Self-supervision
The IED's extensive self-supervision system continuously supervises the software and the
electronics. It handles run-time fault situation and informs the user about a fault via the
LHMI and through the communications channels.
There are two types of fault indications.
• Internal faults
• Warnings
3.2.1
Internal faults
When an IED internal fault is detected, the green Normal LED begins to flash and the
self-supervision output contact is activated.
An indication about the fault is shown as a message on the LHMI. The text
Internal
Fault
with an additional text message, a code, date and time, is shown to indicate the
fault type.
Different actions are taken depending on the severity of the fault. The IED tries to
eliminate the fault by restarting. After the fault is found to be permanent, the IED stays in
internal fault mode. All other output contacts are released and locked for the internal fault.
The IED continues to perform internal tests during the fault situation.
If an internal fault disappears, the green Normal LED stops flashing and the IED returns
to the normal service state. The fault indication message remains on the LCD until
manually cleared.
