Endress+Hauser Proline Prosonic Flow P 500 Functional Safety Manual page 31

Proline Prosonic Flow P 500 HART
3. Document results of proof test in accordance with the safety management guidelines
applicable to the system.
NOTICE
With the test sequences described, at least 48 % of the undetected dangerous failures
can be detected. The influence of systematic errors on the safety function is not fully
covered by the test. Systematic errors can be caused, for example, by medium properties,
operating conditions, build-up or corrosion.
‣
If one of the test criteria from the test sequences described above is not fulfilled, the device
may no longer be used as part of a protective system.
‣
Take measures to reduce systematic errors.

(0354–1 to n)
Use this function to switch simulation of the current output on and
off. The display alternates between the measured value and a
diagnostic message of the "Function check" category (C) while
simulation is in progress.
On
Description
The desired simulation value is defined in the Value current
output 1 to n parameter.
Selection
• Off
Current simulation is switched off. The device is in normal
measuring mode or another process variable is being simulated.
• On
Current simulation is active.
