This machine had a multitude of problems before our retrofit. Since then, summer of 1999, there has been only one machine problem which turned out to be a defective pressure switch.

Here is the finished operator's interface. This is a touch screen which is backed up with an industrial keyboard mounted on a shelf below the screen.

Operators Interface
