5. Setup and Installation
Follow these steps for proper installation and wiring:
- Mounting: Secure the controller using the designated mounting holes. Refer to the mounting size in the specifications.
- Power Connection: Connect your DC power supply to the terminals labeled +POWER-. Ensure correct polarity: positive (+) to +POWER and negative (-) to -POWER. The input voltage must be between 12V and 60V DC.
- Motor Connection: Connect your DC brush motor to the terminals labeled +MOTOR-. Ensure correct polarity for desired initial rotation direction. If the motor rotates in the opposite direction, reverse the motor connections.
- Verify Connections: Double-check all wiring connections for security and correct polarity before applying power. Loose connections can cause damage or malfunction.

6. Operating Instructions
Once the controller is properly installed and wired, follow these steps to operate your DC motor:
- Apply Power: Turn on your DC power supply. The controller is now ready for operation.
- Set Rotation Direction: Use the three-position switch located at the bottom of the front panel to select the desired motor direction:
- UP position: Forward rotation.
- MIDDLE position: Stop.
- DOWN position: Reverse rotation.
- Adjust Speed: Rotate the central knob labeled 'SPEED CONTROL' to adjust the motor's speed. Turn the knob towards 'High' for increased speed and towards 'Low' for decreased speed. The markings (10, 20, 30, etc.) indicate relative speed levels.
- Stopping the Motor: To stop the motor, move the three-position switch to the middle position.

7. Maintenance
The Ejoyous DC Motor Speed Controller is designed for durability and requires minimal maintenance. To ensure optimal performance and longevity:
- Keep the controller clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Ensure the operating environment is dry and free from excessive moisture or corrosive substances.
- Periodically check all wiring connections to ensure they remain tight and secure.
- Do not attempt to open the casing or modify the internal circuitry, as this will void any potential warranty and may cause damage.
8. Troubleshooting
If you encounter issues with your motor speed controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not run | No power supply; Incorrect wiring; Faulty motor; Direction switch in 'Stop' position. | Check power supply and connections; Verify wiring polarity; Test motor separately; Move direction switch to 'Forward' or 'Reverse'. |
| Motor runs at full speed, cannot be adjusted | Speed control knob faulty; Internal circuit issue. | Ensure knob is not stuck; Contact support if issue persists. |
| Motor runs in wrong direction | Incorrect motor wiring polarity. | Reverse the motor connections (+MOTOR-). |
| Controller overheats | Overload; Insufficient ventilation; Short circuit. | Reduce motor load; Ensure adequate airflow around the controller; Check for short circuits in wiring. |
If the problem persists after attempting these solutions, please contact customer support.
