KT D12L PAS Magnetic Point Sensor Instruction Manual

1. Introduction

The KT D12L PAS (Pedal Assist System) Magnetic Point Sensor is designed to enhance your e-bike experience by providing pedal assistance. This sensor detects pedal rotation and signals the e-bike controller to activate the motor, offering a smoother and more intuitive ride. It is available with either an SM plug (standard) or a waterproof plug for various bicycle refit applications.

This manual provides detailed instructions for the proper installation, operation, and maintenance of your KT D12L PAS sensor.

2. Product Components

Before installation, please ensure all components are present:

• KT D12L Sensor Unit (with attached cable and plug)
• Magnetic Disc (split type for easy installation)
• Zip Ties (for securing the sensor cable)

3. Installation Guide

Follow these steps for proper installation of the PAS sensor:

1. 3.1. Magnetic Disc Installation

   The magnetic disc is a split type, allowing for easy installation without removing the crank. Carefully separate the two halves of the magnetic disc and place it onto the bicycle's crank axle, ensuring the magnets face the direction where the sensor will be mounted. Secure the two halves together.

2. 3.2. Sensor Unit Mounting

   Mount the sensor unit on the bicycle frame, typically on the left side, adjacent to the magnetic disc on the crank arm. Ensure the sensor is positioned to detect the passing magnets as the pedals rotate. The sensor should be installed on the left side of the bicycle.

   

3. 3.3. Gap Adjustment

   Crucially, ensure there is an optimal gap of approximately 3mm between the sensor unit and the magnetic disc. This gap is vital for accurate detection of pedal rotation. Adjust the sensor's position as needed to achieve this distance.

4. 3.4. Electrical Connection

   Connect the sensor's plug to the corresponding port on your e-bike controller. The KT D12L sensor comes in two plug types:

   • SM Plug (Standard): Features a three-core ordinary connector.
   • Waterproof Plug: Features a three-core waterproof connector.

   

   

   Ensure the connection is secure and the correct plug type is used for your system.

5. 3.5. Cable Management

   Use the provided zip ties to neatly secure the sensor cable along the bicycle frame, preventing it from interfering with moving parts or getting damaged.

4. Operation

The KT D12L PAS sensor operates by detecting the rotation of the magnetic disc attached to your bicycle's crank. When you begin pedaling, the magnets pass by the sensor, which then sends a signal to your e-bike controller. The controller interprets this signal and activates the motor to provide pedal assistance, based on your e-bike's settings and assist level.

The sensor is designed to work within a voltage range of 12V to 72V, making it compatible with a wide range of e-bike systems.

5. Maintenance

To ensure the longevity and optimal performance of your KT D12L PAS sensor, consider the following maintenance tips:

• Keep Clean: Regularly wipe down the sensor and magnetic disc to remove dirt, dust, and debris that could interfere with detection.
• Check Connections: Periodically inspect the electrical connection to the controller to ensure it is secure and free from corrosion or damage.
• Inspect for Damage: Check the sensor unit, magnetic disc, and cable for any signs of physical damage, cracks, or fraying. Replace damaged components immediately.
• Maintain Gap: Ensure the 3mm gap between the sensor and the magnetic disc is maintained. If it shifts, readjust it to prevent inconsistent pedal assist.

6. Troubleshooting

If you experience issues with your PAS sensor, try the following troubleshooting steps:

• No Pedal Assist: If the motor does not engage when pedaling, check the electrical connection of the sensor to the controller. Ensure the sensor is correctly aligned with the magnetic disc and the 3mm gap is maintained.
• Intermittent Assist: Inconsistent pedal assist can often be resolved by cleaning the sensor and magnetic disc, ensuring no debris is obstructing the signal. Also, re-verify the 3mm gap and the security of the electrical connection.
• Sensor Light (if applicable): Some sensors have an indicator light. If yours does, observe its behavior. A steady light when pedaling usually indicates proper function, while no light or a flickering light might suggest an issue.
• Check Controller Settings: Ensure your e-bike controller's settings are configured to recognize and utilize a PAS sensor.

If problems persist after these steps, it may indicate a faulty sensor or controller. Contact customer support for further assistance.
