Charge Indicator - Big Joe PDBB-20-T12 Operation, Maintenance, Repair Parts List

5. The battery charger is fully automatic and will
cycle automatically (depending on amount of
charge needed). Charge status can be observed
as follows (Refer to
a. The top three LED's indicate charger status.
At start of charge the RED (Charge) LED will
be ON indicating the batteries are connected
and charging. After the batteries charge to
approximately 80% the Yellow LED comes
ON. After a time (1 hour minimum) the Green
LED comes ON indicating battery ready.
NOTE: The battery charger includes an override
timer which terminates the charge if the cycle
does not complete after 18 hours of charging.
This time-out condition is indicated by the
green LED flashing off and on, and it indi-
cates a fault condition which should be inves-
tigated. This will occur if the charger cannot
raise the battery voltage to the preset voltage
limit. Possible causes indicate a battery fault,
a charger fault, low AC power supply voltage,
or excessive discharge. The override timer

Figure 3-1):
can be reset by switching the AC power to the
charger off.
b. The lower four red LED's indicate current
flow. Normally at start of charge, if the batter-
ies are discharged, all four red LEDs will be
on indicating maximum 25A charge current.
As the batteries charge the current drops and
the LEDs go OFF as the current drops to
20A, 15A, 10A and 5A respectively.
