Preparation – Before Charging
General Checking
•
Check thoroughly the charger itself including all the cables show no damages
•
Take into consideration the charging instruction issued by the battery manufacturer
Charging Cable – Polarity Checking
WARNING: Check the polarity before mounting onto a plug:
•
Red cable = Plus (+)
•
Black cable = Minus (-)
DC Mains Supply Checking
•
Make sure the DC cable must not be cut, shortened or extended under any circumstances
•
Make sure the mains supply complies with the technical specification requirements of the charger
Before Connecting the Charger to the Battery
•
<For models targeting lead-acid batteries> First connect charger to the mains to select the appropriate loader, then disconnect from the
mains and connect the temperature sensor to the battery (the assembly depends on the battery manufacturer)
•
<For all models> Make sure the charger is switched off and disconnected from the mains supply
•
Then connect the terminals of the charger to the battery (Red cable to the positive (+) terminal of the battery; then Black cable to the negative
(-) terminal)
•
If the battery is built-in within a vehicle, the Black cable can be connected to the negative (-) terminal of the battery or the body of the vehicle;
make sure the connection is done with a safe distance from the fuel line and take into consideration of the battery and vehicle manufacturer
•
Finally connect the power cable of the charger to the mains supply, and switch on the charger
For Models Targeting Lead-based Batteries
•
Select the desired charge profile:
With proper connection, the LED of the currently active charge profile lights up continuously. To change the charge profile, press and hold the
"Press Button" for 5 seconds, the LED of the active profile will then change to slow flashing. Now you can switch between the different charge
profiles by briefly pressing the "Press Button". When the desired profile is selected, confirm the selection by pressing the "Press Button” again
for 5 seconds, the LED of the selected charge profile changes to steady lighting.
•
Select the Power Supply Mode:
Follow the steps above to select a charge profile; the Power Supply Mode is signaled by the lighting up of all the 4 charge profile LEDs.
•
The latest selected charge profile will be kept unless you change it
Charging the Battery
The charging process starts automatically and runs through the following stages:
Getting Ready: Auto Wake-up
Yellow Charge LED and Green Full LED are blinking alternately. During this pre-charge phase, the charger sends out series of controlled current
pulses to reactivate the BMS (if any) and bring in a voltage to the battery for getting ready for the charging process. If no battery or defected battery
pack is connected, the Red Error LED blinks. In this case, switch off the charger and check the battery pack.
Phase 1: Soft Start
Yellow Charge LED keeps on lighting. The charger regulates the initial charging current to better prolong the battery life.
Phase 2: Constant Current Charging
Yellow Charge LED blinks slowly. The battery is being charged to 80% of its capacity at this stage.
Phase 3: Constant Voltage Charging
Yellow Charge LED blinks quickly. The battery is being charged to its maximum capacity. When the Green Full LED turns on, the charger can now be
disconnected from the battery.
Phase 4: Float Charging (for lead-based batteries only) or Auto Restart
Green Full LED keeps on lighting indicate the battery has reached its full capacity. If the battery keeps connecting to the charger, auto restart of the
charging cycle will take place after 30 days or when the battery voltage has dropped to under 3.6V/cell (Li-ion Battery) or 3.2V/cell (LiFePO4 Battery).
Disconnect the Charger from the Battery:
1.
First, disconnect the charger from the mains supply
2.
Then, disconnect the charger from the battery
After disconnecting the charger from the mains, please wait at least 5 seconds to reactivate the charger if in need – otherwise damages may be
resulted.
