manual abstract
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) Charging varies between 95% and 100% state of charge. 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) (only on MULTI XS 25000 and MULTI XT 14000) 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 Lamp Description 0 Fault mode, the charging is discontinued. For fault causes, see below. 1 Start mode 2 Bulk charging 3 Absorption charging 4 Maintenance charging 5 Supply (Only on MULTI XS 25000 and MULTI XT 14000) 6 Recond reconditioning of completely discharged batteries. (Only on MULTI XS 25000 and MULTI XT 14000) A Charging without temperature compensation. B Mains voltage connected C Normal (Only on MULTI XS 25000 and MULTI XT 14000) D Supply (Only on MULTI XS 25000 and MULTI XT 14000) E Recond (Only on MULTI XS 25000 and MULTI XT 14000) Fault mode The charger goes to fault mode if the time for gradual start has been exceeded or if the battery’s self-discharge is too high. TEMPERATURE COMPENSATION MULTI XS 25000, XS 25000, MULTI XT 14000 and XT 14000 have a sensor cable placed together with the battery cables. The units will automatically adjust the charging voltage if the temperature deviates from +25 C. A high temperature lowers the voltage and freezing conditions is handled by higher voltage. The temperature is best measured on or very close to the battery. Therefore always place the sensor as close to the battery as possible when charging. The sensor cable could be prolonged or cut to length with the same functionality. A short-circuited or disconnected sensor is indicated by lamp A. The charging voltage is then adjusted to the +25 C condition. SPECIFICATION MULTI XS 25000 XS 25000 MULTI XT 14000 XT 14000 Voltage AC 170-260 VAC, 50-60 Hz. Charging voltage 14.4 V 28.8 V Charging current 25 A max. 14 A max. Current, mains 2,9 A rms (at full charging current) Back Current Drain* <2Ah per month Current ripple** <4 % Ambient temperature - 20°C to + 50°C Output power is automatically reduced at higher temperatures. Cooling Fan Charger type Eight-step, fully automatic Battery types All types of 12 V lead-acid batteries (WET, MF, AGM and GEL). All types of 24 V lead-acid batteries (WET, MF, AGM and GEL). Battery capacity 40-500Ah 28-300Ah up to 500 Ah maintenance Protection class IP 44 (Outdoor use)*** Weight 1,4 kg *) 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 produces very high quality voltage and current with low ripple. ***) IP 44 cannot be guaranteed if the charger is not positioned horizontally with the long side or top side turned up.
