Abstract
Systems for monitoring sensed parameters and diagnosing fault conditions are useful in many applications. Advantageously, such systems are capable of operating in a plurality of operating modes and in connection with each of a plurality of machines. In the subject invention, a plurality of gauges are included for indicating the levels of the sensed parameters. A plurality of symbols are included for identifying sensed parameters. A control receives an identification code and selectively illuminates one or more of a plurality of gauges and symbols in response to the identification code. A plurality of warning lights are each associated with a switch-type input. A display selectively indicates a pin code for each switch-type input having a fault condition. The indicator lights having an associated switch-type input in the fault condition are flashed. A device selectively indicates a pin code in response to each diagnosable input having a present or a previous fault condition.
