•
Do not place the charger on the battery while charging.
•
The electrical connection must full the national heavy current requirements.
•
Check the charger cabling before use. Make sure there are no cracks in the cabling or in the protective covering. A charger with
•
damaged cables may not be used.
Always check that the charger has gone over to maintenance charging mode before leaving the charger unattended and
•
connected for long periods. If the charger had not gone over to maintenance charging within 3 days, this is an indication of a
problem. In this case the charger must be disconnected manually.
All batteries fail sooner or later. A battery that fails during charging is normally taken care of by the chargers advanced control,
•
but certain uncommon errors in the battery can still arise. Don’t leave the battery charger unattended for a longer period of time.
Only mount the charger on a at surface.
•
This equipment may not be used by children or by those who can not read and understand the manual if they are not supervised
•
by a responsible person who can guarantee that the battery charger is being used in a safe manner. Store and use the battery
charger out of the reach of children. Make sure that children do not play with the battery charger.
When using outdoors the charger has to be positioned horizontally with the long side or top side turned up.

CHARGING
Connecting the charger to a battery tted in a vehicle
1. The power cord should be disconnected when connecting or disconnecting the battery leads.
2. Identify the battery terminal that is grounded (connected to the chassis). The negative terminal is normally the grounded post.
3. Charging a negatively grounded battery. Connect the red cable to the positive terminal on the battery and the black cable to
good metal engine ground away from the battery. Ensure you do not connect the black cable to fuel lines or sheet-metal body
parts.
4. Charging a positively grounded battery. Connect the black cable to the negative terminal on the battery and the red cable to
good metal engine ground away from the battery. Ensure you do not connect the red cable to fuel lines or sheet-metal body parts.
Connecting the charger to an out of vehicle battery:
1. The power cord should be disconnected when connecting or disconnecting the battery leads.
2. Connect the red cable to the positive terminal on the battery and the black cable to the negative terminal.
If the battery leads have been connected incorrectly, the reverse polarity protection system will ensure that neither the charger nor
the battery are damaged.
Start charging
1. Connect the chargers AC cord to an AC Power Supply. The charger will indicate POWER, yellow indication lamp (B).
2. The lamp for completely discharged battery (1) will illuminate if the battery’s voltage is less than 12V for MULTI XS 25000 and
XS 25000 or 24V for MULTI XT 14000 or XT 14000.
3. Normal charging
charging (3) or maintenance charging (4). When the maintenance charging lamp illuminates the battery is fully charged. Charging
will start if the voltage drops. The charger can normally be connected for months. Reconditioning (only on MULTI XS 25000 and
MULTI XT 14000) is indicated by the lamp (5) illuminating.
4. If the battery leads have been connected incorrectly, the reverse polarity protection system will ensure that neither the charger
nor the battery are damaged.
5. If nothing happens. If the lamp indicating the setting and the power lamp remain lit but no other lamp illuminates, the connection
to the battery or chassis may be poor or the battery may be faulty. Another cause may be a lack of voltage in the AC Power Supply.
Begin by improving the connection between the battery and charger.
will be indicated by the following lights: completely discharged battery (1), bulk charging (2), absorption

6. Charging can be stopped at any time by disconnecting the charger’s AC cord. Always disconnect the AC cord before
disconnecting the battery leads. When you stop charging a battery installed in a vehicle you should always disconnect the battery
lead from the chassis before disconnecting the other battery lead.
IMPORTANT INFORMATION FOR MULTI XT 14000 AND XT 14000
Please note that the battery pack in the 24V system in most cases consists of more than one battery. They are linked up to the
24V system, but the individual batteries generally have a lower voltage. Therefore it is important for the charger to be connected
correctly.
BATTERY TYPES AND SETTINGS
The XS 25000 and XT 14000 are programmed according to “PROGRAM DESCRIPTION” with xed settings. MULTI XS 2500 and
MULTI XT 14000 can easily be set for different types of batteries or conditions. The following recommendations should, however,
only be seen as guidelines. Please consult the battery manufacturer for further instructions.
Settings are made by pressing the “MODE-button “ and stepping forward one press at a time until the required mode is reached,
the button is then released. After about 2 seconds the charger activates the selected mode. The selected mode is saved in a
memory in the charger and remains there even if the charger is disconnected from battery and mains.
NORMAL
SUPPLY
RECOND
NORMAL - Normal setting for wet batteries, maintenance free and for most Gel batteries. Some Gel batteries
prefer a slightly lower charging voltage. Please consult the battery manufacturer when in doubt.
SUPPLY - The charger operates at a constant voltage. This is the maintenance mode for applications where
maximum capacity from the battery is important, like oor sweepers and golf carts. Note that the Spark
protection function is suppressed in this mode.
RECOND - This mode is used to recover deep discharged ooded batteries where you could expect a
stratied acid (high acid weight in the bottom, low on top). Check with battery manufacturer when in doubt.
Use this mode with care, because the high voltage will cause some water loss. 16V is normally no problem for
electronics in 12V system, or 32V in 24V system. Consult your supplier when in doubt. Life of light bulbs will
be reduced at higher voltage. Try to disconnect light from the battery during this phase. Maximum effect and
minimum risk for electronics is achieved by charging a disconnected battery.
CHARGING PHASES
MULTI XS 25000, XS 25000, MULTI XT 14000 and XT 14000 charges and analyses in eight fully automatic steps.
MULTI XS 25000 and MULTI XT 14000 have three different operating modes, see Battery Types and Settings.
The battery charger has an 8-step fully automatic charging cycle:
Desulphation
Desulphation with pulses recovers sulphated batteries. Indicates with lamp 1.
Soft start (Lamp 1)
Start mode for the charging cycle. The start phase continues until the battery’s terminal voltage has risen above the set limit, at
which point the charger switches to bulk charging. If the terminal voltage has not passed the voltage limit within the time limit, the
charger switches to fault mode (lamp 0) and discontinues the charging. If so, the battery is faulty or its capacity is too large.
Bulk (Lamp 2)
Main charge when 80% of charging takes place. The charger delivers maximum current until
set level. Bulk has a maximum time, at which point the charger automatically switches to Absorption.
Absorption (Lamp 3)
Complete charge up to virtually 100%. The terminal voltage is maintained at the set level. During this phase the current tapers successively. Once the current has tapered to the set limit, this phase switches to being timed. If the total time for Absorption exceeds
the time limit the charger automatically switches to maintenance.
Analysis (Lamp 3)
Testing self-discharge. If self-discharge is too high, charging is discontinued and fault mode is indicated.
Maintenance charging - Float (Lamp 4)
Charging at constant voltage.
Maintenance charging - Pulse (Lamp 4)
State of charge varies between 95% and 100%. The battery receives a pulse when the voltage drops and keeps the battery in
perfect condition when it is not in use. The charger can be connected for months at a time. The charger continuously measures
the terminal voltage to determine whether a charging pulse should be initiated. If the battery is loaded and/or the battery’s terminal
voltage drops the charger starts a charging pulse until the terminal voltage reaches the set level. The charging pulse is then
discontinued and the cycle is repeated innitely. If the terminal voltage drops below a lower limit, the charger automatically goes
back to the beginning of the charging curve.
