10 Informationsaboutthecomputer
1.1 Manufacturer
AMAZONEN-Werke, H. Dreyer GmbH & Co. KG,
P. O. Box 51, D-49202 Hasbergen-Gaste/Germany.
1.2 AMADOS
The on-board computer "AMADOS" can be used as a
display-, monitoring- and controlling device
• for centrifugal broadcasters AMAZONE ZA-M,
• for AMAZONE seed drills
• as well as an hectare meter.
Themicro computer- theheart ofthe device- hasbeen
equipped with a memory and a lithium battery. All
entered and determined values are stores for approx.
10 years even if the on-pord power supply is switched
off.At thenextswitching onalldataareavailableagain.
1.3 Function description
"AMADOS"is supplied with a 6-digit display (1.1/1). In
operationg position of the corresponding machine the
display shows:
• at centrifugal broadcaster
current forward speed, spread rate and shutter
position "opened or shut".
• at the seed drill
current seed rate, tramline counter and marker
position
• as a pure hectare meter
the forward speed.
At the left hand edge of the display additionally 2
symbols are shown. The vertical arrow (1.1/2) shows
when the connected machine is in operating position.
The circle below (1.1/3) should flick during operation
andindicatesthatthesensorforcountingtheareaorthe
travelled idstance is transmitting impulses to the
"AMADOS”.
The key pad is offering 20 keys which are devided into
the following areas:
Red = Implement on/off
Green = Function keys (display of the
determined data).
Yellow = Input keys (entering the machine
data)
White = Keys that inform the calculator
about the change of entered orders

Arbitrary modifications to the"AMADOS" may resultin
damageandthereforethemanufacturerdoesnotaccept
liability for such damage.
In case of willful intent or gross negligence on the part
of the owner or a responsible employee, the
manufacturerisnot excempt fromliability.According to
the product liability law this excemption also applies in
casewhere liabilityis givenfor damageto personsor to
propertyonprivatelyusedgoodstheliabilityexcemption
of the supplier is void. It is also void in case properties
are missing which explicitly have been guaranteed
when the guarantee has just had the purpose to cover
the purchaser for damages which have not occured on
"AMADOS".
2.4 Safety advices
Before doing any repair work to the
electricalinstallation inparticularwelding
operationsonthetractororonthemounted
machine disconnect all electric couplings
to the "AMADOS".
2.5 Important hints for the use of the
"AMADOS" with the centrifugal
broadcaster or as a pure hectare
counter.
If a signal socket according to DIN 9684
standards exists on the tractor no additio-
nal sensor "X" (cardan shaft/wheel) need
to be fitted for determining the travelled
distance. The sensor "X" will then be
exchanged for a tractor specific adaptor-
cable (option). In case of an existing radar
sensor the signals can also be taken from
this socket.
IncaseofoperatingwithaUnimogwithout
the on-board-computer "UNICOM I" the
sensor "X" should be exchanged for the
tacho adaptor (option).
When operating with a Unimog equipped
with the on-board-computer "UNICOM I"
thesensor"X"shouldbeexchangedforan
adaptorcable(option).Herewith"UNICOM
I" and "AMADOS" are directly linked with
one another.

2.0 Important Informations
2.1 Attention Symbol
This symbol will always be found in such
places of this instruction book which
shouldespeciallybeadheredtoinorderto
comply with rules, adivce, hints and the
correct procedure of the operations as
wellastopreventdamagetotheimplement.
2.2 Hint-Symbol
This symbol marks machine's specific
pointswhichshouldbeobservedtoensure
the correct operation.
2.3 Declined use of the machine
"AMADOS" has exclusively been designed for the
usualoperationasadisplay-,monitoring-andcontrolling
device for agricultural machinery.
Any use beyond the one stipulated above is no longer
considered as designed use. The manufacturer does
not accept any responsibility for damage resulting from
this; therefore the operator himself carries the full risk.
Under "declined use" also the adhering to the
manufacturer's prescribed operation-, maintenance-
and repair conditions as well the exclusive use of
original AMAZONE spare parts is to be understood.
"AMADOS" may only be operated, maintained and
repaired by such persons who have been made
qcquaintedwithitandwhohavebeenadvisedaboutthe
dangers.
Allapplicable accidentpreventiveadviceaswell asany
further generally accepted safety-, working-, medical-
and road-traffic rules should be adhered ty.
Any damages resulting from arbitrary changes on
the "AMADOS" rule out the responsibility of the
manufacturer.
Before every operation and also during the operation
check your device for proper function and for sufficient
application accuracy of the machine.
Claims regarding damage not having occured on the
"AMADOS" itself will be rejedcted. This also applies to
damages due to application errors.

in [ha].
• monitores the speed of a drive shaft equipped with
arev.speedsensor.Ifthe ratedvalueisundercutby
more than 10 % an audible alarm sounds off and
simultaneously the display changes alternatively
from "operation display" to "fault display" (please
see para. 3.1.4.3).

AMADOS DB 521.1 06.97
6. Calibration of application rate
The broadcaster can only then be set to
spread accurately when the fertiliser
properties, especially the flowing
behaviour, are exactly known.
Thisflowingbehaviourmayalreadychange
after brief storing of the fertiliser.
For this reason, conduct a fertiliser
calibration test with the fertiliser to be
spread before every operation.
In the event of a drastic change of
application rate by more than 50 % it is
advisable to carry out a fresh calibration.
Preconditions for an accurate calibration are:
•Beforestartingthephysicalcalibrationprocess,the
requiredapplicationrateandworkingwidthmust
be entered into the computer.
• An adequate quantity of fertiliser in the hopper.
When calibrating the spread rate entered
into the AMADOS may not exceed the
value shown in column "max. spread rate
to be entered for calibrating" in table 3.1
for the entered working widths.

"AMADOS" now calculates a calibration factor
characteristic for the fertiliser and working width
used which can be called up on the display by
pressing the key .
- After completing the calibration test reinstall the
spreading disc.
How to conduct the calibration test when the
entered spread rate exceeds the maximum
spread rates mentioned in table 3.1:
Example:
Working width: 24 m
Wanted spread rate: 1300 kg/ha
Thusthemaximumallowablespreadrateforconducting
thecalibrationtest for24mworking widthof1010kg/ha
will be exceeded.
- Prior to the calibration test change the figure for the
entered spread rate of1300 kg/ha to the maximum
spread rate mentioned in the table of 1010 kg/ha.
- Continue with the calibration test as stated under
"procedure for the fertiliser calibration test".
- After having conducted the calibration test, enter
again the figure for the wanted spread rate, here
1300kg/ha.

For starting the operation simultaneously press the
Start
keys.
The section memory for the part area [ha] returns
automatically to "0" .
When one of the shutters is opened the computer
displays
• the momentary forward speed [k.p.h.].
• the current spread rate [kg/ha].

3.1.3 Spreading extremely small spread
rated, e. g. green manure seed and
slug pellets
Spread rates below 50 kg/ha (smallest
spread rates) will have an unfavourable
flowing effect of the material due to the
small diameter of the outlet opening and
therefore may lead to deviations of the
spread rate.
