4. Informació important de seguretat
WARNING: Electrical shock hazard. Always disconnect power before making any connections or performing maintenance.
- Assegureu-vos que l'entrada voltage is within the specified range (DC 10V to 50V). Exceeding this range can damage the device.
- Do not exceed the maximum continuous current of 40A.
- Properly insulate all connections to prevent short circuits.
- Instal·leu el controlador en una zona ben ventilada per evitar el sobreescalfament.
- This device is not waterproof. Avoid exposure to moisture or liquids.
- Només personal qualificat ha de realitzar la instal·lació i el cablejat.
5. Configuració i cablejat
Before beginning installation, ensure all power sources are disconnected. Refer to the wiring diagram below for proper connections.
- Entrada d'alimentació: Connect your DC power supply to the terminals labeled 'POWER +' (positive) and 'POWER -' (negative). Ensure correct polarity.
- Sortida del motor: Connect your DC motor to the terminals labeled 'MOTOR +' (positive) and 'MOTOR -' (negative).
- Connexió del potenciòmetre: The speed control potentiometer is pre-wired. Connect its cable to the corresponding port on the controller board.
- Reversing Switch Connection: The forward/off/reverse switch is pre-wired. Connect its cable to the corresponding port on the controller board.

6. Instruccions de funcionament
Once the controller is properly wired and secured, you can begin operation.
- Encès: Apply DC power to the controller.
- Selecciona la direcció: Use the three-position reversing switch to select the desired motor rotation direction:
- Endavant: Moves the switch to the 'I' position.
- Apagat: Moves the switch to the 'O' (center) position to stop the motor.
- Revers: Moves the switch to the 'II' position.
- Ajustar velocitat: Rotate the potentiometer knob to adjust the motor speed. Turning the knob clockwise will increase the speed, while turning it counter-clockwise will decrease the speed. The speed can be adjusted from 0% to 100%.
- Apagar: To stop operation, first set the reversing switch to the 'Off' position, then disconnect the main DC power supply.

7. Manteniment i cura
To ensure the longevity and optimal performance of your Walfront DC PWM Motor Controller, follow these maintenance guidelines:
- Neteja: Periodically clean the exterior of the controller with a dry, soft cloth. Do not use liquid cleaners or solvents. Ensure the ventilation holes are free from dust and debris.
- Inspecció: Inspeccioneu regularment totes les connexions del cablejat per assegurar-vos que estiguin ben fixades i que no presentin corrosió ni danys.
- Medi ambient: Operate the controller in a clean, dry, and well-ventilated environment. Avoid extreme temperatures and humidity.
- Emmagatzematge: If storing the controller for an extended period, disconnect it from all power sources and store it in a cool, dry place.
8. Solució De Problemes
If you encounter issues with your motor controller, refer to the following common problems and solutions:
| Problema | Causa possible | Solució |
|---|---|---|
| El motor no funciona | Sense font d'alimentació Cablejat incorrecte Reversing switch in 'Off' position Potentiometer set to 0% speed | Check power connections and source Verify all wiring according to Section 5 Move reversing switch to 'Forward' or 'Reverse' Rotate potentiometer clockwise to increase speed |
| Motor runs intermittently or erratically | Connexions soltes Sobrecàrrega Motor defectuós | Comproveu i fixeu totes les connexions del cablejat Reduce load on the motor; ensure current does not exceed 40A continuous Test motor independently to confirm functionality |
| Speed control is not responsive | Potentiometer not connected properly Damaged potentiometer | Ensure potentiometer cable is securely connected If issue persists, the potentiometer may need replacement |
| Motor does not reverse direction | Reversing switch not functioning Incorrect motor wiring for reversal | Check reversing switch connection and functionality Verify motor is a reversible DC motor and wired correctly for reversal |
