Check configuration, check I/O required for configuration is
present and correct any illegal use of the invalid signal by
changing configuration or fitting additional option cards.

Ensure process is stable and repeat autotune.
If problem persists tune the loop manually.
Check process for issues that may have caused a large
change in its dynamics, for example, a blocked valve.
