8 Error Handling
Errors are indicated by the digital output and/or via fault current.
Error messages are displayed on the HART
®
Communicator. All
error messages are stored in the error log together with date and
time. To view the error log, select Device Config Diagnostic
Log Error Log.
8.1 Error Handling Modes
The behavior in case of errors is dependent on the weighting set in
Error Handling (Device Config Setup Signal Condition
Signal Parameter, chapter 2.16, page 3-329): NORMAL or
SENSITIVE.
Both operation modes behave as follows:
• 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.
You may select the NORMAL setting only if hazards to persons or
damage to property a as a result of a faulty measured value can be
ruled out.
Select SENSITIVE if system safety is an important issue. Use
NORMAL if a failure of the measurement is non-critical for human
health and the environment and production safety is an important
issue.
To use the digital output for the above mentioned messages, you
need to use the setting WARNING + ERROR on the menu Digital
Out Function (Device Config Setup I/O Setup Digital
Output Digital Out Function, see chapter 2.30, page 3-357).
