The digital fault recorder menu provides access to records stored within the D90
including sequence of events, fault report, transient records, and disturbance records. The
summary page displays the status of each function, as follows:
A green indicator indicates that the function is enabled and more than 20% of the
memory is available
A yellow indicator indicates that the available memory is between zero and 20%
A red indicator indicates that the memory is full
If the function is configured for protected mode, then the enabled indicator also switches
to red indicating that new records can be captured. If the function is configured for
automatic overwrite, then the element overwrites old records and the enabled LED
remains green.
For details on the indicators for the fault report, transient recorder, and disturbance
recorder, see
