What indicates a minor fault in a controller?

A minor fault in a controller is often indicated by an alert notification. This notification serves as a warning to the operator or maintenance personnel that there is an issue that needs attention but does not require an immediate shutdown or extensive intervention. It allows for ongoing monitoring and ensures that the system can continue to operate while the fault is addressed, reflecting the underlying purpose of alert notifications—to provide information without disrupting overall functionality.

Alert notifications are crucial in operational environments where maintaining continuous workflow is essential, as they guide users in taking corrective actions within their controlled timelines. This proactive approach helps in minimizing downtime and enhances the reliability of the overall system.
