AUTO START/DELAYED START
Auto Start enables the charger to start the charge cycle automatically after the battery is connected to the charger. A
programmable delay can be programmed so that Auto Start will begin after a set time period. This delay can be set
through the front panel display. Refer to Delayed Start in the USER parameter section. Auto start can be delayed
anywhere from 0 up to 25 hours, in one minute intervals.
AUTO/MANUAL EQUALIZE CYCLE
An Equalize Cycle adds a predetermined amount of time to extend the battery’s charge cycle. The ES3 charger is
equipped with an auto equalize function referred to as Equalize Count in USER parameters. This is a configurable
parameter; consult your service representative for more information. The factory default setting for the auto equalize
cycle is 3 hours of charge time for every fifth charge cycle. A charge cycle consists of at least one hour of continuous
charging of the battery by the charger. Every time the battery completes a charge cycle, the charge counter is
incremented. When the charge counter reaches the programmed Equalize Count value, an equalize cycle will occur
immediately after the battery completes its normal charge cycle. When an equalize charge cycle is pending, the
EQUALIZE LED will flash. The equalize button can be pressed at any time during the normal charge cycle to stop the
pending equalize cycle. Once the battery has completed a successful charge cycle, the CHARGE COMPLETE LED will
light and the charger will immediately go into the equalize charge cycle. The EQUALIZE LED will then light steadily.
Pressing the EQUALIZE button during the equalize charge cycle will have no effect on the charger. When Equalize on
Day is chosen in the Service Parameters, the Equalize Count is automatically disabled.
The charger can also equalize a battery manually. Pressing the EQUALIZE button at any time during the charge cycle
will activate the equalize function. Once pressed, the EQUALIZE LED will begin to flash indicating that an equalize cycle
will occur once the battery has completed a successful charge cycle. The EQUALIZE button can again be pressed at any
time during the normal charge cycle to stop the pending equalize cycle. The charge counter is reset every time the
charger completes at least one (1) hour in Equalize charge.
NOTE: Since Equalize charging extends the recharge time; it is best to do this when additional cooling time is available
(example: on a weekend). Consult your factory representative to determine Equalize intervals that meet your needs.
AC POWER FAIL
AC power may fail with a battery connected to the charger during a charge cycle. When AC power returns with the
battery connected, the charge cycle will resume the battery charging after a random delay. The charger will also detect
an AC fuse open when the charger is charging a battery. This will result in a stopping of the charge cycle and an AC fault
message displayed.
REFRESH CYCLE
If a battery remains connected to the charger for a predetermined amount of time after a charge cycle has been
completed, a refresh charge cycle will be given to the battery. The factory default setting for the Refresh Cycle is to
refresh for 20 minutes every 24 hours. This is a configurable parameter; consult your service representative for more
information.
COOL DOWN
When a battery completes a charge cycle without error, it ideally should cool down before being used. The Cool Down
period after a successful charge cycle is an idle period that allows a battery to cool off before use. Cool Down is a
configurable parameter that can be set through the front panel display, refer to Cool Down in section User Parameter.
The factory default setting for the Cool Down is 1 hour.
PARALLEL CHARGING (OPTIONAL)
In parallel charging, batteries must have an equal number of cells and must match the charger nameplate’s ratings. Amp-
Hour rating of charger must be equal to the Amp-Hour of both batteries combined. Theoretically, charging current is
