Measures
• RMS value of fundamental component for phase currents (I
L1
, I
L2
, I
L3
)
• RMS value of fundamental component for measured residual current (I
E
)
Circuit breaker
The CB and Trip Circuit Supervision states are provided
• Position Open - Closed - Unknown
• TCS On - O
and the binary inputs state:
• IN1-52b On/O
• IN2-52a On/O
• IN3-TCS On/O
Counters
For every protective element and control function several counters are available; the partial coun-
ters can be cleared by the user.
Every partial counter is reset to zero when ten thousand count is passed.
All partial counters can be cleared by means a single command; for this purpose the Reset coun-
ters command must be issued available inside the Reset menu.

Fault recording - SFR
Recording
[1]
is triggered by:
• Relay activation (OFF-ON)
• External trigger (binary input) programmed as Fault trigger
• Element start or trip
Twenty events are recorded into a circular FIFO (First In, First Out) buffer.
[2]
Following information are stored in every record (Read \ Faults \ Info menu):
• Fault counter (Faults stored)
[3]
• Last fault
• Date and time (S-Year)
• Date and time (S-Year)
• Date and time (S-Month)
• ...
• Date and time (S-Millisecond
• Fault cause (F-Cause)
• Phase currents (F-IL1, F-IL2, F-IL3, F-IE)
• Residual current I
Er
or I
ECr
• Inputs
• Outputs
• Fault cause info (F-Phases)
The fault log may be erased by means of the command available inside the Read \ Faults \ Reset
menu.
Event recording - Events
Recording is triggered by:
• Power up and/or Power down.
• Element start or trip.
• Binary input switch (OFF-ON or ON-OFF).
• Setting modify.
• Control function trip (TCS OFF-ON or ON-OFF and CB switch OFF-ON or ON-OFF).
One hundred events are recorded into a circular FIFO (First In, First Out) buffer (Read \ Events \ Info
menu).
[4]
Following information are stored in every record (Read \ Faults \ Event menu):
• Event counter (Events stored)
[5]
• Last Event
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 ThyVisor
Note 4 The newest event data are stored inside the event addressed by the Last event parameter (1...100)
Note 5 Counter is updated at any new record; it may be cleared by means ThyVisor
