Figure 4.6 illustrates an example rotating display sequence. The active alarm
points are the first screens in the
ROTATING DISPLAY (see Alarm Points on
page 4.7). Each alarm points screen shows as many as 11 alarm conditions. The
relay can present a maximum of six alarm points screens.
The active display points are the next screens in the
ROTATING DISPLAY after
alarm points (see Display Points on page 4.10). Each display points screen shows
as many as 11 enabled display points (with 96 display points, the relay can pres-
ent a maximum of nine display points screens). If a display point does not have
text to display, the screen space for that display point is maintained.
