OPERATING THE AT30

2.2.3. Selecting the Float or Equalize mode
The AT30 has 2 output voltage settings, Float and Equalize. Use the Float
mode for all normal battery charging and to operate your dc system. Use
the Equalize mode if it is necessary to balance the level of charge among
the cells of the battery. Consult your battery data sheets for information on
equalize charging your battery.
•
Press the CHRG MODE key to change to the equalize mode.
If the equalize method is set to manual timer or auto-equalize timer, the
charger will revert to the float mode at the end of the selected equalize
time.
•
You can press the CHRG MODE key again at any time to change back to the
float mode.
2.2.4. Choosing the Equalize method
Press the EQLZ MTHD
key to choose the desired equalize method. The
indicator next to the desired equalize method will light. Three equalize
methods are available in the AT30:
•
Manual Timer
•
Manual Equalize
•
Auto-Equalize Timer
These equalize methods are described below.
Manual Timer Method
Choose the manual timer method if you perform regularly scheduled
equalize charging, or if you base your equalize charging on regular
readings of the specific gravity of each cell of your battery (for lead-acid
batteries). When your battery requires equalize charging, adjust the
manual timer to 1-2 hours for each 100 AH of battery capacity (see
Section 2.3.3 to learn how to adjust the equalize time). The battery
manufacturer can help you determine the best equalizing schedule for
your battery.
After you select the manual timer method, press the CHRG MODE key to put
the charger into the equalize mode. The EQLZ indicator will light. When
the equalize timer is finished, the charger reverts automatically to the float
mode, and the
FLOAT indicator lights.
At any time during the equalize charge, you can switch the charger back
to float mode by pressing the
CHRG MODE key. The FLOAT indicator will
light.
If there is an ac power failure during the equalize charge, the AT30
remembers the remaining equalize time. When ac power is restored, it
resumes the equalize charge where it left off.
