8.2 Indication messages
8.2.1 Internal faults
When the Ready LED indicates an internal fault by flashing, the message associated with
the fault is found in the internal event list in the LHMI menu Main menu/Diagnostics/
Internal events. The message includes the date, time, description and signal state for the
fault. The internal event list is not updated dynamically. The list is updated by leaving the
Internal events menu and then selecting it again. The current status of the internal fault
signals can also be checked via the LHMI in Main menu/Diagnostics/IED status.
Different actions are taken depending on the severity of the fault. If the fault is found to
be permanent, the IED stays in internal fault mode. The IED continues to perform internal
tests during the fault situation.
When a fault appears, the fault indication message is to be recorded and stated when
requesting support or service.
