CHARGING

Connecting the charger to a battery t ted in a vehicle

1. The power c ord should be disc onnected when c onnecting or dis connecting the battery leads.

2. Ident ify the batt ery termina l that is grounded (connected to t he chassis). The negative

terminal is normally the grounded post.

3. Charging a negatively grounded battery. Connect th e red cable to the po sitive terminal o n the

batter y and the black cable to good meta l engine ground a way from the bat tery. Ensure you do
not connect the black c able to fuel lines or sheet-metal body part s.

4. Charging a positively grounded batt ery. Connect the black cable to the negative terminal on

the battery and the red cable to good m etal engine ground away from the battery. Ensure you
do not connect the black c able to fuel lines or sheet-metal body parts.

Connecting the charger to an out of vehicle b attery:

1. The power c ord should be disc onnected when c onnecting or dis connecting the battery leads.

2. Connect the red cable to the positi ve terminal on the battery an d the black cable to the

negative terminal.

If the bat tery leads have been connected incorrect ly, the reverse polarity protection system will
ensure th at neither the charger nor the battery are da maged.

Star t charging

1. Connect the charger´s AC cord to the power out let. The charger w ill indicate POWER, yellow

indication lamp (B).

2. The lam p for complete ly discharge d battery (1) will illuminate if the battery’s voltage is less
than 12V.

3. Normal charging will be indicated by t he following lights: completely discharged battery (1),
bulk char ging (2), absorptio n charging (3) or maintenance charging (4). When the maintenance
charging lamp illuminates the batter y is fully charge d. Charging will st art if the voltage drops.
The char ger can norma lly be connected for months. Recondition ing is indicated by the lamp (5)
illuminating.

4. If the bat tery leads have be en connected incorrectly, the reverse polarity protecti on system
will ensure that neither t he charger nor the battery are d amaged.

5. If nothing happens. If th e lamp indicat ing the setting and the power lamp remain lit but no
other lam p illuminates, t he connection t o the battery or chassis may be p oor or the batter y may
be fault y. Another cause may be a lack of volta ge in the AC Power Supply. Begin by improv ing
the connection between the battery and charger.

6. Charging can be stoppe d at any time by disconnecting the charger’s AC cord. Always disc on­nect the AC cord before disconnecting the batter y leads. When you sto p charging a bat tery
installed in a vehicle you should always disconnect the battery lead from the chas sis before
disconnecting the ot her battery lead.

BATTERY TYPES AND SETTINGS

The MULTI XS 150 00 can easily b e set for different types of batteries or conditions. The
following recommen dations should, however, only be seen as guidelines. Please consult the
batter y manufacturer for further i nstructio ns.

Settings are made by pres sing the “MODE-button “ and stepping for ward one press at a ti me

until the required mode i s reached, the but ton is then releas ed. After about 2 seconds the

charger activates the s elected mode. Th e selected mode is saved in a memory in the charg er
and remai ns there even if the charger is disconnected from battery and mains.

NORMAL

SUPPLY

RECOND

NORMAL - Normal set ting for wet batte ries, mainten ance free
and for most Gel batteries. Some Gel batteries prefer a slightly
lower cha rging voltage. Please consult the batter y manufacturer
when in doubt.

SUPPLY - The charger operates at a constant voltage. This is
the maintenance mode fo r applications w here maximum capacity

from the battery is important, li ke oor sweeper s and golf carts.

Note that t he Spark protection function is suppresse d in this
mode.

RECOND - This mode is used to recover deep discharged

ooded batteries where you could expect a stratied acid

(high aci d weight in the bottom, low on top). Check w ith battery
manufac turer when in doubt .
Use this mode with care, b ecause the high vo ltage will cause
some wate r loss. 16V is normally no proble m for electronics in
12V system. Consult your supplier when in doubt . Life of light
bulbs will be reduced at higher voltage. Try to disconnect light
from the battery dur ing this phase. Maximum effect and minimum
risk for e lectronic s is achieved by charg ing a disconne cted
batter y.

CHARGING PHASES

MULTI XS 1500 0 charges and analyses in eight f ully automatic ste ps and has three different
operating modes, see Battery Types and S ettings.

The battery charger has an 8-step f ully automatic charging cycle:

Desulphation

Desulphation with pul ses recovers sulphated batt eries. Indic ates with lamp 1.

Soft start (Lam p 1)

Start mode for the cha rging cycle. Th e charging current is limited. The start phase c ontinues
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 wit hin the
time limit, the charger switches to fau lt mode (lamp 0) and discontinues the charging. If so, the
batter y is faulty or its c apacity is too large.

Bulk (La mp 2)

Main charge when 80% of charging takes place. The charger delivers ma ximum current until the
terminal voltage has risen to the set level. Bulk has a maximum time, at which p oint the charger
automatically switc hes to Absorption.

Absor ption (Lamp 3)

Complete charge up to vir tually 100%. Th e terminal volt age is maintained at the set level.
During t his phase the current tapers suc cessively. Once the current has tapered to the s et limit,
this phas e switches to being timed. If the tot al time for Absorption exceeds the time limit the
charger automatically switches to m aintenance.

Analysis (Lamp 3)

Testing self-discharge. If self-discharge is too high, charging is discontinued and fault mode i s
indicated.

Maint enance charging - Float (Lamp 4)

Chargin g at constant voltage.

Maint enance charging - Pulse (La mp 4)

Chargin g varies between 95% and 100% st ate of charge. The battery receives a pulse when the
voltage drops and keeps the battery in p erfect condition when it is not in use. The cha rger can
be connected for months at a time. The charger continuously measures the terminal voltage
to determ ine whether a charging pulse sh ould be initiated. If the batter y is loaded and/or the
batter y’s terminal voltage drops the c harger starts a charging puls e until the terminal voltage
reaches the set level. The c harging pulse is then discontinued and the cycl e is repeated

innite ly. If the terminal voltage drops below a lower limi t, the charger automatical ly goes back

to the beginning of the cha rging curve.

Recond (Lamp 5)

This mode is used to recover deeply discharged ooded batteries. Recondition of deep

discharged batteries. The voltag e increases with r educed current for a limited tim e period. The

higher vo ltage starts some gassin g and mixing of the acid, which is benecial for both battery

capaci ty and expected life. Note that t he battery could emit explosi ve gas during Recond.
Recond is performe d between Analysis and Maintenance.

Fault mo de

The char ger goes to fault mode if the time f or gradual star t has been exceeded or if the batte ry’s
self-discharge is too high.

TEMPERATURE COMPENSATION

MULTI XS 1500 0 has a sensor cab le placed together with the battery cab les. The units w ill
automatically adjust the charging vo ltage if the tem perature deviates from +25°C. A high
temperature lowers the voltage and fr eezing conditions is handle d by higher voltage.
The temperature is best m easured on or ver y close to the bat tery. Therefore always place the
sensor as c lose to the battery as possible when charging. The sensor cable could be prolonged
or cut to length with the sam e functional ity. A short-circuited or disconnected sensor is indic ated
by lamp A. T he charging voltage is then adjusted to the +25°C co ndition.
