The light sensor respectively light barrier 1 at the beginning of the storage queue
can be displaced in the direction in which the jars/glasses run. It should be adju-
sted in such a way that the necessary maximum number of jars or glasses per
row + 1 jar/glass can be counted and that no undefined switching condition can
occur, meaning that a sensor may not be able to rest exactly on the switching
point, based on the switching depth.
The light scanner respec. the light barrier 2 can be adjusted towards the direction
of the moving glasses, so that the row stopper can react according to the size
if the bottles in the appropriate moment.
By equal setting of the scanning deep for all channels a adjustment of the light
scanner respec. the light barrier is not necessary.
