G3.LEVL3 - threshold 3
Adjustment range: 0.1 ... 10.0
Purpose: Use this sub-parameter to set threshold 3 for the upper endstop in
percent. Set the threshold in a range from '0.1' to '10.0'.
The positioner triggers a threshold 3 message if the difference be‐
tween the upper endstop and the initialization value exceeds thresh‐
old 3. The process to activate and display this message is described
in the 'XDIAG' parameter.
Factory setting: 4.0
8.4.3.8 Monitoring the lower limit temperature 'H.\\TMIN'
H. TMIN - Monitoring the lower limit temperature
Requirement: The '52.XDIAG' Activating for extended diagnostics (Page 162) pa‐
rameter is set to 'On1', 'On2' or 'On3'.
Possible settings: ● OFF
● On
Purpose: 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 lower limit temperature in‐
side the enclosure. Monitoring is performed in three steps. To acti‐
vate 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
temperature' / '32.TMAX - Maximum temperature' (Page 224). The
positioner triggers a message if the current value undershoots one
of the three thresholds.
Factory setting: OFF
H1.TUNIT - temperature unit
Possible settings: °C
°F
Purpose: 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.
Factory setting: °C
