G. Charger Information

G.1.1 Charging Cycle

The fully automatic battery charger can be adjusted so that most major battery types can be charged to the maximum,

As soon as the minimum AC voltage is available at the AC input (“AC IN” LED is lit),the Battery Charger is switched on automatically (“CHARGER” LED is lit). The battery is automatically charged to match the pre adjusted voltage levels and charge current. Thanks to the sophisticated and intelligent Floating Charge System, the batteries can be left in charge mode for unlimited time.

During the charging cycle, the AC loads are continually supplied with power from the incoming AC voltage source. (“AC OUT” LED is lit).

G.1.3 Input current repartition (Power sharing Fn06)

To manage the power available on the AC INPUT the unit is equipped with a system usually called “Power sharing” or INPUT power distribution. With this feature it is possible to limit the AC INPUT current assigned to the charger. The more current used by the AC load, the less power is given to the charger. Priority for the AC Loads. When power sharing is used the red 200% LED on the power monitor is lit to show that the battery charging is being limited.

G.1.4 Set the charging current (Fn07):

The maximum charging current or the battery can be adjusted by function Fn07. The charging current should be set to approximately 10-15% of the battery capacity (at C10). This means that the charging current for a battery with 300Ah should be set between 30-45A. The charging current is displayed on the “multi-display” or “CURRENT MONITOR” on the front panel

G.1.5 Battery Condition:

The built in microprocessor features a specially developed algorithm (formulae) which calculates the actual state of charge (SOC) of the battery and displays it on LED-8. The Equalize LED-7 is lit when the system is performing an equalization charge. The SOC displayed should be used as a guide only, for batteries which are not sealed, use a hydrometer to determine the exact SOC.

For safety reasons:

Make sure that the setting of the charger matches your battery type! The correct charging levels are critical for safe functioning and long life of the battery.
