Fault Storage Settings
Parameter: Fault Storage > Max Fault Rec Time
•
Default Setting: 2 s
Sets the time period from fault trigger during which the operation of any LEDs is recorded.
NOTE
To achieve accurate instrumentation values for the fault records when testing, ensure a drop off delay is
applied to the test set so that the injected quantities remain on for a short duration, typically 20 ms, after
the relay has issued the trip output. This extended period of injection simulates the behavior of the power
system where faulted conditions are present until CB operation.
Parameter: Fault Storage > Clear Faults
•
Default Setting:
This is used to delete all stored fault records.
The faults can also be deleted from a binary input or communication command.
Configuration > Data Storage > Fault Storage
