4. Důležité bezpečnostní informace

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

• Zajistěte vstupní objtage 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.
• Install the controller in a well-ventilated area to prevent overheating.
• This device is not waterproof. Avoid exposure to moisture or liquids.
• Instalaci a zapojení by měl provádět pouze kvalifikovaný personál.

5. Nastavení a zapojení

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

1. Příkon: Connect your DC power supply to the terminals labeled 'POWER +' (positive) and 'POWER -' (negative). Ensure correct polarity.
2. Výkon motoru: Connect your DC motor to the terminals labeled 'MOTOR +' (positive) and 'MOTOR -' (negative).
3. Připojení potenciometru: 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. Návod k obsluze

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

1. Zapnutí: Apply DC power to the controller.
2. Vyberte směr: Use the three-position reversing switch to select the desired motor rotation direction:
   • Vpřed: Moves the switch to the 'I' position.
   • Vypnuto: Moves the switch to the 'O' (center) position to stop the motor.
   • Zvrátit: Moves the switch to the 'II' position.
3. Upravit rychlost: 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. Vypnout: To stop operation, first set the reversing switch to the 'Off' position, then disconnect the main DC power supply.
