FAULT REPORTING
Fault Reporting Expressions and Settings
The fault reporting function records and reports information about faults that have been detected by the
relay. The BE1-700 provides many fault reporting features. These features include Fault Summary
Reports, Sequence of Events Recorder Reports, Oscillographic Records, and Targets.
Logic expressions are used to define the three conditions for fault reporting. These conditions are Trip,
Pickup, and Logic trigger. Figure 6-6 and Table 6-8 illustrate how each of these logic expressions is used
by the various relay functions. Note that even though BESTlogic expressions are used to define these
conditions, these expressions are not included here. Section 7, BESTlogic Programmable Logic, provides
information about using BESTlogic to program the relay.
Trip
Trip expressions are used by the fault reporting function to start logging targets for an event and to record
fault current magnitudes at the time of trip. The trip expression is used to illuminate the Trip LED on the
HMI. The Trip LED will turn on and remain on as long as the trip expression is true. The Trip LED will
remain on (or “sealed-in”) after the trip expression becomes false if targets are associated with the trip.
The breaker monitoring function uses the trip expression to start counting the breaker operate time.
Pickup
Pickup expressions are used by the fault reporting function to time-stamp the fault summary record, time
the length of the fault from pickup to dropout (fault clearing time), and to control the recording of
oscillographic data. The pickup expression is used to flash, on and off, the Trip LED on the HMI. The Trip
LED will continue to flash on and off as long as the pickup expression is true and the trip expression is not
true. A pickup expression is also used by the setting group selection function to prevent a setting group
change during a fault.
Logic
Logic trigger expressions allow the fault reporting function to be triggered even though the relay in not
picked up. A logic trigger expression provides an input to the fault reporting function much as the pickup
expression does. This logic expression is not used by the setting group selection or the HMI.
Fault Reporting Trigger Settings
Fault reporting trigger settings are made from the BESTlogic Function Element screen in BESTCOMS.

function. To open the BESTlogic Function Element screen for Fault Recording, select Reporting and
