergent. Never
use spirit, thinners or similar substances. Do not allow liquids to enter the
device.

Y
Not all parts/cables are required for every different application.
4 Mechanical installation
Y
This device is intended for installation into a vehicle.
The device is designed for wall or floor installation. For applications in sections 5.2 and 5.3, it must be installed in the direction vicinity of the EBL ...
electrobloc (at a maximum distance of 30cm to the front plate).
Environment
Minimum clearance
Fitting
"
For applications in which the cables supplied are used to connect to an
Schaudt EBL ... electrobloc, the solar charge regulator must be installed
in the direct vicinity of the electrobloc.
"
For other applications, a dry and sufficiently ventilated place in the insulated interior is to be selected for installation. No condensation may be able
to form on the device. In order to prevent a build-up of heat, ventilation
holes towards the living area must be provided in the upper and lower
areas of the place of installation. Its cross-section is based on the size
and average temperature of the place of installation.
"
Ensure a minimum clearance to the surrounding fixtures and fittings:
F
Maintain a gap of at least 5 cm on all sides (except mounted side).
F
Whilst in operation, the ambient temperature must not exceed +45 °C,
measured 2.5 cm away from the sides of the device.
"
On a stable and even surface, attach the solar charge regulator to the
drillholes with three screws (Fig. 1, Pos. 6).
