iv. Charging Curves Label
Ten charging curves respectively represents different capacities of the Lead-acid battery. I4 means the equalizing current.
Algorithms_105 means the procedure code from the manufacturer. e.g. the charger of Lead-acid flooded battery 48V for
example,

Charging Curves Setup (curve 1~10)

. The LED will flash red several times when AC power is connected, and then the LED will flash green once. The number of red
flashes denotes the present curve. E.g. If the red flashes three times, it means the present curve is curve 3.
2. To choose another curve, please cut off the power supply first, then uncover the label, pressing the button while connecting the
power. If you want to choose curve 3, release the button after the 3rd LED Flash. Now the selected curve (e.g. curve 3) will be
recorded in memory. If you want the charger to work with the selected curve (e.g. curve 3), cut off the power and reconnect it.
3. The charging curves which represent the charging modes for 10 different capacities for Lead-acid battery are customized at
the factory before delivery according to customer demand. Please note the corresponding Lead-acid battery type must be the
same.
VIII Common Faults & Solutions
In case of the charging fails, please examine all the outside lines carefully to make sure that they are connected correctly. Apart
from the circuits failure, please check the failure code of charging LED and handle it according to the following table.

Solutions
▲
Wrong Battery:
Verify the battery voltage range matching with charger or inspect the battery for damage.
▲
Overcharged:
Confirm the battery capacity and the selected curve are matched or if the battery is defective.
▲
Battery Overheated:
Check the temperature at the external thermal sensor. If overheated, the charger will start the battery
protection.
▲
Incorrect AC Input Voltage:
Check that the AC input voltage is in accordance with the requirement.
▲
External Thermal Sensor Fault:
Ensure connect the thermal sensor correctly.
▲
Communication Interface Fault:
Make sure the communication have been correctly connected or if it is damaged.
▲
Charger Overheated:
Check if the ambient temperature is too high or the ventilation is smooth.
▲
Charger Relay Fault:
Repair.
▲
Charger Itself failure:
Repair.
