Introduction
This instrument is intended for ultralight, microlight, homebuilt and
experimental aircraft. The purpose of EEM MOT 01 type display is to
present key engine status information to the pilot. Version FE03.04
displays fuel level, oli temperature and pressure, voltage, flight time,
hobbs and number of recorded threshold crossings.
The device is equipped with an in-built colour display protected by anti-
reflective coated glass. The encoder knob & push-button located in the
front provides user interaction with the device. The electric connector,
hardware and software identification plates are located in the back of the
casing (Fig. 1)

This instrument is not certified by the FAA and EASA. Fitting of this
instrument to certified aircraft is subject to the rules and conditions
pertaining to such in your country. Please check with your local aviation
authorities if in doubt.

during installation and in its operating phase. This document does not
contain rules and guidelines on operation of aircraft instruments at large.
Read the manual thoroughly before turning on the instrument and
precisely follow the instructions to install and configure it. This manual
does not replace instructions on installation, maintenance and operation
of this device in a particular airframe - these are to be prepared by the
user. Instructing the pilots and maintenance personnel on operation of the
instrument is also the responsibility of the user.
Operation of this instrument is the sole responsibility of the pilot in
command (PIC) of the aircraft. This person must be proficient and carry
a valid and relevant pilot’s license. This person has to make themselves
familiar with the operation of this instrument and the effect of any
possible failure or malfunction. Under no circumstances does the
manufacturer condone usage of this instrument for IFR flights.
This manual defines the scope of maintenance measures the user is
authorised to conduct on their own. Any repairs or modifications outside
this scope conducted by the user or contracted to a third party, as well as
using non-original parts and subassemblies voids the warranty, relieves the
supplier from any liability, making the instrument lose the status of the
product of Auto & Aero Technologies Sp. z o.o. with all the resulting
consequences.
2. Handling in transport and storage
1. The EEM MOT 01 monitor is bubble-wrapped to protect it against
vibration and other physical damage, and packed in a cardboard
box together with the warranty card.
2. The display must be stored and transported assuring that:
othe ambient temperature stays in the range of 10 40°C
othe ambient relative humidity stays in the range of 1090 %,
safe from condensation.
3. The display should be protected from water.

3.3. Mounting
The display should be located conveniently within the pilot’s view in the
control panel in the cockpit. The diameter of the mounting hole to be cut
in the panel is 80mm. It is recommended that the display is installed from
the rear side the control panel. The display is to be fastened to the panel
by means of four M3 screws that are located symmetrically to the centre
of the mounting hole in the spacing of 62.9 mm (Fig. 3).
Fig. 3. Mounting hole and screw holes measurements (not to scale)
3.4. Power and wiring
The EEM MOT 01 display is powered from the aircraft power system.
Power specifications: nominal supply voltage 12V, acceptable supply
voltage range 8 ÷30V, current < 85mA.

The EEM MOT 01 display is connected to the system by in-built MOLEX
Ultra-Fit 3.5 mm 6 pin male connector located at the back of the
instrument. A schematic diagram of the connection is shown in Figure 4
and in Table 1.
The power supply (pins no. 5 and 6) requires 0.5 mm2wires.
Data bus (pins no. 3 and 4) requires twisted pair wires (2 x 0.5mm2)
according to DIN VDE 0814 (Fig. 4). Twisting should continue to the pins of
the connector.
Pins 1 and 2 are to be left unconnected.

4. Operation and maintenance
The display is to be connected to EMS DAQ R2.
The front panel of EEM MOT 01 is composed of three elements: the
display, two status diodes (alert indication), and the encoder knob & push-
button for setting parameters (Fig. 5).
Rys. 5. Front panel of EEM MOT 01 Display
The EEM MOT 01 display displays values of flight parameters that are
either directly measured or calculated by the system. The display starts
automatically as the power is turned on.
As shown in Figure 6, the monitor with FE03.04 software version presents:
a) Oil pressure –in the upper left quarter of the display;
b) Oil temperature –in the bottom left quarter of the display;
c) Fuel level –bar graph on the right;
d) Flight time (measured from the last start of the engine) –
digits in the bottom left of the display;
e) Hobbs (total engine running time) - digits in the bottom right
of the display;
f) Voltage –the upper left of the display;
g) Number of recorded threshold crossings –the upper centre of
the display (e00);

As the aircraft operates within “normal” range of the parameter in
question, the instrument displays values in green, and status diodes are
green. If the threshold level is being exceeded, the instrument informs the
pilot by changing both the colour of displayed figures and the colour of
status diodes. Exceeding the alarm threshold is additionally indicated by
the diodes flashing red. The pilot can switch off flashing by pushing the
encoder knob. Figure 7 presents the idea of colour codes and
warning/alarm indication.
Thus, information on the status of a flight parameter is presented in two
ways:
1) by means of the colour of two status diodes according to the
following colour code:
a) green –engine parameters within normal range;
b) orange –warning;
c) red –alarm;
2) by means of the colour of digits and bar graph (if applicable)
presenting the value of the parameter:
a. green –engine parameters within normal range;
b. orange –warning;
c. red –alarm;
The status information is obtained as a result of analysis conducted by the
instrument on the basis of digital input transmitted by the measurement
modules of the system.

Both diodes are always of the same colour corresponding to the status of
the parameter that assumes “the worst” value.

5. Service, diagnostics and repairs
5.1. Service life
a) TBO of the display is not defined.
b) In the case of failure or error, the display must not be used any
more.
5.2. Checks
The following checks are recommended:
1) At pre-flight check:
a. Turn on the power to check if operational;
2) After 100 hours of flight:
a. Check the instrument’s electric connections;
b. Turn on the power on to check if operational.
5.3. Cleaning and conservation
The screen is to be buffed with water-damped soft cloth. Optionally, if very
dirty, can be cleaned with cloth sparingly damped with mild soap solution
or with a liquid dedicated for liquid crystal displays. Caution: the surface is
vulnerable to scratching.
5.4. Troubleshooting
a) If the screen stays blank when power is applied, turn off power
supply and verify power connection. Ensure that your power
supply is capable of supplying at least 8 volts, and no more than
30 V.
