Fault deletion counter

An individual deletion counter runs for every fault detected. It determines the storage duration of the related fault.

When a fault is first detected, the deletion counter is set to 80, for example (suspected fault).

If an unshedded fault is detected as having been remedied, the deletion counter is set to 10, for example (fault did not occur often enough to be confirmed).

Whenever a shedded fault is detected, the deletion counter is set to 40, for example. This value is retained until the fault is detected as having been remedied.

The deletion counter is decremented by 1 after every warm-up cycle if the fault in question is an unshedded fault or is detected as having been remedied (faults that are confirmed, but are not detected as having been remedied are not decremented in the deletion counter). If the deletion counter reaches the value 0, the fault is deleted from the memory.
