Individual parameters can be excluded from the Automatic mode: tap
STEP to enter the Manual mode. Tap STEP to index to the parameter
you want to exclude. Then tap both the STEP and LF buttons
simultaneously. Excluded parameters display a decimal point before the
parameter name. For example:
Included: I84 OIL Excluded:
I84 .OIL
Tapping the STEP and LF buttons simultaneously will toggle back and
forth between include and exclude.
• Every time you turn on the EDM, all parameters are reset to be
included.
• All installed parameters are always displayed in the Manual mode.
Exclusion only applies to the Automatic mode.
• All parameters are checked for alarm conditions every second
regardless of their included or excluded status.
Manual Mode
Just tap the STEP button. Use the Manual mode when you want to
monitor one specific parameter such as shock cooling during descent, or
a particular cylinder temperature during climbs. To change to the Manual
mode, tap the STEP button once. Subsequent taps will index the digital
display through the parameter sequence (see “Parameter Scan—Systems
without Fuel Flow Option” on page 10). To exit the Manual mode and
return to the Automatic mode, either tap the LF button and then tap the
STEP button or wait 15 minutes (see “How to Change Modes” in the
front of this manual). You may disable the Automatic mode by setting
“0” for scan rate.
LeanFind Mode—Leaning Rich of Peak
JPI’s EDM-700 and EDM-800 provide two methods of leaning: lean
rich of peak (LEAN R) or lean of peak (LEAN L). The standard
method is to lean about 20° rich of peak. With the advent of GAMI
injectors it is now possible to set the mixture lean of peak—saving fuel
and running the engine cooler. Teledyne Continental recommends lean of
peak for the Malibu. This manual primarily describes the rich of peak
