Charging CurvesSetup (curve 1~10)：
1.The LEDwill flashredseveraltimeswhenAC poweris connected,and thenthe LEDwillflashgreenonce. The number of red
flashes denotes the presentcurve. E.g. If the redflashes three times,it meansthe presentcurve is curve 3.
2. Tochoose another curve, please cut off thepowersupply first,then uncoverthelabel,pressingthe buttonwhileconnecting the
power.Ifyouwanttochoosecurve3, release thebutton afterthe3rdLEDFlash.Now theselectedcurve(e.g.curve3) will be
recordedin memory.Ifyouwant the chargertoworkwiththeselected curve (e.g. curve 3), cut off the power and reconnectit.

VIII CommonFaults&Solutions
In case of thechargingfails, pleaseexamineallthe outside linescarefully to makesurethattheyareconnectedcorrectly.Apart
from the circuits failure,pleasecheckthe failurecode ofchargingLED and handle itaccording tothefollowing table.

Solutions
▲Wrong Battery: Verifythe batteryvoltage range matchingwithcharger orinspectthe batteryfor damage.
▲Overcharged: Confirm the batterycapacityand theselected curve are matched orifthe batteryis defective.
▲BatteryOverheated: Checkthetemperatureattheexternalthermalsensor.Ifoverheated,thechargerwill start thebattery
protection.
▲Incorrect AC Input Voltage: CheckthattheAC inputvoltage is in accordance withthe requirement.
▲External ThermalSensor Fault: Ensure connect the thermalsensorcorrectly.
▲CommunicationInterfaceFault: Makesure the communication have been correctly connected orifitis damaged.
▲ChargerOverheated: Checkifthe ambient temperatureis toohighor the ventilationis smooth.
▲ChargerRelayFault: Repair.
▲ChargerItself failure: Repair.
