Descripon of the A100 control system for seed drill
The device is designed for installaon into all types of seed drills. All important data on the drill operaon and
its sengs are at disposal for the user via a tablet in the tractor cab.
The A100 control system offers the following functions:
• Automac or manual creaon of tramlines
• Pre-emergent marking of tramlines
• Indicaon of minimal level of seed in hoppers, 2x
• Assembly travel speed measuring
• Actual date and me
• Fan speed indicaon
• Seeding mechanism speed indicaon
• Daily hectare measuring
• Summary hectare measuring
• Automac seeding test
• Seeding mechanism driven by a motor – up to 4 motors
• Connuous regulaon of the seeding dose during sowing
• Drill lighng control
• Drill hydraulic funcons control – up to 20 funcons
• Scanning of seed passage in each seeding hoses – up to 128 sowings

Controlling the A100 system:
The display unit is controlled via the colour touchscreen of the tablet. Pressing of a key is indicated by an
acousc signal.
Displaying structure of the A100 system:
The controlling of the system is divided into two basic screens.
Screen No.1: Displays all important data on the operaon of the seed drill which are necessary to monitor
during the sowing process and enables to change the parameters of the tramline, seeding
dose, fan speed limits, doser 1 and doser 2 seeding dose, all this during the course of the
operaon.
Screen No.2: Serves for the user to input the parameters of the seeding test for dosers 1 to 3, the number
of seeding sensors and their sensivity, the C-factor for the travel speed inducon scanning
and mes for the hydraulic funcons. It also comprises the control of the lighng, subsoilers,
mulching secon and seng of markers automacs.

Screen No.1:
Description of the screen No.1:
1.1 Assembly travel speed
Displays the actual travel speed of the seeding assembly based on the signal from the
GPS/Glonass, radar or induction sensor impulses.
In case of usage of the:
• inducon sensor, it is necessary to adjust it correctly. The distance of the M12 indu-
con sensor from the scanning rosee must be 4 mm maximally. If the sensor is co-
rrectly adjusted, its signalling LED must light on every me the rosee metallic tooth
passes around the sensor. In case of an incorrect adjustment, some impulses are
skipped which leads to inaccurate travel speed measuring. This will cause inaccuracy
of the sown dose and reading distoron of the hectare-meter.
• radar, it is necessary to install it so it will not be affected by e.g. the rotang wheels
of the tracle machine (e.g. a tractor) or by a large cloud of dust or other solid parc-
les flying offof the tractor wheels or the seed drill itself. This will again cause increa-
sed inaccuracy of the sowing and hectare-meter values.
• GPS/Glonass, the antenna must be installed at the highest point of the drill and must
not be shaded by any metallic cover. Unless the antenna direct visibility into the sky
is ensured, the GPS system will operate incorrectly and the drill will not react to the
movement, conngently a non-zero speed could be measured due to the poor signal
even in case the drill is at standsll (e.g. when parked under a hall roof).

1.2 Fan speed
Displays the actual value of the fan speed. In case the fan speed value drops under a set
value, the icon will turn red and an acousc signal will sound. To set the speed limit, pre-
ss the fan icon and change the speed value aer the numerical entry dialogue appears.
Confirm the sengs by pressing the OK key.
1.3 Daily hectare-meter
Displays the actual state of the sown area up to a maximal value of 99.9 ha. The dis-
played value can be reset by shortly pressing the daily hectare-meter indicator.
1.4 Summary hectare-meter
Displays the total sown area. This value cannot be reset by the user. Reseng is possible
only by a service intervenon.
1.5 SH1 and SH2 sensors of seed level in hoppers
Displays the actual state of seed in the hopper. When the seed level drops below the
level of the sensor fied in the hopper, the empty hopper symbol will turn red and an
acousc signal will sound.
1.6 Level sensors adjustment
On the sensor rear side there is a small screw under which the adjusng screw of the
sensor sensivity is located.
1.7 A1 sensor of seeding
Displays the actual state of seed passing to the seeding hoses.
• In case the seed is passing through the seeding sensor, a green box symbol is dis-
played in the corresponding posion.
• In case the seed is not passing through the parcular sensor, a yellow box symbol is
displayed in the corresponding posion.
• In case the sensor is not connected, is not communicang or it is faulty or damaged,
a red box symbol is displayed in the corresponding posion.
1.8 Actual date and time
Displays the actual me. The me is set automacally according to the tablet system
me and is corrected by the GPS/Glonass signal during the operaon. In case the GPS/
Glonass signal is unavailable, the me is synchronized with the tablet me upon the
entry into the second screen.

1.9 Night and day mode change
Pressing the display in the date and me displaying area will invoke the night mode
display which is less highlighted and does not disturb during work at night. Pressing the
same area again will return the day mode display.
1.10 Seeding mechanism speed
Displays the actual value of seeding mechanism speed during the drill operaon. The
speed range is within a scale of 0 rpm to 255 rpm. The maximal speed range is given by
the manufacturer and is derived from the width and the maximal travel speed of the
drill. In case the seeding mechanism stops during drill operaon, a zero speed value is
displayed and an acousc signal is sound to alert the operator about this serious fault.
In case the speed value is lower or higher than the required speed, the speed numerical
value is highlighted in red and an acousc signal is sound. This signals to the operator
that he must either reduce the seeding assembly travel speed or stop the drill and check
the seeding mechanism for possible faults. To manually stop the doser, press the
speed numerical value. By this, the STOP symbol will be displayed instead of the speed
value and the doser motor will be blocked during driving. By pressing the STOP symbol,
the doser motor will return to the standard operaon mode.

1.11 Setting and displaying the tramline
This secon of the screen is intended for displaying and seng all data related to the
tramline creaon.
The first key on the top and in the middle of the screen represents the seed drill width
seng. To set a value, press this key and set the required width of the seed drill by me-
ans of the numerical dialogue.
The second line is for seng the sprayer width. The seng is carried out as descri-
bed above. Aer seng the sprayer width, the number of tramline rides is automa-
cally calculated and displayed. Also the permied sides of sowing start are displayed.
The permied sides are highlighted in green and the unpermied sides are in grey.
Select any of the permied (green) sides of sowing start by pressing it and its colour will
change to yellow. The sowing sides can be changed anyme. In case a non-exisng com-
binaon of the seed drill and sprayer widths is set, the number of rides is calculated as
zero and all sowing sides are highlighted in grey. The tramline sengs and the state of
the counter are stored in the internal memory of the unit even aer turning the system
off. Aer turning the feeding power on, all data are set to the state as they were before
turning off.
1.12 Tramline automatic mode
The tramline creaon is displayed as two strips in the middle of the screen boom side.
If the strips are uncoloured, the tramline is not created. If the strips are colored, the
tramline is created.
Aer pressing the tramline symbol, the STOP symbol will be displayed across both stri-
ps. By this, the tramline creaon is manually stopped. The funcon is enabled by pre-
ssing it again. This is useful when it is necessary to drive around obstacles. With the
STOP symbol displayed, the tramline rides counng is blocked.
1.13 Tramline manual mode
Shortly pressing the tramline key will manually add up one ride. By pressing it for a lon-
ger me, the tramline counter is reset to the default state, i.e. to 1.

1.14 Pre-sowing function
Pre-sowing is a funcon that ensures rotaon of all dosers for about 7 seconds while
the drill is stopped. This enables to sow places which cannot be sown during driving,
e.g. a place where it is necessary to reverse-drive first, turn the pre-sowing on and
then drive forward. Press the START key to start the pre-sowing. Pre-sowing is accom-
panied by an acousc signal during the whole me the funcon is in operaon. Aer
the assembly is set in moon, the dosers automacally switch to the regulaon mode
according to the assembly speed.
1.15 Seeding dose
The combined round indicator states informaon on the set seeding dose in kilograms
per hectare. This value can be changed by tapping on the numerical value of the see-
ding dose, changing the value in the dialogue window and pressing the OK key. When
changing the value during driving, the speed of the dosers motors is changed based on
the new dose value.
Based on your actual need, you can also add or reduce the dose anyme during opera-
on.
Controlling the drill hydraulics:
1.16 Hydraulics turning on and off
Pressing this key will turn on all hydraulic controlling funcons. In case the hydraulics
are not turned on, none of the hydraulic funcons controlling keys will be funconal. By
pressing the key again, the hydraulics controlling funcons are turned off.
1.17 Drill unfolding
Pressing this key will start the drill unfolding funcon which will be in operaon for
a pre-programmed me. During the pre-programmed me, the drill remains unfolded
and aer the me elapses, the funcon will automacally turn off.
1.18 Drill folding
Pressing this key will start the drill folding funcon which will be in operaon for a pre
-programmed me. During the pre-programmed me, the drill remains folded and aer

Pressing this key will turn on the drill raising funcon which will start the raising from
sowing for a pre-programmed me. Aer raising, the funcon will automacally turn
off.
1.23 Info bar
This symbol represents the wireless connecon with the control unit via BLUE-
TOOTH. If the symbol is not yellow colored, the tablet is disconnected from
the control unit and it cannot be controlled. The following noce is displayed
on the tablet:
This symbol informs the user that the GPS/Glonass signal is available. In case
the drill is equipped with and controlled by the GPS/Glonass, it is necessary to
wait unl the symbol turns yellow before starng work.
!Unless the symbol is highlighted in yellow, the speed measuring, hectare
counng and the regulaon of dosers motors will be blocked!
