Instal·lació i cablejat

Careful wiring is essential for proper function and safety. Follow these steps for connecting the controller and LCD display.

Controller Wiring Connections

Figura 2: Detallada view of the controller's wiring harness with numbered labels indicating each connection point.

1. Phase Line Connection: Connect the motor's phase lines to the controller's phase lines, matching colors (e.g., green to green, blue to blue, yellow to yellow).
2. Hall Line Connection: Connect the motor's Hall sensor lines to the controller's Hall lines, matching colors. Ensure your motor has 5 Hall wires.
3. Connexió de la bateria: Connect the battery lines. The red wire is for battery positive (+), and the black wire is for battery negative (-). Ensure correct polarity.
4. LCD Line and Ignition Switch: Connect the controller's LCD line. If your throttle does not have an ignition switch, the two ignition wires on the controller must be shorted together to power on the system.
5. Intelligent Recognition (Self-Learning):
   • Apagueu l'alimentació.
   • Connect the two intelligent recognition lines together.
   • Turn on the power. The wheel will rotate forward or reverse.
   • If the wheel rotates forward, separate the intelligent recognition lines.
   • If the wheel rotates in reverse, separate the intelligent recognition lines, then connect them together again. If the wheel now rotates forward, separate the intelligent recognition lines.
   • This function allows the controller to automatically identify the battery voltage and motor rotation direction.
   • Nota: When using the throttle, the intelligent recognition lines must be separated.
6. Altres connexions: Connect other functions as needed, such as high-level brake, brake light power, throttle handle, reverse gear, low brake, linear brake (thumb brake), PAS, headlight/taillight power, and regenerative brake. Refer to Figure 2 for connection points.

LCD 5-Wire Interface

• Vermell: Cable d'alimentació del comptador
• Blau: Cable de control de potència del controlador
• Negre: Instrument ground wire
• Verd: Línia de recepció de dades del comptador
• groc: Data transmission line of the meter

Botó Introducció

The display features an 'M' (Mode/Power) button, an 'Up' button, and a 'Down' button. Operations are categorized into short press, long press, and combination long press.

• Premsa curta: Used for quick actions (e.g., changing assist/speed gear, switching display data).
• Single Button Long Press: Used for mode or state switching (e.g., turning display on/off).
• Combination Key Long Press: Used for parameter settings to prevent accidental changes.

Operacions específiques

1. Encès/apagat: Long press the 'M' (power) button to turn the display on or off.
2. Canvia els modes de visualització: After the display is on, short press the 'M' button to cycle through different display data (e.g., ODO, Trip, Voltagi).
3. Modify Assist Ratio/Electric Gear:
   • Short press the 'Up' button to increase the assist level.
   • Short press the 'Down' button to decrease the assist level.
4. Switch Speed Display Mode: Long press the 'M' and 'Up' buttons simultaneously to switch between different speed display modes (e.g., average speed, max speed).
5. Turn On/Off Headlights: Long press the 'Up' button to toggle the headlights on or off.

Parameter Settings (P01-P18)

To enter the parameter setting interface, press and hold the 'Up' and 'Down' buttons simultaneously. Use the 'Up' or 'Down' buttons to adjust values. Short press the 'M' button to move to the next parameter. To exit and save, long press 'Up' and 'Down' simultaneously, or the system will auto-save and exit after 10 seconds of inactivity.

Nota: Due to potential production batch differences, some parameters may vary slightly from this description but will not affect general usage.
