Translation of the original operating manual
Special equipment: Inertisation (5)
(see chapter 6.7 - "Optional extensions and special equipment")
If the "Inertisation" option is active and the freeze-dryer is in the "Standby",
"Manual - Freezing", "Program - Loading" or "Program - Freezing" mode,
the automatic inertisation of the drying chamber will be performed for the
preselected inertisation time after the loading door has been closed. The
operating mode then switches to "Run Inertisation".
Fig. 38: Dialog box "Inertisation"
A successful inertisation is a prerequisite for continuing the various
processes in the following operating modes:
• Manual
• Program
• Defrosting
• Media drain.
All other operating modes can be started without successfully completing
the inerting sequence.
The following parameters can be set:
• The inertisation time determines the effective inertisation duration with
open inlet and outlet valves and can be set in a range of 1...9999
seconds.
• The parameter "Delay on" determines the duration from the opening of
the inlet valves to the opening of the outlet valves. The setting range is
0...99 seconds.
• The parameter "Delay off" determines the duration from the closing of
the inlet valves to the closing of the outlet valves. The setting range is
0...99 seconds.
An inertisation process can be stopped any time by pressing the "Stop"
button.
NOTE
If the inertisation has been started in the "Manual - Freezing", "Program -
Loading" or "Program - Freezing" mode, the "Stop" button will also abort
the freeze-drying process!
