EQUALIZING CHARGE (EXB Option)
The truck-mount type charger automatically gives an equalizing
charge to the battery with the microprocessor. Therefore, there is
usually no need for the operator to do anything. However, give an
equalizing charge manually in any of the following cases.
e The battery has been overdischarged.
e Purified water has been added.
* The discrepancy in specific gravity among cells is more than
0.02 (at the electrolyte temperature of 20°С).
Manual equalizing charge consists of normal charge plus super
equalizing charge.
When performing manual equalizing charge, give normal charge
to the battery and then give super equalizing charge by pressing
the "Super equalizing charge" button.
While super equalizing charge is in progress, the "Charging in
progress" lamp and "Super equalizing charge" lamp on the charger
control panel stay on.
AUXILIARY CHARGE (EXB Option)
• if the residual capacity on the LCD meter unit shows level З or
less after the day's work or each shift, give the battery an auxiliary
charge during a break. The procedure for giving a cycle charge
is the same as the normal charge.
e If you want to stop an auxiliary charge, make sure to press the
"Stop" button, turn the power supply switch off and then remove
the charger cables.
HANDLING THE BATTERY
SUPER EQUALIZING CHARGE (EXB Option)
Super equalizing charge is composed of ordinary equalizing charge
and automatic auxiliary charge. Since auxiliary charge is
automatically carried out every 24 hours after an equalizing charge
is carried out, you don't need to worry about a low battery voltage
even after the track is not used for several days.
Super equalizing charge can be carried out by pressing the "Super
equalizing charge" button after normal charge is completed.
The "Super equalizing charge" lamp does not go out even after
charging is automatically completed ("Charging in progress" lamp
goes out). Turn off the lamp in the following manner:
e When the "Charging in progress" lamp is on, press the "Stop"
button.
• When the "Charging in progress" lamp is off, press the "Super
equalizing charge" button or turn the key switch on.
АҒ NOTE
Frequent full-discharges of the battery will shorten the battery
service life. If your task requires full discharge of the battery
frequently, it is advisable to use a high-capacity battery or have
a spare battery.
Lamp blinking while charging
If the "Charging in progress" lamp on the control panel is blinking,
it indicates that charging has not been completed successfully.
* The 2nd timer of the charger functions and charging is forcefully
discontinued in 15 to 17 hours.
• The electric power failure lasts for more than 120 hours while
charging.
^ NOTE
While the "Charging in progress" lamp is blinking, no charging is
performed. It is necessary to check the cause of trouble and fix it.
For the procedure for troubleshooting, consult your local TCM dealer.
