4. Informazioni importanti sulla sicurezza

WARNING: Electrical shock hazard. Always disconnect power before making any connections or performing maintenance.

• Assicurare il volume di inputtage 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.
• Installare il controller in un'area ben ventilata per evitare il surriscaldamento.
• This device is not waterproof. Avoid exposure to moisture or liquids.
• L'installazione e il cablaggio devono essere eseguiti solo da personale qualificato.

5. Configurazione e cablaggio

Before beginning installation, ensure all power sources are disconnected. Refer to the wiring diagram below for proper connections.

1. Potenza in ingresso: Connect your DC power supply to the terminals labeled 'POWER +' (positive) and 'POWER -' (negative). Ensure correct polarity.
2. Uscita motore: Connect your DC motor to the terminals labeled 'MOTOR +' (positive) and 'MOTOR -' (negative).
3. Collegamento del potenziometro: The speed control potentiometer is pre-wired. Connect its cable to the corresponding port on the controller board.
4. Reversing Switch Connection: The forward/off/reverse switch is pre-wired. Connect its cable to the corresponding port on the controller board.

6. Istruzioni per l'uso

Once the controller is properly wired and secured, you can begin operation.

1. Accensione: Apply DC power to the controller.
2. Seleziona la direzione: Use the three-position reversing switch to select the desired motor rotation direction:
   • Inoltrare: Moves the switch to the 'I' position.
   • Spento: Moves the switch to the 'O' (center) position to stop the motor.
   • Inversione: Moves the switch to the 'II' position.
3. Regola la velocità: 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%.
4. Spegni: To stop operation, first set the reversing switch to the 'Off' position, then disconnect the main DC power supply.

7. Manutenzione e cura

To ensure the longevity and optimal performance of your Walfront DC PWM Motor Controller, follow these maintenance guidelines:

• Pulizia: 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.
• Ispezione: Controllare regolarmente tutti i collegamenti elettrici per assicurarsi che siano sicuri e privi di corrosione o danni.
• Ambiente: Operate the controller in a clean, dry, and well-ventilated environment. Avoid extreme temperatures and humidity.
• Magazzinaggio: If storing the controller for an extended period, disconnect it from all power sources and store it in a cool, dry place.
