Front-Panel Display
The liquid crystal display (LCD) shows event, metering,
settings, and relay self-test status information. The target
LEDs display relay target information as described in
Figure 8 and explained in Table 4 .
The LCD is controlled by the navigation pushbuttons
(Figure 9), automatic messages the relay generates, and
user-programmed analog and digital display points. The
rotating display scrolls through the bay screen, alarm
points, display points, and metering screens. Each
display remains for a user-programmed time (1–15
seconds) before the display continues scrolling. Any
message generated by the relay because of an alarm
condition takes precedence over the rotating display.
