Common faults of maglev blowers include:

1. Frequency converter communication abnormal, frequency converter abnormal or emergency stop: it may be the sensor and data communication abnormal, you need to contact the manufacturer.

2. Exceed the limit value of outlet air pressure: confirm whether the load (pipeline non-destructive, water level, etc.) has increased significantly.

3. If the pressure difference of the filter exceeds the limit value, clean or replace the suction filter.

4. Exceed the motor temperature limit value: take indoor sprinkling, forced ventilation and other cooling measures.

5. Exceeding the vibration level limit value: confirm the external vibration factors such as earthquakes or pipelines.

6. SURGE occurs: Confirm the performance curve and increase SV if running on the Surge line.

7. The maximum filter pressure difference of 95% warning: Clean or replace the suction filter.

8. Maximum suction temperature 95% warning: Maintain indoor air circulation.

9. Vibration sensor Max 95% warning: Contact the manufacturer technician.

10. Frequency converter temperature maximum 95% warning: Contact the manufacturer technician.

In order to ensure the normal operation of the maglev blower and extend its service life, it is recommended to perform regular maintenance and maintenance, including cleaning the filter, checking the sensor and cable connection, and regularly changing the lubricating oil. For details about maintenance methods, see the user manual or consult the manufacturer.
