Operating sequence fertiliser spreader ZA-M
AMATRON II-A DB 599 09.01
Fig. 17
F
AMATRON II-A automatically recog-
nises from which sensor (even in
case of several sensors) the signals
for determination of the impulse fig-
ure are received.
- Stop after 100 m. The display (Fig. 17/1) now
shows the determined impulse figure. By
pressing key
=
Eingabe
Input
the determined value is
stored.
• By pressing key
T2
(Calibrat.) a fresh cali-
bration procedure can be started.
• By pressing key
T4
(Next) the working width
can be entered in the next display (see para.
6.2.2).
Manual entering of the known value:
Stop the vehicle and by pressing key
=
Eingabe
Input
select
the range (implement, gearbox or radar) for which
the impulse figure is known.
Enter the known figure in the data block "machine"
"impulses/100 m" via the ten digit key board and
confirm by pressing key
=
Eingabe
Input
.
• By pressing key
T2
(Calibrat.) the impulse
figure can again be measured.
• Press key
T4
(Next) to enter the working
width in the next display (please refer to para.
6.2.2).
I
In case of deviations between
• the actual spread rate and the de-
sired spread rate
• the finished area determined and
displayed by AMATRON II-A and
the actually finished area
newly determine the calibration figure
by travelling along a calibration dis-
tance of 100 m (please refer to chap-
ter "impulse figure unknown").
6.2.2 Menu "working width"
Fig. 18
AMATRON II-A requires information about the
working width to control the shutter slide and to
determine the worked area. Enter the desired
working width in m (Fig. 18/1) via the ten digit key
board and confirm by pressing key
=
Eingabe
Input
.
• By pressing key
T4
(Next) the calibration
factor of the spread rate can then be deter-
mined (see para. 6.2.3/Fig. 19).
6.2.3 Determining the fertiliser calibra-
tion factor
The fertiliser calibration factor determines the con-
trolling behaviour of AMATRON II-A and depends
on
- the flowing behaviour of the fertiliser to be
spread,
- the entered spread rate and
- the entered working width.
The fertiliser flowing behaviour on the other hand
depends on
- the fertiliser storing and storing time,
- climatic conditions and
- working conditions.
I
The fertiliser flowing behaviour can
change even after a short storing
time.
Therefore newly determine the fertil-
iser calibration factor before any op-
eration.
