Indication Explanation1 I> START = The low-set stage I> of the overcurrent unit has started
2 I> TRIP = The low-set stage I> of the overcurrent unit has operated
3 I>> START = The high-set stage I>> of the overcurrent unit has started
4 I>> TRIP = The high-set stage I>> of the overcurrent unit has operated
5 I0> START = The low-set stage I0> of the earth-fault unit has started
6 I0> TRIP = The low-set stage I0> of the earth-fault unit has operated
7 I0>> START = The high-set stage I0>> of the earth-fault unit has started
8 I0>> TRIP = The high-set stage I0>> of the earth-fault unit has operated
9 CBFP = Circuit breaker failure protection has operated
D) The TRIP indications persist when the protection stage returns to normal. The indicator is reset by pushing the RESET/STEP
push-button.
Further, the indicators may be reset via the
external control input 10-11 by applying a
control voltage to the input, provided switch
SGB/8 is in position 1.
The basic protection relay functions are not
depending on the state of the operation indicators, reset or non-reset. The relay is permanently
operative.
If a protection stage starts, but not operates,
because the energizing quantity goes below the
set start current before the operate time circuit
has timed out, the start indicators are normally
automatically switched off. However, by means
of the switches SGF2/1…4 the start indications
may be made persistant which means that they
are to be manually reset by pushing the RESET/
STEP push-button. The persistent indications
are obtained through the following switch settings.

SGF2/1 = 1 manual reset of I> start indication
SGF2/2 = 1 manual reset of I>> start indication
SGF2/3 = 1 manual reset of I0> start indication
SGF2/4 = 1 manual reset of I0>> start indication
On delivery of the relay from the factory the
switches SGF2/1…4 are preset at 0.
E) Shortly after the internal self-supervision
system has detected a permanent relay fault
the red IRF indicator is switched on and the
output relay of the self-supervision system
operates. Further, in most fault situations an
autodiagnostic fault code is shown in the
display. The fault code is composed of a red
figure 1 and a green code number which
indicates fault type. The fault code persists
until the STEP/RESET push-button is
pressed. When a fault code appears on the
display, the code number should be recorded
for statistical and maintenance purposes.
