3.2 Cyfarwyddiadau Gwifro

Before beginning, ensure the battery is disconnected to prevent electrical shock or damage to components. Connect the wires according to the following guide:

1. Motor Line: Connect the three thick wires (typically green, yellow, blue) from the controller to the corresponding phase wires of your brushless motor. Ensure colors match.
2. Positive Electrode (Battery +): Connect the thick red wire from the controller to the positive terminal of your battery.
3. Negative Electrode (Battery -): Connect the thick black wire from the controller to the negative terminal of your battery.
4. Lock (Ignition): Connect the ignition wire from your vehicle's key switch or power lock to this wire on the controller. This typically enables or disables power to the controller.
5. Alarm Power Supply: Connect to your alarm system's power input, if applicable.
6. High Brake: Connect to the high-level brake signal wire from your brake levers. This signal typically cuts motor power when brakes are applied.
7. Study Wire (Self-Learning): These two wires (often white or blue) are used for initial motor phase learning. Connect them together briefly, turn on the power, and the motor should spin. If it spins in the wrong direction, disconnect, reconnect, and try again. Once the motor spins correctly, disconnect these wires.
8. Hall Sensor Wires: Connect the thin wires (typically red, black, blue, green, yellow) from the controller to the corresponding Hall sensor wires of your brushless motor. These provide feedback on motor position.
9. Mordaith: Connect to the cruise control switch, if your system supports this feature.
10. Low Brake: Connect to the low-level brake signal wire from your brake levers. This signal typically cuts motor power when brakes are applied.
11. Gwrthdroi: Connect to a reverse switch, if your vehicle requires a reverse function.
12. Alarm Wire: Connect to the signal wire from your alarm system.
13. LCD Display / Instruments: Connect to your vehicle's LCD display or instrument panel for speed, battery level, and other data.
14. Throttle: Connect the throttle input wires (typically red, black, green) to your throttle assembly. Red is usually positive, black is negative, and green is the signal wire.
15. Three Speed: Connect to a three-speed switch, if your system allows for different speed modes.

After all connections are made, double-check each connection for security and correct polarity before reconnecting the battery.

4. Cyfarwyddiadau Gweithredu

Once the controller is correctly installed and the battery is connected, the system is ready for operation.

• Pŵer Ymlaen: Turn the ignition key or power switch to the "ON" position. The display (if connected) should illuminate.
• Rheoli Throttle: Gently twist the throttle to engage the motor. The motor speed will increase proportionally with the throttle input.
• Brecio: Applying the brake levers will cut power to the motor, ensuring safe deceleration.
• Speed Modes (if applicable): Use the three-speed switch to select desired speed modes (e.g., low, medium, high).
• Cruise Control (if applicable): Activate the cruise control switch to maintain a constant speed.
• Pwer i ffwrdd: Turn the ignition key or power switch to the "OFF" position when finished operating the vehicle.

The WFLNHB motor controller is designed for durability and requires minimal maintenance. However, regular checks can extend its lifespan and ensure optimal performance.

• Cadw'n Lân: Periodically clean the exterior of the controller to prevent dust and debris buildup, which can hinder heat dissipation. Use a dry, soft cloth.
• Gwirio Cysylltiadau: Regularly inspect all wire connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent operation or damage.
• Osgoi Amlygiad Dŵr: Er bod yr alwminiwm casing offers some protection, avoid direct exposure to heavy rain or submersion in water to prevent internal damage.
• Rheoli Tymheredd: Ensure the controller is mounted in a location with adequate airflow to prevent overheating, especially during prolonged high-power operation.
• Difrod Corfforol: Archwiliwch y casing for any signs of physical damage. A damaged casing may compromise the internal components.
