2. Read This First

The following notes apply to a new installation. Read this section before proceeding.

The JPI warranty found in the back of the pilots guide clearly states that JPI will replace defective parts under

warranty, but does NOT cover labor to remove or install any parts.

The most common cause of probe problems is poor terminal crimps. Crimp ring terminals with AMP tool or

equivalent. Fold back the wire double before crimping terminals.

Do not use aluminum fittings or Teflon tape or pipe sealant with the FXT-201 or FXT-231 fuel flow transducer.

Write down the K-factor engraved on the side of the fuel flow transducer here _______. Once the transducer is

installed and covered with the fire sleeve, you will not be able to access this K factor.

Determine the locations of all holes before drilling to ensure that nothing interferes with the probe, clamp, clamp

screw or wire.

Provide service loops at the instrument so that it can be moved for maintenance or troubleshooting.

Thermocouple wire length is not critical. Trim to required length, allowing for service loops at the engine so that

probes can be swapped with probes on adjacent cylinders for troubleshooting purposes.

Dress all wires away from high temperature components such as exhaust stacks.

Never splice thermocouple wire using copper wire. Use only K-type thermocouple wire. Solder using zinc

chloride flux such as Nokorode brand – rosin flux alone will not work.

Observe correct polarity on all probe wires. Connect like colors together (red to red, yellow to yellow).

The instrument must be grounded at the engine, not at the avionics ground.

Record the installation of the EDM-900 or EDM-930 on a FAA form 337. Make an entry in the aircraft logbook.

Note: Removal of probes, sensors and the instrument is the reverse of the installation procedure.

4.1 Remote Alarm Light EDM 900

The remote alarm light is a Red or Yellow light depending on the alarm condition. The EDM-900 incorporates a

single light that alerts the pilot that a problem existing within the engine. This light is place in with the primary flight

instruments and required only if the display is more than 8 inches from the center of the instrument “T” to a max of

21 inches. It is a single light that changes color with condition and the label associated with the light must be lit by

a post light or such that you can see the word “ENGINE”.

4.2 Remote Alarm Display (RAD) Operation EDM-930

The RAD is a 0.2” high, 8 character independent display found on the EDM-930 only. The RAD will still function if

the main display is inoperable. An alarm—such as the CHT is 480° on cylinder number 2—is displayed as

480CHT2. The label CHT2 will flash whenever an over-temperature exists and will extinguish when the temperature

falls below the limit temperature. Other alarms would be displayed as, for example: 2780 RPM.

The RAD is located directly in front of the pilot and displays digital caution and limit excedances when any of the

parameters have reached its preset trigger point. Whenever limit alarms are not triggered, the RAD continuously

displays MAP and RPM.

On initial startup or whenever power is turned on, the words EDM-930 PRIMARY” are displayed, followed by the

make and model of the aircraft with STC information for which the primary limits were set

Alarm hierarchy for the EDM-900/930

When a measurement limit is reached, the pilot should momentarily depress the STEP button on the EDM-900/930

instrument to extinguish the particular flashing alarm acronyms. If another function has also reached its limit, that

label will then begin to flash. The pilot should continue to monitor the affected parameters as he would if a

conventional analog display had reached a limit. The bar graph functions of CHT, EGT, and TIT remain displayed

for easy reference should one of these limits be reached. Alarm hierarchy is shown in the table below.

Dimming

Automatic dimming is provided to dim both the panel display and the remote alarm display. Dimming can also be

accomplished manually to change the Automatic setting. Tapping the far right button below the display decreases

brightness. Continuously holding this button increases brightness. The display starts up in the max brightness mode.

EDM-900 system mounts in a 3.125 inch diameter instrument panel hole in either a portrait or landscape position

depending on panel hole location. By holding the Step button ( first on left) for approx. 10 seconds and arrow will

appear on the display showing which way the rotation will use as up. Use the LF (Second from left) button to index

the rotation arrow. When the proper position is achieved, tap the step button Tap STEP to save the new rotation.

At this point properly the rotation will be saved and the unit will reboot to the new rotation. The rotation will not

occur if the engine is running.

5. Locating and Installing the Indicator and Remote Alarm Display (RAD and Alert Light)

Single Engine Aircraft EDM-900/930

A) The EDM-900/930 display should be located as close as possible to the pilot with an unobstructed view

and for easy access to the buttons on the instrument. The least desirable view angle is landscape looking

up. To improve the view angle call the factory. A remote display is also provided for alarm indications and

should be directly in front of the pilot.

B) The RAD PN-790749 mounts in a 5/8 inch hole in the panel directly in front of the pilot for the EDM-930

and an alert light for the EDM-900 is mounted in a 3/8 dia hole.

The diagram below should be used as a guide for cutting and drilling the mounting and buttonholes in the

instrument panel. The dimensions shown are for the finished cutout. Allow extra clearance for any panel finish such

as powder coat. The EDM mounts from behind the panel through this cutout. Fabricate the appropriate cut-out

using the fig below as a guide. If the panel has too many holes for a clean installation, it is recommended that a

0.10” aluminum overlay panel be constructed and installed over the original instrument panel and the EDM be

installed into this overlay panel. The Remote Alarm Display PN-790749 mounts in a 5/8 inch hole in the panel

immediately above the Attitude Gyro / D.G. / HSI +/- 0.5 inches from their centerline directly in front of the pilot.

Mounting bracket for the EDM-900

EDM-900 Model: Mounts in a standard 3.1/8” instrument hole. First, place the mounting bracket on the

instrument and tighten the clamp hex screw until you can just remove the instrument from the bracket. The

Mounting bracket is then placed behind the instrument panel hole and screwed (6-32 x ½” screws) in place using

the existing holes. Three screws should be used leaving one hole vacant on either side of the hex screw. Locate

the hex screw in a location that you can easily get to from the rear of the panel. The body of the instrument is 3.0

inches in diameter and 2.0 inches deep less connectors.

5. EDM Display Installation

Choose the Proper Installation Location

The display is best located within the natural scan and easy reach of the pilot. The recommended mounting location

is defined as the distance from the vertical centerline of the Primary Flight Instruments to the outer edge of the

further most gauge displayed on the EDM.

HORIZONTAL ORIENTATION:

The EDM display may be mounted from the vertical centerline of the Primary Flight Instrument “T” to a maximum of

21” to the further most gauge of the EDM display and to the left of the centerline as much as needed.

VERTICAL ORIENTATION:

The EDM display is to be mounted within +/- 10” from the horizontal centerline of the Primary Flight

Instrument “T”. The installer should insure that the EDM display is not obstructed by either

the glare shield or the control wheel.

The installing A&P and IA must insure that the installation location complies with the viewing angle requirements

listed above.

6. EDM-900/930 Key information installation

Aircraft specific configuration information is loaded differently on both the EDM-900 and the EDM-930. The

configuration data is the same for both instruments. The data for the EDM-900/930 is loaded via the mini USB port

on the EDM-900 and a standard USB port for the EDM-930.
