Successful access is indicated by the display example shown below:
The = > > prompt signifies that Access Level 1 and 2 commands may be entered. The
ALARM contact is pulsed closed for one second (if no alarm condition exists, such as self test
failure) for any Level 2 access attempt, successful or otherwise.
DATE mm/dd/yy
To display the current date stored in the internal calendar/clock, type
DATE <ENTER>.
To set the date, type
DATE mm/dd/yy <ENTER>.
To set the date to June 20, 1990, enter:
The relay responds by setting the date, pulsing closes the ALARM, and the year is stored in
EEPROM.
EVENT n
You may view event records using an event report. To display the event report for the nth
event, type
EVENT n <ENTER>.
The parameter n is 1 for the most recent event and 12
for the oldest event stored in the relay memory. If n is not specified, the report defaults to
one.
To inspect the newest report type
EVENT 1 <ENTER>,
or
EVE <ENTER>.
The report
provides the relay identifier string, date, and time the event occurred. The next part of the
event report displays eleven cycles of data for the five current channels (IPOL, IR, IA, IB,
and IC), three voltage channels (VAB, VBC, and VCA), and the states of the internal relay
elements, outputs and inputs. Next, the report shows the type of event, fault location in
miles, primary ohms to the fault location, duration, and the maximum phase current measured
at the midpoint of the fault. When a fault causes a trip, the fault targets are shown as well.
The relay and logic settings are displayed at the end of the report.
