SAFETY

The charger is designed for lead-acid batteries from 14225Ah. 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. Dont 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 chargers memory and remains even when the charger is switched off.
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 5C. It is also recommended for many AGM batteries. This setting is not recommended for maintenance charging when the temperature at times exceeds +5C. 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 0.54h) 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 vehicles 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.
Start charging 1. Connect the power cord to the power outlet. 2. Set the proper charging mode for the battery by pushing the Mode button until the correct setting is lit. Choosing settings for your battery is described under BATTERY TYPES AND SETTINGS. 3. The lamp for Deep Discharged battery (1) will indicate if the battery voltage is low. If lamp 1 blinks, this indicates that the battery is lightly sulphated. Read more under CHARGING PHASES 4. Normal charging is indicated by the following lamps: Deep Discharged (1), Bulk Charge (2), Absorption Charge (3) or Maintenance Charging (4). When the maintenance lamp is lit, the battery is fully charged. The charge will restart if the voltage drops. The charger can be connected for months. SUPPLY or RECOND are indicated when the lamps for these settings are lit (5 or 6). 5. 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. 6. If nothing happens. If the setting lamp is lit but no other light comes on, the connection to the battery or to the chassis may be poor, or the battery may be faulty. Start by improving the contact between the battery and the charger. 7. Charging can be interrupted at any time by disconnecting the power cord from the wall socket or by putting the charger in "Standby" mode (lamp A). Always disconnect the power cord from the socket before removing the battery cables. When you interrupt charging of a battery mounted in a vehicle, always disconnect the battery cable from the chassis before removing the other battery cable.

CHARGING PHASES

Mode chosen: NORMAL or SNOWFLAKE
MULTI XS 7000 is a multi stage fully automatic charger. Lamp B for chosen setting NORMAL and lamp C for chosen setting SNOWFLAKE. Desulphation (Lamp 1, blinking) Desulphation with pulsing for sulphated batteries. Indicated by blinking lamp 1. Start (Lamp 1) Starting phase for charging. The starting phase continues until the batterys terminal voltage has risen over a preset level. At this point, charging goes into the bulk phase. If the terminal voltage has not reached the preset level within 8 hours, charging is suspended. The error mode is indicated. This indicates a battery which is faulty or has too large capacity. If a large battery is charged that has been severely discharged, it may be necessary to restart the charger after 8 hours. Start is indicated by lamp 1. Bulk (Lamp 2) Primary charging where approximately 80% of the charging happens. The charger delivers maximum voltage until the terminal voltage has risen to the preset level. After a number of hours, the charger goes on to the next phase, even if maximum voltage is not reached. Bulk is indicated by lamp 2. Absorption (Lamp 3) Final charging, voltage is kept at the preset level. During this phase, the voltage is gradually reduced. If the maximum length of time for Absorption is exceeded, the charger automatically continues with Analysis. Absorption is indicated by lamp 3.
Analysis (Lamp 3) Charging is suspended for a short period and the battery voltage measured. If it falls too quickly, the battery is probably faulty. Charging is suspended and an error is indicated (lamp 0). Maintenance charging - float (Lamp 4) During the first 10 days of maintenance charging the battery is maintained with constant voltage, 13.6V. Float-maintenance is indicated by lamp 4. Maintenance charging - pulse (Lamp 4) The state of charge varies between 95% and 100%. The battery receives a pulse when the voltage sinks, keeping the battery in good shape when it is not being used. The charger can be connected for months at a time. If the battery is charged and/or the batterys terminal voltage drops, the charger starts a charge pulse until the voltage has reached the preset level, 14.4V or 14.7V. The charge pulse is then interrupted and the cycle is repeated as long as the charger is in pulse maintenance phase. If the terminal voltage drops even lower, the charger automatically reverts to the beginning of the charging curve. Pulse maintenance phase is indicated by lamp 4. If possible, check the water level in the battery.

Chosen mode: SUPPLY

MULTI XS 7000 has a Supply mode setting which has a constant voltage of 13.6V and current up to 7A. This mode can also be used for maintenance charging of an already fully charged battery, called Float maintenance. This type of charging keeps the battery at 100% charge. The constant small overcharge can also increase water loss. A battery does not have to be connected for the charger to deliver voltage. This means that the spark protection is not active in this mode. It is not appropriate to charge a completely discharged battery in Supply mode, since this will not result in a completely charged battery. In this mode, MULTI XS 7000 can also be used as a power generation unit for operating equipment that requires 13.6V and a maximum of 7A. If the selected current exceeds 7A, the output voltage will drop as the load increases. The charger has electronic overload protection in this mode, which is activated if the charge is so great that the output voltage from the charger falls below around 9V and the current s around 7A. In the event of an overload, the charger goes into error mode (lamp 0). Supply mode is indicated with lamp D and lamp 5.

Chosen mode: RECOND

MULTI XS 7000 has a Recond mode which is used to recondition a battery that has been severely discharged. The battery is first charged using the mode NORMAL. When the analysis phase is complete, the charger begins reconditioning the battery by providing a constant current of 1.5A and a maximum voltage of 15.7V. After 0.54 hours, the battery is completely reconditioned and the charger goes into pulse maintenance. The battery is ready to be used, or store it with pulse maintenance active until you are ready to use the battery. Recond is indicated by lamp E and lamp 6. Note that the recond phase begins with normal charging and that the charger therefore will indicate the charging phases according to the descriptions above first. Lamp 6 is first lit when the reconditioning begins.

TEMPERATURE PROTECTION

MULTI XS 7000 is protected from being overheated. The power will be reduced if the ambient temperature is raised.

MAINTENANCE

The charger is maintenance free. Note that disassembly of the charger is not permitted and will void the warranty. If the power cord is damaged, the charger must be left to the reseller for maintenance. The case can be cleaned with a soft damp cloth and mild cleanser. The charger should be disconnected from the power supply while cleaning.

EQUIPMENT

MULTI XS 7000 is delivered with a set of battery cables with battery pole clamps and a set of battery cables with eyelet terminals.
