Remedy: - Check the fan involved.
- If requir
ed, replace the fan.
- For communication errors, update the software or replace the power unit.
Note:
If the alarm has been withdrawn, this does not necessarily mean that the cause of the fault has been resolved. It is also
possible that the software switched o the fan, and therefore can no longer evaluate the feedback signal.
