Reviews For 9905-879
Internal Review

Whenever two of the three speed-sensing circuits in the 9905-879 sense an overspeed condition, the voter relay configuration will change state, causing a turbine trip. It should be noted, however, that a single MPU or circuit failure will not cause an inadvertent trip. - AX Techs
