Translation of the original operating manual
NOTE
If in one section the value " " (infinite) is selected for a process phase, the
next phase must be started manually via the button "Operating mode:
select/start".
In the manual mode, the set values of the active phase can be changed
during the process run. In this case, the control system adapts the unit to
the new set values as quickly as possible.
After the completion of a phase, the system switches to the next phase
without switching the unit to standby. The transition from "freezing" to
"warm-up" takes place automatically. After the completion of the warm-up
phase, this dialog box will be displayed:
Fig. 54: Dialog box after the completion of the warm-up phase
The unit will remain in the warm-up phase until you confirm.
The transition from "main drying" to "final drying" again takes place
automatically. After the completion of the "final drying" phase, the system
displays another enquiry with which the freeze-drying process will be
terminated. The unit remains in the "run" mode until the enquiry is
confirmed.
The process can be stopped any time by pressing the "Stop" button. In this
case, the unit will be switched to standby.

6.5.2.1 Entering set values in the manual mode
The system has stored set values for every phase, and for every value
there are pre-defined value ranges that can be determined in the various
dialog boxes by pressing the buttons "min" and "max".
In order to protect the product, a safety pressure value can be entered in
every drying section.
