The yellow operation indicator is lit as soon as
one of the stages of the relay operates and has
activated its control output. When the stage re-
sets, the yellow LED is reset as well.

The IRF LED indicates internal relay fault. The
indicator is lit about 1 minute after the self-su-
pervision system has detected a permanent fault.
At the same time as the LED goes on the relay
module delivers a control signal to the output
relay of the self-supervision system. In most cases

The leftmost red digit on the display has two
functions: on one hand, it serves as address in-
dicator for different types of data and, on the
other hand, as operation indicator of the two
stages of the synchro-check relay. Operation is
indicated by a red digit, 1 or 2, depending on
which of the stages that activated its close sig-
nal.
The red digits 3, 4, 5 and 6 indicate an abnor-
mal situation at command mode operation.
These alarm indicators remain lit even when the
situation returns to normal, and have to be re-
set by pressing the reset push-button. A non-
reset operation indicator does not affect the
operation of the relay module, which is always
alert. The following table, which is printed on
the relay's front plate under the name OPER.
IND., explains the code numbers of the opera-
tion indicators.
a fault code that shows the nature of the fault
appears on the display of the relay module. This
fault code that consists of a red digit 1 and a
green code number cannot be reset from the
display. The code should be recorded to facili-
tate service.
