2.2 How to install the sensors
The MCK 800 Computer is equipped with 2 types of sensors:
 speed sensor (always present) cod. 481;
 photocell sensor (always present) cod. 4228, 10FOT-1269, 10FOT-
SEMIMINUTI-0001.
2.2.1 How to install the speed sensor D.18 cod. 481
You can install the speed sensor (cod. 481) anywhere there is a mechanic
movement, in the wheel (front or rear wheel) of the agricultural vehicle/machine, or by
making a metal reference which sticks out of at least 7 mm (Figure 1 – ref. <C>). We
recommend to install the speed sensor inside the wheel, by placing the head sensor
opposite the rim bolts (Figure 1 – ref. <A>).
Adjust the distance between the sensors and the bolts to about 2/3 mm (Figure 1 –
ref. <B>).
Fix the sensor holder bracket (supplied) to a fixed part of the vehicle/machine so that
it is well fixed to the structure. Lock the sensor to the bracket with the nut and lock
nut.

2.2.2 How to install the photocells
Photocells must be placed on each single row of the seed drill close to the seed-drop
area; if seed drills with seed-drop pipes are used, photocells must be placed at about
half the length of the pipe.
To install photocells, proceed as follows:
 distribute the photocells cables on the seed drill air pipes, respecting the row
numeration (Figure 2);
 fix the junction box (A) at the centre of the seed drill with some clamps held to
the machine;
 install the photocells taking into account the references of the sowing element
(reported on the technical sheet which is related to the type and mark of the seed
drill used, and enclosed with this manual).
!
Warning
make sure that photocells do not obstacle the seed-drop or the
mechanical functioning of the sowing element.

5. Using the Seeder Control MCK 800
1) Power on the monitor by pressing the “ON - OFF” key. The instrument will
perform for 1 second a brief test by activating the acoustic alarm and lighting
up all the display segments; after this test, working hours will be displayed
for 3 seconds.
2) To reset the totalizators (partial and total area worked in hectares), hold
down the corresponding key until the display views “0.00” (see picture 2).
To reset working hours, hold down any key for about 3 seconds while the display
visualizes working hours (after the initial test operated at the switching on). After
working hours, the monitor displays the rows which are operative as lit segments.
Segments which are off represent rows that are not checked by the monitor. When a
row does not sow regularly, the corresponding display segment starts flashing and an
intermittent audible alarm is given, which will sound for 5 seconds.
To display worked area and working width press the corresponding keys. The monitor
will display again the rows segments after 6 seconds.

6.2.1 Practical example for calculating the C parameter to be
programmed
As anticipated previously, in the “C” parameter you have to program the number of
impulses the proximity sensor has to send to the Tachometer every 100 linear meters
the machine works. Therefore, you must calculate how many reference points will
pass in front of the sensor every 100 linear meters. In this example we assume that
the proximity sensor is assembled so as to sense a magnet fixed to one of the wheel
bolts (see Figure 5):
 place the machine on a flat ground and mark clearly (with a piece of chalk, for
instance) the outer side of the tire in the exact place where it touches the ground
(figure 5 – ref. <A>);
 take as your reference on the ground a point that corresponds to the mark you
made on the tire (starting point. Figure 5 – ref. <A>) and move the machine
slowly forward until the wheel has made an exact number of rotations, for our
example let’s say 30, then stop the machine (end point. Figure 5 – ref. <B>); to
obtain highest precision of setting you’ll need to go at least 50 meters;
 measure the distance from the starting point to the end point;
 let’s assume the distance you measured is 60 meters: 60 meters divided by 30
rotations gives 2 meters as the measure of each rotation of the wheel;
 dividing 100 meters (reference distance for parameter “C”) by 2 meters (wheel
circumference) the result is that the machine wheel makes 50 rotations in 100
meters;
 now you only have to multiply the number of rotations the wheel makes in 100
meters (according to our calculation, 50) by the number of reference points the
sensor detects at each rotation of the wheel (according to our example, 1 bolt):
the result is the number of references/impulses that are detected per 100 linear
meters (according to our example: 50 x 1 = 50). Insert this value for the “C”-
parameter programming;
Parameter “C”= 100 metres x N° wheel references

6.3 Automatic calibration of “C” parameter
The automatic calibration of “C” parameter is effected by covering a fixed distance of
100 metres according to the instructions listed below:
1) Measure a distance of 100 metres on the ground and place the machine on
the starting point;
2) Display “C” parameter; press “+” (ref A) and „-“ (ref. C) keys simultaneously
to start counting (the display will be reset); release keys;
3) Drive along a way of 100 metres and stop after covering that fixed distance;
during the counting phase the display will show the number of impulses
received by the sensor;
4) Stop counting by pressing “width - PROG.” key (ref. B). The impulses
obtained will be automatically programmed in “C” parameter.
6.4 How to set the rows-alarm sensitivity
To program the rows-alarm sensitivity (values from 1 to 20) the monitor must be off.
Press B and C keys (see picture 1 page 12) simultaneously and hold them pressed;
at the same tome power on the monitor, and keep on holding B and C keys pressed
until „S-“ text is displayed, followed by the current sensitivity value; press C(-) or A(+)
keys to change the displayed value, while press and hold A key pressed for at least 2
seconds to store the desired value. From now on the monitor will start its normal
working cycle.
The sensitivity value which is to be programmed depends upon the type of sowing
effected; we advise you to program it as reported below:
MAIZE /SUNFLOWER BEETS SOYA SMALL SEEDS
Sen = 4 – 6 Sen = 6 - 9 Sen = 7 -12 Sen = 12 - 19

6.5 How to check speed sensor for functioning
Check the functioning of the speed sensor as follows:
1. Switch on the computer (<ON/OFF>-key);
2. Using a screwdriver or other metal mass, pass over the red part of the sensor
repeatedly. If the computer displays the simulated speed (which probably will not
be constant) it means that the sensor is functioning and is properly connected.
6.6 How to check photocells for functioning
Check the functioning of the photocells as follows:
 Simulated test:
With one of your fingers or with a small object, pass in front of each photocell: if the
photocell is correctly connected, it will send impulses to the monitor, which will
activate an audible alarm together with the switching on of the led corresponding to
the row.
After a few seconds the led will switch off and the audible alarm will go out. Repeat
the test with the next photocell.
N.B.: it is necessary to wait for the led to switch off again.
Execute this operation on each photocell.
 Real test:
If possible, execute a real test using the seeds that will be used afterwards; this will
guarantee a proper functioning while sowing.

7. Maintenance
This chapter gives instructions on how to carry out ordinary and extraordinary
maintenance.
Ordinary 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.).
Extraordinary 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.)
7.1 Ordinary maintenance
Ordinary 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 pressure water jets.
 Do not use abrasive products, solvents or alcohol.
 Do not press on the keyboard with pointed or hard objects in order
to avoid damaging the polyester film, thus endangering the
impermeability of the keyboard.
7.1.1 How to protect the main connector
In case of an extended use of the Monitor it is advisable to disconnect the main signal
connector (see Figure 1 on page 7) from the harness. It is advisable to insulate both
the connectors (of the Monitor and of the Harness) by using a Nylon protection.
If the connectors of the monitor and of the harness are NOT disconnected no
protection is needed.
7.2 Extraordinary maintenance
!
Warning
Extraordinary maintenance must be carried out by authorized personnel
only.
