4. Setup and Installation
The HAZE-UL controller features 13 distinct connectors for various ebike components. Proper installation requires careful attention to each connection.
4.1 Identifying Connectors
The controller comes with a pre-wired harness. Each connector is designed to mate with a specific component on your ebike (e.g., motor, battery, throttle, display, brake levers, pedal assist sensor).
Figure 3: Detailed view of the 13-connector wiring harness.
4.2 Installation Steps
- Disconnect Power: Ensure the ebike battery is completely disconnected before starting.
- Remove Old Controller: Carefully remove the existing controller from your ebike, noting the connections.
- Connect New Controller: Connect each of the 13 connectors from the HAZE-UL controller to the corresponding components on your ebike. Pay close attention to the shape and pin configuration of each connector to ensure correct mating. Common connections include:
- Motor Phase Wires (usually thicker, 3 wires)
- Hall Sensor Wires (usually thinner, 5 wires)
- Battery Power (red/black, thicker)
- Throttle
- Display
- Brake Levers (often two wires per lever)
- Pedal Assist Sensor (PAS)
- Secure Controller: Mount the controller securely in its designated location on the ebike. The aluminum alloy shell is designed for heat dissipation, so ensure adequate airflow.
- Reconnect Battery: Once all connections are verified and secure, reconnect the ebike battery.
- Test Functionality: Power on the ebike and test all functions (throttle, pedal assist, brakes, display) at a low speed in a safe environment.
Important: This controller does not come with a specific wiring diagram. It is crucial to refer to the wiring diagram provided by your ebike manufacturer (Jetson Haze or DYU Y16) for precise connection details. Incorrect wiring can damage the controller or other ebike components.
5. Operating Instructions
The HAZE-UL controller manages the power delivery from your ebike's battery to the motor, based on your input from the throttle and pedal assist sensor. It also interfaces with your ebike's digital display.
- Power On/Off: Use your ebike's main power switch or display button to turn the system on or off.
- Speed Control: The controller supports 3 speed levels. These are typically selected via your ebike's digital display or a dedicated button.
- Throttle Operation: The twist grip throttle allows for direct motor power control. Apply throttle gradually for smooth acceleration.
- Pedal Assist: When pedaling, the pedal assist sensor (PAS) signals the controller to provide motor assistance, making pedaling easier.
- Brake Cut-off: The controller is designed to cut power to the motor when the brake levers are engaged, enhancing safety.
6. Maintenance
The HAZE-UL controller is designed for durability with an aluminum alloy shell for efficient heat dissipation. Minimal maintenance is required:
- Keep Clean: Periodically wipe the controller's exterior with a dry cloth to remove dust and dirt. Avoid using harsh chemicals or solvents.
- Inspect Connections: Regularly check all electrical connections for tightness and signs of wear or corrosion.
- Avoid Overheating: Ensure the controller's mounting location allows for adequate airflow to prevent overheating, especially during prolonged use or in hot weather.
- Protect from Elements: While robust, protect the controller from direct exposure to heavy rain or submersion in water.
7. Troubleshooting
If you encounter issues with your HAZE-UL controller, consider the following:
- No Power: Check battery connection, ebike's main power switch, and ensure all controller power wires are securely connected.
- Motor Not Responding: Verify throttle and PAS connections. Ensure motor phase wires and Hall sensor wires are correctly connected. Check for any error codes on your ebike's display.
- Intermittent Operation: Inspect all connectors for loose connections or corrosion. Ensure wiring is not pinched or damaged.
- No Wiring Diagram: As noted in a user review, a wiring diagram is not included with the controller. If you are experiencing difficulties with installation due to lack of a diagram, please refer to the specific wiring diagram for your Jetson Haze or DYU Y16 ebike model, typically found in your ebike's user manual or available from the ebike manufacturer. If you cannot obtain a diagram, it is highly recommended to seek assistance from a qualified ebike technician.
