1. General information
This manual contains binding information, guidelines and warnings for safe
handling and maintenance of this particular instrument before installation,
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 device 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 module 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

The module is connected to the system by means of screw connection
terminal blocks attached to printed circuit plate inside the casing. A
schematic diagram of the connection is shown in Figure 3.
The power supply requires 0.75 mm2wires.
Sensor connection requires 0.5 mm2wires.
Thermocouple wires should be attached directly to the module’s
connector.
Data bus (RS0, RS1, RS2) requires twisted pair wires (2 x 0.5mm2) according
to DIN VDE 0814. Twisting should continue to the pins of the connector.
Power grounding to the battery clamp by means of a cable as short as
possible (no longer than 0.5m).

The occurrences of threshold crossing are recorded separately according to
their type. The system remembers four last occurrences. Information on
them is downloadable by means of a diagnostic connector, a converter,
and a dedicated software. These logs (all or selected) can be cleared by the
supplier of the aircraft and by the user.
The EMS DAQ R02.01 Module analyses and records statistics of selected
parameters of engine and aircraft operation. These parameters are listed
in Table 4. For each parameter, four value ranges are defined. The module
records the following data:
a) Number of instances of a parameter entering a specific range,
b) Total duration of a parameter assuming values from a specific
range.
The data are recorded separately for each parameter and for each of four
value ranges. Information on the statistics is downloadable by means of a
diagnostic connector, a converter, and a dedicated software (not supplied
with the device). The statistical records (all or selected) can be cleared
from the module only by the supplier of the aircraft.

5. Service, diagnostics and repairs
5.1. Service life
a) TBO of the module is not defined.
b) In the case of failure or error, the module 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 (the EEM MOT 01
FE… monitors should display data);
2) After 100 hours of flight:
a. Check the instrument’s electric connections:
Remove the lid of the monitor casing;
Check if wires sit firmly in screw connection terminal
blocks,
Check for wire damage as frayed insulation;
Place wires flatly and in parallel in the case to avoid
overlapping at the exit from the casing,
Attach the lid.
b. Turn on the power on to check if operational (check if EEM
MOT 01 FE… monitors display data);
c. Read/download EMS DAQ R02.01 records.
5.3. Cleaning and conservation
The casing is to be buffed with water-damped soft cloth. Optionally, if very
dirty, can be cleaned with cloth sparingly damped with mild soap solution.
Caution: avoid spilling liquids over the device.

5.4. Troubleshooting
a) If information is not displayed on some of the monitors (type FE…)
when power is applied (Fig. 8), check connection inside
measurement module. Check:
power connection; ensure that your power supply is
capable of supplying at least 8 volts, and no more than
30 V.
data bus connection (RS0);
Fig. 3. Indication of no connection to measurement module
a) If the system does not react to brightness adjustment, check
connection with AUX AVS 01 (RS1);
b) In the case of the module’s failure or malfunction, turn power off
and on again.
c) If the above does not solve the problem, the module needs to be
replaced.
d) A defective module must not be used.
