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).

3.1 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.

Figure 3 - 3.5” Virtual Terminal assembly

3.2 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

3.2.1 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.

Figure 4 - How to install the speed sensor

3.2.2 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.

3.2.3 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 7 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 TES type (with external electronics) or TIN type (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 9, 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.

3.2.4 How to install the seed level sensor

The capacitive sensor for the product level should be positioned so as to verify when the level of product in the tank decreases and goes below the reserve limit. The capacitive sensor can be installed inside the product tank Figure 10 - example 1) using a fixing bracket (not supplied) or it can be fitted directly on the tank body Figure 10 - example 2) and attached using its nut and lock nut. It is important for the front part of the capacitive sensor to come directly into contact with the product: this way, by positioning the head of the sensor in correspondence of the minimum level, when the sensor is covered by the product (Figure 10 ref. <1> examples 1 and 2) it does NOT emit an alarm signal, while instead when the head of the sensor remains

uncovered during operation, the relative alarm is activated.

EXAMPLE 1: fixing the sensor inside the tank, 1 sensor

EXAMPLE 2: fixing the sensor on the tank frame, 2 sensors

3.2.5 Radar sensor and GPS installation

As an alternative to the speed sensor seen in sub-paragraph 4.2.2.3.1, 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.

Figure 11

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.

3.3 Operation

3.3.1 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 12

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 3 basic configurations:

- Up to 6 rows - Up to 12 rows - Up to 24 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

3.5.1.1 Analogue display

The analogue display in histograms is based on the programmed sowing distance or seed life value (target) (see Programming chapter); the programmed value is assigned the reference of 100% and the histograms provide information concerning the quality of sowing detected, in the range of 100+/-50% according to the following screen :

The colouring of the histograms varies in relation to the alarm threshold set (see Programming chapter): the histogram remains green (or "neutral" until the sowing distance and seed life value detected remain within the programmed threshold, while it becomes red (with an acoustic signal) when the values detected exceed the threshold; in the following example the alarm threshold is set at 10%:

3.5.1.3 Display in PASSAGE mode

The Dorado MX3 kit can work in COUNTER mode, as referred to by the information provided in the previous paragraphs, and in PASSAGE mode; in the latter mode, the sowing distance or seed life are not calculated but are only checked by the presence or not of pulses (for further details see the Programming chapter). In passage mode, the numerical indications of the sowing distance and seed life values are replaced by horizontal dashes; the conditions of normal work and alarms are shown in the following images.

3.5.1.5 Viewing the excluded rows from inspection

The Dorado MX3 kit will however verify the coherence of the signals from the photocells, signalling an alarm if one or more of the photocells on the rows excluded from the control still continue to send pulses (e.g. mechanical exclusion mechanism of the faulty row); below are some examples :

Row no. 12 was excluded from the seed inspection and the seed sensor is not

detecting a pulse.

CORRECT

Row no. 12 was excluded from the seed inspection but the exclusion device was not activated or it did not work and the seed sensor of row 12 is still detecting

the seeds;

4. Programming

In the Dorado MX3 kit there are 2 different types of programming available:

- Specific programming for the Virtual Terminal

- Specific programming for seeding ECU

THE 3.5” VIRTUAL TERMINAL MAY BE MATCHED TO DIFFERENT TYPES OF MC

ELETTRONICA ECUs (SOWING, SPRAYING, HAY-MAKING, ETC.) THEREFORE THE

GRAPHIC INTERFACE DEPENDS ON THE ECU CONNECTED AND IS DIFFERENT IN

DIFFERENT CASES, HOWEVER THERE ARE SOME GENERIC PARAMETERS THAT APPLY

TO ALL THE APPLICATIONS (E.G. METRIC OR IMPERIAL UNIT OF MEASUREMENT) AND

THAT ARE THUS PROGRAMMABLE IN THE VIRTUAL TERMINAL WHILE THE SPECIFIC

PARAMETERS FOR EACH APPLICATION (E.G. SOWING DISTANCE) ARE

PROGRAMMABLE IN THEIR RESPECTIVE ECUs VIA THE VT;


Dorado MX3 kit

34

4.1 Virtual Terminal programming

This programming phase is accessible only when switched on, during initial testing when the screen display with the logo appears, with the sequence described below:

1. LANGUAGE: system operation language selection.

[Italian, . . . , English]

2. UNITS: selection of the type of unit of measurement to use.

[Metric (Km/h, ha, etc.) - Imperial (mph, A, etc.)]

3. DATE and TIME: Date and time of the system

4. BACKLIGHT: display backlight intensity

adjustment

[20-100%].

5. BUZZER VOLUME: buzzer volume adjustment.

[20-100%]

6. DIMMER: automatic "day" to "night" switching mode can be scheduled and vice versa, the two modes are designed to optimise visibility during the day and not to excessively disturb the operator during evening or night work.

7. SOFTWARE UPDATE: VT software update.

8. ECU CONFIGURATION: this function enables to configure the association of the rows to be excluded and the outputs of the

isolator control units (art.10CEN-0010).

4.2.2 Menu

This programming phase can be accessed at any time during the task by pressing the menu key for 3 seconds: displaying the main parameters currently programmed (not modifiable). Pressing the same key again will actually access the programming menu. The parameters that compose it are defined

below:

WORKING MODE: The operating mode defines how the sowing distance and population are calculated and checked. The Dorado MX3 kit allows the operator to choose between COUNTER and PASSAGE mode.

COUNTER mode: the kit calculates and checks the sowing distance and seeding population for every row, counting the pulses coming from the seed sensors; this operating mode is recommended for work with medium/large sized seeds (e.g. corn, beetroot, soybean)

PASSAGE mode: the kit limits itself to checking the presence of pulses coming from the seed sensors, calculation of the sowing distance or seeding population is NOT calculated. This operating mode is recommended for work with small seeds (e.g. rapeseed, vegetables);

COUNTER MODE MENU: defines the seeding population and density calculation parameters according to counter mode.

PASSAGE MODE MENU: sets the seeding population and density parameters

according to passage mode.

GPS MENU: submenu currently not implemented.

SENSORS MENU: manages the operating and management parameters of the various system operation sensors.


Dorado MX3 kit

39

INTERROWS DISTANCE: Program the width between the rows in cm (or inches); this data is important both to calculate the area being worked on and to calculate the sowing distance and population. The Dorado MX3 Kit automatically calculates the operating width, multiplying the interrows width data by the number

of seed sensors acquired at start-up;

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

The most external rows detected are number 1

and number 12, therefore the calculated

work width will be:

interrows width X 12



work width will be:



Dorado MX3 kit

40

SUCTION MENU: allows you to enable and disable the monitoring of the operating threshold of the vacuum gauge sensor and the respective alarms.

RPM MENU: enables and disables RPM sensor minimum and maximum threshold monitoring and the respective alarms.

DIAGNOSTICS MENU: submenu currently not implemented.

RESERVED MENU: the screens contained in this sub-menu are protected by a password that must be entered on a screen that appears when said screens open.

Once the password has been entered correctly, the settings we will edit are

necessary to adapt the system to the machine on which it is installed.

work width will be:



Dorado MX3 kit

41

4.2.2.1 Counter mode menu

The following parameters can be set

in this menu:

• SEEDING DISTANCE: program the reference sowing distance (valid only for COUNTER operating mode): the kit will associate this with the 100% reference value as a reference for the signalling of alarms on seed sensor inputs. Setting the parameter to "Auto" activates the reference sowing distance auto-calibration function.

Automatic mode is enabled by setting the

"Sowing distance" = auto.

Once automatic mode is activated, the Dorado MX kit calculates the reference sowing distance once on start-up: each time the machine work parameters are changed (change, selectors and/or discs), the Dorado MX kit must be turned off and on again before starting operations.

!

Attention

The automatic mode enables the

Dorado MX kit to adapt to the effective

working conditions of the machine. However, if the machine is not configured correctly for the type of work it wants to do, or if one or more

sowing elements does not

work correctly, the work may be incorrect!

MC Elettronica declines all

responsibility deriving from use of the machine in automatic mode that is not

perfectly operational, incorrectly configured and incorrectly

maintained.


Dorado MX3 kit

The sowing distance calculation is carried out in the first 10 metres, regardless of the speed reached, and the value of reference is then adjusted more accurately within a few seconds; for example, to sow corn at 6Km/h, approximately 5 seconds are required; a higher speed or with denser sowing, the time is shorter.

N.B.: for correct operation in automatic mode, it is recommended to install a speed sensor to detect a minimum of 1.8 ÷ 2 pulses/m (330 feet) – also refer to chapter 4.2.2.3 Sensors Menu on page 44

• POPULATION: program the reference seeding population (only valid for COUNTER operating mode): the kit will associate this to the 100% reference value as reference for alarm signals on seed sensor inputs;

• DISC HOLES NUMBER: allows you to define the number of holes on the seeding disc;

• ALARM THRESHOLD: program the alarm threshold in percentage (valid only for COUNTER operating mode): this percentage is referred to the sowing distance and seed life values programmed;

for example: if you program population of 10.0 seeds/m2 and a 25% alarm threshold, this means that the rows in which the seeding population detected is less than 7.5 seeds/m2 (10.0-25%) or greater than 12.5 seeds/m2 (10.0+25%) will be signalled with an alarm on the VT;

• ALARM DELAY: program the time delay between the visual signalling of the

alarm (histogram in red or cell in red) and the audible one (buzzer);

• ALARM TIME: program the duration of the audible alarm;

• ROW SCANNING: in counter operating mode, the two main fields at the top in the VT screen indicate sowing distance and population values, scanning the

various rows for the time programmed in this parameter;

• STABILITY OF VISUAL.: In the counting work mode, the display stability can be increased or decreased; the higher the set value, the more stable the display will be, that is, only the more serious errors will be indicated. If the set number is low, the display will be less stable and minor errors will also be indicated.

4.2.2.2 Passage mode menu

Figure 31

The following parameters can be programmed in this menu:

1. WARNING DELAY: In passage mode, the sowing alarm sounds when a pulse is no longer detected for the time programmed in this parameter; for example: programming this parameter at 3.0 seconds, the sowing alarm sounds if one or

more seed sensors do not send pulses for at least 3.0 seconds.

2. ALARM DELAY: Program the time delay between the visual signalling of the alarm (histogram in red or cell in red) and the audible one (buzzer)

3. ALARM TIME: Program the duration of the audible alarm

1. SPEED SENSOR: It is possible to program the number of pulses coming from the speed sensor every linear metre (or 330ft) covered by the machine; you can enter the parameter manually via manual Calibration. Assuming that the speed sensor is located so as to detect 4 pulses for every seeder wheel

revolution.

4. SENSOR DIAGNOSTICS: In this menu you can check the electrical wiring of various sensors, even when the machine is stopped. The screen shows all the available sensor types and the information displayed corresponds to the status of the sensors themselves, for example: by placing a metal reference in front of the speed sensor, it will go from "OFF" to "ON" and vice versa when the metal reference is removed. For the seed and fertiliser sensors, moving an obstacle (a finger or a screwdriver) in front of the sensor's optical parts, one at a time, you will see the numbers on the display corresponding to the sensor tested; furthermore, moving the black selection bar with the UP and DOWN keys, the

VT will emit an audible signal when its sensor moves from "OFF" to "ON".

9. Alarms

The alarms are always displayed based on the priority of the message. They are following by a modulated audible signal to get the operator’s attention regarding

the problem that is then displayed on the screen.

When an alarm is generated in the Dorado MX3 kit, it can be due to various parameters that the system monitors during machine operation. The sensitivity, duration and tolerance threshold are defined in the specific programming menus

described in paragraph 4.

The events that generate an alarm are listed below:

• The operating mode set to “Counter” allows us to make sure that the sowing distance and the seeding population correspond to the values the operator wants. Instead, if set to “Passage”, the system verifies whether the seed passes within a certain interval.

• The Dorado MX kit allows you to indicate the non passage of the seed from a set time data.

Additional alarms will be available in future implementations.

10. Maintenance

This chapter gives instructions on how to carry out routine and special maintenance.

Routine maintenance refers to those operations which must be carried out periodically. As they do not require specific skills, they can be carried out by the users (operators, etc.).

Special maintenance refers to unforeseeable operations due to mechanic or electric failures. They require specific technical skills, so they should be exclusively carried out by qualified personnel (maintenance personnel etc.).

10.1 Routine maintenance

Routine maintenance consists in cleaning the instrument.

Clean the instrument with a wet cloth and mild detergent to avoid erasing the serigraphs on the panel.

!

Warning

• Do not use pressurised water jets.

• Do not use abrasive products, solvents or alcohol.

• Do not use hard pointed objects to press on the keyboard.

10.1.1 How to protect the main connector

If the monitor is not used for a long time, disconnect the main signal connector from the wiring. We recommend isolating both connectors (of the monitor and of the wiring harness) with Nylon. If they are not disconnected, no protection is needed.
