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

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

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

RECOND - This mode is used to recover deep discharged ooded batteries where you could expect a

stratied 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 the terminal voltage has risen to the

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 suc-

cessively. 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 innitely. If the terminal voltage drops below a lower limit, the charger automatically goes

back to the beginning of the charging curve.
