6.15.2 Operation of scales
The following items are vitally important to ensure an optimal weighing result:
– The belt tension should be as low as possible.
– The rollers at the weighing cells (1) and the preceding (2) and following (3) rollers
must be regularly cleaned. It may be necessary to clean them several times a day
depending on the soil characteristics.

– During weighing move the truck conveyor slowly and as smoothly as possible.
– Keep the inclination angle of the truck conveyor as constant as possible during
weighing.
– Do not lift the truck conveyor at too much of an angle if at all possible. The display
of the inclination angle on the terminal should green if at all possible. If the colour
changes to orange, weighing results may be incorrect.
– Soil on the conveyor will seriously affect the weighing result. For this reason run a
zeroing (see page 261) at regular intervals. If the beets are very dirty or the soil
is very sticky we recommend zeroing at every 3rd to 5th truck. Zeroing is required
because otherwise the dirt particles adhering to the conveyor will be regularly
weighed with the load.
A new zeroing is required whenever the proportion of soil on the conveyor
changes. The same applies EVERY time the machine is moved. In our experience
the major cause of incorrect weighing results is because zeroing is not carried out
frequently enough.
– If weighing results are incorrect in spite of regular zeroing, the scales must be
recalibrated (see page 264).
