8
up to 5 seconds or until the engine
cranking stops. The digital display
shows a countdown of the remaining
crank time in seconds. It starts at 5 and
counts down to 0.
3.
Cool Down
- After cranking, the char-
ger enters a mandatory 3-minute (180
second) cool down state. During this
period, no settings can be changed.
The buttons are ignored. The digital
display indicates the remaining cool
down time in seconds. It starts at 180
and counts down to 0. The 75A START
LED blinks once every second.
During
the cool down period, no current is de-
livered to the battery. After 3 minutes,
the 75A START LED will stop blinking
and will light continuously, indicating that
another crank cycle can be started. The
digital display will change from display-
ing the countdown back to displaying
the battery voltage. The CHARGING
LED will then be lit.
ENGINE STARTING NOTES:
• If the battery is disconnected during
the cool down period, the charger will
reset.
USING YOUR BATTERY CHARGER
OVERVIEW
Using this battery charger is very simple.
First, connect the battery and AC power
following the precautions listed under
“OPERATING INSTRUCTIONS”. Then
select 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 lit.
AUTOMATIC SHUT OFF:
When the 2A,
12A
30A charge rate is selected, the
charger is set to perform an automatic
charge. When an automatic charge is
performed, the charger stops charging au-
tomatically 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. If
desulfation fails, charging will be aborted
and the CHECK (red) LED will blink.
C O M PL E T I O N O F C H A RG I N G:
Charge completion is indicated by
the CHARGED (green) LED; when
lit, the charger has stopped charging
and switched to the Maintain Mode of
operation.
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 amount
of current, when necessary. The voltage
is maintained at a level determined by the
BATTERY TYPE selected.
GENERAL CHARGING NOTES:
The charger is designed to control its
cooling fan for efficient operation. Con
-
sequently, it is normal for the fan to start
and stop when maintaining a fully charged
battery. The fan does not run in Tester
Mode.
