4. Installationsvejledning

Note: 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 Før du begynder

• 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 Ledningsforbindelser

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.

Common connections typically include:

• Strømkabler: Thick red and black wires (often with XT60 or similar connector) for battery connection.
• Motorfaseledninger: Tre tykke ledninger (f.eks. gul, grøn, blå) der forbindes til motoren.
• Hall-sensorledninger: A thinner multi-wire connector for motor position sensing.
• Gashåndtag/Speeder: Connector for the speed control.
• Bremsehåndtag: Connectors for brake signal input (low level).
• Display/Dashboard: Stik til scooterens displayenhed.
• Lights/Horn: Auxiliary power connections.
• Selvlærende ledninger: 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 Kontrol efter installation

• Dobbelttjek alle forbindelser for tæthed og korrekt polaritet.
• Tilslut batteriet igen.
• Perform a low-speed test in a safe, open area to ensure proper function of the motor, throttle, and brakes.

5. Betjeningsvejledning

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.

• Tænd/sluk: The controller powers on/off with the scooter's main power switch.
• Acceleration: Use the scooter's throttle to control speed. The controller will translate your input into motor power.
• Bremsning: 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.
• Lav voltage Beskyttelse: The controller is designed to protect the battery by cutting power when the voltage drops below 39V, preventing over-discharge.

6. Vedligeholdelse

To ensure the longevity and optimal performance of your motor controller:

• Hold tør: Beskyt controlleren mod vand og for meget fugt. Mens casing tilbyder en vis beskyttelse, den er ikke fuldt vandtæt.
• Renhed: Rengør controllerens yderside med jævne mellemrum for at forhindre ophobning af støv og snavs, som kan påvirke varmeafledningen.
• Undersøg forbindelser: Regularly check all wiring connections for any signs of looseness, corrosion, or damage. Secure any loose connections.
• Undgå overophedning: Ensure the controller has adequate airflow. Avoid covering it or operating the scooter in conditions that lead to excessive heat buildup.

7. Fejlfinding

If you experience issues with your scooter after installing the new controller, consider the following:

If troubleshooting steps do not resolve the issue, please contact customer support or a qualified technician.

8. Brugertips

• Dobbelttjek kompatibilitet: Always confirm that the controller's voltage and current ratings match your scooter's motor and battery specifications before purchase and installation.
• Organiser ledningsføring: When replacing the controller, take photos of the original wiring setup. This can be a valuable reference during installation.
• Sikker montering: Ensure the controller is securely mounted within the scooter's housing to prevent vibrations and physical damage.
• Indledende test: After installation, lift the scooter's drive wheel off the ground and perform a gentle throttle test to confirm basic functionality before riding.
