Self test
Lower level diagnostic (MINOR) can be output or ignored; for this purpose the MINOR Fail alarm
parameter can be set ON or OFF inside the Set\Self test relay submenu.
Following anomalies (MINOR) are not relevant (the protective elements continue to work):
• Errors concerning the digital fault recorder.
• Internal bus.
The self test information are:
• Protection and controls ON SERVICE/OUT OF SERVICE
• System diagnostic OK/NOT OK
• Device diagnostic OK/NOT OK
• Program diagnostic OK/NOT OK
• Data-base boot OK/NOT OK
• Data-base runtime OK/NOT OK
• DSP boot OK/NOT OK
• DSP run-time OK/NOT OK
• Memory boot OK/NOT OK
• Memory run-time OK/NOT OK
• Data Bus heavy OK/NOT OK
• Data Bus minor OK/NOT OK
• Oscillography run-time OK/NOT OK
• PLC boot OK/NOT OK
• PLC run-time OK/NOT OK
• Protection I/O assigned verify startup OK/NOT OK
• Protection I/O assigned verify run-time major OK/NOT OK
• Protection I/O assigned verify run-time minor OK/NOT OK
• Total protection I/O assigned not-matching 0
• Protection I/O assigned not-matching
• PLC I/O assigned not-matching OK/NOT OK
• PLC I/O assigned not-matching run-time major OK/NOT OK
• PLC I/O assigned not-matching run-time minor OK/NOT OK
• Total PLC I/O assigned not-matching 0
• PLC I/O assigned not-matching
• MMI module Boot OK/NOT OK
• MMI module Run-time OK/NOT OK
• MRI module Boot OK/NOT OK
• MRI module Run-time OK/NOT OK
• MID16-1 module Boot OK/NOT OK
• MID16-1 module Run-time OK/NOT OK
• MID16-2 module Boot OK/NOT OK
• MID16-2 module Run-time OK/NOT OK
• PT100 module Boot OK/NOT OK
• PT100 module Run-time OK/NOT OK
• Current loop module Boot OK/NOT OK
• Current loop Run-time OK/NOT OK
• Oscillography run-time OK/NOT OK
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 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.
[1][2]
Following information are stored in every record:
• Fault counter
[3]
• Date and time
• Fault cause (element trip)
• Input voltages U
L1r

L2r
, U
L3r
• Measured residual voltage U

• Calculated residual voltage U
ECr
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
