10. CONTROL PANEL

ON/OFF SWITCH
Use this switch to select between the
Charge/Maintain rate, Boost rate and the
Engine Start mode.
OFF – When the switch is in this position
(middle), the charger is turned off.
BOOST or
When the switch is in this position, the
Rate Selection button can be set to either
the 6<>2A Charge/Maintain or the
40A Boost setting.
ENGINE START – When the switch
is in this position, the Engine Start LED
will activate and will be solid when it is
connected to a battery.
DIGITAL DISPLAY
The Digital Display gives a digital indication
of voltage, % of charge or time. The
display will show the battery VOLTAGE
when the charger is not charging a battery.
When it goes into charging mode, the
display will automatically change to ON (to
show charging has started) and either 6 or
12 (the voltage of the battery, determined
by the charger).
NOTE: During charging, the display will
go into sleep mode and will not show the
percentage of charge or voltage of the
battery. To turn the display back on, press
the Display button.
DISPLAY BUTTON
Use this button to set the function of the
digital display to one of the following:
(Battery %) – The digital display
shows an estimated charge percentage
of the battery connected to the charger's
battery clamps.
Alternator % (12V only) – The
digital display shows an estimated output
percentage of the vehicle's charging
system connected to the charger's battery
clamps, compared to a properly functioning
system. The alternator percent range is
from 0% to 100%. Readings below 0%
(13.2 volts) will read LO and readings
above 100% (14.6 volts) will read HI . If you
get a HI or LO reading, have the electrical
system checked by a qualified technician.
(Voltage) – The Digital Display shows
the voltage at the charger battery clamps,
in DC volts.
CHARGE/MAINTAIN –
RATE SELECTION BUTTON
Use this button to select one of the following:
6<>2A CHARGE/MAINTAIN – For
charging small and large batteries. Not
recommended for industrial applications.
40A BOOST – For quickly adding
energy to a severely discharged or large
capacity battery prior to Engine Start.
The unit will automatically switch to
6A<>2A Charge/Maintain after the 40A
Boost operation has completed.
200A ENGINE START – Provides
200 amps for cranking an engine with
a weak or run-down battery. Always
use in combination with a battery.LED
INDICATORS
CLAMPS REVERSED (red) LED
flashing: The connections are reversed.
(yellow/orange) LED lit:
The charger is properly connected
and the battery is receiving power.
CHARGED/MAINTAINING (green)
LED lit: The battery is fully charged
and the charger is in maintain mode.
NOTE: See Operating Instructions for a
complete description of the charger modes.
BATTERY TYPE BUTTON
Use this button to select the type of battery.
– Used in cars, trucks and
motorcycles, these batteries have
vent caps and are often marked "low
maintenance" or "maintenance-free".
This type of battery is designed to deliver
quick bursts of energy (such as starting
engines) and has a greater plate count.
The plates are thinner and have somewhat
different material composition. Standard
batteries should not be used for deep-cycle
applications.
– The Absorbed Glass Mat
construction allows the electrolyte to
be suspended in close proximity with
the plate's active material. In theory,
this enhances both the discharge and
recharge efficiency. The AGM batteries
are a variant of Sealed VRLA (valve
regulated lead-acid) batteries. Popular
uses include high-performance engine
starting, power sports, deep-cycle, solar
and storage batteries.
