2. General description
The Dorado MX3 kit is a system designed for application on pneumatic precision
seed drills, the main functions of which are:
 Check of the sowing distance and seed life for each row (max 12 rows);
the data for sowing distance and seed life is represented in numeric
format (value) and in analogue format (histograms)
 Audible and visual alarms in the event of sowing that does not comply or
the absence of fertiliser
 Calculation of the processed area; a total counter and a partial counter are
available.
There are also other functions available such as:
 Display of RPM fan and visual and audible alarms (RPMmax and RPMmin
programmable)
 Display of the depression related to the sowing system
The connection architecture of the Dorado MX3 kit is of modular and self-
configuring type; up to a maximum of 12 seed sensors can be controlled, to which 2
additional inputs for other sensors are added (feed-rate, RPM fan, vacuum gauge).
Each seeding ECU can handle 12 seed sensor inputs; a configuration connector
has been provided to connect its accessory. Each seeding ECU can be connected
indifferently to each wiring harness and the KIT will automatically recognise the
configuration. The diagram on the next page shows the main configurations (for
different configurations, contact Elettronica's Technical Department).

3.2 Virtual Terminal assembly
To assemble the Virtual Terminal, proceed as follows:
 Screw the suction bracket onto the rear part of the Virtual Terminal using the
supplied screws
 Fasten the suction bracket onto a clean flat surface. Otherwise, the Virtual
Terminal can detach itself and fall during operations
Note: We recommend installing the Virtual Terminal in front of the operator to
make it easier to use during the work cycle.

3.3 Sensor installation
The Dorado MX KIT can be equipped with the following sensors:
 Proximity inductive sensor, NPN, 12V, N.O. (or speed sensor)
 Magnetic sensor (or RPM)
 Seed sensor
 Vacuum gauge sensor
 Encoder sensor
3.3.1 Speed sensor installation
You can install the speed sensor anywhere there is mechanical movement,
applying a metal reference protruding by at least 7 mm
(Figure 4 - ref. <C>).
Set the gap between the sensor and the bolts at about 2/3 mm (Figure 4 – ref.
<B>).
Fasten the sensor supporting bracket (supplied) securely to a fixed part of the
vehicle structure. Fasten the sensor to the bracket using the nut and the lock nut.
The sensor must be installed so as to ensure speed reading with a speed of at
least 10 pulses / meter (1000 pulses / 100 metres) in order for the system to work
properly.
!
Warning
The sensor cable should be covered with a rubber sheath.

3.3.2 Magnetic sensor installation
The inductive sensor to detect turbine RPM must be positioned in front of metal
references with a diameter at least equal to the corresponding sensor and
protruding from any other metal mass by at least 7mm. The distance between the
sensor and its metal reference varies from 2 to 3mm.
The figures below show two different installation examples.

3.3.3 Seed sensor and the wiring harness installation
The seed sensors must be positioned on each single row of the seed drill so that
when the seed falls, it passes through the two seed sensor elements.
To install the wiring harness proceed as follows:
 distribute the wiring harness cables fastening them to the seed drill's air pipes
with clamps, paying attention to the numbers on the cables near the
connectors: cable no. 1 corresponds to row no. 1 of the Monitor, cable no. 2
corresponds to row no. 2 of the Monitor, etc... It is important to consider the
seed drill's first row (starting from either right or left) as "no. 1 row" and that the
other be connected in sequence: Figure shows an example of a six-row wiring
harness application taking the first row on the left of the seed drill, as
reference;
 position the junction box (A) at the centre of the seed drill, fastening it with
clamps;
To install the seed sensors proceed as follows:
 If the sowing elements of the seed drill are “high” with the dropping pipes that
bring the seeds to the ground, the seed sensors to be installed are code
10FOT-4RXTES (with external electronics) or 10FOT-4RXTIN (with internal
electronics) and must be placed at about half the length of the pipe itself.
 If the seed drill has "low" sowing elements and the seed falls directly from the
disc to the ground, the seed sensors to be installed depend on the type of seed
drill and must be directly fitted on the sowing element Figure , following the
indications on the datasheet attached to this manual (N.B. the datasheet is
specific to the brand and model of the seed drill used).
!
Warning
make sure that seed sensors do not obstacle the seed-drop or the
mechanical functioning of the sowing element.

3.3.4 Radar sensor and GPS installation
As an alternative to the speed sensor seen in sub-paragraph 3.3.1, it is possible to
connect non-MC elettronica radar or GPS sensors to the Seeding ECU, which allow
the system to reach the vehicle feed-rate.
These sensors can be connected to the VT 3.5 "by means of an optional accessory
ECU. Contact MC elettronica’s Assistance Service for more information.

3.4 Operation
3.4.1 Seed sensor recognition
The Dorado MX3 kit immediately recognises the number of ECUs and the type of
seed sensors connected to them: standard MC Elettronica seed sensors are
equipped with initial pulse for recognition;
When started during the initial test the following screen is displayed, where "HW V-
x.xx" and "SW V-x.xx" respectively indicate the 3.5” VT hardware and software
version.
Figure 10
Subsequently on the display the following work screen appears that can be
different depending on the number of ECU and seed sensors recognised; there are
4 basic configurations:
- Up to 6 rows
- Up to 12 rows
IT IS IMPORTANT THAT THE OPERATOR CHECKS THE CORRECT
ACQUISITION OF THE SEED SENSORS EVERY TIME IT IS SWITCHED ON:
AFTER INITIAL RECOGNITION THE SEED SENSORS THAT HAVE NOT BEEN
DETECTED ARE NO LONGER MONITORED UNTIL IT IS NEXT SWITCHED ON
