OPERATING THE AT30

Manual Equalize Method

Choose the manual equalize method when you want to equalize charge the

Never leave the AT30 unattended in the equalize mode
with the manual equalize method selected. A sustained
overcharge may cause permanent damage to the battery.

Auto-Equalize Timer Method

Choose the auto-equalize timer method if you have a flooded (non-sealed)
battery, that is subject to infrequent discharges, or when the battery will be
discharged by at least half of its rated capacity during an ac power failure.
When ac power is restored to the AT30, it turns on in the equalize mode
automatically, and the EQLZ indicator lights. At the end of the equalize
charging time that you select, the AT30 reverts automatically to the float
mode, and the FLOAT indicator lights. At any time during the equalize
charge, you can switch the AT30 back to float mode by pressing the
key. The FLOAT indicator will light.
MODE
Consult your battery manufacturer's instructions before
using the auto-equalize timer method with sealed (valve-
regulated) lead-acid batteries.
Whenever the ac supply fails for 12 seconds or longer, the auto-equalize
timer is enabled. For shorter periods, the timer behaves as listed below:
