4. Vigtige sikkerhedsoplysninger

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

• Sørg for, at input 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.
• Installer styreenheden i et godt ventileret område for at forhindre overophedning.
• This device is not waterproof. Avoid exposure to moisture or liquids.
• Kun kvalificeret personale bør udføre installation og ledningsføring.

5. Opsætning og ledningsføring

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

1. Strømindgang: Connect your DC power supply to the terminals labeled 'POWER +' (positive) and 'POWER -' (negative). Ensure correct polarity.
2. Motorudgang: Connect your DC motor to the terminals labeled 'MOTOR +' (positive) and 'MOTOR -' (negative).
3. Potentiometerforbindelse: 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. Betjeningsvejledning

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

1. Tænd: Apply DC power to the controller.
2. Vælg retning: Use the three-position reversing switch to select the desired motor rotation direction:
   • Frem: Moves the switch to the 'I' position.
   • Slukket: Moves the switch to the 'O' (center) position to stop the motor.
   • Bagside: Moves the switch to the 'II' position.
3. Juster hastighed: 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. Sluk: To stop operation, first set the reversing switch to the 'Off' position, then disconnect the main DC power supply.

7. Vedligeholdelse og pleje

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

• Rensning: 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.
• Inspektion: Kontrollér regelmæssigt alle ledningsforbindelser for at sikre, at de er fastgjorte og fri for korrosion eller beskadigelse.
• Miljø: Operate the controller in a clean, dry, and well-ventilated environment. Avoid extreme temperatures and humidity.
• Opbevaring: If storing the controller for an extended period, disconnect it from all power sources and store it in a cool, dry place.
