Instruction and normal responses
Operation as Charger under standard charging mode
Adjust the battery type charging voltage select dipswitch No. 1,2 and 3 to get
the optimum charge to suit your battery specification. Connect the AC input
cable to the utility. Connect the battery to the DC output. Turn On the Power
switch, the “POWER ON” LED lights up. This indicates the device is ready for
charging. The “BULK” LED lights up. This means the battery charger is
beginning at the 1
st
stage of charging
The 1
st
stage is to ensure battery is
always charged at the maximum
charging condition. This is to boost
up the charging cycle and
particularly wake up a weak battery
to absorb energy.
After 10-20 mins, the charger will
switch to 2
nd
stage, the “BULK” LED
remains ON, the battery is charged
at the maximum current to the
battery.
At the 3
rd
stage, the charger will switch to “ABSORPTION” mode, the red LED
goes out and the yellow LED lights up. The charger is delivering constant
voltage to the battery with reduced current.
At the 4
th
stage, the battery has been charged to about 90% of its rated capacity.
The “ABSORPTION” LED goes out and the “FLOAT” LED lights up. The
charging current is decreased and the charging voltage is held at a constant
level. Battery is now under “FLOAT” constant charging. The “FLOAT” charging
voltage can be set by the dipswitch No. 4, 5 and 6.
Operation as Charger under Boost Charging Mode
The device can be set by the charging mode select for Boost charging. It is help
to wake up a low voltage battery to a suitable recharging level. At boost
charging mode, the charger is delivering maximum voltage to boost up the
battery and it will switch to “standard charging mode” automatically after 10-15
mins.
Operation as Power Supply
Set the charging mode select to Power Supply Mode, the device now operates
as a power supply unit. The Bulk and Absorption LED goes out. Switch No. 1,2
and 3 are now disabled. The Power Supply output voltage can be adjusted by
the dipswitch No. 4,5 and 6.
