Multiple parameter monitoring and readout system with sampling of parameters of higher priority than the highest parameter which is out of tolerance

摘要

Apparatus for monitoring and indicating parameter conditions within a system. Signals are generated by sensors which monitor parameter state. The signals are sensed via a multiplexing scheme, each signal being compared to an individually programmed reference. Should a parameter signal exceed the reference, a corresponding indicator is activated. Each parameter is prioritized such that a parameter signal which exceeds its reference will cause the multiplex network to sequentially sense only that parameter and all other parameters of a higher priority. Further refinements allow the readout of the value of a parameter signal if the parameter exceeds its reference or if such readout is manually selected.
