7. Maintenance
Regular maintenance helps ensure the longevity and reliable operation of your soft starter. Always disconnect power before performing any maintenance.
- Keep the soft starter clean and free from dust and debris.
- Ensure proper ventilation to prevent overheating.
- Periodically check all electrical connections for tightness.
- Inspect wiring for any signs of wear or damage.
8. Troubleshooting
The soft starter is equipped with protective functions that display error codes on the LCD panel in case of abnormal conditions. Refer to the parameter setting and fault output video (Video 6.1) for detailed information on fault codes and their meanings.
- Input Open Phase Protection: The soft starter will detect if an input phase is missing.
- Output Open Phase Protection: Detects if an output phase to the motor is disconnected.
- Running Overload Protection: Protects the motor from excessive current draw during operation.
- Unbalanced Three-Phase Protection: Monitors for imbalances in the three-phase supply.
If a fault occurs, the fault output port (terminals 5 and 6) will close, and a fault code will be displayed on the LCD. After resolving the issue, press the reset button to clear the fault and resume normal operation.
