CALIBRATE
In general
Why and when must calibration happen:
Calibration with the initial operation of the tractor/wagon
combination (tractor + silage wagon) is essential for the
function of the weighing equipment!
Here, the conversion factors dependent upon the tractor/
wagon combination are determined and are used for
every weighing.
If there are differences between the determined weights
displayed and the actual loaded weights, a new calibration
is recommended.
It is recommended that a calibration be carried out before
every season.
What happens when calibrating:
The weighing equipment calculates the loaded weight
from pressure in the hydraulic system. In order to correctly
process the pressure value in the hydraulic system,
it is compared with the actual loaded weight using a
calibration .
The compared values are saved and used for every
weighing.
What prerequisites are necessary for
calibration:
- Scales on which the tractor/wagon combination can
be weighed for the reference weighing.
- Load (silage, green forage, etc.) in order to produce
the silage wagon’s max. transport weight.
Note:
A reference weighing with an approximate
max. transport weight increases weighing
equipment accuracy .
- The silage wagon must stand on level, firm ground for
calibration.
- The tractor/wagon combination must be just in
tension.
- The tractor and silage wagon must not be under brakes.
The tractor must be in neutral.
Note:
In order to avoid integrating any possible
distortion between tractor and silage
wagon drawbar in the calibration, it
is recommended the tractor/wagon
combination be allowed to ease off in the
direction of the calibrating site!
- Pick-up must be raised
- For the lift axle variation, move the servo to the swim
position.
Note:
When all these prerequisites have been met
then an exact calibration can be carried out
and, in the future, exact weighings!
How is calibration carried out:
1) If all conditions have been met, then a drawbar
calibration is started while empty. Drawbar calibration
takes place via the ISO-Bus Control.
2) When empty, the hydraulic pressure of the axles is
calibrated. Weight calibration takes place via the ISO-
Bus Control
3) In order to determine the reference weight, the tractor
and wagon are weighed separately on scales and the
values are entered into the ISO-Bus Control.
4) When full, the hydraulic pressure of the axles is
calibrated. Weight calibration takes place via the ISO-
Bus Control.
5) In order to determine the reference weight, the tractor
and wagon are weighed again separately on scales
and values are entered into the ISO-Bus Control.
6) The values determined are processed and calibration
is finished.
Important:
When weighing
the tractor empty
or full, take note
whether both
weighings are
“with driver” or
“without driver”!
Otherwise the
calibration is
incorrect.
