3. Installation and Setup
Before beginning installation, ensure the power source is disconnected to prevent electrical shock or damage to the controller and other components. This controller is designed for hub motor scooters. Verify compatibility with your specific scooter model and motor type before proceeding.
3.1 Wiring Diagram
Refer to the detailed wiring diagram below for proper connection of all components. Incorrect wiring can lead to malfunction or damage.
3.2 Connection Steps
- Power Block: Connect the main power supply from your battery (48V, 60V, or 72V) to the designated "Power block" connectors on the controller. Ensure correct polarity.
- Motor Connections: Connect the motor phase wires and Hall sensor wires to their corresponding ports on the controller. The controller uses Hall sensored communication.
- Throttle: Connect the throttle unit to the "Throttle" input. The default working voltage for the throttle is 0.8V - 3.8V.
- Brake Levers: Connect your brake levers to the "low brake" and "High brake" inputs as per your system's configuration.
- Meter/Display: Connect your display or meter to the "Meter" and "one wire meter" connections if applicable.
- Speed Control: If your system utilizes multiple speed profiles, connect the "3 speed" and "Speed limit" wires accordingly.
- Reverse Function: If your scooter has a reverse function, connect the "Reverse" wire.
- Alarm System: Connect your alarm system to the "ALARM" wire.
- One Key Repair: Utilize the "One key repair" function if your system supports it for diagnostic or reset purposes.
- Ground Wire: Ensure the "E" Earth Wire" (ground) is securely connected to the vehicle's chassis.
- Secure Connections: Double-check all connections for tightness and proper insulation. Use the provided mounting screws to secure the controller in a suitable location, away from excessive heat or moisture.
4. Operating Instructions
Once all connections are securely made and verified, you can power on your scooter. The controller will manage the power delivery to the hub motor based on your throttle input and selected speed settings.
- Power On: Turn on the main power switch of your scooter. The controller will initialize and be ready for operation.
- Throttle Control: Gently twist the throttle to accelerate. The controller translates the throttle voltage (0.8V - 3.8V) into motor speed.
- Braking: Engaging the brake levers will signal the controller to cut power to the motor, ensuring safe deceleration.
- Speed Modes: If connected, utilize the "3 speed" function to switch between different speed profiles (e.g., low, medium, high).
- Reverse: If connected, activate the reverse function as per your scooter's controls for maneuvering.
Always operate your scooter responsibly and in accordance with local regulations and safety guidelines.
5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your FOCAN BLDC motor controller.
- Regular Inspection: Periodically inspect all wiring connections for signs of wear, corrosion, or looseness. Ensure all connectors are firmly seated and free from damage.
- Cleanliness: Keep the controller free from dust, dirt, and debris. While the controller has an IP65 waterproof rating, it is best to avoid direct exposure to heavy water jets or prolonged submersion. Use a dry, soft cloth for cleaning.
- Heat Management: Ensure the controller's aluminum heat sink (Figure 2) is not obstructed to allow for proper heat dissipation. Overheating can reduce performance and lifespan.
- Environmental Protection: Store and operate the scooter in conditions that are within the recommended temperature and humidity ranges. Avoid extreme temperatures and direct sunlight for extended periods.
6. Troubleshooting
If you encounter issues with your controller, refer to the following troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor not responding | No power, loose connections, faulty throttle, motor issue. | Check battery voltage and main power connections. Inspect throttle wiring and functionality. Verify motor connections and test motor if possible. Use "One key repair" if available. |
| Intermittent power/speed | Loose wiring, poor contact, Hall sensor issue, damaged wires. | Secure all connections, especially motor phase and Hall sensor wires. Check for any visible damage to wiring. |
| Controller overheating | Blocked airflow to heat sink, excessive load, short circuit in motor or wiring. | Ensure proper ventilation around the controller. Reduce continuous heavy load. Inspect motor and wiring for short circuits. |
| Incorrect speed or acceleration | Throttle miscalibration, incorrect speed setting, motor incompatibility. | Verify throttle working voltage (0.8V-3.8V). Check "3 speed" or "Speed limit" settings. Ensure motor is compatible with controller's specifications. |
6.1 Frequently Asked Questions (FAQ)
- Q: Does this controller have Bluetooth connectivity?
A: No, this FOCAN BLDC Motor Controller model FCY721812 does not feature Bluetooth connectivity. It is a standard wired motor controller. - Q: Is this controller compatible with my specific scooter model (e.g., Kukirin G2 2024)?
A: Compatibility depends on your scooter's battery voltage, motor power, and wiring configuration. Please compare the specifications of this controller (48V/60V/72V, 500W-1KW, 35A max current, Hall sensored) with your scooter's requirements before purchase and installation.
7. User Tips
- Voltage Matching: Always ensure your battery voltage precisely matches the controller's supported voltage (48V, 60V, or 72V) for optimal performance and to prevent irreversible damage to both components.
- Professional Installation: If you are unsure about any wiring or installation steps, it is highly recommended to seek assistance from a qualified technician to avoid potential damage, electrical hazards, or improper functionality.
- Initial Test: After installation, perform a low-speed test in a safe, open area to confirm all functions are working correctly (throttle response, braking, speed modes) before full operation.
- Secure Mounting: Mount the controller securely to prevent vibrations and physical damage. Ensure it is in a location that allows for adequate airflow to the heat sink.
