The 'Active Warnings' Menu; The 'Number Of Errors' Menu - ABB PQFM Instruction Manual

A fault is considered critical if after occurrence, it cannot be successfully
automatically cleared by the system within a reasonable time. The time frame
considered depends on the error type.
In practice the word 'Critical' will appear in the 'Event logging' window if the
system has detected a critical error. The user can then backtrack in the logging
window to see which errors were already present in the previous events, to know
which is/are the critical error(s).
