37 yes Maintenance required The device detects problem(s), which are less severe compared to
the diagnosis "Measurement failure". But still the measurement
values are accurate. The output values are still valid, but this may
change in the near future. Check detailed diagnosis to solve the
problem.
39 yes Ident_Number violation Ident. Number Selector was modified while cyclic data transfer
was active. To clear this message perform one of the following
actions:
• Reset Ident. Number Selector to its former setting
• Stop cyclic data transfer
• Restart the device
40 2 Maintenance alarm The device or measurement is defective and cannot measure.
Related output values are invalid. Typically a repair or
replacement of the device is required.
Check detailed diagnosis. Restart the device. If the error occurs
again: send the device back to the manufacturer with an
indication of the error.
41 2 Maintenance demanded The device or application condition is in a way that the
measurement accuracy may be reduced. But still the
measurement value follows the source. E.g. the device may be
operated outside its specified operating range.
Check detailed diagnosis. Restart the device. If the error occurs
again: send the device back to the manufacturer with an
indication of the error.
42 2 Function check Simulation is active. Disable simulation to clear this message.
55 yes Extension available Refer to detailed diagnosis in bits 56 to 103.
56 3 C – Process
(classification fixed - not changeable)
Process related "Function check" running. E.g. the measurement
values may be simulated values for a currently performed check.
The related output values are temporarily invalid. Turn off
"Function check" to change back into measurement mode / 6.
57 3 C – Configuration
(classification fixed - not changeable)
Configuration related "Function check" running. E.g. the
measurement values may be simulated values for a currently
performed check. The related output values are temporarily
invalid. Turn off "Function check" to change back into
measurement mode / 6.
58 3 C – Electronics
(classification fixed - not changeable)
Converter Electronics related "Function check" running. E.g. the
measurement values may be simulated values for a currently
performed check. The related output values are temporarily
invalid. Turn off "Function check" to change back into
measurement mode / 6.
59 3 C – Sensor
(classification fixed - not changeable)
Sensor related "Function check" running. E.g. the measurement
values may be simulated values for a currently performed check.
The related output values are temporarily invalid. Turn off
"Function check" to change back into measurement mode / 6.
60 3 F – Process
(classification fixed - not changeable)
Process related settings are defective. Related output values are
invalid. A repair or replacement of the device can be necessary.
Check process parameters / 4 - restart the device – if the error
still occur contact the service department of the manufacturer.
61 3 F – Configuration
(classification fixed - not changeable)
Configuration is defective. Related output values are invalid. A
repair or replacement of the device can be necessary. Check
configuration / 4 - restart the device – if the error still occur
contact the service department of the manufacturer.
62 3 F – Electronics
(classification fixed - not changeable)
Converter Electronic is defective and not able to measure.
Related output values are invalid. Typically a repair or
replacement of the device is required. Check converter / 4 -
restart the device – if the error still occur send back the device to
the manufacturer with an indication of the error.
