D) The TRIP indications persist when the pro-
tective stage returns to normal. The indicator is
reset by pushing the RESET/STEP push-button.
Further, the indicators may be reset via the ex-
ternal control input 10-11 by switching a con-
trol voltage to the input, provided that the
microswitch SGB/8 is in position 1.
The basic protective relay functions are not de-
pending on the state of the operation indica-
tors, reset or non-reset. The relay is permanently
operative.
If a protective stage starts, but no tripping oc-
curs because the energizing quantity goes be-
low the starting level before the delay circuit
times out, the starting indicators are normally
automatically switched off. However, by means
of the switches SGF2/1...4 the starting indica-
tions may be made persistant which means that
they are to be reset by pushing the RESET/
STEP push-button.

A) The operation indicator TRIP is switched
on when one of the protective stages operate.
When the protective stage resets, the red indi-
cator remains alight.
B) If the display is dark when one of the pro-
tective stages I>, I>>, I

dicated with a yellow LED. If, for instance, the
TRIP indicator glows red, and the indicators

overcurrent has occurred on phase L1 and L2.
C) Besides being a code number at data presen-
tation, the leftmost red digit or the display serves
as a visual function indicator. A function indi-
cator is recognized by the fact that the red digit
alone is switched on. The following table named
OPERATION IND. is a key to the function
code numbers used.

The persistent indications are obtained through
the following programming.
Switch SGF2/1 = 1
Starting indication on I> persistent
Switch SGF2/2 = 1
Starting indication on I>> persistent
Switch SGF2/3 = 1
Starting indication on I
Switch SGF2/4 = 1
Starting indication on I
On delivery from the factory the switches SGF2/
1...4 have the preset configuration 0.
E) Shortly after the internal self-supervision sys-
tem has detected a permanent relay fault the red
IRF indicator is switched on and the output re-
lay of the self-supervision system operates. Fur-
ther, in most fault situations a 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 what may be the fault
type.The fault code can not be reset as long as
the fault persists. When a fault code appears on
the display, the code number should be recorded
on a piece of paper and given to the authorized
repair shop when overhaul is ordered.
