Abstract
Abstract A system for providing an indication of a remote condition, as a cycle of a machine. A transmitter coupled to the machine operates to separately sense different conditions of the machine and transmits separate signals corresponding to the sensed conditions of the machine. The signals are carried via the conventional electric power distributing lines to a receiver and indicator apparatus. The indicator apparatus functions to selectively sense the signals from the receiver to provide a visual indication of the sensed condition of the machine.
