OPERATION OF THE COMPLETELY AUTOMATIC
BATTERY CHARGER
This charger is equipped with an electronic circuit that
will completely recharge the batteries and automatically
turn off after the charge cycle is complete.
The function of the LED indicators is as follows:
When the AC power is connected to the charger, the
LED’s will flash several times then flash independently
to check the light circuits. After the flashing sequence
is complete the “INCOMPLETE” light will come on. Five
seconds later, the “CHARGER ON” light will come on
and at the same time, the ammeter will indicate how
much current is going to the batteries.
As the charge cycle continues, which can last between
1-1/2 hours and 16 hours for a complete cycle,
depending on the state of charge of the batteries, the
“80% CHARGE” light will come on and the
“INCOMPLETE” light will go off. When voltage of the
batteries reaches approximately 60 volts, the “80%
CHARGE” light will go off and the “CHARGE
COMPLETE” light will come on. This light will remain
on even after the charger is turned off by the electronic
control. After the charger turns off, the “CHARGE
COMPLETE” light will indicate to the operator that the
batteries are healthy and are fully charged.
If the “80% CHARGE” light continues to stay on after
the charge cycle is complete, this indicates to the
operator that the batteries are not capable of attaining a
full charge.
If the “INCOMPLETE” light remains on after the charge
cycle is complete, this indicates to the operator that the
batteries are not capable of attaining even an 80%
charge.
If either the “80% CHARGE” or “INCOMPLETE” light
remain on after the charge cycle is complete, the
batteries should be inspected for problems.
Your standard good watering procedures should be used
at all times.
