Status Codes are described in the following chart and on the back of charger.
AC POWER INDICATOR - When connected to an AC outlet, digital display shows circulating pattern to
indicate power is on. Disconnect charger after use.
INTERNAL SHORTED CELL BATTERY - Cannot be charged. Have battery checked by certified auto service center.
EXCESSIVE LOAD ON BATTERY WHILE CHARGING - Check load.
BAD BATTERY CONNECTION - Check battery connection.
BATTERY VOLTAGE TOO LOW TO ACCEPT CHARGE - Have battery checked by certified auto service center.
INTERNAL OPEN CELL - Have battery checked by certified auto service center.
SULFATED CONDITION - Battery needs to be reconditioned. See manual.
OVERTIME CONDITION - Battery will not accept a charge after 18 hours of continuous charging. Battery may have
internal damage. Have battery checked by certified auto center.
BATTERY CHARGE RATE IS SET TOO LOW - Set charger to higher charge rate. See manual.
OVERHEATED CONDITION - Disconnect charger and allow to cool for 30 min., check for ample ventilation.
ALTERNATOR OUTPUT IS OUT OF TYPICAL OPERATION RANGE
BATTERY RECONDITIONING - (The letters DES will display for the first 3 seconds.)
ALTERNATOR VOLTAGE CHECK
BATTERY FULLY CHARGED
CONTROL PANEL LED INDICATORS:
WET — lights when battery type selector is on WET battery type
GEL — lights when battery type selector is on GEL battery type
AGM — lights when battery type selector is on AGM battery type.
Float Charge — lights when automatic charge monitoring is active. This feature
allows a battery to maintain its charge over long periods of non-use. If there is any
loss of power to the charger once power is restored, charger will automatically return
to the default settings. Battery selector type would be "GEL".
Battery Voltage — lights when battery voltage is displayed.
Alternator Good — lights when load or no load checks show the alternator is
keeping up with the electrical load.
Equalize — a recessed button used to start the equalize process.
Ensure that all installation and operating instructions and safety
precautions are understood and carefully followed by anyone
installing or using the charger. Follow the steps outlined in "Important
Safety Instructions" at the front of this manual.
Charge Rate Selection
After charger clamps are correctly connected, plug in the charger to a 120 volt AC
outlet. The charger will show a circulating pattern on the Digital Display, indicating
power has been applied. Select the proper charge current rate based on battery size.
Press the 2/10/25 AMP button and the charger will begin charging at 2 amps.
Pressing the 2/10/25 AMP button again will advance the charge rate to 10 amps,
and again to 25 amps. Pressing the switch again will turn OFF the charger output
and the display will show "000".
The only time the selected charge rate does not display at the full selected rate
is when the battery is nearly full and charging at either step two or three. The
display will be showing a reduced charge rate. To return to 2A, press the
2/10/25 AMP button. When the battery is fully charged, the charging complete
and "FUL" is displayed on the Digital Display.
If Digital Display shows "F02" and the Fault indicator lights, the
connection to the battery terminals is bad. Follow the steps outlined in
"Important Safety Instructions" at the front of this manual to
disconnect, clean battery terminals, then reconnect.
If Digital Display shows "F06", the Red (POSITIVE) and Black
(NEGATIVE) clamps are incorrectly connected to battery terminals.
Follow the steps outlined in "Important Safety Instructions" at the
front of this manual to disconnect, then reconnect in correct polarity.
Charging the Battery
1. Press Battery Type selector until desired battery type LED lights.
The default selection is "GEL" type battery.
2. Press 2/10/25 AMP button to begin charging at the 2 amp rate; the unit sounds
a beep and the charging current LED lights. The charger starts charging at 2 amp
rate automatically if 2/10/25 AMP button is not pressed within 3 minutes after
applying AC power.
If the Display on the charger varies between "F03" and the amp rate, the battery
is sulfated and the charger is trying to give it some charge. If after approximately
2 hours the display just shows "F03", then the battery will not charge.
Charger occasionally sounds a beep and displays "0.0" during self-test or
charging stage changes.
3. Pressing the 2/10/25 AMP button again advances charging rate to 10 amps,
and pressing once more advances charging rate to 25 amps. (Pressing the button
again will turn OFF the charger output and the Display will show "000".) This
selection and actual battery charge rate are monitored by the microprocessor,
and the unit will stop charging if the selected rate is too fast or too slow for battery
size or condition.
