4.7.3 Equalization charging
Before you program the XP-COMPACT for Equalization-charge you must check with
your supplier that the batteries are suitable for this process.
Equalization is recommended for the lead-acid batteries in order to mix well the
electrolyte fluid and to clean the lead plates.
If the XP-COMPACT is operating with a lead-acid battery, which is suitable for
equalization, the slide switch „Equalize“ which is on the cable connection side, must
be placed in the ON position. In this setting, every 25 charge cycles an equalization is
carried out for 20 minutes (factory setting). During such a charge cycle the LED 14 is
lit and during equalizing it is blinking. Charge cycle with equalization can be started
independently from the actual program. For this purpose the slide switch must be slid
from “OFF” to the “ON” position. The LED 14 will light up. If the periodic equalization
is not required, slide switch must be slid back to the „OFF“ position after the
completion of the manual cycle.
The equalizing voltage can be changed. How to proceed is explained in chap. 5.3.
Batteries not designed for equalize should never been charged this way.
CAUTION: During the equalization process, the batteries produce a lot more
gas. DANGER OF AN EXPLOSION !! The battery room must be well ventilated.
Equalization mode should never be used when using Gel-Batteries.
4.7.4 Charging current
The maximum charging current for the battery can be adjusted with the Turning Knob
22 (CHARGER). The charging current of the battery should be set to approximately
10 – 20% of the battery capacity (at C10). This means that the charging current for a
battery with 200Ah should be set between 20 – 40A.
The charging current is displayed on POWER MONITOR (25) of the front panel
or on the Remote Control.
