Siemens 7SJ82 - Defect Severity 2; Defect Severity 3

Indication Type Group
Warning
Explanation
VI-3ph: Mess.Volt.Fail detected:
(_:300) Failure
SPS CFC
Measuring-voltage failure detected:
Check the exterior wiring.
Blocking: Appropriate functions are
either blocked definitely or the blocking
can be set individually.
Defect Severity 2
Faults of defect severity 2 are fatal device faults that lead to an immediate restart of the device (reset).
This occurs when the device data is corrupted (for example, RAM memory), if a restart prevents restoration of
data consistency. The device goes briefly out of operation, a failure is avoided.
Life contact Is terminated during the restart
Red error LED Is activated during the restart

NOTE
If the fault of defect severity 2 has not be been removed after 3 unsuccessful restarts (reset), the fault is
automatically assigned to defect severity 3. The device will automatically turn to the fallback mode.
Log
For every device error with a subsequent restart (reset), only the restart can be detected in the operational log.
The actual supervision indication is entered in the device-diagnosis log at the point in time of the fault detec-
tion and before the restart. These indications are recorded with a real-time stamp and are thus available for
later analyses. The device-diagnosis log contains expanded fault descriptions. There you also receive recom-
mendations of corresponding corrective measures for each detected device error.
You can find further information on handling the logs in chapter 3.

Defect Severity 3
Faults of defect severity 3 are fatal device faults that lead to device immediately going into the fallback mode.
The signal (_:301) Device status goes to the Alarm state. The Warning state is not supported for this
signal.
