incident.

If the defect or incident cause disappears, then the alarm disappears.
A fault is displayed to warn the user about UPS failure or UPS mode change due to external
incident (Mains, load, temperature).
Fault display is: red led, continuous buzzer sound, fault message box.

then as long as the defect does not transfer to a permanent bypass mode or a stop: it is an
alarm/ otherwise it is a fault.
