3.5 Counter reading check (Countbox, Sortbox)
Good parts counting with preselected number of items
When the last good part of a counting process reaches the
reject position for bad or foreign parts, output O/13 will be
switched from LOW>HIGH (nominal number reached) via the
connection “Controller”.
In order to start the counting cycle again, you must switch
output I/32 from LOW>HIGH. The Checkbox then resets out-
put O/13 from HIGH>LOW and begins the new counting cycle.
Pin Signal level Meaning
I/32 HIGH Starts the new counting cycle
O/13 HIGH Preselected counter reading
(of all parts types) reached
O/13 LOW Preselected counter status not
yet reached.
