The controller can be adapted to the specific application by choosing another basic
setup than

”Vacuum control”

(factory-set), see section

”General view basic set-

ups”.

The status of the controller respectively of the connected accessories is displayed by
corresponding symbols on the LCD. After switching on the

version of the software

is

displayed. Then the basic setup is displayed as well as the symbols ”coolant valve”
and ”venting valve”, if the valves are preselected.
