maximum speed and does not foresee the tolerance check.
-
The display, during the unload activity, shows the “
UNLOAD ALL
” message.
-
As soon as the weight reaches the TOTAL UNLOADING END a wait time starts equal to the WAIT FOR
DISCHARGE END (
).
-
Once the wait time is finished the activity ends, with subsequent disabling of the fast dosage and
product outputs.
-
The data of the executed dosage is automatically stored and transmitted through the serial line for
the printing or the storage on PC/PLC.
-
A wait time starts equal to the DATA READING TIME
(
) in order to allow the reading of the
activity data; the instrument waits for this time before passing to the following phase.

Split total unloading
a) Description
-
This activity has the purpose of completely unloading the scale after one or more loading dosages,
SPLITTING the dosage in various partial unloads which have a fixed partial target, programmable in
the formula (example: unload 2000kg in 20 dosages of 100kg):
-
In order to obtain a split total unloading activity, one should enter an unloading activity in the
activity database; then, in the formula, one should enter the unloading activity after one or more
loading activities, with a target equal to the partial TARGET, for example 100kg. By entering an
unloading activity as first activity of the formula, one obtains a partial unloading (see following
unloading method).
-
Each single unloading is managed as a partial unloading activity (see following unloading method for
details).
-
It is possible to program in the activity how the first unloading should start, once the previous
