This charger is programmable for standard lead-acid,
heavy duty lead-acid batteries . The setting is displayed
using the blink on/off method each time the battery
charger is connected to an aC power supply and the
charger is disconnected from the batteries .
The standard battery charger utilizes a single-Led
display . The Led flashes green during the charging cycle
and changes to solid green when the charging cycle is
complete .

Maintenance Instructions
1. For flooded lead-acid batteries, regularly check water levels of each battery cell after charging
and add distilled water as required to level specified by battery manufacturer. Follow the
maintenance and safety instructions recommended by the battery manufacturer.
2. Make sure charger connections to battery terminals are tight and clean.
3. Do not expose charger to oil, dirt, mud or direct heavy water spray when cleaning vehicle.

Battery High Voltage
Check battery size and condition and
reset charger (interrupt AC power for
15 seconds).
Battery Low Voltage
Check battery size and condition and
reset charger (interrupt AC power for
15 seconds).
Charge Timeout caused by
battery pack not reaching
required voltage. Charger
output was reduced due to
high temperatures
Check connections.
Operate charger at a lower ambient
temperature.
Check Battery: battery could
not be trickle charged up to
minimum voltage
Check for shorted or damaged cells.
Over-Temperature: Charger
shut down due to high internal
temperature.
Ensure sufficient cooling air flow and
reset charger (interrupt AC power for
15 seconds).
Charger Internal Fault
Reset charger (interrupt AC power
for 15 seconds). Return to qualified
service depot if fault persists.

2 . Connect charger to aC supply and observe the
Led display . It will blink on/off to indicate the cur-
rent battery charger setting for 11 seconds .
3 . Connect the battery charger to the batteries for 2
seconds and then disconnect from the batteries,
during the 11 second window, to advance to the
next highest setting .
NOTE: The 11 second window expands to 30 seconds after
the first change has been made.
4 . wait 45 seconds after a change has been made to
save the new charger setting .
NOTE: There are 10 total algorithms. The advancement
sequence increases each time and then loops back to #1.
a flashing red Led indicates a charger error . Count the
number of flashes separated by a long pause and then
use the table below to identify a possible cause .
