the GTE. It indicates the pressure on the GTE is
below the preset limit.
This section is an alphanumeric display
device. The plasma display provides the EPCC
operator with machinery status and alarm
information required to control and monitor
the electrical equipment. The plasma display
can be operated in two different modes,
status/alarm or summary group status. The
bottom portion of the display is used for
DDI display in both modes. The modes are
controlled by the plasma keyboard. The plasma
display works the same as the other plasma
displays described in chapter 7.
METERS.--The meters from top to bottom
are POWER, CURRENT, VOLTAGE, and FRE-
QUENCY. The power, current, and frequency
meters are 270-degree LED meters. The voltage
meter is also a 270-degree LED meter, but it
contains a three-digit LED display on the meter.
The meters are black in color and the parameter
area illuminates red in color. Red area increases
around the 270-degree arch as the parameter
increases.
