The Battery Equalize screen enables the operator to adjust the battery equalize time. It is also used to choose between auto and manual battery equalize recharging modes.

When the input utility power is interrupted, the battery supplies DC power to the inverter so there is no interruption of power to the critical load. When the AC input power is restored, the battery equal- ize recharging circuit can be activated automatically or manually to increase the rectifier/charger out- put voltage to recharge the battery. The battery equalize circuit may be manually activated at any time during normal float (constant) voltage operation. The equalizing time can be adjusted from

0 to 72 hours.

! CAUTION

Do not use the Battery Equalize mode if you have valve-regulated, lead-acid batteries. Refer to your battery manufacturer’s manual, available on the manufacturer’s Web site.

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. This period is set by use of the Up/Down pads and Select pad.

When the battery is at full voltage (not being recharged), this selection reads EQUALIZE TIME PERIOD (hrs). When the battery is recharging, this selection reads EQUALIZE TIME REMAINING (hrs). After the equalize recharge time has expired, the indication returns to the preset equalize time.

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.

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.

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.
