weight range they belong. This would clash with the purpose for which
the weight ranges are used, i.e. to prevent pieces from being rejected in
any case.
6.4.7 W.B. - Crate weigher
On access to the process, the initial PLU is loaded but Weight Bounding
is not loaded until the arrival of the piece, which will then be associated
to a PLU. This is when the associated Weight Bounding archive will be
checked and loaded. When the piece arrives, the terminal first checks to
make sure that the weight is within the range set in the PLU associated
with the piece on the scale. If the piece is valid, it will be counted in this
PLU. If the piece is rejected, Weight Bounding will be activated so as to
check that the piece is within one of the 9 in the EIGHT BOUNDING
function. If it is, the relative PLU will be loaded so that it can be
procssed. However, in this case, the weight range of the destination PLU
is also considered valid but any WEIGHT BOUNDING that may have
been set in this PLU will not be evaluated. This means that the piece
may be definitively rejected because it is not within the range (within or
outside the programmed values) of the PLU selected last.
An explanatory example of the combined crate weigher-WB operating
mode occurs in the poultry sector, where the weight of crates of the
same PLU but with different weights (1 kg, 1.1 kg, 1.2 kg) must be
discriminated.
In all cases, the piece will be rejected if a PLU that does not exist in
the archive is loaded in a WEIGHT BOUNDING range. The same
thing happens if the Weight Bounding code loaded in the PLU does
not physically exist in the archive.
