3.4.8 Viewing causes of alarm
-- Menu #7 "Alarm Cause" --
Menu #7 "Alarm Cause" in Programming mode shows the causes of the past four alarms that triggered protective functions, as an
alarm code. It also shows the cause of each alarm.
Basic configuration of screens
Figure 3.17 shows the LCD screen transition for Menu #7 "Alarm Cause."
A hierarchy exists among those screens that are shifted in the order of "menu screen," "list of alarms," and "alarm cause screens."
On the "alarm cause screen" of the desired alarm code, you can view the cause of the alarm.
The list of alarms is the same as that for Menu #6 "Alarm Information."
