The main unit/display, part no. MLMAINDISP2 is the central control unit of the
MultiLevel system.
It receives data from/sends data to the interface modules via the internal CAN
bus connection. For example, to the integrated display interface, wet leg sensor
interface (NM2WET-E) and the level sensor interface (MLIF).
The main unit stores and evaluates the data.
A "life test" is performed continuously between the main unit and all connected
interface modules. This ensures that all interface modules function properly.
Apart from the internal CAN bus connection there is also an external CAN bus
connection. This connects the MultiLevel system to the NoMix 2000 system
protection).
Since the MultiLevel in connection with the NoMix 2000 does not have its own
I/O interface, it sends telegrams to the NoMix 2000 via the external CAN bus,
for example in order to open/close foot valves and line valves.
