Working with History
Alarms
The PathBuilder S600 captures all alarms and information events and keeps them
in an alarm history file. This file can hold up to 300 events; it fills on a
first-in/first-out basis. We recommend that you routinely view the alarm history file
before events are lost. We also recommend that you print the file for comparison
with previous history files and entry into your maintenance log.
Viewing and Printing History Alarms
To view and print an alarm history, follow these steps:
1
From the Main menu, select
[3] Fault Management
to display the Fault
Management menu shown earlier in Figure 145.
2
Select
[3] Display History Alarms
to view the alarm history. Figure 147 shows a
Display History Alarm screen.

.Display History Alarm Screen
If the history file cannot be displayed on one page, the Display History Alarm
screen will include a prompt to press [N] for the next page and press [P] for the
previous page.
3
Use the print screen or other printing feature of your NMS station to print out
each page of the history file.
4
Compare the printouts to your most previous records to see if there are any
obvious trends, such as more frequent alarms of a certain type, which might
require troubleshooting.
