a)
Can be corrected by restoring factory settings for CPU.
b)
All settings will be zero during the fault.
For further information on internal relay faults, refer to the Operator’s Manual.
Warnings
In case of a warning, the relay continues to operate except for those protection
functions possibly affected by the fault, and the green target LED (ready) remains lit
as during normal operation. Further, a fault target message, which depending on the
type of fault includes a fault code, appears on the LCD. If more than one type of
fault occur at the same time, one single numeric code which indicates all the faults is
displayed. The fault target message cannot be manually cleared but it disappears
with the fault.
When a fault appears, the fault target message is to be recorded and stated when
ordering service. The fault codes are listed in the following table:
