Operator Panel OP3
Edition 11/99
The OP3 is used to operate and monitor a system for producing and bottling
different fruit juices. The system consists basically of a mixing unit and a
bottling machine.
Mixing unit
The ingredients for the fruit juices are contained in three tanks.
Depending on the juice that you wish to manufacture, ingredients are mixed
in certain ratios.
Bottling machine
After it has been mixed, the fruit juice flows into the bottling tank after a
valve has been opened and is then bottled in the correct quantities. The
bottles are conveyed on a belt. Before being filled, they are checked for
breakages. After they have been filled, the bottles are capped, labeled and
transferred to pallets.
The configured basic screen might be as shown in figure 11-2. It consists of
static text only.
