When the desired temperature is achieved, the hold function will maintain that
temperature for the programmed length of time. The microprocessor control has a
built in memory of the last entered program to allow the identical protocol to be
repeated by simply pushing the RUN button. A typical 3 segment program is
shown in Figure 5.
Automatic Start-Up of Freeze Dryer
Vacuum
At the end of Segment 1 Hold, if the StopperingTray Dyer is connected to the
Freeze Dry System base unit, the vacuum provided by the Freeze Dryer will start
automatically. The base unit should have the refrigeration started in manual mode
to allow it to reach temperature while the Tray Dryer is processing Segment 1 of
the program. (Do not start the base unit’s refrigeration using automatic mode.
This will not allow the Tray Dryer to start the vacuum on the Freeze Dryer).
Connect the Tray Dryer to the Freeze Dryer with cable #7353403 (this cable is
shipped with the Tray Dryer). One end of the cable plugs into the 4-pin connector
(Output to Freeze Dryer) on the back of the Tray Dryer in the lower right hand
corner of the unit (when viewing the back of the unit), and the other end of the
cable plugs into the 4-pin connector (Stoppering Tray Dryer Input) on the back of
the Freeze Dryer in the upper right hand corner of the unit (when viewing the
back of the unit).
