OPERATION
5-3 March 7, 2008
Battery Disconnect Shutdown
If the battery is disconnected from the charger during a
charge cycle, the charger will be shutdown. All LEDs
will be off.
Low Current Shutdown
If the charger output current falls below a predeter-
mined level, a low current shutdown will occur. All 4
LEDs will flash, then the “Equalize” LED will flash.
AC POWER FAIL
During an AC power failure, the AC500 Control stores
key information about the charge cycle. The informa-
tion is retained by powering some of the control’s key
components with a battery derived power supply. This
causes the control to resume the charge where it left off
when the AC power is returned, unaffecting timers and
equalize requests.
