4. Водич за инсталацију
Напомена: Installation of an electric scooter controller requires basic electrical knowledge and tools. If you are unsure, it is highly recommended to seek professional assistance to avoid damage or injury.
4.1 Пре него што почнете
- Ensure the scooter is powered off and the battery is disconnected.
- Gather necessary tools (e.g., screwdrivers, wire cutters, electrical tape, multimeter).
- Familiarize yourself with the existing wiring of your M4pro scooter.
4.2 Ожичење
The controller features multiple color-coded wires and connectors. Carefully match each connector from the new controller to the corresponding connector on your scooter. Refer to the image below for a visual guide to the various connections.

Слика 3: Детаљно view of the controller's wiring harness.
Common connections typically include:
- Каблови за напајање: Thick red and black wires (often with XT60 or similar connector) for battery connection.
- Фазне жице мотора: Three thick wires (e.g., yellow, green, blue) connecting to the motor.
- Жице Холовог сензора: A thinner multi-wire connector for motor position sensing.
- Throttle/Accelerator: Connector for the speed control.
- Полуге кочнице: Connectors for brake signal input (low level).
- Display/Dashboard: Connector for the scooter's display unit.
- Светла/сирена: Auxiliary power connections.
- Self-Learning Wires: Often two white wires that, when connected briefly, allow the controller to learn motor parameters.
Ensure all connections are secure and properly insulated. Incorrect wiring can cause damage to the controller, motor, or battery.
4.3 Провера после инсталације
- Двапут проверите све спојеве за чврстоћу и исправан поларитет.
- Поново повежите батерију.
- Perform a low-speed test in a safe, open area to ensure proper function of the motor, throttle, and brakes.
5. Упутство за употребу
Once correctly installed, the controller operates automatically to manage the electric scooter's motor. Its intelligent design ensures smooth acceleration and efficient power usage based on throttle input and other sensor data.
- Укључивање/искључивање: The controller powers on/off with the scooter's main power switch.
- убрзање: Use the scooter's throttle to control speed. The controller will translate your input into motor power.
- кочење: Activating the scooter's brake levers will send a low-level signal to the controller, which will cut power to the motor and engage braking.
- Лов Волtagе Заштита: The controller is designed to protect the battery by cutting power when the voltage drops below 39V, preventing over-discharge.
6. Одржавање
To ensure the longevity and optimal performance of your motor controller:
- Одржавајте суво: Protect the controller from water and excessive moisture. While the casing offers some protection, it is not fully waterproof.
- чистоћа: Periodically clean the exterior of the controller to prevent dust and dirt buildup, which can affect heat dissipation.
- Прегледајте везе: Regularly check all wiring connections for any signs of looseness, corrosion, or damage. Secure any loose connections.
- Избегавајте прегревање: Ensure the controller has adequate airflow. Avoid covering it or operating the scooter in conditions that lead to excessive heat buildup.
КСНУМКС. Решавање проблема
If you experience issues with your scooter after installing the new controller, consider the following:
| Проблем | Могући узрок | Решење |
|---|---|---|
| Скутер се не укључује. | Loose battery connection, faulty power switch, low battery voltage. | Check battery connections, ensure battery is charged, test power switch. |
| Мотор не реагује на гас. | Loose throttle connection, faulty throttle, incorrect motor phase/Hall sensor wiring. | Verify throttle and motor wiring. If applicable, perform self-learning procedure. |
| Motor runs intermittently or with unusual noise. | Loose motor phase wires, damaged Hall sensors, motor fault. | Check motor wiring. Consult a professional if the issue persists. |
| Brakes not engaging. | Loose brake lever connection, faulty brake lever. | Inspect brake lever wiring and functionality. |
| Контролер се прекомерно загрева. | Overload, poor ventilation, short circuit. | Reduce load, ensure proper airflow, check for short circuits in wiring. |
If troubleshooting steps do not resolve the issue, please contact customer support or a qualified technician.
8. Савети корисника
- Двострука провера компатибилности: Always confirm that the controller's voltage and current ratings match your scooter's motor and battery specifications before purchase and installation.
- Организујте ожичење: When replacing the controller, take photos of the original wiring setup. This can be a valuable reference during installation.
- Сигурна монтажа: Ensure the controller is securely mounted within the scooter's housing to prevent vibrations and physical damage.
- Почетни тест: After installation, lift the scooter's drive wheel off the ground and perform a gentle throttle test to confirm basic functionality before riding.
