4.2.3 Switching functions
The buttons in group D (see Figure 4.8.) are similar to main switches.
A number of functions such as adding gas to a package or automatic filling can be turned on
and off centrally here. Some functions can only be switched on if the packaging program
chosen permits this, so that a function cannot be switched on unintentionally. The functions of
the buttons are shown in table 3:
