EGT-100 Operations & Installation Manual – Ver. 1.9 – June 5, 2003
1. Introduction
Your EGT-100 Exhaust Gas Temperature Indicator will provide you with years of
reliable service and generally outlast the life of your aircraft. The instrument is
constructed from the highest quality components and has a design life in excess
of 100,000 hours.
It is the most reliable instrument of its kind. Gone are the days of questioning the
accuracy or operation of the instrument. No stuck needles, erroneous readings or
instruments that keep you guessing as to their operational status.
Every reading you will see displayed on your instrument has been validated at
least 256 times before you see it. This all happens in less than a second. When
you see the result you know the instrument is functioning correctly as it is
monitored by an independent microprocessor just to ensure that it is functioning
correctly. In turn the main processor validates the independent monitoring
processor. Any failure detected in either processor and your instrument display
will be shut down or an error message displayed – depending on the failure
status.
2. Display
The main display of the instrument displays a graphical representation of the
temperature of the selected cylinder on the bar display, provided the temperature
is within the defined limits set by the user. The lower four-digit seven-segment
display provides a mathematically computed display of the specific temperature.
The
A M S
switch allows you to select the various functions of the instrument.
When the switch is placed in the
A
position the instrument is placed in the
AUTOMATIC
mode. In this mode it will select and display the information for the
hottest cylinder.
When in the
M
position the instrument allows
MANUAL
selection of the function
of choice. Available functions are:
STEP, 1, 2, 3, 4, 5, 6
, (5 and 6 only available
on 6 cylinder models) where the numbers correspond to the cylinder number to
be monitored. In the
STEP
mode the instrument will sequentially step through all
cylinders.
Moving the
A M S
switch momentarily to the
S
position will allow movement
between the manually selectable pages.
