Selecting The Float Or Equalize Mode; Choosing The Equalize Method; Manual Timer Method - HindlePower AT30 SERIES Operating And Service Instructions

• When the AT30 starts initially, the meter alternates, displaying output
voltage and output current. The DC Volts and DC Amperes indicators
light alternately to indicate what is being displayed.

2.2.3. Selecting the Float or Equalize mode

The AT30 has two (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.

If the equalize method is set to Manual Timer or Auto-Equalize Timer, the
AT30 will revert to Float mode at the end of the selected equalize time.

2.2.4. Choosing the Equalize method

Press the

indicator next to the desired equalize method will light. Three (3)
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
the AT30 into the equalize mode. The
the equalize timer is finished, the AT30 reverts automatically to the float
mode, and the FLOAT indicator lights.
Any time during equalize charge, you can switch the AT30 back to float
mode by pressing the
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.
