Translation of the original operating manual
Option: Lifting hoist

(see chapter 6.6 - "Optional extensions")
This function is described in the separate operating manual of the lifting
hoist.
Button "Set" (5)
This button is used to enter the set values for the individual phases of the
freeze-drying process prior to the start of the process. Value ranges have
been saved for the various phases. These value ranges can be displayed in
the input window with the aid of the buttons "min" or "max" (see chapter
6.5.2.1 - "Entering set values").
Dialogue box "Process and equipment messages" (6)
This dialogue box is used to view and save all of the error messages and
other messages. In the event of an error or message, the window “Process
and equipment messages” will open automatically. In addition, a sound
signal is emitted until the error is acknowledged.
There are three categories of faults:
• Red:
error messages
• Orange: process messages
• Yellow: general messages
The representation of the message provides information about its current
status. A double frame around a message means that the error has not
been eliminated yet. The colour of the button "quit" changes from blue to
grey once the message has been acknowledged.
Fig. 28: Representation of an error message
The advantage of this system is that faults that occurred during the night
can be discovered the next day even if the cause of the fault has already
been eliminated.
The dialogue box cannot be quit until all of the messages have been
acknowledged.
If a message has been acknowledged even though the fault has not been
eliminated, the button "Process and equipment messages" will be displayed
in the respective colour of the fault in the main window.
