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).
• BLIN1 pilot wire breaking diagnostic state ON/OFF
• Pilot wire BLIN1 shorted ON/OFF
Selective Block - BLOCK2
The input and output state concerning the selective block are available (Read \ Selective block-
BLOCK2).
Block2 input
• Phase protections input selective block state BLK2IN-Iph ON/OFF
• Ground protections input selective block state BLK2IN-IE ON/OFF
• tB-Iph/IE Elapsed state tB timeout ON/OFF
Block2 output
• Starting state of phase protections enabled
for external selective block on output ST-Iph-BLK2 ON/OFF
• Starting state of ground protections enabled
for external selective block on output ST-IE-BLK2 ON/OFF
• Phase protections output
selective block state BLK2-OUT-Iph ON/OFF
• Ground protections
output selective block state BLK2-OUT-IE ON/OFF
• Phase and ground protections
output selective block state BLK2-OUT-Iph/IE ON/OFF
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)
• Phase currents I
L1r
, I
L2r
, I
L3r
• Residual current I
Er
• Measured residual voltage U
Er
• Displacement angle of measured residual voltage respect to residual current Phi
Er
• Thermal image Dtheta
r
• Negative sequence current I

• Inputs
• Outputs
• Fault cause info (eg. faulted phase)
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
