Remedy: - Check the heat sink fan and replace if necessary.
- For communication errors, updat
e the software or replace the power unit.
Note:
- If the fault can be acknowledged, 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.
