ABSTRACT:
Provided is a system, a tool and a method for communicating with a faulted circuit indicator (FCI), the faulted circuit indicator including a detection circuit for monitoring an electrical conductor of a power system. The system includes a remote display mounted in a wall of an enclosure and visible from outside of the enclosure and a first light emitting diode associated with the remote display. The first light emitting diode generates an optical FCI status signal in response to an occurrence of a fault in the electrical conductor. The system also includes a first microcontroller operatively coupled to the remote display and the detection circuit, and a handheld user command tool adapted to optically couple with the remote display. The handheld user command tool is also adapted to generate an optical serial communication. The optical serial communication provides data and commands for operation of the faulted circuit indicator.
