3.2.1 Controls
Up/Down (VOLTS ADJ.) Arrows
– The Up and Down arrows is used for increasing or decreasing voltage
setting values / Timer selection / Cell Selection / Current Selection.
TIMER Button
– the “TIMER” button is used to “SET/RUN” the timer (1 Hr. -24Hrs #8Hr.) also pressed & hold
for 10 second to switch off the timer.
CELL SELECTION Button
– Used to select the number of cells (Single / Two / Three).
CURRENT SELECTION Button
– Used to select the current mode (5 AMPS CC / 10 AMPS CC / 5 AMPS MAX /
10 AMPS MAX).
START/ENTER Arrows
– Used to run the charger.
3.2.2 LED Indicators
LCD Display
– The LCD display shows the output DC voltage and output DC amperage of the SC3 charger at all
times. Chargers modes and different alarm conditions will be displayed if they should occur.
Charging (Green)
– The charging LED will illuminate and blink during battery charging.
Timer (Yellow)
– The timer LED will illuminate whenever timer is on.
AC On (Green)
– The AC ON LED will illuminate whenever AC voltage is present at the single cell charger.
Single Cell (Red)
– The Single cell LED will illuminate whenever single cell option is selected.
Two/Three Cell (Red)
– The Two/Three Cell LED will illuminate and blink when Two Cell is selected and solid
glow when three cells is selected.
5 AMPS MAX/CC (Red)
– The 5 AMPS MAX/CC LED will illuminate blink when CC mode is selected and solid
glow when MAX mode is selected.
10 AMPS MAX/CC (Red)
– The 10 AMPS MAX/CC LED will illuminate blink when CC mode is selected and solid
glow when MAX mode is selected.
Charger Fail (Red)
– The Charger Fail LED will illuminate and remain solid when the charger is not able to
regulate the output voltage. If charger AC input voltage goes above 155 VAC the Charger Fail LED will
illuminate, “AC MAINS FAIL” and “CHARGER FAIL” will display on the LCD.
5 / 10A MAX. mode
: - During this mode the charger follows a constant voltage charge curve with adjustable
output voltage ranges below:
a. SINGLE CELL mode – 2.20V to 2.55V
b.
c. TWO CELL mode- 4.40V to 5.10V
d. THREE CELL mode- 6.60V to 7.65V
5 / 10A C.C. mode
- During this mode the charger follows a constant charge curve with maximum of 5 amps or
10 amps.
Caution- Battery voltage should be monitored frequently as voltage from charger could rise to the
following fixed voltages:
a. SINGLE CELL mode- 3.0 Volts
b. TWO CELL mode- 5.50 Volts
c. THREE CELL mode- 8.0 Volts
