This is a read-write field controlling under what condition feed shelf Ft1 will proactively turn off a circuit: never (disabled), once it's faulted, or once it's faulted and carrying no load (faultedAndNoLoad). It lets an admin balance safety against availability, for example only shedding a circuit once it's both broken and useless rather than cutting it the instant a fault appears. For example, setting cps6000Ft1Tof to faultedAndNoLoad(2) makes Ft1 only shut down a faulted circuit once it also confirms nothing is actually drawing power from it.
