Temperature Units (°F or °C)
•
°F
temperatures in the digital display are in Fahrenheit degrees.
•
°C
temperatures in the digital display are in Celsius degrees.
To change the display of engine temperatures see “Changing the
Alarm Limits” on page 45.

Cylinder Numbers and Dot Index
A row of numbers
1
through
6
and the letter
T
are the column labels for
the analog display. The
1
through
6
are the cylinder numbers. If the TIT
option is installed, the
T
denotes the last column is displaying Turbine
Input Temperature (TIT) as a column. If the
T
is absent and the Oil
temperature option is installed, the last column displays Oil temperature.
If both TIT and Oil temperature options are installed, the last column
displays TIT and the missing segment displays Oil temperature. The
highest Oil temperature segment will flash only when the digital display
shows OIL. The highest TIT segment will flash on when the digital
display shows TIT. A round dot under the numbers 1 through 6 indicates
that particular column is shown numerically in the EGT and CHT digital
display.

Bar Graph EGT and CHT
Each column in the bar graph is composed of a stack of segments. The
total height of each column represents the
EGT
and the missing segment
in the column represents the
CHT.
•
In the Percentage view, the EGT, TIT, and Oil temperature
resolutions depend on the programmed red line limits.
•
CHT is displayed by a missing segment and should be
interpreted as follows: a missing segment corresponds to the
CHT in 25 F° increments, starting at 300°F at the bottom. In
the example shown here, the CHT is 400°F. If the EGT bar
is lower than the missing CHT segment, then the CHT will
be indicated by a single isolated lighted segment.
The CHT display is the not affected by mode or view.
‡
Percent HP or RPM (EDM-800 only)
Displays percent of rated HP or RPM depending on pilot programming.
Digital Display
Beneath the bar graph is the 9-segment alphanumeric display.
