ABB Relion 670 series, Installation And Commissioning Manual

• Self-supervision summary = INT--FAIL and INT--WARNING
• CPU-module status summary = INT--NUMFAIL and INT--NUMWARN
When an internal fault has occurred, extensive information about the fault can be
retrieved from the list of internal events available in the SMS part:
TRM-STAT TermStatus - Internal Events
The list of internal events provides valuable information, which can be used during
commissioning and fault tracing.
The internal events are time tagged with a resolution of 1ms and stored in a list.
The list can store up to 40 events. The list is based on the FIFO principle, when it is
full, the oldest event is overwritten. The list cannot be cleared and its content
cannot be erased.
The internal events in this list not only refer to faults in the IED, but also to other
activities, such as change of settings, clearing of disturbance reports, and loss of
external time synchronization.
The information can only be retrieved from the Parameter Setting software
package. The PC can be connected either to the port at the front or at the rear of the
IED.
These events are logged as internal events.
