Setting suction wand assignment/blocking suction wands

Note
You can set the wand assignment and blocking times
for pellet supply only for pellet supply with a vacuum
system and when using an automatic changeover unit.
Blowing pellets into the pellet store results in an
uneven height of pellets stored inside the storage area.
In order to enable the pellet store to be emptied uni-
formly, the proportion of supply volume (assignment in
%) can be adjusted individually for each suction wand.
