Mechanical Installation Considerations

PROGRAMMER INSTALLATION

Mounting Considerations
The EMS Series unit is designed to mount in the aircraft instrument panel within view and reach of the

pilot. The primary unit location should minimize pilot head movement when transitioning between
looking outside of the cockpit and viewing/operating the EMS Series unit. Maximum recommended
viewing angle should be no more than 20 deg. The maximum mounting angle the EMS can accommodate
is 12 degrees longitudinal axis and 0 degrees lateral axis. The location should be such that the EMS Series
unit is not blocked by the glare shield on top, or by the throttles, control yoke, etc. on the bottom. Use
aircraft installation standards for mounting and support of the EMS programmer.
EDM should be mounted on the firewall so that both sides can be accessed for service. Do not run
wire along fuel lines for support. All wiring should be mounted above fuel and hydraulic line for safety.
Never mount wiring directly on support structures, use Adel clamps or wire stand-offs.

Wiring Considerations
Use AWG #24 or larger wire for all connections in the interior of the aircraft unless otherwise specified.

Engine wiring should not be smaller than AWG #22. The standard crimp pin contacts supplied in the
connector kit are compatible with up to AWG #20 wire. In cases where some installations have more than
one component sharing a common circuit breaker, sizing and wire gauge is based on length of wiring and
current draw on units. In these cases, a larger gauge wire such as AWG #20 may be needed for power
connections. Do not attach any wires to the outside of the EMS or route high current wires within six (6)
inches of the programmer. Ensure that routing of the wiring is not exposed to sources of heat, RF or EMI
interference. Check that there is ample space for the cabling and mating connectors. Avoid sharp bends in
cabling and routing near aircraft control cables. Do not route the COM antenna coax near any EMS
components.

RFI/EMI considerations

The EMS programmer is shielded and does not generate any appreciable level of electromagnetic
interference. The EMS itself has been internally protected from RF interference and has been tested
under fairly extreme conditions, such as close proximity to
transmitting antennas. However, it is always good practice
to insure that such antennas are properly shielded and not
routed directly over or under sensitive panel-mounted
electronic equipment. Most problems in this area are the
result of improper RF shielding on transmitting antennas,
microphone cables, and the like.

Pitot and Static Connections

The TruTrak EMS requires connections to the Pitot and
static lines. The preferred m

ethod of this connection would

be tee fittings near the aircraft’s airspeed indicator.

Operating controls

As with our autopilot products, extensive attention has been given to providing the simplest operation.
No sequential pressing of buttons is required to reach basic control functions. Active descriptions of Knob
or Button functions are labeled on display above. If there is a second EFIS connected by way of the TCB­A & B wires, information will be communicated between the two units.

BARO Selection (Backup Gauges only)

In the TruTrak EMS display, barometer BARO is
set by rotation of the right dedicated knob. The
Baro reading is displayed in the Altimeter. The
yellow band along with the numerical VS
displayed above indicates VSI direction and speed.

GPS Information

The T&B DG requires GPS NMEA information to
function correctly. If the primary serial connection
and communication protocols have been setup
correctly, the EMS T&B gauge will display the
DG. Also, the timer is updated with GPS NMEA
information.

Dimming

Dimming of the display is accomplished by rotating the left knob, DIM rotating the knob Counter Clock
Wise to reduce the display illumination. External dimmer input will control the button illumination.

CHT /EGT Page

This page displays a detailed readout of all the CHT and EGT
sensors. Also, PEAK readings will be marked on this page. The
highest reading will be the CHT and EGT that is displayed on
the MAIN page.

TIMER Page

This page displays all the timers that are tracked. Detailed fuel
information and contact switch position along with voltage and
amp indications if installed.
The TIMER Page will be displayed on power up so that fuel
information can be updated. Also, the trip and leg timers can be
reset if needed.
Any parameter that enters a yellow ARC will change the reading displayed to yellow. See VOLTS. If the
parameter progresses to the red position the EMS / EFIS will display a warning box at the bottom of the
screen.

WARNINGS

There will be a warning box that will be displayed at the bottom
of the screen when a parameter first enters the red arc.
See OIL PRESSURE.

Pressing the button below ACK will remove the warning box
and the button below VIEW will change the page to the detailed
view page if different than the current page.

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
#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.

CALIBRATION

FUEL, TACH, SNSRS, FLAPS, TRIM, SPEEDS, & BALL

These pages allow the selection and calibration of the Fuel level, Tach, Sensors, Flaps and Trim
indicators. Also to set the Baud rate and center the ball in the T&B after installation.

FUEL
The type of and # of fuel sensors MUST be selected first (see CONFIG & SNSRS).

Calibration of tank / guages, there are a total of 15 PTs (calibration
points) possible, not all are necessary.
Select the tank to calibrate, with the tank empty, the first PT #0 is 0
GAL, press [enter]. Add fuel, in whole gallons until the number of
GAL over the displayed gauge just starts to move. Wait until the
number stabalizes. Enter the gallons added by rotating the left knob
and press [enter], PT #1. The gauge colors and number of GAL are not
correct until the calibration are complete. Continue adding fuel, each
PT# should have the total amount of fuel in the tank at that time and
wait until the number stabalizes. When the number displayed STOPS
changing when adding fuel, STOP. This is the last PT # even if the
tank is not full, enter the total gallons in the tank by rotating the left
knob, wait until the number stabalizes. Press DONE.
The sender can not measure fuel past this point. This is NOT to total
fuel used in calcuating remaning fuel. Only the @ amount of fuel in
the tanks.
