observe any defective segments or indicators. When the self-diagnostic is complete, the charge starts if
no delay is set, and the yellow ‘Charging’ indicator lights. The display shows the charging amps and
battery volts per cell along with a message to indicate the charger is in phase 1 of the charge cycle. If
auto start is disabled, the display shows ‘CHARGER OFF’. Press STOP to manually start the charge.
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.
