4.2 Installation Steps

1. Mount the LCD Display: Securely attach the LCD display unit to the handlebar using the provided clamp and screws. Ensure it is positioned for easy viewing and access to buttons.
2. Mount the Controllers: Find a suitable, protected location on your vehicle for the two brushless controllers. Ensure they are securely fastened and have adequate ventilation.
3. Connect Power: Connect the main power wires from your vehicle's battery to the power input of each controller. Pay close attention to positive and negative terminals.
4. Connect Motors: Connect the phase wires (usually three thick wires) and Hall sensor wires (usually five thin wires) from each motor to its respective controller. Match colors carefully.
5. Connect Display: Connect the communication cable from the LCD display to the designated port on one of the controllers (typically the main controller).
6. Connect Peripherals: Connect other peripherals such as the throttle, brake levers (if they have cut-off switches), and any other accessories to the appropriate ports on the controllers.
7. Secure Wiring: Route and secure all wiring to prevent snagging, pinching, or damage during operation. Use zip ties or cable wraps as needed.
8. Initial Test: Before full operation, perform a low-power test to ensure all components are functioning correctly. Check for any unusual noises or behavior.

5. Operating Instructions

Once installed, the system is ready for operation. Familiarize yourself with the LCD display and controller functions.

5.1 Power On/Off

• Power On: Press and hold the power button on the LCD display unit until the screen illuminates.
• Power Off: Press and hold the power button again until the display turns off.

5.2 LCD Display Functions

The LCD display provides critical information and allows for mode selection.

• Speed Display: Shows current speed (e.g., km/h or mph).
• Battery Level Indicator: Displays the remaining battery charge.
• Mode Selection: Use the 'MODE' button to cycle through different riding modes or display parameters (e.g., Odometer, Trip Distance, Voltage).
• Voltage Adjustment: The display supports a voltage range of 36V-60V. Specific instructions for adjusting or confirming the voltage setting may be available through the display's menu system. Refer to the display's dedicated manual if available for detailed parameter settings.

6. Maintenance

Regular maintenance helps ensure the longevity and reliable performance of your controller and display kit.

• Cleaning: Keep the LCD display and controllers clean. Use a soft, dry cloth to wipe away dust and dirt. Avoid using harsh chemicals or abrasive materials.
• Connection Inspection: Periodically check all electrical connections for tightness and signs of corrosion or wear. Re-secure any loose connections.
• Cable Integrity: Inspect all cables and wiring for cuts, fraying, or damage. Replace damaged cables immediately to prevent electrical shorts.
• Environmental Protection: While the components are designed for outdoor use, prolonged exposure to heavy rain or extreme temperatures should be avoided. Consider additional protective measures if operating in harsh conditions.

7. Troubleshooting

This section addresses common issues you might encounter. If problems persist, consult a professional technician.

7.1 Display Not Powering On

• Check Battery: Ensure the vehicle's battery is charged and properly connected.
• Check Power Connections: Verify that the power wires to the controllers and the display's communication cable are securely connected.
• Inspect Wiring: Look for any visible damage to the wiring that might prevent power flow.

7.2 Motors Not Responding

• Check Throttle: Ensure the throttle is correctly connected and functioning.
• Verify Motor Connections: Confirm that the phase wires and Hall sensor wires from the motors are correctly and securely connected to the controllers.
• Controller Status: Check if the controllers are receiving power and if there are any diagnostic indicators (if applicable).
• Brake Cut-off: If your brake levers have cut-off switches, ensure they are not engaged, as this will prevent motor operation.
