12.2 - PROGRAMMING THE CONFIGURATION OF OUTPUT RELAYS
Mode PROG menu F
RELAY (Production standard settings here under shown).
The key "
+
" operates as cursor; it moves through the digits corresponding to the four programmable
relays in the sequence 1,2,3,4,(1= relay R1, etc.) and makes start flashing the information actually
present in the digit. The information present in the digit can be either the number of the relay (if this was
already associated to the function actually on programming) or a dot (-) if the relay was not yet
addressed.
The key "
-
" changes the existing status from the dot to the relay number or viceversa.

Description
I>
--3- Instantaneous element of low-set overcurrent
(only one or more, whatever combination)
operates relays R1,R2,R3,R4.
tI>
1--- As above, time delayed element.
operates relay R1,R2,R3,R4.
I>>
--3- Instantaneous element of high-set overcurrent
operates relay R1,R2,R3,R4.
tI>>
1--- As above, time delayed element.
operates relay R1,R2,R3,R4.
O>
---4 Instantaneous element of low-set earth fault element
operates relay R1,R2,R3,R4.
tO>
-2-- As above, time delayed element.
operates relay R1,R2,R3,R4.
O>>
---4 Instantaneous element of high-set earth fault element
operates relay R1,R2,R3,R4.
tO>>
-2-- As above, time delayed element.
operates relay R1,R2,R3,R4.
So>
---4 Instantaneous element of Sensitive earth fault element
operates relay R1,R2,R3,R4.
tSo>
-2-- As above, time delayed element.
operates relay R1,R2,R3,R4.
I
2
>
--3- Instantaneous element of Negative Sequence O/C
element
operates relay R1,R2,R3,R4.
tI
2
>
1--- As above, time delayed element.
operates relay R1,R2,R3,R4.
tFRes
: A
The reset after tripping of the relays associated to the time delayed elements can take
place:
(A)
automatically when current drops below the trip level.
(M)
manually by the operation of the "ENTER/RESET" key.
Bf
-Ii
The input (Bf) can block the operation of one or more of the time delayed O/C element,
N
= Negative Sequence O/C (I
2
>),
i
= low-set O/C (I>),
I
= High-set O/C (I>>)
Bo
-Oo
The input (Bo) can block the operation of one or more of the time delayed E/F element,
S
= Sensitive E/F (So),
o
= low-set E/F (O>),
O
= High-set E/F (O>>)
tBf
2tB0
The blocking of the phase fault elements can be programmed so that it lasts as long as
the blocking input signal is present (tBf Dis) or so that, even with the blocking input still
present, it only lasts for the set trip time delay of the function plus an additional time 2xtBO
(tBf 2xtBO).
tBo
2tB0
As above, for the earth fault elements (tBo Dis) or (tBo 2tBO).
I>
- 2 - 4
This dash means
that output relay
number 1 is not
assigned to this
element
This is the name of
protective element
The number 2
means that
output relay 2 will
operate when
this element trips
This dash means
that output relay
number 3 is not
assigned to this
element
The number 4 means
that output relay 4 will
operate when this
element trips
