Each warning state is 'latched' so if a problem is intermittent, the warning will stay present until acknowledged by
a reset. If the fault or warning status still exists at the time of reset, then the warning will continue to display its
warning status. If the condition has stopped, then the warning will fall to a lower priority warning until it is back
to OK.
