The '50.XDIAG' Activation of extended diagnostics (Page 170) pa‐
rameter is set to 'On1', 'On2' or 'On3'.
● OFF
● On
The current temperature inside the enclosure of the field device is
recorded by a sensor on the basic electronics. Use this parameter
to activate continuous monitoring of the low limit temperature inside
the enclosure. Monitoring is performed in three steps. To activate
monitoring, set the parameter to 'On'. Sub-parameters are dis‐
played. Appropriately set the sub-parameters.
The value is displayed in Diagnostic value '31.TMIN - Minimum tem‐
perature' / '32.TMAX - Maximum temperature' (Page 264). The po‐
sitioner triggers a message if the current value undershoots one of
the three thresholds.
OFF
°C
°F
Use this sub-parameter to set the temperature unit '°C' or '°F'. The
selected temperature unit is then also applicable for all other tem‐
perature-based parameters.
°C
-40.0C ... 90.0C
-40.0F ... 194.0F
Use this sub-parameter to set the temperature for threshold 1.
The positioner triggers a message if the current temperature inside
the enclosure undershoots threshold 1. The process to activate and
display this message is described in the 'XDIAG' parameter.
