4) This value takes into account all failure types of the electronic components as per Siemens SN29500
5) All diagnostic functions are executed at least once during this time. For operation in high demand mode
according to IEC 61508, the safe use of the devices is limited to a safety function demand rate of ≤ 1/50 h.
6) Maximum time between fault detection and fault response.
Note
The measuring device has been developed for use in "Low Demand" and "High Demand" mode.
Explanation
Our in-house quality management system saves information on safety-related systematic errors that will become
known in the future.

4.1 Definition of the safety function
The measuring device's permitted safety functions are:
Monitoring of a maximum or minimum volume flow or a volume flow range for liquid media
4.1.1 Safety-related output signal
The measuring device's safety-related signal is the 4–20 mA analog output signal (output;
input 1). All safety measures refer to this signal exclusively.
