4.4.9 FIELD-BREAKER DISCREPANCY
PATH: SETPOINTS ÖØ S3 DIGITAL INPUTS ÖØ FIELD-BKR DISCREP.
The field-breaker discrepancy function is intended for use with synchronous generators. If a digital input is assigned to this
function, any time the field status contact indicates the field is not applied and the breaker status input indicates that the
generator is online, a trip will occur once the time delay has expired. The time delay should be used to prevent possible nui-
sance tripping during shutdown. The field status contact may be chosen as "Auxiliary a", open signifying the field breaker or
contactor is open and shorted signifying the field breaker or contactor is closed. Conversely, the field status contact may be
chosen as "Auxiliary b", shorted signifying the field breaker or contactor is open and open signifying it is closed.
