2. General description
The SOLID CONTROL MCK 2000 electronic control is designed for application on
dual-fan centrifugal fertilizer spreaders, and its main purpose is to adjust the
distribution concentration of the product.
The control performs its function using two electric motor-actuators, which regulate
the opening and closing of the fertiliser distribution slits. The SOLID CONTROL
foresees the adjustment of the concentration both automatically with DPA system,
and manually through operator management. It is possible to differentiate the
concentration by areas, by varying the flow of product flowing to the rotating discs.
The monitor uses the LCD display, back-lit for night vision, to display the following
quantities:
Product concentration in Kg/ha;
Total quantity of distributed product expressed in Kg;
feed-rate of the tractor in Km/h;
Partial area worked in ha;
Total area worked in ha;
Rotating speed of the PTO in RPM;
working hours.
On request, the monitor can equipped with an optional RS 232 serial port to which a
specific printer can be connected or communicate with other equipment that use the
same communication standard (to be agreed with the MC Elettronica Technical
Department).

3.2 How to install the sensors
The SOLID CONTROL MCK 2000 can be equipped with 3 types of sensors:
Inductive sensor for detecting the feed-rate code 481 (always present);
Inductive sensor for detecting the speed of the PTO code 481 (always
present);
grain level sensor code 1403 (optional).
3.2.1 How to install the inductive speed sensor D.18 item 481
The inductive sensor can be installed wherever a mechanical motion exists, on the
(front or rear) wheel of the agricultural machine/vehicle or otherwise creating a
protruding piece of metal for reference, long at least 7 mm (Picture 5 –ref. <C>). We
recommend installing the speed sensor inside the wheel and placing the sensor head
opposite the rim bolts (Picture 5 –ref. <A>).
Set the gap between the sensor and the bolts at about 2/3 mm (Picture 5 –ref. <B>).
Firmly fix the sensor support (supplied) to a secure part of the machine. Fasten the
sensor to the bracket using the nut and the lock nut.
!
Warning
The sensor cable should be covered with a rubber sheath.

3.2.2 How to install the inductive sensor for PTO D.18 item 481
The PTO sensor can be located next to the PTO socket where an adaptor (not
supplied) is fitted. This comprises a circular bushing, secured with at least 2 bolts,
placing the sensor head in front of the bushing bolts (Picture 6 –ref. <A>) : in this
way the sensor picks up two bolts every rotation of the power takeoff.
Set the gap between the sensor and the bolts at about 2/3 mm Picture 6 –ref. <B>).
Firmly fix the sensor support (supplied) to a secure part of the machine. Fasten the
sensor to the support by means of a bolt and a lock nut.

3.2.3 Installation of product level capacitive sensor (if present) code
1403
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 seed tank Picture 7 - example 1) by
means of a clamping bracket (not supplied) or it can be directly fixed on the tank
body (Picture 7 - example 2) and fastened with a bolt and a lock nut. The red part of
the capacitive sensor MUST touch the product: so, by positioning the sensor head in
correspondence of the reserve limit, when the sensor is covered by the product
(Picture 7 - ref. <1> examples 1 and 2) DOES NOT SEND the alarm signal, but if the
sensor head, while working, remains uncovered (ref. <2> examples 1 and 2 Picture
7) the corresponding acoustic (buzzer) and visual ( ) alarms will be activated

3.3 How to install the actuators
Actuators are installed according to the set-up of the machine. In whatever set-up
they must regulate the opening and closing of the slits through which the product
passes.
The optimum installation is obtained when the following conditions apply:
1. The entire piston length is used to open/close the slits, without “dead areas” at
the start or finish: this means that for every piston movement the quantity of
fertiliser varies;
2. the ratio between the piston stroke and quantity of product passing through the
slits is linear (e.g. when the actuator piston is at 40% of its maximum stroke,
40% of the maximum quantity of fertilizer should be distributed).
The SOLID CONTROL MCK 2000 can be fitted to any machine. See paragraph “How
to adjust the actuators” on page 16 and overleaf.
You can install a third motorised actuator (optional) on the machine for handling a
deflector panel useful in the treatment phases on the field border.

3.3.1 How to adjust the actuators
When installing the SOLID CONTROL MCK 2000 for the first time, it is important to
calibrate the actuators to enable them to work properly. The factory settings are
made so that the actuator pistons are fully extended when the slits are completely
open (max. distribution of product, Picture 8 - ref. <A>) and are fully withdrawn when
the slits are closed. If the specific application requires the opposite set-up (pistons
withdrawn with slits open (Picture 8 - ref. <B>), the “Mot” parameter should be
changed as follows:
Switch on the Computer (“ON/OFF” switch) holding down the key until the
“Mot” parameter is displayed (keep holding for about 20 secs.);
Using the and keys, select <0> if the actuators work ion standard set-up,
and <1> if they work in the opposite set-up;
Picture 8
Once the set-up has been established, the actuators can be set (when the
machine is switched off).
N.B.:
if actuators are supplied by MC elettronica, the following procedure was
already carried out by the factory.
A Mot = 0
B Mot = 1

3.3.1.1 Calibration procedure
1. Switch on the Computer with the ON/FF switch (Picture 9 - ref. <A> on page 18)
and select MANUAL with the key: the red “MANUAL” LED comes on
2. Switch to “ON” the “MAIN”, “LH” and “Rh” switches (Picture 10 - ref. <G>, <H>
and <P>);
3. Use the “+/-“ switches on LH and RH (Picture 9 - ref. <I> and <O>) to move the
pistons to about half-way along the stroke;
4. Without touching the other switches, switch off the Computer, using the
“ON/OFF” switch (Picture 9 - ref. <A>);
5. With the Computer off switch <G>, <H> and <P> to the “OFF” position;
6. Switch on the Computer and hold down the key until “CAL” is displayed; the
Computer moves the left-hand actuator piston to the limit switch position (make
sure the slit is fully open);
7. After a few seconds a value between 920 and 1022 is displayed. At that
moment, the Computer will close the left actuator piston fully. Then a value
between 1 and 100 is displayed.
8. The procedure described in the previous point is then carried out for closing the
right actuator.
9. if the 4 readings on the display when the left-hand (LH) and right-hand (RH) slits
open and close are in the above ranges (9201022, 1100, 9201022, 1100)
the actuators have been fitted properly. If not, the actuators were NOT supplied
by MC Elettronica and the functioning of the Computer is not guaranteed
(contact your nearest MC Elettronica dealer).
