Program function

➨ Permits ten programs to be defined and stored, each with up to
ten program steps with preset values for vacuum and time.
+ Edit:
Use to define the preset values for the process run:
Time: Defines either the process runtime for each program step to
reach a preset vacuum level or, if programming a "Step", the runtime
after having achieved the vacuum level. The total process runtime is
shown in the base line. Attention: A preset runtime of 99:59:59 hours
in the final program step will cause the process to run endlessly. Ter-
minate the process by pressing the "STOP" key .
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 =
point automatically, and will automatically adapt to changes in the boil-
ing point until a preselected time interval expires.
Auto =
: indicates that the system will automatically adapt to chang-
es in the boiling point. The program step is finished when the selected
time or pressure value has been reached.
Selecting "Auto" in combination with "Step" in one program step is not
possible.
+ Open: Choose program (Programs 0 - 9).
+ Store: This command stores an edited program or the program of the
last process to one of the storage spaces 0 - 9.
+ Delay: "Delay" specifies the time the coolant valve remains open after
process stop.
The "Delay" is adjustable in a range of 1-300 minutes or can be set to
"Off" ("Off" means that the coolant valve closes immediately when the
process stops.).
