5.2.3 IRF
The IRF contact functions as an output contact for the self-supervision system of the
protection relay. Under normal operating conditions, the protection relay is energized
and the contact is closed (X100:3-5). When a fault is detected by the self-supervision
system or the auxiliary voltage is disconnected, the output contact drops off and the
contact closes (X100:3-4).
