JPI EDM-830 Engine Monitor, 4 to 9 Cylinders

The EDM-830 is a J.P. Instruments advisory engine monitor with a colour TFT display for a standard 3 1/8 in instrument hole. It shows EGT and CHT for every cylinder with RPM, manifold pressure, fuel flow, oil, outside air temperature and percent power. Kits exist for 4, 6, 7, 8 and 9 cylinders. The primary engine instruments stay in the panel.

Colour TFT display, viewable in direct and indirect sunlight.
LeanFind with true peak detection supports leaning rich and lean of peak.
Programmable limits for over-temperature, EGT differential and shock cooling.
Adapts to 14 V and 28 V systems; operates from 7.5 to 35 V at 0.5 A.
A serial port takes navigation data from a GPS and sends fuel data back to it.
Temperature indicator to TSO-C43b; non-primary, installed in the US under FAA STC SA2586NM.

Display and leaning

The colour TFT display shows EGT and CHT bar graphs for every cylinder with RPM, manifold pressure, fuel flow, oil temperature and pressure, outside air temperature, bus voltage and percent power. Alarm limits are programmed by the pilot.

LeanFind works with true peak detection, rich of peak or lean of peak, and the display shows the temperature below peak EGT. Normalize view, EGT spread and shock cooling are shown alongside. Percent power needs fuel flow, RPM, outside air temperature and manifold pressure.

Mounting, power and connectors

The EDM-830 fits a standard 3 1/8 in instrument hole, with a mounting bracket behind the panel on the existing 6-32 screw holes. It mounts in portrait or landscape orientation, set from the front buttons. A flush-mount plate, PN 700830, is available as an option.

Power comes from a separate 5 A circuit breaker or a 2 A slow-blow fuse on the avionics bus. The instrument adapts to 14 V and 28 V systems, switches off below 9.8 V DC and is grounded at the engine.

Data, GPS and fuel flow

Engine data is stored in long-term memory for post-flight retrieval and downloads to a USB flash drive. The EZTrends charting software and a 1 GB memory stick come with the instrument.

A serial port accepts navigation data from a GPS (RS-232, TTL, RS-423 or RS-422) and sends fuel data to the GPS over RS-232. Fuel flow, fuel used and endurance are standard functions.

Variants and installation path

The kits EDM-830-4C, -6C, -7C, -8C and -9C cover four- to nine-cylinder engines and include the harnesses, power connector and mounting clamp. The RPM sensor is chosen for Slick or Bendix magnetos, including pressurized and dual-magneto versions. TIT, IAT, CDT and carburettor temperature are options.

Installation follows JPI Report No. 103 under FAA STC SA2586NM, with an FAA-approved flight manual supplement. The STC is a US approval and not an EASA approval. In a certified aircraft the installation is an approved modification, released with a Certificate of Release to Service.

Manufacturer documents, provided for reference. Before installation or operation, make sure you have the current revision.

Is the EDM-830 a primary engine instrument?

No. It is an advisory instrument. The primary engine instruments stay in the aircraft, and flight manual limitations based on them take precedence. The indicator and probes are approved as a temperature indicator under TSO-C43b. RPM and manifold pressure were tested under TSO-C43b and do not comply with TSO-C49a and TSO-C45; battery voltage is not approved under TSO-C43b.

Which kit fits which engine?

The kit follows the cylinder count: EDM-830-4C for four, -6C for six, -7C for seven, -8C for eight and -9C for nine cylinders. The RPM sensor depends on the magneto type, Slick or Bendix. Fit depends on the aircraft type, the engine model and the magneto type.

What does FAA STC SA2586NM cover?

STC SA2586NM covers installation of the EGT 100, 200 and 701 series temperature indicators in aircraft on its master eligibility list; P/N EGT-701 with (L) is the colour TFT display of the 730 and 830. In the Rev 14 list of 20 July 2008, RPM and MAP apply to 4- and 6-cylinder engines only. It is a US approval; installation in an EASA aircraft needs an approved modification.

What is included, and which options exist?

The kit includes all required harnesses, the power connector, a mounting clamp with screws, EZTrends software and a 1 GB USB memory stick; the RPM sensor for the chosen magneto type is included. JPI lists these options: TIT probe, OAT, IAT/CDT and carburettor temperature, CO detector and real-time data out.

How does the instrument alert the pilot?

The EDM-830 samples the engine parameters three times a second and warns when a value passes its programmed limit. Limits for over-temperature, EGT differential and shock cooling are pilot-programmable, and a battery voltage alarm is standard.
