How can an auto-fail be reset?

Resetting an auto-fail condition after a fault is corrected is accomplished at the AMCOP (Automatic Control and Monitoring of Protection) Selector Switch. This switch is specifically designed to allow the operator to reset protective devices after a fault condition has been identified and addressed. It ensures that the system can be safely returned to normal operation without requiring physical intervention or replacement of components.

The purpose of this procedure is to enable a systematic and safe restoration of functionality, as the system needs to confirm that the conditions that caused the auto-fail are resolved before reactivation. This is a crucial safety step in electrical systems to prevent potential hazards such as equipment damage or safety risks to personnel.

In this context, options involving replacing breakers or turning off power to the system do not directly lead to a reset of the auto-fail condition. They may disrupt operations without confirming the resolution of fault conditions. Using the manual override switch is also not standard practice for resetting an auto-fail, as it does not ensure that the underlying issues have been properly addressed before heading back to operational status.
