Entering the DATA Mode
To leave the configuration mode and enter the data mode, depress the MODE/NEXT switch repeatedly until
ConF is displayed on the front-panel display. Then hold the switch up for approximately five seconds until
the word dAtA appears. At this time the STATUS LED will extinguish. (Releasing the MODE switch before
five seconds has expired will return the display to the configuration mode.)
Automatic Scrolling
When the display is left at dAtA for 60 seconds, the display will automatically step through all of the read-only
registers (i.e., it will scroll) in the sequence of Table 4-3, then wrap around and repeat. This scrolling
process first presents the name of the next register of the sequence (for 0.4 seconds), then presents the data
of that register (for 0.4 seconds). This process will repeat endlessly while the relay remains in the data mode
unless deliberately halted.
To halt the display at a particular register, step the display to the desired read-only register using the NEXT
switch. (The registers will appear in the sequence of Table 4-3). Raising the MODE/NEXT switch (above
center) displays the name of the register arrived at (except when dAtA is displayed).
Holding the MODE switch up for five seconds or more when the word dAtA is displayed puts the relay into
the configuration mode. Leaving the display at dAtA for 60 seconds will cause it to scroll again.
Instrumentation Display
The first seven registers of the data mode display sequence (Table 4-3) comprise the real time data
instrumentation display. The first four registers indicate the current at the CT primarys of each phase in
kiloamperes. Registers 5, 6, and 7 of the sequence indicate the demand current (at the primaries in
