4.9 CYLINDER ANALYZER SYSTEM OPERATION
The engine analyzer system displays all cylinder information both
graphically and digitally. Full color reference marks are provided for
cylinderheadgreen,yellowandredlinetemperatures.
'NORMAL MODE' - The system powers up in this mode and is ready for
flight. The Diamond Graph system displays CHT between the green,
yellow and red range marks, left to right, one through four. EGT graphics
are displayed above the CHT redline marks where they can be easily
observed. A defective CHT or EGT probe will leave the respective graph
blank. A flashing CHT graph indicates a cylinder is too hot or is being
shockcooled.
'LEANING MODE' - Leaning mode is selected by pressing 'BUTTON 1'
while in 'Normal Mode'. The entire Diamond Graph display is
temporarily used for precise high resolution leaning. The display can be
returned to the 'Normal Mode' by pressing 'BUTTON1' again. Notice that
left and right 'brackets' appear on the sides of the graphs when in
'Leaning Mode'. 'Leaning mode' is not allowed if a EGT probe was
defective at power up. A flashing EGT graph indicates that the leanest
EGThasbeendetected.
The digital display shows the temperatures for each EGT and CHT pair
and periodically shows the cylinder number (ex: 'E1' 'C1'). A warning
message is shown if a cylinder has reached 'red line' temperature (ex: 'h2'
for hot cylinder 2), or is being 'shock cooled' (ex: 'c3' for cooled cylinder 3).
