Vigtige ledningsføringspunkter:

• Strømtilslutning: Connect the main battery positive (B+) and negative (B-) terminals to the corresponding controller inputs.
• Motorfaseledninger: Connect the three phase wires from the motor to the controller's phase outputs.
• Hall-sensorledninger: Connect the motor's Hall sensor wires to the controller's Hall sensor input.
• Gashåndtag: Connect the throttle (0-5V) signal wire, positive, and negative wires.
• Bremser: Connect low brake (0V) and high brake (12V) wires as per your system.
• Tænding: Connect the ignition wire to the vehicle's ignition switch.
• Learning Wires: Two learning wires are provided to assist in motor phase angle detection. Connect them temporarily during initial setup to allow the controller to learn the motor's phase angle, then disconnect.
• Andre funktioner: Connect wires for reverse, one-LIN/Hall speed sensor, program port, three-speed switch, sport mode, parking, anti-theft, and regen charge as required by your setup.

6. Vedligeholdelse

The VOTOL EM50-4 controller is designed for durability and requires minimal maintenance. However, adhering to the following guidelines can extend its lifespan:

• Regelmæssig inspektion: Kontrollér regelmæssigt alle ledningsforbindelser for tæthed og tegn på slid eller korrosion.
• Renhed: Hold controlleren fri for støv, snavs og fugt. Brug en tør, blød klud til rengøring. Undgå at bruge skrappe kemikalier eller opløsningsmidler.
• Ventilation: Ensure the controller's mounting location allows for adequate airflow around the heat sink to prevent overheating.
• Undgå overbelastning: Operate the controller within its specified voltage og aktuelle grænser for at forhindre skade.

7. Fejlfinding

If you encounter issues with your EM50-4 controller, consider the following common troubleshooting steps:

• Ingen strøm: Check battery connections, ignition switch, and main power fuses. Ensure the battery voltage er inden for regulatorens driftsområde (48V-72V).
• Motoren reagerer ikke: Verify throttle connections and functionality. Check motor phase wire connections and Hall sensor connections. Ensure the motor's Hall sensors are functioning correctly.
• Uregelmæssig drift: Inspect all wiring for loose connections or shorts. Ensure no water or moisture has entered the controller. If recently programmed, revert to a known working configuration or default settings.
• Overophedning: Check for obstructions around the controller's heat sink. Reduce continuous high-power operation if possible. Ensure the motor is not drawing excessive current.
• Programmeringsproblemer: Ensure the correct USB cable is used and drivers are installed on your PC. Verify the programming software is compatible with your controller model.

For persistent issues, consult a qualified technician or contact the product support for assistance.
