KT E-Bike kontrolagailuaren argibideen eskuliburua

1. Sarrera

This manual provides detailed instructions for the installation, operation, and maintenance of your KT 36V/48V 15A brushless e-bike controller. Designed for 250W to 350W electric bicycles, this controller offers reliable performance and is available in waterproof (WP) and standard (SM) plug configurations, as well as Sinewave and Squarewave types. Please read this manual thoroughly before installation and use to ensure proper function and safety.

2. Segurtasun informazioa

• Sute-arriskua: Please mind potential fire risk and strictly follow the instruction manual for charging and storage of your e-bike battery and related components.
• Light/Lamp Unekoa: When connecting a light or lamp to the KT controller, ensure its current draw is approximately 70 mA (less than 100 mA). Exceeding 100 mA can damage the controller. It is recommended not to use front and rear lights simultaneously if their combined current exceeds this limit.
• Instalazio profesionala: If you are unsure about any installation steps, consult a qualified e-bike technician.
• Waterproof Connectors: While the controller is waterproof, ensure all connections are properly sealed and secured to prevent water ingress.

3. Produktua amaitu daview

The KT-15A controller is a key component for your e-bike's electrical system, managing power delivery to the brushless motor. It is compatible exclusively with KT brand displays that share the same communication protocol.

Figure 3.1: KT E-Bike Controller (250W/350W) with connectors.

The controller features a robust silver casing and is designed for durability. It comes in different plug types (Waterproof 'WP' and Standard 'SM') and waveform types (Sinewave for smoother, quieter operation, or Squarewave).

4. Instalazioa eta kableatzea

Carefully follow the wiring diagrams below based on your controller's plug type (WP, SM, or WP+SM) and desired functions. Ensure all connections are secure before powering on the system.

4.1. General Wiring Considerations

• Bateragarritasuna: This KT controller is only compatible with KT displays. Ensure your display uses the same communication protocol.
• Waterproof Connectors: If you have a waterproof system, verify that your existing cable brand (e.g., Julet, Higo, YLS) matches the controller's connectors. While many are compatible, slight variations in line sequence can occur.
• Kablearen luzera: The cable lengths are approximately 10-13cm for individual connections.

5. Funtzionamendua

Once correctly installed, the KT controller manages the power flow to your e-bike's motor based on your input from the display, throttle, and PAS (Pedal Assist System).

• Abiadura kontrola: The speed is set via the display or throttle, typically within a 1-4.2V range.
• Brake Input: The controller supports low-level brake input, which cuts motor power when brakes are applied.
• Vol. Baxuatage Babesa: The controller includes a low voltage protection feature, activating at DC30/40±0.5V to prevent battery over-discharge.
• Sinewave vs. Squarewave: Sinewave controllers generally provide a smoother and quieter riding experience compared to Squarewave controllers.

6. Mantentzea

To ensure the longevity and optimal performance of your KT e-bike controller, consider the following maintenance tips:

• Mantendu lehorra: Although some versions are waterproof, it's best to keep the controller as dry as possible. Avoid prolonged exposure to heavy rain or submersion.
• Konexio garbiak: Periodically check and clean all electrical connections to prevent corrosion and ensure good conductivity.
• Muntaketa segurua: Ensure the controller is securely mounted to prevent vibrations and physical damage.
• Saihestu gehiegi berotzea: Ensure adequate airflow around the controller, especially during extended use, to prevent overheating.

7. Arazoak

• Controller Damage from Lights: If your controller is damaged after connecting lights, verify that the light's current draw is less than 100 mA. Using high-current lights can overload and damage the controller.
• Bateraezintasun arazoak: If the controller does not function with your display, ensure both are KT brand and share the same communication protocol. Also, check the appearance and brand of waterproof connectors (e.g., Julet) for proper line sequence compatibility.
• Argindarrik ez/Aldizkako argindarra: Check all cable connections for looseness or damage. Verify battery voltage is within the operating range (36V/48V) and above the low voltage babes atalasea.
• Motorrak ez du erantzuten: Ensure the motor's 9-pin connector is fully seated and undamaged. Check throttle and PAS connections.

If you encounter persistent issues or are unsure about troubleshooting steps, please contact the seller for assistance.
