Abstract

A fault indication signal from a plurality of sensors is used to advance a rotary switch to hunt in search of the terminal at which the signal appears. The terminals of the switch are associated with the corresponding visual fault indications recorded on an endless film mounted on a transport mechanism that is driven in unison with the rotary switch. Upon the occurrence of a second fault, the switch is again triggered to advance in search of the terminal where the second signal appears for successive indication of the second fault location. The switch is automatically stepped to a terminal where a signal indicating the presence of more than one fault appears for permanent indication of the number of such faults. The system can be restarted manually to provide successive indications of the first and second faults to facilitate troubleshooting.
