TATISTICS

All alarms and information events are captured and kept in an alarm history file in 
the PathBuilder S330/S310. 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.

To view and print an alarm history, follow these steps:

1 From the Main menu, select [3] Fault Management to display the Fault 

2 Select [3] Display History Alarms to view the alarm history. Figure 135 shows a 

sample alarm history.

Figure 135   Sample Alarm History Display

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 or 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.

After you have printed the alarm history, you should clear the alarms so that they 
will no longer take up space in the alarm history file. To do this, follow these steps:

1 Return to the Fault Management menu.

2 Select [4] Clear History Alarms.

3 Enter y in response to the confirmation prompt to clear the history alarms.
