FUNCTION CHARACTERISTICS
(L)” in relevant BF menus[1]:
• Set \ Profile A (or B) \ Breaker failure - BF side H
• Set \ Profile A (or B) \ Breaker failure - BF side L
The following block criteria are available:
Logical block (Block1)
If the 64REF-BLK1 enabling parameter is set to ON and a binary input is designed for logical block
(Block1), the element is blocked off whenever the given input is active.
[2]
The enabling parameters
are available inside the menu Set \ Profile A (or B) \ Low impedance restricted ground fault - 64REF
menu, while the Block1 function must be assigned to the selected binary input inside the Set \ Bo-
ard1(2) inputs \ Binary input IN1-1...INx-x) menus.
Selective block (Block2)
For the protective element the output selective block may be set.
The logic selectivity function may be performed by means any combination of the following I/O:
• One committed pilot wire output (BLOUT1).
• One or more output relays designed for output selective block.
Only when the committed pilot wire are used the continuity check of the pilot wire link is active.
Use of committed pilot wire output BLOUT1:
• The information about phase or phase+earth block may be select programming the ModeBLOUT1
parameter (
OFF-ONIPh-ONIPh/IE-ONIE) inside Set \ Profile A (or B) \ Selective block-
BLOCK2 \ Selective block OUT menus.
Use of output relay (K1...K6):
• If the 64REF-BLK2OUT enable parameter is set to ON and a output relay is designed for selective
block (Block2), the protection issues a block output by phase elements (BLK2OUT-Iph) or by any pro-
tection element (BLK2OUT-Iph/IE), whenever the given element (Start 64REF) becomes active. The
enable
64REF-BLK2OUTparameter (ON or OFF) is available inside the Set \ Profile A (or B) \ Low
impedance restricted ground fault - 64REF, while the
BLK2OUT-Iph-K, BLK2OUT-Iph/IE-K
and/or BLK2OUT-IE-K output relays and LEDs (BLK2OUT-Iph-L, BLK2OUT-Iph/IE-L e/o
BLK2OUT-IE-L) must be select inside the Set \ Profile A (or B) \ Selective block-BLOCK2 \ Se-
lective block OUT menu.
Note 1 The common settings concerning the Breaker failure protection are adjustable inside the Breaker Failure - BF menu.
Note 2 The exhaustive treatment of the logical block (Block 1) function may be found in the “Logic Block” paragraph inside CONTROL AND MONITOR-
