The diagnostic alarms can be allocated to an output relay; for this purpose the Self-test relay pa-
rameter can be set (K1...K6) inside the Set \ Self-test Relay submenu.
Pilot wire diagnostic
Detailed diagnostic information about the pilot wire are available.
(Read \ Pilot wire diagnostic).

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.
