➨ Ten programs with up to ten program steps with preset values for vacuum and time can be set
and stored.
The screen-shot shows the factory-set values.
When ”Graphic” is selected the display shows a pressure vs. time curve (right screen-shot).
The number of the program with program step, the set vacuum, the actual vacuum and the runtime are
displayed.
The timeline in the diagram adapts automatically to the process time.

☞ Edit:
Preset values for the process run can be edited:
Time: Process runtime for each program step to reach a preset vacuum level or if setting ”Step”
runtime after having achieved the vacuum level. The summed up total process runtime is shown in
thebaseline.Attention:Apresetruntimeof99:59:59hoursinthenalprogramstepwillcausethe

Vacuum: Vacuum level to be attained.
Venting valve: Operating a venting valve to reach a preset vacuum level.
”Step”: ”Step” causes pump down as fast as possible to the preset vacuum level. As soon as the
vacuum level is reached the time meter starts running.
”Auto”: Auto = : automatic determination of a boiling point and adaptation to changes of the boil-
ing point within the preselected time interval. Auto = : only automatic adaptation to changes of
theboilingpoint.Theprogramstepisnishedwhentheselectedtimeorpressurevaluehasbeen

Selecting ”Auto” in combination with ”Step” in one program step is not possible.
☞ Open: Open programs (Program 0 - 9).
☞ Store: This command stores an edited program or the program of the last process to one of the stor-
age spaces 0 - 9.
☞ Delay: ”Delay”speciesthetimethecoolantvalvecontinuestorunafterprocessstop.
The ”Delay” is adjustable in a range of 1-300 minutes or can be set to ”Off”.
