The failure indication indicates a fault in
the analog-digital converter at the
power input.
•
Check the exterior wiring.
•
If the fault is not remedied, contact
the Customer Support Center.
Quality: The internally managed current
measured values are marked with the
invalid quality attribute.
Blocking: The protection functions
based on current measurement are
blocked.

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.
