4. Mode d'emploi
Once installed, operate the speed controller as follows:
- Mise sous tension : Connect the DC power supply. The red indicator light on the front panel should illuminate.
- Motor Direction Control: Use the three-position switch labeled 'RUN' to select the motor's direction or stop it.
- Placez le commutateur sur UP position for forward rotation.
- Placez le commutateur sur MILIEU position to stop the motor.
- Placez le commutateur sur VERS LE BAS position for reverse rotation.
- Réglage de la vitesse: Rotate the knob labeled 'SPEED CONTROL' to adjust the motor's speed.
- Turn the knob towards 'Low' for slower speeds.
- Turn the knob towards 'High' for faster speeds.
- Éteindre: To turn off the system, first set the direction switch to the 'STOP' (middle) position, then disconnect the main DC power supply.

6. Dépannage
If you encounter issues with your Heayzoki DC Motor Speed Controller, refer to the following table:
| Problème | Cause possible | Solution |
|---|---|---|
| Le moteur ne fonctionne pas | No power supply; Incorrect wiring; Faulty motor; Direction switch in 'STOP' position. | Vérifiez les connexions d'alimentation et le volume d'alimentationtage; Verify wiring against diagram; Test motor independently; Ensure direction switch is in 'Forward' or 'Reverse'. |
| Motor runs erratically or at incorrect speed | Loose wiring connections; Incompatible motor; Speed knob setting; Overload. | Check and secure all wiring; Ensure motor is compatible with controller specifications; Adjust speed knob; Reduce motor load. |
| Le contrôleur surchauffe | Excessive load on motor; Insufficient ventilation; Short circuit. | Reduce motor load; Ensure adequate airflow around the controller; Check for short circuits in wiring or motor. |
| Direction switch does not change motor direction | Faulty switch; Incorrect motor type (not reversible). | Verify switch functionality; Confirm motor is a reversible DC brush type. |
