From the Battery Equalizer Screen, you can choose one of the four options on the screen. The screens for these options are illustrated below.

AUTO MODE—When the battery recharge control logic is in the AUTO MODE, the UPS battery charger attempts the equalization process only if the EQUALIZE TIME PERIOD is greater than zero, the battery voltage has been at or below the Battery Discharging alarm limit for longer than 30 sec- onds, and the battery breaker (MBD) is closed.

MANUAL MODE. This mode enables the operator to manually initiate a battery equalize charge to raise the DC bus voltage to correct a non-uniformity in the individual cell voltages or specific gravity readings.

STOP EQUALIZE CHARGE—This selection lets the operator halt the equalizing charge to the bat- tery at any time, whether the circuit was activated automatically or manually.

EQUALIZE TIME PERIOD. This selection permits the Operator to adjust the battery equalize time in one hour increments from 0 to 72. The battery equalize time must be greater than zero for the bat- tery to begin recharging in both the AUTO and the MANUAL modes. Use Up/Down buttons to set battery equalize time and press SELECT.
