SEEDER MAT MCK 2500 SX
2. General description
The SEEDER MAT MCK 2500 SX is a multifunction electronic computer designed to
be used on pneumatic or mechanical seed drills.
Its main function is to automatically shut off certain seeding rows in order to a leave a
non-sown row to be used as a “path” for the subsequent passage of the sprayer.
In addition, the computer can process the signals arriving at two inputs that can be
used to control the rotation of the turbine and of the distributor. The computer can be
programmed to warn the operator by means of an acoustic alarm or a visual alarm
when one or both these devices are turning too slow or have stopped (HOWEVER,
THE DISTRIBUTOR RPM IS NOT SHOWN ON THE DISPLAY).
During sowing operations the display can show the following readings:
 travel speed (km/h)
 hectares sown, through 2 independent counters (total and sub-total)
 linear distance travelled
 turbine RPM
For information on how to program the alarms see chapter 5 “Programming” on page
21.
The computer performs these functions by means of the following sensors: an
inductive speed sensor, which should preferably be installed on the machine’s wheel
axle; an inductive sensor that measures the turbine RPM; a capacitive sensor to be
installed in the seed tank to measure the seed level; a third inductive sensor to
measure the distributor RPM; finally a magnetic sensor to be installed on the arm of
the row marker disc or on the machine’s lifting point (see paragraph 5.6) when
leaving un-sown “paths” (tramlines).

3.1 How to install the computer
To install the computer proceed as follows.
 Drill a Ø9 mm hole on a flat surface inside the cab and fasten the supporting
bracket by applying a screw (not supplied) into the opening (A) on the bracket.
 Fasten the computer to the bracket using the two knobs on the sides (ref.
<B> Figure 2 )
N.B.: We recommend installing the computer in front of the operator to make it
easier to use during sowing operations.

 Plug the connector of the magnetic sensor of the row marker disc (code 00SEN-
1402) into the “Disc” connector (A) on the seed drill.
 Plug the connector of the inductive travel speed sensor (code 1404) into the
“Speed” connector (B) on the seed drill.

 Plug the connector of the inductive (or magnetic) distributor RPM sensor into the
“Fan” connector (D) on the seed drill.
 Plug the connector of the capacitive seed level sensor (code 1403) into the
“Level” connector (E) on the seed drill. Note: If you do not plan to use the seed
level alarm function BUT you still want to use the other warning functions, the
connector (E) on the wiring harness must be fitted with a jumper, available on
request (code 00SEN-JUMPER3VF-0001).
 Connect the “Left Motor” (F) and “Right Motor” (G) cables to the shut-off
devices on the seed drill. Different kinds of wiring harnesses are available
depending on the type of shut-off devices installed. The table below shows the
harnesses corresponding to different shut-off devices. If you are using the
specific MC Elettronica shut-off valves, you only need to plug the connectors on
the valves into the connectors on the harness. If you are using another kind of
motorized shut-off valves, connect cables (F) and (G) directly to the wires on the
valves, which should be provided with a suitable connector. If you are using
solenoid valves, cables (F) and (G) will be fitted with DIN connectors, so you can
simply plug the connectors directly into the solenoid valves.

 The harness on the MCK2500SX computer is provided with an additional cable,
ref. (X) “Actuator”. The contacts on this cable are normally under a voltage of
+12VDC. During sowing operations, when the computer activates the shut–off
devices on the right-side rows or on the left-side rows or on both sides to create
a “path”, the polarity on the (X) cable is reversed and becomes –12VDC.
Therefore, if necessary, cable (X) can be connected to a third electric motor
(max. 12V 2A) operated through a by-pass: every time at least one row shut-off
device is activated, the motor connected to cable (X) is also activated. N.B. If this
function is not required, insulate the connector on the cable (X) with a sheath or
with insulating tape.
 Connect the power cable (H) (delivered in the box containing the computer)
directly to the vehicle’s 12VDC battery. Connect the RED wire to the positive
terminal (+) and the BLACK wire to the negative terminal (-). DO NOT use
cigarette lighters or similar devices as connectors.

3.2 How to install the sensors
The MCK 2500 SX computer is provided with 3 kinds of sensors:
 inductive or magnetic sensors (Ø12 or Ø18) for measuring speed, turbine RPM
and distributor RPM (code 1404)
 a magnetic sensor (Ø12) for the row marker (code 00SEN-1402)
 a capacitive sensor (Ø18) for measuring the seed level (code 1403)
3.2.1 How to install the Ø18 speed sensor – code 1404
You can install the speed sensor anywhere there is mechanical movement, on the
wheel (front or rear wheel) of the agricultural vehicle/machine or applying a metal
reference protruding by at least 7 mm (Figure 4 – ref. <C>). We recommend installing
the speed sensor inside the wheel and placing the sensor head opposite the rim bolts
(Figure 4 – ref. <A>).
Set the gap between the sensor and the bolts at about 2-3 mm (Figure 4– ref. <B>).
Fasten the sensor to a fixed part of the vehicle/machine, so that it is firmly secured to
the structure. Fix the sensor in place using the nut and the lock nut.
!
Warning
We recommend protecting the sensor cable with a rubber sheath.

3.2.2 RPM sensor installation examples
The inductive turbine RPM sensor (and distributor RPM sensor, if present) (see
chapter “General description” on page 7) must be placed opposite a metal reference
having a diameter at least as large as the respective sensor (12 mm) and protruding
from any other metal body by at least 7 mm. The gap between the sensor and its
respective metal reference should be 2 to 3 mm.
The figures below show two different installation examples.

3.2.3 How to install the Ø12 magnetic sensor – code 00SEN-1402
Type 1 installation: The magnetic row marker sensor can be installed on the seed
drill on one of the articulated joints of a row marker disc arm. The corresponding
magnet (supplied with the sensor) can be placed on the row marker disc arm so that
the magnet is opposite the sensor when the arm is raised (Figure 7 – ref. <a>) and
moves away from the sensor when the arm is lowered (Figure 7 – ref. <b>).
Place the sensor so that when the row marker disc arm is completely raised the
magnet is parallel to the sensor, with a gap of 4-5 mm.
Fasten the supporting bracket (not supplied) securely to a fixed part of the seed drill
structure.
Fasten the sensor to the bracket using the nut and the lock nut.
N.B. The reference element should be as close as possible to the row marker disc
arm in order to avoid the arm’s oscillations causing false readings when the reference
comes close to the sensor during operations.
Type 2 installation: This is the same as above, except that the sensor and the
magnet come opposite each other only when the machine is raised or lowered.
Figure 7 shows an example in which the sensor and the magnet are opposite each
other when the machine is raised.
NOTE: The “disc” parameter must be set according to the type of installation
selected. See paragraph 5.6

3.2.4 How to install the Ø18 seed level sensor – code 1403
The capacitive seed level sensor should be installed where it can signal a warning
when the level in the seed tank drops below a predetermined minimum level. The
capacitive sensor can be installed inside the seed tank (Figure 8 - example 1) by
means of a support bracket (not supplied) or mounted directly on the tank body
(Figure 8 - example 2) and secured with a nut and lock nut. The red part of the
capacitive sensor must be in direct contact with the seeds. In this manner, with the
sensor head placed at the minimum seed level, when the sensor is covered by seeds
(ref. <1> examples 1 and 2,Figure 8) it emits NO alarm signal, but when the sensor
head is uncovered (ref. <2> examples 1 and 2,Figure 8) the system signals a low
seed level warning.
