Remedy:
- Check the heat sink fan and replace if necessary.
- For communication errors, update 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 off the fan, and therefore can no longer evaluate the feedback signal.
