3  FUNCTION SELECTION AND INPUTS 
3.1 Operating Terminal 
The DCU3 - system has an especially developed touch screen terminal for display of all process pa-
rameters and for operation of the entire unit. This „touch terminal“ has integrated „touch keys“ where 
the operator can select the menus and the related subfunctions, enter data and select and switch-over 
the modes for fermentor operation. In general the terminal is operated simply by pressing the screen 
at the position of the displayed keys.  
The touch terminal is adjustable to provide an optimum angle of vision:
