activity has ended: automatically or manually (by pressing the external INPUT 1 or the START
button). Each following unloading will be manually enabled by pressing the external INPUT 1 or the
START button: in this way the operator, for example, can change the container with each partial
unloading.
-
At the end of each single unloading the instrument checks if the weight is sufficient to execute a
further unloading: if the weight is lower than the TOTAL UNLOADING END + ACTIVITY TARGET
threshold the split unloading activity ends and the instrument automatically passes to the following
activity.
-
Therefore, in order to obtain a total unloading, one should enter a split unloading in the formula
(entering an unloading activity having a target different than 0), followed by a total unloading
activity (see previous unloading method for details).
-
If the WAIT FOR DISCHARGE END ( ) is set, only the total unloading will end and the relative
outputs be disabled, as soon as the weight reaches the TARGET and this time has passed: each single
unloading end is managed as in the partial unloading activity (see following unloading method for
details).
-
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.
