86 Power supply module unknown
90 Hardware configuration error
95 Communication module unknown
104 Faulty configuration set (for IEC 60870-5-103)
131, 139, 195, 203, Internal reference voltage error
222, 223
253 Error in the measuring unit
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 indicator LED (ready)
remains lit as during normal operation. Further, a fault indication 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 indication message cannot be manually
cleared but it disappears with the fault.
When a fault appears, the fault indication message is to be recorded and stated when
ordering service. The fault codes are listed in the following table:
Table 5.1.18.-2 Warning codes
