2. General description
The MCK 3000 Control Area is a universal hectare counter that can be installed on
any type of agricultural machine. With this instrument the following parameters can
be monitored:
•partial worked area;
•total worked area;
•distance travelled;
•speed (Km/h);
•forecast of the hectares that will be worked in an hour (only visible while you are
working).
The Monitor uses a speed sensor to carry out the functions described above, which is
to be installed on the machine wheel, and a mechanical counting sensor or a seed
sensor.

3.1 Mounting the Monitor
To assemble the instrument operate as follows:
•on a flat surface inside the cabin of the vehicle, drill 2 holes (D. 9 mm)
aligned with those on the bracket (Figure 33 - ref. <A>) and, by means of
two screws (not supplied), securely fasten the bracket to the structure;
•fasten the Monitor to the bracket by screwing the supplied knobs (Figure 33
- ref. <B>) in the holes on the sides of the Monitor (Figure 33 - ref. <B1>).
N.B.:
we recommend installing the Monitor in front of the operator to make it
easier to use during the working cycle.

3.2 Sensor installation
The MCK 3000 Area Control can be equipped with 3 types of sensors:
•speed sensor (always present);
•mechanical counting sensor (for NON self-levelling combine harvesters, tractors,
etc.);
•reflection seed sensor (for self-levelling combine harvesters).
3.2.1 Speed sensor installation
You can install the speed sensor anywhere there is mechanical movement, on the
wheel (front or rear) of the agricultural machine/vehicle or by creating a metal
reference protruding by at least 7 mm ( Figure 4 ref. B2). We recommend installing
the speed sensor inside the wheel and placing the sensor head opposite the rim bolts
(Figure 4 –ref. A and B).
Set the gap between the sensor and the bolts at about 2/3 mm (Figure 4 –ref. B1).
Firmly fix the sensor bracket (supplied) to a secure part of the machine. Fix the
sensor to the bracket with the nut and the lock nut.
!
Warning
The sensor cable should be covered with a rubber sheath.

3.2.1.1 Automatic calibration of the “C” parameter
Parameter “C” is automatically set by covering a fixed distance of 100 metres,
according to the following procedure:
▪With the Monitor on, press the key several times until the arrow on the
display lights up as shown in the figure: ;
▪press keys and simultaneously: 0 0 will appear on the Monitor;
•cover 100 metres and the display will show the pulse count (1..2..3, etc.); once
the 100 metres are covered, confirm with the key.
N.B.: it is recommended to perform the operation at least 2 times in a row, checking
that the detected value is always the same 1 pulse. If the difference is
greater, it means that the speed sensor is NOT positioned correctly.
Therefore, the assembly must be checked (see Figure 4)

MCK 3000
3.2.2 Installing the mechanical counting sensor (if present)
The mechanical counting sensor is used if the monitor is installed on a standard
combine harvester. It can be secured to the lower part of the bar so that when this
lowers, the spring is released and the hectare count begins (parameter “Ct” = A, as
factory-set) (see Figure 5 –ref. A2).
!
Attention!
Adjust the trip point of the switch by changing the number of links in the
chain.
Figure 5. Installing the sensor in the lower part of the bar.
If necessary, the switch can also be secured to the upper part of the bar, by setting
parameter “Ct” = C (see chapter 5, “Programming work parameters”). This way, when
the bar is lowered, the spring is tensioned, and the hectare count begins (see Figure
6 –ref. B2).
Figure 6. Installing the sensor in the upper part of the bar.

Warning
The sensor cable should be covered with a rubber sheath.

3.2.3 Installing the reflection seed sensor (if present)
The seed sensor is used if the monitor is installed on a self-levelling combine
harvester.
Secure the seed sensor in a stable way on the right or left side of the pipe, using the
bracket (supplied) with the lens facing the ground, and the optical axis perpendicular
to the ground, at a distance of no more than 1.10 metre (see Figure 7).

Warning
The sensor cable should be covered with a rubber sheath.

3.2.3.1 Adjusting the sensitivity of the seed sensor
After installing the seed sensor, proceed as follows to adjust its sensitivity:
1. Check that the sensitivity
adjustment trimmer (A) is turned to
the extreme hourly position;
2. Turn the monitor on. The RED LED
(B) must be on; otherwise,
enhance the orientation or move
the seed sensor closer.
3. Turn the trimmer (A) very slowly
clockwise until the LED (B) turns
off.
4. Turn the trimmer (A) again
clockwise by a few tenths of a
degree for optimal adjustment.

5.4 Setting the hectare count mode
Set the hectare count mode by turning the instrument on ( key) and simultaneously
pressing the and keys until parameter “Ct” appears on the display
followed by a message indicating when the monitor will count the area.
The count mode can be changed with the and keys; consider the type of
isolator used when setting it: either a simple switch that opens and closes a contact
(count magnetic sensor), or an electronic signal (seed sensor).
You can set:
Ct = A
: the Monitor will only count the area when the contact that acts as an isolator
will be OPEN;
Ct = C
: the Monitor will only count the area when the contact that acts as an isolator
will be CLOSED;
Ct = FA
: the Monitor will only count the area when the seed sensor will emit the
“free” signal (no objects in front of the lens);
Ct = FC
: the Monitor will only count the area when the seed sensor will emit the
“blocked” signal (objects in front of the lens).

5.6 Check the speed sensor operating
Check the functioning of the speed sensor as follows:
1. Turn the monitor on ( key);
2. Repeatedly pass in front of the red part of the sensor using a screwdriver or
other metal mass. If the computer displays the simulated speed (which probably
will not be constant) it means that the sensor is functioning and is properly
connected.
5.7 Check that the mechanical counting sensor functions
Check the operation of the mechanical sensor as follows:
1. Turn the monitor on ( key);
2. Select the partial/total hectare display ( key);
3. Pull the sensor chain so as to close the contact (or vice versa, depending on the
mechanical position);
4. Check that the display flashes when you do not want the area to be increased.
5.8 Check that the seed sensor functions (if present)
Check the operation of the photocells as follows:
1. Turn the monitor on ( key);
2. Use the hydraulic controls on the machine to raise and lower the bar, making
sure that the display flashes when the counting is stopped (raised bar).
