FUNCTION CHARACTERISTICS

be blocked for an adjustable time interval, starting from the starting control criterion (circuit breaker

closure or I

RUN

threshold).

This operating mode may be select by setting

ON-Elementblockingthe I2CLP>Modeand/or

I2CLP>>Mode parameters.

If the CLP function (Cold Load Pick-up) is enabled for threshold change, the selected threshold may

be changed for an adjustable time interval, starting from the starting control criterion (circuit breaker

closure or I

RUN

threshold).

This operating mode may be select by setting

ON-Change setting the I2CLP> Mode and/or

I2CLP>>Mode parameters, whereas the operating thresholds within the CLP may be adjusted

inside the Set \ Proﬁle A (or B) \ Negative sequence overcurrent - 46M \ I2> Element,(I2>> Ele-

ment) \ Deﬁnite time (Inverse time) menus.

For both operating modes the CLP Activation time parameters (

t2CLP>,t2CLP>>) may be adju-

sted inside the Set \ Proﬁle A (or B) \ Negative sequence overcurrent - 46M \ I2> Element (I2>>

Element) \ Setpoints menus.

Starting control

If the CLPSourceparameter is set to IRUN and the maximum value of phase currents is lower than

0.1 I

, the protection is blocked off or the threshold is changed depending on the I2CLP>Mode

and/or I2CLP>>Mode setting.

If the

CLPSourceparameter is set to CB and the circuit breaker is open, the protection is blocked

off or the threshold is changed depending on the

I2CLP>Modeand/or I2CLP>>Mode setting.

The

CLPSourceparameter is common for proﬁles A and B.

For both thresholds the following block criteria are available:

Logical block (Block1)

If the I2>BLK1 and/or I2>>BLK1 enabling parameters are set to ON and a binary input is desi-

gned for logical block (Block1), the concerning element is blocked off whenever the given input is

active.

[1]

The enabling parameters are available inside the Set \ Proﬁle A (or B) \ Negative sequence

overcurrent - 46M \ I2> Element (I2>> Elemen) \ Setpoints menus, while the Block1 function must

be assigned to the selected binary input inside the Set \ Board1(2) inputs \ Binary input IN1-1...INx-x

menus.

Selective block (Block2)

All along the protective elements the 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 input (BLIN1).

• One or more binary inputs designed for input selective block.

• 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 input BLIN1:

• The protection is blocked off according the selectivity block criteria when the input BLIN1 is active.

The information about phase or phase+earth block may be select programming the ModeBLIN1

parameter inside the Set \ Proﬁle A (or B) \ Selective block-BLOCK2 \ Selective block IN menus.

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.

[2]

The enable

I2>BLK2IN and/or I2>>BLK2IN parameters are available inside the Set \ Proﬁle A (or B) \

Negative sequence overcurrent - 46M \ 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 - 46M \ 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.
