Different charging characteristics can be set with two battery selector swit-
ches for the perfect charging of different battery types. Temperature com-
pensation of these charging characteristics is realised with (optional) tempe-
rature sensor affixed to the battery, and results in additional optimisation of
battery charging at maximum battery protection.
The LAS 1218 BUS battery charger is aligned perfectly to Schaudt bus sy-
stems, and a corresponding connection to the SDTBUSlinks the device
into the system. This enables fully-automatic control of the entire charging
process with all chargers and batteries connected.
The LAS 1218 BUS battery charger is also excellently suited in conventional
systems and as standalone chargers.
YThis device is not intended to be used by those (including children) with
limited physical, sensory or mental aptitude or lack of experience and/or
knowledge unless they are supervised by a person responsible for their
safety or have received instruction from this person as to how the device
is used.
YChildren are to be supervised so as to ensure they do not play with the
device.
YThis device is intended for installation into a vehicle.
The device is a primary controlled switch-mode power supply unit. This mo-
dern switching technology achieves high charging performance at a compact
size and low weight.
The battery charger can be used:
Fas a battery charger for charging the leisure area battery and for re-
charging a connected starter battery
Fas an auxiliary charger for loading leisure area batteries with higher
capacities, suitable for every Schaudt EBL electroblock with an LAS
charger module (the possible number of auxiliary chargers depends
on the number of auxiliary charger connections on the respective
EBL)
Fas an auxiliary charger for charging leisure area batteries with higher
capacities, suitable for every SDTBUS-capable Schaudt EBL ...
electroblock (up to two auxiliary chargers can be connected here)
Fas a power supply unit (up to 18 A) for the 12V consumers connected.

1.3 Operation
1.3.1 Controls and indicator LEDs
The device has no controls which need to be used on a day-to-day basis.
The battery selector switches need only be set correctly on initial use and for
a change of battery.
YDANGER!
Risk of explosion!
FAn incorrect battery selector switch setting poses a risk of explosion
due to the formation of electrolytic gases.
YATTENTION!
FAn incorrectly set battery selector switch will damage the leisure area
battery.
FDisconnect the battery charger from the mains before moving the bat-
tery selector switch.
The LAS 1218 BUS charger may have to be reset when a battery type is
changed (see also Page 18).
Batteries may only be replaced by qualified personnel.
Follow the battery manufacturer’s instructions.
Charging unsuitable types of battery may damage them beyond repair.
It is possible to swap lead acid batteries with lead gel batteries.
Given the lack of ventilation options within the vehicle, changing from lead
gel to lead acid batteries is not possible without additional overhead.
Ask your dealer for advice.
The switching option provided by the battery selector switch ensures opti-
mum charging of the different battery types (lead-gel, lead-acid and AGM).
The indicator LEDs on the front of the battery charger show the current char-
ging phase.
This indicator LED lights up yellow in the ”Main Charge” and ”Full Charge”
phases.
This indicator LED lights up green in the ”Trickle Charge” phase.
YIn supply mode, the two LEDs switch alternately every second.

230V units carrying mains voltage.
Risk of fatal injury due to electric shock or fire:
FOnly carry out electrical work once the 230V supply has been discon-
nected.
The mains must be connected as follows:
Fto a insulated distribution unit with protective contact
Fto a socket with protective contact (isolated ground or suitable plug
connector from WAGO, depending on LAS 1218 BUS variant).
The power cord must be of type H05VV-F 3x1.5.
The mains cable must have a strain relief where required.
2.4 Initial use
2.4.1 Checks prior to initial use
Ensure that the batteries are connected properly (only for initial use, ope-
ration without battery is possible in general).
2.4.2 Setting battery type
Determine the battery type
YDANGER!
Incorrect setting of the battery selector switch.
Risk of explosion from build-up of electrolytic gas, defective battery, defec-
tive battery charger or as a result of too high a battery operating tempera-
ture (above 305 C):
FMove the battery selector switch to the correct position.
Store batteries in a place that is sufficiently ventilated (or provide integra-
ted ventilation). Follow the instructions provided by the battery manufac-
turer.

Disconnect the battery charger from the mains before moving the battery
selector switch.
YHowever, suitability must be checked using information from the battery
supplier and the charging parameters of Schaudt equipment. The char-
ging parameters are specified in the operating and installation instruc-
tions.
Move the battery selector switch (see Fig. 8) to the correct position using
a thin object, such as a ball point pen:

YIn supply mode, the charge regulator supplies a constant output voltage
YThe two switches are recessed in the housing to eliminate incorrect ope-
ration. A small screwdriver may have to be used to switch setting.
Then re-check that the battery selector switch is in the correct position for
the type of battery used.
2.4.3 Setting the address
When a LAS 1218 BUS is used in Schaudt bus systems, every device con-
nected to the SDTBUShas an ”address”.
Set the ”Auxiliary charger” address switch as follows:
One LAS 1218 BUS battery charger as an auxiliary charger:
Move the ”Auxiliary charger” switch to Pos ”1”
Two LAS 1218 BUS battery chargers as auxiliary chargers:
Move the ”Auxiliary charger” switch on one device to Pos ”1”
Move the ”Auxiliary charger” switch on the other device to Pos ”2”
The switch position is not important when the LAS 1218 BUS battery char-
ger is used in conventional systems.
2.4.4 Starting up the system
Ensure that the battery is connected correctly (or all if more than one is
available).
230V mains supply must be connected to vehicle.
Switch on the electrical system of the vehicle (e.g. turn on the main 12V
switch on the control panel -- refer to the operating instructions for the
control panel connected).
230V mains cable of the LAS 1218 BUS charger must be connected (the
charger does not have its own mains switch).
