4.5 Alarm codes
Using a sophisticated self-diagnosis system, the UPS is able to check its
own status and any anomalies and/or faults which may occur during
normal operation and display them on the display panel. If there is a
problem, the UPS signals the event by showing the code and the type of
active alarm on the display.
Alarms
“Minor” problems which reduce performance or prevent certain functions
from being used.
