Warning
In case of a less severe fault (warning), the relay continues to operate except for
those protection functions possibly affected by the fault. At this type of fault, the
green target LED remains lit as during normal operation, but the text WARNING
with a fault code or a text message indicating the fault type replaces the name of the
feeder on the display in the idle mode. Some of these faults can be corrected by a
relay operator at site. After the fault has disappeared or been corrected, the message
is automatically cleared.
WARNING
BATTERY LOW

Fig. 4.3.2.3.-2 Warning with text message
If more than one type of fault occur at the same time, one single numeric code which
indicates all the faults is displayed. For instance, 2049 implies two faults: the
battery is low and the temperature sensor RTD6 is faulty. The code is composed of
the weighting factors assigned to each fault type as follows: 1 + 2048; see
