2. General description
The MCK 800 monitor is multifunction electronic instrument suitable for small
precision drills, pneumatic or mechanical control of sowing “monogerm” (corn,
soybean, sunflower, sugar beet, etc.)
The instrument controls the operation of the file indicating the LCD by horizontal bars,
any abnormality of sowing.
During the working cycle, the following data are displayed and controlled:
 the width (width - PROG);
 the 'working area: total and partial (Ha);
 the status of files;
 the hours worked on.
The computer carries out the above-mentioned operations by means of a series of
photocells installed on each single row of the seed drill for seeds counting, and a
speed sensor to be installed on a wheel of the machine.

 Connect the signal cable to the junction box (B) placed on the seed drill;
 connect the speed sensor (VEL) and the photocells (D);
 connect the supply cable (F) of the Computer to the battery of the vehicle;
connect the RED wire to the positive pole (+) and the BLACK wire to the
negative pole (-).
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.
!
Warning
We recommend to protect the sensor cable with a rubber sheath.

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.
