The three mode screens—the Automatic Mode screen, the Manual Mode screen, and

P.4 Automatic Mode
Automatic mode is used to run mixing according to recipes; lists of instructions
composed by the user to run the mixing process at different speed settings and/or at
certain time schedules. The Levmixer software includes a library of 10 recipes. Each
recipe contains up to 10 instructions executed consecutively during a run. Each
instruction consists of 3 user defined parameters: duration of mixing phase, duration of
pause phase and speed of rotation. All the recipes have duration of mixing and pause
factory pre-installed to values of zero, and speed of rotation set to 20 RPM. Any recipe
with all mixing phase durations set to zero considered an “empty” recipe. If the
operator tries to run such a recipe a notification is displayed on screen.
