ChongXiao Universal Electric Scooter/E-Bike Throttle User Manual

1. Product Overview

The ChongXiao Universal Electric Scooter/E-Bike Throttle is designed for speed control and features an integrated display for speed and mileage. It is compatible with most brushless controllers and supports a wide range of voltages including 36V, 48V, 60V, and 72V, which can be configured by the user.

This image shows the complete throttle assembly, including the integrated display, key ignition, and textured grip. The display shows current speed and mileage, and the key provides security for the electric scooter or e-bike.

2. Setup and Installation

2.1 Physical Installation

• The throttle line measures approximately 150cm in length.
• The mounting hole diameter for the throttle is 22mm. Ensure your handlebar or mounting point matches this specification.

This image displays the throttle unit with its integrated display and key ignition, along with the connected wiring harness and a separate matching left-hand grip. The wires are bundled for organization.

2.2 Wiring Connections

Connect the throttle to your controller using the following wiring scheme. It is crucial to match colors correctly. If the throttle interface does not match your controller's interface, you may need to cut off the existing interface and connect the wires directly. This requires DIY expertise.

This close-up image shows the three main wiring connections from the throttle: 1. Phase Speed (connects to controller's pointer meter or Hall wires), 2. Key Lock (connects to controller's key lock or electric door lock), and 3. Throttle (connects to controller's throttle wires). Ensure color-to-color matching for proper function.

• Phase Speed: Connect to the controller's pointer meter or Hall wires.
• Key Lock: Connect to the controller's key lock (also known as electric lock or electric door lock).
• Throttle: Connect to the controller's throttle wires. Ensure color-to-color connection.

3. Operating Instructions

3.1 Initial Voltage Setting

Before first use, or if the voltage display is incorrect, set the appropriate voltage for your system:

1. Press and hold the M-key.
2. While holding the M-key, turn the ignition key to start the machine.
3. Continue to long press the M-key until the voltage parameter on the display flashes.
4. Short press the M-key repeatedly to cycle through the available voltage options (36V, 48V, 60V, 72V) until your desired voltage is displayed.
5. Long press the M-key again until 'P02' flashes.
6. Shut down the machine (turn off the ignition key) to save the parameter settings.

This image shows the throttle's display screen in operation, indicating a speed of 71.6 km/h and a mileage of 2.2 km. The 'M' button for mode/settings is visible next to the display.

3.2 LCD Instrument Parameter Settings

To access and adjust advanced parameters:

1. Press and hold the M-key to turn on the power and enter the parameter setting mode.
2. Navigate Parameters: Short press the M-key to quickly switch between 'P' characters (e.g., P01, P02, etc.) in descending order.
3. Adjust Parameter Value: Long press the M-key for more than 3 seconds. The lower row of numbers will flash. Short press the M-key to change the parameter value.
4. Save Settings: Hold the M-key for 5 seconds to save the current parameters.

Parameter Codes:

• P01: Voltage setting. Can be set to 36V, 48V, 60V, 72V. Default: 48V.
• P02: Range 10 to 150. Default: 100.
• P03: Range 90 to 130. Default: 100.
• P04: Speed measurement mode. 0001 = Phase speed testing, 0002 = Hall speed testing.
• P05: Wheel diameter setting. Options: 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 29 inches. Default: 14 inches.
• P06: Number of magnetic steel. Range 1 to 99. Default: 30.
