NINE CYLINDER EDM
To have a nine (9) cylinder EDM system the EDM must be setup using the PC TruTrak software.
With a nine (9) cylinder system pin 29 (Contact #1) of the 37 pin DB connector (J1) MUST be grounded to show
cylinder # 7, 8, 9. When the switch is open the EMS display will show CHT/EGT #1-6. When the switch is closed the
display will show CHT/EGT 7-9 in place of 1-3. #4,5,6 will NOT be reported
. This will also change the state of Contact
#1 on the third display page.
FOR AIR PRESSURE OPERATION
The EDM is designed to use a 0-1000 PSI sensor that has a 4-20 ma output. This sensor output must be connected to
pin 32 on the 37 pin DB (J1) connector. Sensor power can be connected to pin 31 if aircraft voltage.
Currently, Air pressure will be displayed under the CARB temp Heading. The display will read in degrees F, BUT, in
actuality it will be in PSI. If the UNITS are changed to Celsius the air pressure will be wrong, the display MUST be in
Fahrenheit.
Unless there is access to the TruTrak setup programming software from the PC, the user MUST NOT change the
CARB, TACH, EGT#, CHT# settings. Doing so will result in the unit not functioning properly.
