START LED will stop blinking and will
light continuously, indicating that an-
other crank cycle can be started. The
digitaI display will change from display-
ing the countdown back to displaying
the battery voltage. The CHARGING
LED will be lit again.
ENGINE STARTING NOTES:
• If the battery is disconnected during
the cool down period, the charger will
reset.
OVERVIEW
Using this battery charger is very simple.
First, connect the battery and AC power
following the precautions listed under
"OPERATING INSTRUCTIONS". Then
seIect the appropriate BATTERY TYPE
and CHARGE RATE for your battery. The
charger will then do everything automati-
cally. This section explains a few details.
CHARGING: If the charger does not
detect a properly connected battery, the
CHECK (red) LED will light continuously
until such a battery is detected. Charging
will not begin while the CHECK LED is on.
When charging begins, the CHARGING
LED will be Iit.
AUTOMATIC SHUT OFF: When the 2A,
15A or 40A charge rate is selected, the
charger is set to perform an automatic
charge. When an automatic charge is
performed, the charger stops charging
automatically after the battery is charged.
ABORTED CHARGE: If charging can't
be completed normally, charging will be
aborted. When charging is aborted, the
charger's output is shut off and the red
CHECK LED and digital display blink on
and off (at opposite times). In that state, the
charger ignores all buttons. To reset from
after an aborted charge, either disconnect
the battery or unplug the charger.
DESULFATION MODE: If a battery is
left discharged for an extended period, it
could become sulfated and not accept a
normal charge. If the charger detects a
sulfated battery, the charger will switch to
a special mode of operation designed for
such batteries. Activation of the special
desulfation mode is indicated by blinking
the CHARGING LED. If successful, nor-
mal charging will resume after the battery
is desulfated. The CHARGING LED will
then stop blinking and light continuously.
Desulfation could take up to 10 hours, tf
desulfation fails, charging wilI be aborted
and the CHECK (red) LED wilI blink.
COMPLETION OF CHARGING: Charge
completion is indicated by the CHARGED
(green) LED; when lit, the charger has
stopped charging and switched to the Main-
tain Mode of operation, ifthe type selected
was DEEP CYCLE or DieHard PIatinum.
For other battery types, the CHARGED
LED comes on 'when the battery is charged
enough for normal use.
MAINTAIN MODE: When the CHARGED
(green) LED is lit, the charger has started
Maintain Mode. This mode of operation is
also known as Float-Mode Monitoring. in
this mode, the charger keeps the battery
fully charged by delivering a small current,
when necessary. The voltage is maintained
at a level determined by the BATTERY
TYPE selected. NOTE: If the battery type
is REGULAR or AGM/Gel, the CHARGED
LED might be lit before Maintain Mode is
started.
GENERAL CHARGING NOTES: The
charger is designed to control its cooling
fan for efficient operation. Consequently, it
is normal for the fan to start and stop when
maintaining a fully charged battery. The fan
does not run in Tester Mode.
