SW Series Inverter/Charger
Part No. 2031-5
Rev. C: February 2001
EQUALIZATION CHARGING, AUTOMATIC GENERATOR CONTROL SYSTEM
An automatic equalization charge process is available in the SW Series Inverter/Charger. To start the
equalization process, select EQ from the SET GENERATOR menu item, accessible by pressing the green
GEN MENU button on the Control Panel.
During the next automatic generator run period, the inverter can be set to complete an equalization charge
process. You must first select EQ from the SET GENERATOR menu item. The generator will start the
equalization process the next time the generator is automatically started and will automatically stop and
return the cursor to the AUTO position in the SET GENERATOR menu item once the equalization period
has been completed.
The SET EQUALIZE TIME menu item under the BATTERY CHARGING (10) menu heading sets the
amount of time that the battery voltage must exceed the BULK VOLTS DC setting before the equalization
process is considered to be completed. This timer is an accumulating type timer that does not reset if the
voltage drops momentarily below the bulk voltage setting. During the equalization process, the voltage will
be limited to the level of the SET EQUALIZATION VOLTS DC menu item.
During the equalization process, the BULK LED will flash slowly to indicate that the EQ position has been
selected from the SET GENERATOR menu item. When the process has finished, the FLOAT LED will be
on if the generator or utility power is still available.
