Command Explanations
DAT Command (View/Change Date)
DAT displays the date stored by the internal calendar/clock. If the date format
setting DATE_F is set to MDY, the date is displayed as month/day/year. If the
date format setting DATE_F is set to YMD, the date is displayed as year/
month/day.
To set the date, type DATE mm/dd/yy <Enter> if the DATE_F setting is
MDY. If the DATE_F is set to YMD, enter DATE yy/mm/dd <Enter>. To set
the date to August 10, 1999, enter:

You can separate the month, day, and year parameters with spaces, commas,
slashes, colons, and semicolons.
EVE Command (Event Reports)
Use the EVE command to view event reports. See Section 12: Standard Event
Reports and SER for further details on retrieving event reports.
GRO Command (Display Active Setting Group Number)
Use the GRO command to display the active settings group number. See
GRO n Command (Change Active Setting Group) on page 10.35 and Multiple
Setting Groups on page 7.18 for further details on settings groups.
HIS Command (Event Summaries/History)
HIS x displays event summaries or allows you to clear event summaries (and
corresponding event reports) from nonvolatile memory.
If no parameters are specified with the HIS command:
=HIS <Enter>
the relay displays the most recent event summaries in reverse chronological
order.
If x is a number (1–23):
=HIS X <Enter>
the relay displays the x most recent event summaries. The maximum number
of available event summaries is a function of the LER (length-of-event report)
setting.
If x is “C” or “c,” the relay clears the event summaries and all corresponding
event reports from nonvolatile memory.
The event summaries include the date and time the event was triggered, the
type of event, the fault location, the maximum phase current in the event, the
power system frequency, the number of the active setting group, the reclose
shot count, and the front-panel targets.
NOTE: After setting the date, allow
at least 60 seconds before powering
down the relay or the new setting may
be lost.
