5.2 Indication messages
5.2.1 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/
Monitoring/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/
Monitoring/IED status.
The ABB logo together with the IED FAILURE message appear on the screen after
a five minutes' communication break between the LHMI and the IED. The LHMI
panel displays the message due to a communication failure or a severe functional error
in the IED. The protection functionality of the device can be ensured by testing the IRF
contact 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.
