Once charging is complete, the charger will automatically go into
Maintenance mode (also known as float mode monitoring). In this mode,
the charger keeps the battery fully charged by delivering a small amount
of current, when necessary, to keep the battery at peak charge. This
process will keep for around 1 hour, after which the digital display will
show "FUL", and the DC clamps will automatically go out of power.
REVERSE POLARITY PROTECTION
If the cables are incorrectly connected to the battery, the Reverse Polarity
indicator will illuminate. Note: the charger will not begin charging if the
Reverse Polarity indicator is lit.
BATTERY RECONDITIONING MODE
If a battery is left discharged for an extended period of time, it can
become sulphated, unable to accept a charge. The reconditioning Mode
may help reverse the effects of sulphation and restore a battery's ability
to accept a charge. If the charger detects a sulphated battery, it will
automatically activate Battery Reconditioning mode, indicated by a
blinking yellow LED. The digital display will show ."-" in turns. If
desulphation is successful, normal recharging will resume. If the first
attempt at desulphation is unsuccessful, the battery charger will make up
to four more attempts. If the process fails, fault code "F01" will be
displayed indicating the battery will not accept a charge and should be
replaced.
ABORTED CHARGES
If charging can't be completed normally, charging will be aborted. The
digital display may show a fault code. To reset the charger after an
aborted charge, disconnect the battery or unplug the charger.
BATTERY DIAGNOSTICS
The charger continuously monitors battery condition and may report
certain charging failures as fault codes. Refer to the section called
"FAULT CODES" for a complete list.
COOLING FAN OPERATION
The charger is designed to control its high speed cooling fan for efficient
operation. Consequently, it is normal for the fan to start and stop during
charging.
OVERHEAT PROTECTION
The charger is designed to shut itself off if overheating is detected. Once
the charger cools down, it will resume charging automatically.
