1.1.4 CHARGER OPERATION
(1) When the power supply switch to the battery charger is turned on, the charging circuit inside
the LCD panel is activated.
(2) When the START button is pressed, a circuit consisting of the CM contactor, thermal relay TH
and CN1-8 terminals of the LCD panel is completed to activate the CM contactor.
(3) When the CM contactor is activated to connect the power supply to the transformer, the LED1
turns on and the fail timer starts counting down the time and thus charging operation starts.
The fail timer is usually set to 15 hours for normal charge.
(4) When the battery voltage rises up to the preset voltage, the control circuit inside the LCD
panel detects the voltage level and then timer starts counting down the time.
This timer is automatically set to a proper amount of time according to how much the battery
has been discharged.
(5) When the time set to the timer expires, the CM contactor opens to finishing charging.
