FUNCTION CHARACTERISTICS
Use of binary inputs:
• If the I2>BLK2IN and/or I2>>BLK2IN parameters are set to ON and a binary input is desi-
gned for selective block (Block2), the protection is blocked off by phase elements (Block2 Iph)
or by any protection element (Block2 Iph/IE) according the selectivity block criteria.

The enable
I2>BLK2IN and/or I2>>BLK2IN parameters are available inside the Set \ Profile A (or B) \
Negative sequence overcurrent - 46LT \ I2> Element (I2>> Element) \ Setpoints menus, while the
Block2 Iph and
Block2Iph/IE functions must be assigned to the selected binary inputs inside
the Set \ Board 1(2) inputs \ Binary input IN1-1...(IN1-x) menus.
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:
• If the I2>BLK2OUTand/orI2>>BLK2OUT enable parameters are 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 protection element (BLK2OUT-Iph/IE), whenever the given element (Start
I>, Start I>> e/o Start I>>>) becomes active. The enable
I2>BLK2OUTand/orI2>>BLK2OUT
parameters (ON or OFF) are available inside the Set \ Profile A (or B) \ Negative sequence over-
current - 46LT \ I2> Element (I2>> Element) \ Setpoints menus, 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) \ Selecti-
ve block-BLOCK2 \ Selective block OUT menu.
All parameters can be set separately for A and B setting profiles.
