INTRODUCTION
Congratulations on your purchase of your new professional MULTI XS 7000 Switch Mode
Charger with Pulse Maintenance, Float, Analysis and Recond. MULTI XS 7000 is a member of
a family of professional chargers from CTEK SWEDEN AB. It represents the state-of-the-art
technology for battery charging. A MULTI XS 7000 will prolong the lifetime of your battery. Read
this user manual and follow the instructions carefully before using the charger.
SAFETY
The charger is designed for lead-acid batteries from 14–225Ah. Do not use the charger for
•
any other purpose
Use safety glasses and turn your head away when connecting or disconnecting a battery.
•
Battery acid is corrosive. Rinse immediately with water if acid comes into contact with skin or
•
eyes. Seek medical advice.
Make sure that the cable is not pinched or in contact with warm surfaces or sharp edges.
•
While charging, a battery can emit explosive gases, so it is important to avoid sparks in the
•
immediate area.
Always provide for proper ventilation during charging.
•
Avoid covering the charger.
•
Make sure that the electrical cable does not come into contact with water.
•
Never charge a frozen battery.
•
Never charge a damaged battery.
•
Do not place the charger on the battery while charging.
•
The electrical connection must fulfil the national heavy current requirements.
•
Check 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 flat 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.
BATTERY TYPES AND SETTINGS
MULTI XS 7000 can easily be configured to charge many different types of 12V lead-acid batteries; wet batteries, MF, AGM and for most GEL-batteries.
The following recommendations should, however, only be seen as guidelines. When in doubt,
always consult the battery manufacturer for further instructions.
Settings are made by pressing the “MODE-button” and stepping forward by pressing the button
one step at a time, releasing the button when the required mode is reached. After approx. 2
seconds, the charger activates the chosen mode. The selected mode is saved in the charger’s
memory and remains even when the charger is switched off.
MODE
”NORMAL” (14.4V)
Normal setting for wet batteries, MF and for most Gel batteries.
Mode ”SNOWFLAKE” (14.7V)
This setting is recommended for batteries at temperatures below 5°C. It is also recommended
for many AGM batteries. This setting is not recommended for maintenance charging when the
temperature at times exceeds +5°C. In this case, the NORMAL mode is recommended.
Mode ”SUPPLY” (13.6V)
In this mode, the charger provides a constant voltage of 13.6V. This is the best maintenance
mode for batteries where maximum capacity is important, for instance for cleaning machinery
and golf carts. It is not appropriate to charge a completely discharged battery in Supply mode,
since this will not result in a completely charged battery. The MULTI XS 7000 can also be used
as a power supply without a battery attached in this setting. No counter voltage is required to
start the charger in this mode. Note that the charger is not spark free in this mode.
Mode ”RECOND” (15.7V, 1.5A 0.5–4h)
This mode is used to recondition very discharged batteries where you could expect a stratified
acid (high acid weight in the bottom, low on top). Use this mode with care because it can cause
some water loss. 15.7V is normally not a problem for electronics, but consult the manufacturer
when in doubt. Life of light bulbs can be reduced by higher voltages. Try to avoid using 12V
lamps connected to the battery during this phase. Maximum effect and minimum risk for
electronics is achieved by disconnecting the battery before charging.
CHARGING
Charging batteries mounted in a vehicle:
1. The power cord should be disconnected before connecting or disconnecting the battery
leads.
2. Identify the pole that is grounded (attached to the chassis). Ground is normally connected to
the negative terminal.
3. Charging a negatively grounded battery. Connect the red cable to the positive pole of the
battery and the black cable to the vehicle’s chassis. Be careful not to connect the black cable in
the vicinity of a fuel pipe or the battery.
4. Charging a positively grounded battery. Connect the black cable to the negative pole of the
battery and the red cable to the vehicle's chassis. Be careful not to connect the red cable in the
vicinity of a fuel pipe or the battery.
Charging of a battery not connected to a vehicle:
1. The power cord should be disconnected before connecting or disconnecting the battery
leads.
2. Connect the red cable to the positive pole of the battery and the black cable to the negative
pole.
Connecting the provided cables with eyelet terminals:
Make sure that the cable is not pinched or in contact with warm surfaces or sharp edges. When
the cable is mounted on the battery, it should not be connected to the charger. Connect the
eyelet terminals to the battery's poles - the red cable to the positive pole and the black cable to
the negative pole. After this, the quick connector can be connected.
Reverse Polarity Protection
If the battery cables are connected incorrectly, the reverse polarity protection will make sure
that neither the charger nor the battery are damaged. In this case, the red warning lamp (0) will
be lit.
