Self-supervision (IRF) system

The relay is provided with an extensive self-supervision system which continuously
supervises the software and the electronics of the relay. It handles run-time fault
situations and informs the user about an existing fault via a LED on the HMI and a
text message on the LCD. There are two types of fault indications: IRF indications
and warnings.
