PRE-FAULT TRIGGER
Range: Off, Any FlexLogic operand
Default: Off
This setpoint specifies the FlexLogic operand to capture the pre-fault data. The rising
edge of this operand 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 TRIGGER is "On". If the operand remains "Off" for 1 second, the element resets
and no record is created.
FAULT TRIGGER
Range: Off, Any FlexLogic operand
Default: Off
This setpoint 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. The distance to fault
calculations are initiated by this signal.
ANALOG CHANNELS 1 to 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 created. Up
to 32 analog channels can be configured.
The Event Data feature stores 64 FlexAnalog quantities each time an event occurs. The
relay is able to capture a maximum of 1024 records. The Event Data behaviour matches
that of the Event Recorder. This is a Platform feature and a 'Basic' option so it has no
dependencies.
There is no Enabling/Disabling of the feature. It is always 'ON'.
When changes are made to the Event Data settings, the Event data is cleared and the
Snapshot.txt file is deleted. The Event Record remains as is and is not cleared.

The relay provides an easy to use faceplate for menu navigation using 5 navigation
pushbuttons and a high quality graphical display. Conveniently located on the panel is a
group of 7 pushbuttons for Up/Down value selection, Enter, Home, Escape, Help, and Reset
functions. The faceplate also includes 3 programmable function pushbuttons with LEDs.
Fourteen other status LEDs are available, 12 of which are programmable.
