The manual mode is activated by calling up the main window "Manual".
Delta 1-24 LSC& Delta 2-24 LSC& 6 Operation 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.
Delta 1-24 LSC& Delta 2-24 LSC& 6 Operation condensate water or another medium, the opening time of the drain valve can be pre-selected in this dialog box. • Leakage test (4) This function is optional (see chapter 6.6 - "Optional extensions"). This button displays the parameters that are used for the leakage test. In addition, the test time and the chamber volume must be stated (depending on the accessories that are used).
Delta 1-24 LSC& Delta 2-24 LSC& 6 Operation Fig. 56: Representation of a freeze-drying process Program sections When the programmer module executes a freeze-drying process, it executes the various sections that were created one after the other until the last section is completed. Within the various sections, the system calculates linear ramps for the temperature and vacuum. These ramps start with the set value of the previous section and end with the set value of the current section.
Delta 1-24 LSC& Delta 2-24 LSC& 6 Operation Conditions for switching to the next section For all of the program sections to be executed automatically, certain switching conditions must be fulfilled at the end of each section. If these conditions are not fulfilled, e.g. due to incorrect set values, a corresponding process message will be displayed. Ice condenser temperature: This value is checked only when the system switches from freezing (loading) to drying. The ice condenser temperature must be -40°C.
Delta 1-24 LSC& Delta 2-24 LSC& 6 Operation Vacuum pump warm-up Apart from the execution of the various sections, the PGMplus programmer module also controls other tasks that need to be performed during the process run, e.g. the automatic activation of the vacuum pump. If the pressure control valve is closed, the PGMplus programmer module shifts the warm-up phase of the vacuum pump to the freezing phase so that it is directly before the first drying section.
Delta 1-24 LSC& Delta 2-24 LSC& 6 Operation Creating a blank program (1) This button is used to call up a blank program template. Only section 1 is pre-defined as the loading section. In this phase, the start conditions of the programs are defined. The room temperature (20°C) is the standard default. If the product is frozen outside the freeze-dryer (double-chamber method), the shelf temperature must be adapted accordingly in section 1.
Delta 1-24 LSC& Delta 2-24 LSC& 6 Operation • Pressing the button “Diagram” (3) displays the program in the form of a diagram. • Pressing the button “Program name” (2) calls up an input field in which the name of the program can be changed. • The button “Save” (7) can be used in between or at the end of the program creation in order to save the program. • The button “Program” (1) calls up the main window. The system will ask the user whether the program shall be saved if this has not been done yet.
Delta 1-24 LSC& Delta 2-24 LSC& 6 Operation In contrast to the pressure increase test in the manual mode, repeated pressing of the button in the program mode enables the selection of different variants. • Periodic pressure increase test: The test will be performed periodically during the entire main or final drying phase. The parameters "Duration test" and "Time between tests" apply. The maximum pressure increase is limited to 100%, referring to the actual value at the beginning of the measurement.
Delta 1-24 LSC& Delta 2-24 LSC& 6 Operation Fig. 62: Dialog box "Pressure increase test" in the program mode Option: Comparative pressure measurement (see chapter 6.6 - "Optional extensions") The indication of the measurement value "dp Comp" can be configured in chapter 6.5.1.1 - "Main window "Manual"" under "Actual values of the current process" in the dialog box "Select actual value". NOTE The comparative pressure measurement can be activated or deactivated by pressing the button in the dialog box.
Delta 1-24 LSC& Delta 2-24 LSC& 6 Operation Fig. 63: Dialog box "Comparative pressure measurement" Program templates (2) The PGMplus programmer module offers 14 different program templates that include recipes for all kinds of freeze-drying applications. They are suggestions for orientation purposes and must be adapted to the specific area of application of the freeze-dryer. Following the selection of a program template, a window containing information concerning the drying process will be displayed.

Delta 1-24 LSC& Delta 2-24 LSC& 12 Glossary 12 Glossary Comparative pressure measurement During the sublimation, i.e. when the concentration of water vapour molecules is rather high in the atmosphere, the value that is provided by the gas-type dependent vacuum sensor of the "Pirani" type (e.g. Thyracont VSP 62/63) deviates from the value that is provided by a capacitive vacuum sensor (e.g. MKS 722B).
Delta 1-24 LSC& Delta 2-24 LSC& 12 Glossary Double-chamber method Drying on shelves outside the ice condenser chamber is referred to as a double-chamber system. The advantage compared to the singlechamber method is the considerably higher product capacity. In addition, the product chamber can be isolated from the ice condenser chamber by an intermediate valve in order to perform a so-called pressure increase test for determining the end of the drying process.
