Maintenance - DEFA 32A Gebrauchsanleitung

DEFA ShowroomCharger 32A is based on modern switch-mode technology and galvanized divisions. This charger represents the latest technology within
battery charging and will give the batteries optimum life. It is well suited to charge lead/acid, AGM and GEL batteries up to approx. 250Ah and can
maintenance charge the battery for an unlimited time. The charger can stand parallel charging up to 30A parallel consumption at the same time as it
charges the batteries.
See figure 1 on page 2. The figure shows the charge process in a graph with Voltage (V) and Current (I) over time (t)
The charge status is shown by the LED display. See figure 2 on page 2.
The charger checks if the battery is correctly connected.
The battery's charge level (V) and total capacity (Ah) is measured to determine the correct settings for charging.
Battery Voltage
>12.65V
12.55V–12.65V
12.45V–12.55V
12.35V–12.45V
4.5V–12.35V
The charger starts charging the battery with constant current up to 14.4V (at 25°C). The charge voltage is then held constant at 14.4V and the charging
current is reduced until it is below a defined level. The charge voltage then drops to 13.6V, before the long-term charging phase starts. During charging,
battery charge is shown by the number of LEDs illuminated. The blinking segment above these LEDs indicates active charging. Once full battery charge
is reached, all 5 LED segments remain illuminated. If the measured battery voltage is below 2.0V, the charger will enter Error Mode, and the warning
triangle above the battery indication will start to flash.
The charger analyses the battery again after the charging phase. Post analysis can detect batteries with a short circuit in individual cells. This cannot be
detected in the pre analysis. If the battery voltage drops below 12V within 2min, the charger will go into error mode and the red warning triangle will start
to flash. The charging sequence will be stopped.
After the battery is fully charged , the charger will deliver 13,6V with a maximum of 32A. This is indicated by all battery LEDs slowly pulsating.
Read the user guide carefully. If there are any uncertainties, please contact DEFA or a qualified person.
Connect red clamp to (+) and black clamp to (-). The charger is intended for use with lead/acid, AGM, EFB and GEL batteries. The battery manufacturer's
recommendations shall always be taken into consideration. NB: To make sure the correct charging voltages are applied to the battery the charging cables
must not we shortened or made longer.
Connect the AC mains cable to the charger. Push the power button once. See figure 2, page 2. The charger will start up and initialize the pre-analyze
process. To turn of the charger, push the power button again.
Make sure that the connector on both charger and cables (see figure 3, page 2) are free from moist and dirt before using the charger. All batteries should
be inspected monthly as a minimum to achieve the best possible safety. The charging process is in such way that the batteries remain fully charged
without further water consumption than normal evaporation.
If future needs require a software update of the charger, it can be done through the micro-USB port at the end of the charger.
See figure 4, page 2. Necessary information will be given along with the software.
