3.7.2 System check
An internal system check monitors the data transfer and sensor signals with
regard to plausibility. Errors are detected by continuous self-monitoring of
the system. Error messages are displayed in the process & equipment info
menu (see chapter 6.5.3.4 - "Process and equipment information" or
chapter 7.1.1 - "Error messages").

3.7.3 Power failure safety
The unit stores the current process parameters cyclically. In the event of a
power failure, the electromagnetic stop valve will close automatically, the
rotor chamber will be aerated by the aeration valve and the rotor
decelerates brakeless. After the restart of the power supply, the
evaporation process continues with the last stored parameters.
