The relay includes two user-programmable fault reports to enable capture of two types of trips (for example, trip from ther-
mal protection with the report configured to include temperatures, and short-circuit trip with the report configured to include
voltages and currents). Both reports feed the same report file queue.
The last record is available as individual data items via communications protocols.
•
PRE-FAULT 1 TRIGGER:
Specifies the FlexLogic operand to capture the pre-fault data. The rising edge of this oper-
and stores one cycle-old data for subsequent reporting. The element waits for the fault trigger to actually create a
record as long as the operand selected as
PRE-FAULT 1 TRIGGER
is “On”. If the operand remains “Off” for 1 second, the
element resets and no record is created.
•
FAULT 1 TRIGGER:
Specifies the FlexLogic operand to capture the fault data. The rising edge of this operand stores
the data as fault data and results in a new report. The trigger (not the pre-fault trigger) controls the date and time of the
report.
•
FAULT REPORT 1 #1
to
FAULT REPORT 1 #32:
These settings specify an actual value such as voltage or
current magnitude, true RMS, phase angle, frequency, temperature, etc., to be stored should the report be cre-
ated. Up to 32 channels can be configured. Two reports are configurable to cope with variety of trip conditions and
items of interest.

PRODUCT SETUP
OSCILLOGRAPHY
Oscillography records contain waveforms captured at the sampling rate as well as other relay data at the point of trigger.
Oscillography records are triggered by a programmable FlexLogic operand. Multiple oscillography records can be captured
simultaneously.
The
NUMBER OF RECORDS
is selectable, but the number of cycles captured in a single record varies considerably based on
other factors, such as sample rate and the number of operational modules. There is a fixed amount of data storage for
oscillography; the more data captured, the less the number of cycles captured per record. See the

ple configurations with corresponding cycles/record. The minimum number of oscillographic records is three.
