3. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your motor controller. It is recommended that installation be performed by a qualified technician.

3.1 Component Identification

The controller features main power terminals (B+, B-) and motor phase terminals (U, V, W). Additionally, there are multiple smaller connectors for various signal inputs and outputs, including:

• Throttle input
• Hall sensor inputs
• Ignition switch
• Brake signals
• Speed limit switch
• Communication port for programming (refer to Figure 4)

3.2 Wiring Instructions

1. Mounting: Securely mount the controller in a location that allows for adequate ventilation and protection from moisture and physical damage. Ensure the heat sink fins (Figure 5) are not obstructed.
2. Main Power Connection: Connect the main battery positive (B+) and negative (B-) terminals to the corresponding terminals on the controller. Ensure correct polarity and use appropriate gauge wiring capable of handling 150A.
3. Motor Phase Connection: Connect the motor's U, V, and W phase wires to the corresponding U, V, and W terminals on the controller.
4. Hall Sensor Connection: Connect the motor's Hall sensor wires to the dedicated Hall sensor input on the controller.
5. Signal Wire Connections: Connect the throttle, brake, ignition, and any other auxiliary signal wires according to your vehicle's wiring diagram.
6. Software Connection: For initial setup and configuration, connect the controller to a computer using the appropriate communication cable and the SP GUI Tool (Figure 4).

3.3 Initial Configuration (SP GUI Tool)

The controller's parameters can be configured using the SP GUI Tool. This software allows for detailed adjustments to motor, battery, current, and throttle settings, as well as enabling various functions.

Steps for Configuration:

1. Connect the controller to your computer via the designated communication port.
2. Launch the SP GUI Tool software.
3. Use the 'Connect' button to establish communication with the controller.
4. Navigate through 'Basic Setting' and 'Function Setting' menus to adjust parameters as needed for your specific motor and vehicle setup.
5. After making changes, 'Upload' the settings to the controller.
6. Always 'Download' current settings before making changes to create a backup.

Warning: Incorrect configuration can damage the motor or controller. Consult a professional if unsure.

4. Operating Instructions

Once installed and configured, the controller manages the motor's operation based on user input (e.g., throttle) and programmed settings.

4.1 Basic Operation

• Power On: Turn on the vehicle's ignition. The controller will perform a self-check.
• Throttle Control: Apply throttle gradually to accelerate. The controller's 'Throttle' setting in the GUI tool determines response characteristics.
• Braking: Engage the brake lever. The controller supports Electronic Braking System (EBS) if configured, providing regenerative braking or electronic assistance.

4.2 Advanced Functions (Configurable via SP GUI Tool)

The DK72420S controller supports various advanced functions to enhance ride experience and safety:

• Ride Mode: Adjust power delivery and response for different riding styles (e.g., Eco, Sport).
• Anti Theft: Enable security features to prevent unauthorized use.
• EBS (Electronic Braking System): Configure braking strength and characteristics.
• Three Speed: Cycle through predefined speed limits.
• Speed Limit: Set a maximum speed for the vehicle.
• Cruise: Maintain a constant speed without continuous throttle input.
• Reverse: Enable reverse motion for maneuvering.
• Parking: Engage a parking brake function.
• Charge Protection: Manage battery charging and discharge cycles.
• Side Stand: Safety feature to prevent motor operation when the side stand is down.
• TCS (Traction Control System): Helps maintain traction during acceleration.
• HDC (Hill Descent Control): Assists in controlling speed during downhill travel.
• ARF: (Specific function details may vary, refer to software documentation for full details).

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your motor controller.

• Keep Clean and Dry: Ensure the controller is free from dust, dirt, and moisture. Avoid exposing it to water or extreme humidity.
• Inspect Connections: Periodically check all electrical connections (power, motor, signal wires) for tightness and corrosion. Loose connections can lead to overheating or intermittent operation.
• Thermal Management: Ensure the heat sink fins are clean and unobstructed to allow for proper heat dissipation. Overheating can severely damage the controller.
• Software Updates: Check for any available software or firmware updates for the SP GUI Tool or the controller itself, as these may improve performance or add new features.

Warning: Do not attempt to open the controller casing. Tampering with the internal components will void any warranty and may cause electric shock or damage.

6. Troubleshooting

If you encounter issues with your DKYS DK72420S motor controller, refer to the following common troubleshooting steps:

• No Power:
  • Check battery connections and charge level.
  • Verify ignition switch is functioning correctly.
  • Inspect main power cables for damage or loose connections.
• Motor Not Responding:
  • Check throttle connection and functionality.
  • Verify motor phase and Hall sensor connections.
  • Ensure the controller is properly configured using the SP GUI Tool (e.g., motor type, Hall sensor settings).
• Intermittent Operation:
  • Inspect all wiring for loose connections or frayed wires.
  • Check for signs of overheating on the controller.
  • Ensure the controller is not exposed to excessive vibration or moisture.
• Unusual Noises or Vibrations:
  • This could indicate an issue with the motor itself or incorrect motor parameter settings in the SP GUI Tool.
  • Re-check motor phase and Hall sensor connections.
• Error Codes: If your vehicle's display shows an error code, consult the SP GUI Tool or your vehicle's specific manual for interpretation.

If the problem persists after attempting these steps, contact customer support for further assistance.
