4. SIGNALIZATIONS
Eight signal leds (normally off) are provided:
a)
Red LED
IL
(OVERLOAD)
 Flashing when measured current exceeds the set pick-up IL.
 Illuminated on trip after expiry of the set trip time delay tIL.
b) Red LED
IH
(PHASE FAULT)
 Same as above related to IH and tIH.
c)
Red LED
OL/OH
(EARTH FAULT)
 Flashing when Earth Fault current exceeds the pick-up level OL or OH.
 Illuminated on trip of the time delayed element tOL or tOH.
d) Red LED
UL/UH
(UNBALANCE)

Flashing when the UNBALANCE voltage exceeds the pick-up level UL or UH
 Illuminated on trip of the time delayed element tUL or tUH.
e) Yellow LED
PROG/IRF
 Flashing during the programming of the parameters
 Lit-on in case of Internal Relay Fault.
f) Red LED
I

(RECLOSE
INHIBIT)
 Flashing when the current drops below the set level I

.
 Illuminated on trip after expiry of the set trip time delay tI

; the led
automatically extinguishes at the end of the set wait time for enabling to
reenergize the capacitor bank.
g) Red LED BR. FAIL.
 Flashing during the reclose inhibition time tRI
 Lit-on when the BREAKER FAILURE function is activated.
h) Yellow LED
B.I./F.D.
(FUNCTION
DISABLED)
 Illuminated when the operation of one or more of the relay functions has
been disactivated in the programming
 Flashing when a block signal is present.
The reset of the leds takes place as follows

Leds a,b,c,d,g

From flashing to off, automatically when the lit-on cause disappears

From ON to OFF, by "ENTER/RESET" push button only if the
tripping cause has disappeared.

Leds e,f,h

From ON to OFF, automatically when the lit-on cause disappears.
In case of auxiliary power supply failure the status of the leds is recorded and reproduced when power
supply is restored.
