BE1-CDS220 Reporting and Alarm Functions 6-33
Fault Summary Reports
The BE1-CDS220 records information about faults and creates fault summary reports. A maximum of 12
fault summary reports are stored in the relay. The two most recent reports are stored in nonvolatile
memory. When a new fault summary report is generated, the relay discards the oldest of the 12 events
and replaces it with a new one. Each fault summary report is assigned a sequential number (from 1 to
255) by the relay. After event number 255 has been assigned, the numbering starts over at 1.
If the PICKUP or LOGIC trigger expressions stay TRUE for longer than 60 seconds, an alarm bit (FAULT
RECORD TIMEOUT) in the programmable alarm function will be set. In this situation, the fault reporting
functions (including targets) will not operate again until the PICKUP and LOGIC trigger expressions return
to a false state to enable another trigger.
BESTCOMS Fault Summary Report
To view fault reports using BESTCOMS, select Oscillography Download from the Reports pull-down
menu. A screen such as the one shown in Figure 6-20 will appear.
Figure 6-20. View/Download Relay Fault Files Screen
From this screen, you can View Fault Details or View Fault Sequence of Events by selecting your choice
at the top of the screen and then highlighting the fault to be displayed. In Figure 6-20, fault 004 is
highlighted.
The Trigger button allows for a fault to be manually triggered. This can also be done using the SG-
TRIGGER ASCII command.
The Refresh button is used to refresh the list of faults. The Download button will download the selected
fault, storing it on the selected drive as either a binary or ASCII file, selected beneath the button.
Fault Summary Report Example
A fault summary report collects several items of information about a fault that can aid in determining why
a fault occurred without having to sort through all of the detailed information available. The following
example illustrates a typical fault summary report. Call-outs shown in the report are references to the
legend of Table 6-11.
