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.

Fault recording - SFR
Recording
[1]
is triggered by:
Relay activation (OFF-ON)
External trigger (binary input) programmed as Fault trigger
Element pickup
Twenty events are recorded into a circular FIFO (First In, First Out) buffer.
[2]
Following information are stored in every record:
Fault counter
[3]
Date and time
Fault cause
Phase currents I
L1r

Inputs
Outputs
Fault cause info (faulted phase)
Event recording - SER
Recording is triggered by:
Relay switching (OFF-ON or ON-OFF).
External trigger (binary input).
Setting change.
Three hundred events are recorded into a circular FIFO (First In, First Out) buffer.
[4]
Following information are stored in every record:
Event counter
[5]
Date and time
Event cause (binary input/output relay/setting changes)
Oscillography - DFR
Upon programmable trigger, the fault records are recorded in COMTRADE format; the sampled mea-
sures (24 sample per cycle) are stored in a circular shift memory buffer.
The fault record are self-triggered; they are stored in sequential order up the allocated memory is
used up after which the oldest memory is overwritten.
An operating procedure example for the digital fault recording is illustrated inside the ThySetter
section.
Note 1 Data concerning the twenty events are stored into non volatile memory; they are held in spite of power down
Note 2 Fault 0 is the newest event, while the Fault 19 is the oldest event
Note 3 Counter is updated at any new record; it may be cleared by means ThySetter
Note 4 Event 0 is the newest event, while the Event 299 is the oldest event
Note 5 Counter is updated at any new record; it may be cleared by means ThySetter
