    Fanuc alarms 479 & 486

    Good day, someone could help me?

    I have several alarms: 479 & 486 in a turning machine with 21i-TB control,

    the manual says ILLEGAL SAFETY DI (CNC) AND ILLEGAL SAFETY DI (MNT), turn off the macuine and turn on again, if the alalrms still are on call to Fanuc center,

    Someone have some idea what's the problem?:idea:

    This is caused by a mismatch between PMC and FSSB data used to moniter safety circuits.
