5. Setup and Installation
Follow these steps to correctly install and wire your motor speed controller.
Wiring Instructions:
Figure 5.1: Wiring diagram illustrating the connection points for power input and motor output.
- Power Input: Connect your DC power supply to the terminals labeled 'Input positive 6-60V' (positive) and 'negative power supply' (negative). Ensure the voltage is within the 6V-60V DC range.
- Motor Output: Connect your DC motor to the terminals labeled 'motor positive' (positive) and 'motor negative' (negative).
- Secure Connections: Tighten all screw terminals to ensure a secure and stable connection. Loose connections can cause overheating or malfunction.
Always double-check your wiring before applying power to prevent damage to the controller or motor.

6. Operating Instructions
Once the controller is correctly wired and powered on, you can begin operating your DC motor.
- Power On: Apply power to the controller. The LED display will illuminate, showing the current speed percentage.
- Start/Stop Function: The rotary knob also functions as a start/stop switch. A short press of the knob will start or stop the motor.
- Speed Adjustment: Rotate the knob clockwise to increase the motor speed and counter-clockwise to decrease it. The LED display will show the speed as a percentage (0-100%).
- Setting Mode (Advanced): A long press of the rotary knob will enter the setting mode for advanced parameters. Refer to specific product documentation or manufacturer support for details on advanced settings if needed.

7. Maintenance
To ensure the longevity and optimal performance of your Aideepen PWM DC Motor Speed Controller, follow these maintenance guidelines:
- Cleaning: Periodically clean the exterior of the controller with a soft, dry cloth. Do not use liquid cleaners or solvents.
- Inspection: Regularly inspect the wiring connections for any signs of looseness, corrosion, or damage. Tighten connections as needed.
- Ventilation: Ensure that the ventilation openings are not obstructed to prevent overheating.
- Storage: If storing the controller for an extended period, keep it in a dry, dust-free environment.
8. Troubleshooting
If you encounter issues with your motor speed controller, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not start | No power supply; Incorrect wiring; Motor in stop mode; Faulty motor. | Check power connections and supply voltage; Verify wiring according to Figure 5.1; Short press the rotary knob to start the motor; Test motor independently. |
| Motor speed cannot be adjusted | Rotary knob malfunction; Controller fault. | Ensure the knob rotates freely; If issue persists, contact support. |
| LED display is off or flickering | No power; Low input voltage; Loose connection. | Check power supply; Ensure input voltage is within 6-60V; Inspect and tighten all wiring connections. |
| Controller overheats | Overload; Poor ventilation; Short circuit. | Reduce motor load; Ensure adequate airflow around the controller; Check for short circuits in wiring. |
