Abstract
A monitoring system for use with a conventional actuator system which includes an actuator and control system. The monitoring system comprises a wiring harness including at least three and preferably five ring type current sensors, such as current transformers or Hall effect devices, which are permanently mounted on various leads associated with the control system. The sensors sense currents carried on the leads which are indicative of the state of control system switches connected with the leads. The sensors generate signals responsive to the currents and indicative of the switch states. Each of the sensors is spaced from and wired to a single electrical connector. The connector is adapted to removably mate with a complementary connector to simultaneously electrically couple the complementary connector with each wired sensor. The electrical connector is configured for mounting through a housing to permit simultaneous electrical coupling with each of the sensors of the harness from outside the housing without opening the housing.
