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 numbers 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.

operates relay R1,R2,R3,R4
tRI
-
-
-
- Start of reclose timer tRI
operates relay R1,R2,R3,R4
tBF
-
-
-
- Breaker failure element
operates relay R2,R3,R4
tFRes
: M
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

i
The input for blocking the operation of the time delayed elements relevant to phase faults
(IL, IH, OL, OH) can act on the function (IL) only, (OL) only, (IH) only or (OH) only, or on both.
(i = IL, I = IH, o = OL, O = OH)
Bo
-u
The input for blocking the operation of the time delayed elements relevant to unbalance (UH, UL) can
act on the function (U=UH) only or (u=UL) only, or on both
tBf
2tBF
The blocking of the phase fault elements can be programmed so that it lasts as long the blocking input
signal is present (tBIf Dis) or (tBf 2xtBf); even with the blocking input still present, it only lasts for the
set trip time delay of the function plus an additional time 2xtBf
tBo
2tBF
As above for the unbalance functions

- 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
