12.5.1 Operating conditions for displaying the following diagnostics
information
Operating conditions for displaying the following diagnostics information:
• Diagnostic message 871 Near steam saturation limit: The process temperature is
less than 2K from the saturated steam line.
• Diagnostics information 872: The measured steam quality has dropped below the
configured limit value for the steam quality (limit value: Expert → System
→ Diagnostic handling → Diagnostic limits → Steam quality limit).
• Diagnostics information 873: The process temperature is ≤ 0 °C.
• Diagnostics information 972: The degree of superheat has exceeded the configured
limit value (limit value: Expert → System → Diagnostic handling → Diagnostic limits
→ Degrees of superheat limit).
12.5.2 Emergency mode in the event of pressure compensation
‣
Disable the pressure measuring cell: in the Disable pressure cell parameter (7747)
select the Yes option.
 The measuring device uses the fixed process pressure to calculate.
12.5.3 Emergency mode in event of temperature compensation
‣
Change temperature measurement: PT1+PT2 to the PT1 option, PT2 option or the Off
option.
 If the Off option is selected, the measuring device calculates by using the fixed
process pressure.
12.6 Pending diagnostic events
The Diagnostics menu allows the user to view the current diagnostic event and the
previous diagnostic event separately.
To call up the measures to rectify a diagnostic event:
• Via local display →  150
• Via "FieldCare" operating tool →  152
• Via "DeviceCare" operating tool →  152
Other pending diagnostic events can be displayed in the Diagnostic list submenu
