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.

Following information are stored in every record:
• Fault counter

• Date and time
• Fault cause (element trip)
• Phase currents

Note 1 Fault 0 is the newest fault, while the Fault 19 is the oldest fault
Note 2 Data are stored in non volatile memory; they are held in spite of power down
Note 3 Counter is updated at any new record; it may be cleared by means ThyVisor
