Parameter.
1 Time Constant The time constant smoothes the output signal. Statistical fluctua-
tions, as well as level fluctuations due to the process, e.g. by agita-
tors, are smoothed. A time constant of 20 s is usually reasonable.
2 Error Handling Displays the current state NORMAL, or SENSITIVE set under Set
Error Handling.
3 Set Error Handling Here you can set a different weighting of errors and error handling:
• SENSITIVE
All faults cause the current output to report a Fault current. To
also get warning messages, you must also evaluate the mes-
sages via the HART
®
signal or the digital output.
The setting SENSITIVE is automatically enabled when the
Safety Mode is selected.
• NORMAL
Only fatal errors are reported as a fault current. Thus, the mea-
sured value via the current signal will fail only if the measure-
ment can no longer be used.
To also get minor error and warning messages, you must also
evaluate the messages via the HART
®
signal or the digital out-
put.
IMPORTANT
You may select the NORMAL setting only if hazards to persons or
the environment or damage to property as a result of a faulty mea-
sured value can be ruled out.
To use the digital output for the above mentioned messages, you
need to use the setting WARNING + ERROR in the menu Digital
Out Function (Device Config Setup  I/O Setup  Digital
Output  Digital Out Function, page 3-357).
Tip
Error handling is described in detail in chapter 8 starting on page 3-
429.
