4. Setup and Wiring

Careful wiring is crucial for the correct and safe operation of your controller. Refer to the wiring diagram below for connections. Ensure all connections are secure before applying power.

4.1 Wiring Connections Overview:

• Battery Connections: Connect the main battery positive (Battery+) and negative (Battery-) terminals to the corresponding D+ and D- terminals on the controller.
• Motor Phase Wires: Connect the motor's U, V, W phase wires to the corresponding U, V, W terminals on the controller.
• Hall Sensor Wires: Connect the motor's Hall sensor wires (Blue Hall U, Green Hall V, Yellow Hall W, Red 5V, Black Ground) to the Hall sensor input.
• Throttle: Connect the throttle signal (Gray), 5V supply (Red), and Ground (Black) wires.
• Brake Signals:
  • High Brake (12V): Connect the purple E-brake wire to a 12V source or leave unconnected if not used.
  • Low Brake (0V): Connect the yellow low brake wire to ground or leave unconnected if not used.
  • Brake Throttle Signal: Connect the brown 0-5V brake throttle signal.
• Ignition: Connect the orange ignition wire to the battery positive (+) terminal to power on the controller.
• Speed Modes:
  • High Speed: Connect the pink wire to ground or leave unconnected.
  • Low Speed: Connect the transparent wire to ground or leave unconnected.
• Reverse: Connect the white reverse wire to ground or leave unconnected.
• Motor Temperature Sensor: Connect the white motor temperature sensor wire.
• Programming Port: Use the provided USB cable to connect to a PC or phone for programming.

4.2 Indicators:

• Red LED: 5V indicator.
• Green LED: Error and fault indicator.

5. Operation

Once properly wired, the controller manages the motor's operation based on throttle input and programmed settings. The controller supports various functions for enhanced control and performance.

5.1 Basic Functions:

• Throttle Control: The 0-5V throttle input allows for variable speed control.
• Ignition: Power on the controller by connecting the ignition wire to the battery positive.
• Braking: Utilize High Brake (12V) or Low Brake (0V) inputs for braking functionality. The E-Brake (0-5V) provides regenerative braking capabilities.
• Three Speed Function: Switch between different speed modes (High, Low, or a third speed if configured) using the dedicated wires.
• Reverse Function: Engage reverse motion via the reverse wire.

5.2 Advanced Programming:

The controller can be programmed via PC software or a mobile application to fine-tune parameters such as current limits, voltage settings, motor direction, and speed limits. Use the provided USB cable for connection.

Key programmable parameters include:

• Basic Parameters: DC current limit, over-voltage/under-voltage protection, rated DC current, rated phase current, protected phase current.
• Function Parameters: Electric brake settings, 3-speed boost, cruise control, reverse speed limit, flux weakening, regenerative charge settings.
• Motor Parameters: Motor direction, motor pole pairs, speed limit mode, motor limit speed, low/middle speed set points.

6. Maintenance

To ensure the longevity and optimal performance of your Sabvoton controller, follow these general maintenance guidelines:

• Keep Dry: Protect the controller from water and excessive moisture. While the aluminum case offers some protection, it is not fully waterproof.
• Keep Clean: Periodically clean the exterior of the controller to prevent dust and dirt buildup, especially on the heat sink fins, which can impede cooling.
• Check Connections: Regularly inspect all wiring connections for tightness and signs of wear or corrosion. Loose connections can lead to intermittent operation or damage.
• Avoid Overheating: Ensure adequate airflow around the controller, especially during high-power operation, to prevent overheating.
• Software Updates: Check the manufacturer's website or app for any available firmware updates that may improve performance or address known issues.

7. Troubleshooting

If you encounter issues with your controller, refer to the following common problems and solutions:

7.1 Common Error Indicators:

The green LED on the controller indicates errors. Refer to the software interface for specific fault codes or messages, which may include:

• Motor Fault (e.g., reverse, brake, boost, cruise)
• Overtemperature
• Overspeed
• Overcurrent
• Undervoltage

7.2 General Troubleshooting Steps:

• No Power: Check ignition wire connection and battery voltage. Ensure the battery is charged and properly connected.
• Motor Not Responding: Verify all motor phase and Hall sensor connections. Check throttle signal. Ensure the controller is powered on.
• Intermittent Operation: Inspect all wiring for loose connections or damaged insulation. Check for signs of overheating.
• Incorrect Speed/Behavior: Connect to the programming software (PC or App) and verify all parameters are set correctly for your motor and desired operation.
• Compatibility Issues: Ensure your motor is a Spoke/In-wheel/Hub type with a 120° phase angle and not a Mid-Drive motor. Confirm your display is a Hall sensor type, not a TFT display.

If problems persist after basic troubleshooting, contact customer support for further assistance.

8. User Tips

• Motor Compatibility: This controller is specifically designed for Spoke/In-wheel/Hub motors with a 120° phase angle. Using it with a Mid-Drive motor may lead to improper function.
• Display Compatibility: Ensure you use a Hall sensor display. TFT displays (such as UKC1/750C) are not compatible with this controller.
• Harness: The package includes plugs and pins, but a complete wiring harness may need to be sourced separately depending on your specific application. Review the wiring diagram carefully to understand all necessary connections.
• Professional Installation: If you lack experience with electric kit assembly, consider seeking professional assistance for installation to avoid potential damage or safety issues.
