10.1 Touch screen display
The touch screen display (Fig.22) is found on the front side of the machine and is connected to
the mainboard using a flat cable.
The machine will be operated using the touch screen display.

10.2 Mainboard
The mainboard is at the back of the machine and it is powered by an external (switched) power
supply. This board contains the machine's inputs and outputs.
Saved settings such as the recipe settings, counters, etc. are stored here.
When replacing this circuit board all customer-specific settings will be lost.
The mainboard also contains safety relays, which in case of an error interrupts the power supply
to the components.
