• The configuration will not be completely stored in the device if the supply voltage fails
• The transmitter detects a defective device configuration and signals this by the red

A diagnostic interrupt is not triggered unless the measured value is higher or lower than the
limit value by 3 °C (5.40°F).
A diagnostic warning is triggered immediately when the measured value exceeds the limit
value. The diagnostic interrupt is triggered in any case if the limit value is exceeded by more
than 2%.
during a write operation to the device. In this case, a new configuration must be written to
the device. The device will then revert to working in accordance with the specifications.

error" diagnostic bit.
CAUTION
has been exposed to temperatures beyond its ambient temperature limits (-40 °C to
+85 °C). In this case, the transmitter outputs the fault current set in its parameters as the
output signal. The "Ambient temperature error/electronics temperature error" flag
remains set in the device even after the power supply has been switched off and on
again.

– SIPROM T menu item for SITRANS TR200:
Device ➜ Device status ➜ Device reset after ambient temperature error
– SIMATIC PDM menu item for SITRANS TR300:
View ➜ Device status ➜ Device reset after ambient temperature error
The rest can only be performed if it has been ensured by sensor trim and D/A trim
that the transmitter is operating within the user's accuracy tolerances.
