When the battery is 80% charged, the charger starts phase 2 of the charge cycle.
When a charge is finished, the charger automatically turns off. The yellow ‘Charging’ indicator goes out.
If cool down is enabled, the display shows the cool down time remaining. If cool down is disabled or the time
has elapsed, the display shows ‘
0A x.xxVC ’ along with a message indicating the battery is ready and the
green ‘Complete’ indicator lights.
2.1.4.1 Disconnecting the Battery
Warning: Risk of explosion. Do not disconnect the battery while the charger is running. Hydrogen gas produced
by the battery during charging can be ignited by arcing that occurs when the battery cable is disconnected.
If the battery must be disconnected before the end of the charge cycle, the charger should be turned off
first. Press STOP, and verify the yellow ‘Charging’ indicator goes out. The LCD display shows ‘
CHARGER
OFF’. The battery may then be safely disconnected. If the green ‘Complete’ indicator is lit, the battery may be
disconnected at any time.
2.1.5 Equalize Charge
Over time batteries can develop inequalities in cell charge. This can lower the effective capacity of the
battery and shorten life. An equalizing charge re-balances the charge in the battery cells. Perform an equalize
charge if any of the following conditions exist:
1. On flooded batteries the specific gravity of any cell at the end of charge is 20 points less than the average of all
the cells.
2. The on-charge voltage of any cell at the end of charge is 20 millivolts less than the average of all the cells.
3. The battery has been stored for 30 days.
The 046-0371 control can perform an equalize automatically if auto equalize is enabled. Normal
equalize consists of an additional 3 hour charge time at the end of a normal charge cycle. The 046-0371
control can also perform an equalize charge when requested manually. First connect the battery and allow the
charge to start normally. Then press =. The display shows ‘
=’ on the left side and the charge time is extended
by 3 hours to allow the cells to equalize their charge.
The auto-equalize or manual equalize cycle can be cleared by pressing = while in the normal charge
cycle. The ‘
=’ indication on the display turns off. The next auto equalize charge occurs after the set number of
charge cycles if auto equalize is enabled. If the set number of charge cycles have been completed, the
charger attempts to equalize after the next charge cycle and continues to attempt to equalize until an equalize
cycle has completed.
The default setting for automatic equalize is every 7 cycles. To change the number of charge cycles for
automatic equalize, refer to the programming section.
2.1.6 Delayed Start
The delayed-start feature allows the operator to delay starting the charge cycle. This might be desired to
reduce peak energy surcharges if the charger were ready to start during a peak energy period. The delay time
could be set to keep the charger from starting until after the peak period ends.
To view or change the delayed start setting, refer to the programming section.
2.1.7 Auto- Refresh Charge
The 046-0371 control can provide an auto-refresh charge as long as the battery remains connected
to the charger if enabled. If AC power is lost during the wait period, the control resumes from where it left off
after power is restored. During the auto-refresh charge, the amp-hours and charge time are added to the
original charge. The refresh charge consists of 30 minutes at the equalize current. To change the auto-
refresh settings, refer to the programming section.
