5.5 Diagnostic information according to NAMUR NE 107
Diagnostic information about the connected sensor/sensors and the transmitter is available in
the configuration software ConSoft.
The HART diagnostic messages are generated in accordance with NAMUR NE107.
The following are examples of diagnostic information available both in ConSoft and as HART
messages:
• Sensor break (failure / sensor wire break on Ch1 or Ch2)
• Sensor short-circuit (failure / sensor wire short-circuit on Ch1 or Ch2)
• Sensor low isolation (failure / low internal isolation in sensor on Ch1 or Ch2)
• Sensor drift (failure / sensor drift between Ch1 and Ch2)
• Sensor backup, automatic switchover from defective sensor (maintenance required / change
the sensor on Ch1 or Ch2)
• Transmitter error (failure/transmitter error, non-correctable in the transmitter)
For complete information about all diagnostic information available from the 520 series
transmitters, refer to Table 5, 6, 7 and 8 below.

Error message Error correction
Transmitter C
Primary variable out
of limits
Check the limits for connected sensor. Replace
the sensor allocated to the primary variable.
Transmitter C
Non-primary variable
out of limits
Check the limits for connected sensor. Replace
the sensor allocated to the non-primary variable.
Transmitter C
Primary variable
analog output
saturated
Check the limits for connected sensor. Ambient
temperature is higher then stated limits for
sensor, which is allocated to the primary variable
analog output. Replace the sensor allocated to
the primary variable analog output.
Transmitter I
Primary variable
analog output fixed
Transmitter in multi-drop mode or loop test
Transmitter C More status variable Check device specific errors for more information
Transmitter I Cold start Transmitter is in cold start mode

Make a self test to find out more. Check even
device specific diagnostic. If the error remains
replace the device.

Transmitter M Maintenance required Check Device specific diagnostic for more
information about sensors and transmitter.
Transmitter M Device variable alert
Check Device specific diagnostic for more
information about sensors and transmitter.
