A system for preventing a rack fault condition of a passenger boarding bridge includes a plurality of electromagnetic sensors that are disposed for sensing separately a rotational movement of each one of a first and a second electromechanical screw jack, one electromechanical screw jack located adjacent to each lateral sidewall surface of the passenger boarding bridge. The system also includes a control circuit in communication with the plurality of electromagnetic sensors. The control circuit receives signals from the sensors, which signals are indicative of the sensed rotational movement of each one of the first and second electromechanical screw jacks. A value is determined relating to a rotational synchronization of the first and second electromechanical screw jacks. When the determined value is outside a predetermined range of threshold values, a control signal is provided for affecting the rotational movement of at least one of the first and second electromechanical screw jacks.
