ABSTRACT:
A system for giving warning of the existence of an undesirable state of one or more of a plurality of monitored operating conditions of an engine-powered vehicle. Three degrees of warning are given, depending upon the criticality of the monitored condition. Individually energizable low-intensity warning indicators are provided for each of the monitored conditions, and a multiplexing circuit is provided for staggered pulsing of these indicators. The existence of any critical fault will cause an intermittent operation of a more intense warning device, while the existence of a highly critical fault will give an additional intermittent warning of a still greater degree of intensity.
