Fault recording - SFR
Recording is triggered by one or more causes (up to 8 simultaneous):
Activation (OFF-ON transition) of any relay programmed for trip of protection or control element
External trigger (binary input programmed as
Fault trigger
)
Twenty events are recorded into a circular FIFO (First In, First Out) buffer.
