Battery Charger MXT 14000 AE For lead-acid batteries User Manual and Guide to professional charging of starter and deep cycle batteries. Model 1015... - Page 2 INTRODUCTION Congratulations on purchasing your new CTEK professional switch mode battery charger. This charger is part of a range of professional battery chargers from CTEK SWEDEN AB. It represents the latest technology in battery charging with charging and analysis in seven steps with temperature compensation. Read this User Manual and follow the instruc- tions carefully before using your new charger. SAFETY • The charger is designed for lead-acid batteries. 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.

Page 3: Charging Phases
3. Normal charging will be indicated by the following lights: start (1), bulk charging (2), absorption charging (3) or mainte- nance 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 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 is damaged and is indicated by lamp (0). 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. 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 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 charger is programmed according to “PROGRAM DESCRIPTION” with fixed settings and 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 setting for wet batteries, maintenance free and for most Gel batteries. Some Gel NORMAL 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 SUPPLY where maximum capacity from the battery is important, like floor sweepers and golf carts. Note that the Spark protection function is suppressed in this mode. RECOND - This mode is used to recover deep discharged flooded batteries where you could expect a stratified acid (high acid weight in the bottom, low on top). Check with battery manufacturer when in doubt. RECOND Use this mode with care, because the high voltage will cause some water loss. 32V is normally no problem for electronics in 24V system. Consult your supplier when in doubt. Life of light bulbs will be ... - Page 4 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 infinitely. If the terminal voltage drops below a lower limit, the charger automatically goes back to the beginning of the charging curve. Recond (Lamp 5) This mode is used to recover deeply discharged flooded batteries. Recondition of deep discharged batteries. The voltage increases with reduced current for a limited time period. The higher voltage starts some gassing and mixing of the acid, which is beneficial for both battery capacity and expected life. Note that the battery could emit explosive gas during Recond. Recond is performed between Analysis and Maintenance. INDICATORS SUPPLY RECOND MODE NORMAL SUPPLY RECOND...

8-step, fully automatic Battery types All types of 24V lead-acid batteries (WET, MF, AGM and GEL) Battery capacity 28–300Ah, up to 500Ah maintenance Degree of protection IP44 (Outdoor use)*** Weight 3.5 kg Battery cable 6m with Anderson Powerpole connector Extension cable 60cm with battery clips, 50cm with 12mm DC plug. (DIN EN ISO 4165), 50cm with 19mm cig plug connector**** Fuse *) Back current drain is the current that the charger drains from the battery if the AC cord is disconnected. **) The quality of the charging voltage and charging current are very important. High current ripple heats the battery and ages the positive electrode. High voltage ripple can damage other equipment connected to batteries. The battery chargers from CTEK produce very high quality voltage and current with low ripple. ***) IP44 cannot be guaranteed if the charger is not positioned horizontally with the long side or topside turned up. ****) When using the 19mm cig plug connector the mating part must be approved for 14A or more. MAINTENANCE The charger is maintenance-free. The charger must not be opened; doing so will invalidate the warranty. If the power cable is damaged it must be replaced by CTEK or its authorized representative. The charger casing can be cleaned using a damp cloth and mild cleaning agent. Remove the plug from the power socket before cleaning.
