8.17 Diagnostics functions
The diagnostic concept of the SITRANS TR200 and the SITRANS TR300 envisages that a
diagnostic warning can be set in the parameters for diagnostic functions that are used for
monitoring limit values. A diagnostic interrupt can be set in the parameters for diagnostic
functions that are used for monitoring error conditions.
Diagnostic interrupts are output via:
●
Analog output
● Operating indicator (LED)
● Only for SITRANS TR300: HART communication
Diagnostic warnings are output via:
●
Only for SITRANS TR300: HART communication
Diagnostic interrupt:The device goes into the alarm current state. In addition, the diagnostic
event is made available via the operating software. The following table summarizes all the
diagnostic functions that can be set in the parameters. If multiple errors occur
simultaneously, the priority settings apply. Priority 1 is the highest priority.
Diagnostic warning: The device transmits the diagnostic event that has occurred via the
operating software. The analog output value is unchanged.
