Qinlorgo DC Motor Speed Controller Instruction Manual

1. Einleitung

This manual provides detailed instructions for the installation, operation, and maintenance of your Qinlorgo DC Motor Speed Controller. This device is designed to control the speed and direction of brushed DC motors within the specified voltage and current ranges. Please read this manual thoroughly before use to ensure proper function and safety.

2. Produktmerkmale

• Langlebige Konstruktion: Manufactured with a high-quality circuit board for extended service life.
• Stabil und zuverlässig: Features convenient screw terminals for secure and quick wire connections.
• Direction Reversal: Capable of changing the rotation direction of the connected motor.
• Einfache Bedienung: Simple knob rotation adjusts the output to control the brushed motor's revolving speed.
• Kompaktes Design: Elegant and easy-to-use form factor.

3. Sicherheitshinweise und wichtige Hinweise

• Stromversorgung: Connect only to a DC power supply. NICHT connect directly to household 220V alternating current (AC).
• Motor Connection Required: This is a motor speed controller, not a power module. A motor MUSS be connected for the speed control function to operate. Multimeter output readings will not change without a connected motor.
• Motortyp: This governor is designed exclusively for DC brushed motors. Es ist NICHT suitable for DC brushless motors.
• Funktionalität: This device cannot be used as a voltage regulator or stabilizer. Its sole purpose is motor speed control.
• Derzeitige Begrenzung: Die maximale Stromstärke von 3 A darf nicht überschritten werden.

5. Aufbau und Verkabelung

The controller features clearly labeled screw terminals for input power and motor output. Ensure all connections are secure before applying power.

1. Terminals identifizieren: Locate the 'IN' terminals for power input and 'OUT' terminals for motor connection.
2. Stromeingang anschließen: Connect your DC power supply (6V, 12V, or 24V) to the 'IN' terminals. Observe polarity: positive to '+' and negative to '-'.
3. Motor anschließen: Connect your brushed DC motor to the 'OUT' terminals. The polarity here will determine the initial direction of rotation.
4. Connect Reversing Switch: The included switch is pre-wired to allow for motor direction reversal. Connect its wires as shown in the diagram.

6. Bedienungsanleitung

Once the controller is correctly wired and powered, you can begin operation:

1. Einschalten: Ensure your DC power supply is active.
2. Geschwindigkeit anpassen: Rotate the potentiometer knob (the silver knob on the board) clockwise to increase motor speed and counter-clockwise to decrease motor speed.
3. Die Richtung ändern: Use the attached black switch to reverse the motor's direction of rotation. The switch typically has three positions: one for forward, one for reverse, and a center-off position.

7. Wartung

The Qinlorgo DC Motor Speed Controller is designed for reliable operation with minimal maintenance. Follow these general guidelines:

• Sauber halten: Periodically clean the controller board to prevent dust and debris accumulation, which can affect performance. Use a soft, dry brush or compressed air.
• Feuchtigkeit vermeiden: Protect the device from water, humidity, and corrosive environments.
• Verbindungen prüfen: Regularly check all wire connections to ensure they remain tight and secure.
• Betriebsumgebung: Operate the controller within its specified temperature and humidity ranges to ensure optimal lifespan.

8. Fehlerbehebung

If you encounter issues with your motor speed controller, refer to the following troubleshooting steps:

• Motor dreht sich nicht:
  • Verify that the DC power supply is connected correctly and providing the correct voltage (6 V, 12 V oder 24 V).
  • Ensure the motor is properly connected to the 'OUT' terminals.
  • Confirm that the motor is a brushed DC motor. This controller is not compatible with brushless motors.
  • Check the reversing switch position; it might be in the 'off' or neutral position.
• Speed Not Changing:
  • Ensure a motor is connected. The controller requires a load (motor) to regulate speed effectively.
  • Rotate the potentiometer knob through its full range to check for responsiveness.
• Intermittierender Betrieb:
  • Check all wire connections for looseness or poor contact.
  • Ensure the current draw of your motor does not exceed the 3A maximum rating of the controller. Overloading can cause intermittent operation or damage.
