NOTE:
When the battery is fully charged, the charger and timer will not automatically
turn off. It is important to monitor the charge level. Not doing so may cause damage to
the battery or may cause other personal property damage or personal injury.
Charger Settings for Automatic Charging:
Set the Function Switch to the desired charge rate setting.
1.
Press the Charge Rate button
2.
to select the desired charge rate.
Press the Auto Start button
3.
.
Within a few seconds the charger will start charging in Automatic Mode (see
4.
Automatic Charging Mode below).
NOTE:
When in automatic mode, this charger is equipped with an auto-start feature.
Current will not be supplied to the battery clips until a battery is properly connected.
Meaning, the clips will not spark if touched together. However, when in manual mode,
the auto-start feature is not applicable and the clips will spark if they contact each other
or the same piece of metal.
Battery Connection Indicator
If the charger does not detect a properly connected battery, the CONNECTED LED
will not light. Charging will not begin if the CONNECTED LED
is not on.
Automatic Charging Mode
When an Automatic Charge is performed, the charger switches to the Maintain Mode
(see Maintain Mode below) automatically after the battery is charged. For a battery with
a starting voltage under 1 volt, use the Manual Mode first to pre-charge the battery for
five minutes, to get additional voltage into the battery for the charger to analyze.
Manual Charging
If you do not press the Auto Start button
, you will be charging in manual mode.
When a Manual Charge is performed, the charger will continue to charge and will not shut
off. You must keep a visual check to determine when the battery is charged. Be sure to
monitor the charging process and stop it when the battery is charged. Not doing so may
cause damage to your battery or result in other property damage or personal injury.
Aborted Charge
If charging cannot be completed normally, charging will abort. When charging aborts,
the charger’s output is shut off and the digital display will show a failure code (see the
TROUBLESHOOTING section for a description of the failure codes). In that state, the
charger ignores all buttons. To reset after an aborted charge, turn the Function Control
switch to the OFF (O) position. Then place the Function Control switch back in the
previous position and reset all of the controls to the desired settings.
Desulfation Mode
Desulfation could take up to 10 hours. If desulfation fails, charging will abort, and the
digital display will show a failure code of F02 (Bad Battery).
Completion of Charge
Charge completion is indicated by the CHARGED LED
. When lit, the charger has
switched to the Maintain Mode of operation.
Maintain Mode (Float-Mode Monitoring)
When the CHARGED LED
is lit, the charger has started Maintain Mode. In this mode,
the charger keeps the battery fully charged by delivering a small current when necessary.
NOTE
: If the charger has to provide its maximum maintain current for a continuous 12
hour period, it will go into Abort Mode (see Aborted Charge section). This is usually
caused by a drain on the battery, or the battery could be bad. Make sure there are
no loads on the battery. If there are, remove them. If there are none, have the battery
checked or replaced.
Maintaining a Battery (2 Amp
Charge Rate)
The SWI-1555A is a battery charger with a maintenance setting that maintains 12 volt
batteries keeping them at full charge. On this setting, it can charge small batteries and
maintain both small and large batteries. If you are maintaining a fully charged large
battery, you will be properly utilizing the maintenance setting. However, if you were to
use the maintenance setting to charge a large battery, such as a marine deep cycle
