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 upper limit temperature
inside the enclosure. Monitoring is performed in three steps. To
activate monitoring, set the parameter to 'On'. Sub-parameters are
displayed. Appropriately set the sub-parameters.
The value is displayed in Diagnostic value '31.TMIN - Minimum
temperature' / '32.TMAX - Maximum temperature' (Page 268). The
positioner triggers a message if the current value exceeds one of
the three thresholds.
Factory setting: OFF
J1.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
J2.LEVL1 - threshold 1
Adjustment range: -40.0C ... 90.0C
-40.0F ... 194.0F
Purpose: Use this sub-parameter to set the temperature for threshold 1.
The positioner triggers a threshold 1 message if the current tem‐
perature inside the enclosure exceeds threshold 1. This message is
only output if threshold 2 or 3 is not exceeded at the same time. The
process to activate and display this message is described in the
'XDIAG' parameter.
Factory setting: 75.0C
J3.LEVL2 - threshold 2
Adjustment range: -40.0C ... 90.0C
-40.0F ... 194.0F
Purpose: Use this sub-parameter to set the temperature for threshold 2.
The positioner triggers a threshold 2 message if the current tem‐
perature inside the enclosure exceeds threshold 2. This message is
only output if threshold 3 is not exceeded at the same time. The
process to activate and display this message is described in the
'XDIAG' parameter.
Factory setting: 80.0C
