Abstract
A warning system for a printing press to warn the operator upon the exceeding, or departure from, a desired set of running conditions which includes a plurality of remote condition transducers which, in the simplest form of the invention, are in the form of switches. Coupled to the transducers are respective signal generators each of which generates an acoustic signal which has a distinctive quality as compared to all of the other acoustic signals. A loudspeaker common to all of the signal generators is audible at the control station. The distinctiveness of the signal serves to promptly inform the operator which of the running conditions has been exceeded so that corrective action may be taken. In a second embodiment of the invention the transducers produce output control signals which vary in magnitude with the condition, and the corresponding acoustic signal generator produces a signal having a distinctive first quality when the control signal exceeds a threshold level. In addition, each signal generator is made responsive to the magnitude of the control signal for imparting to the acoustic signal a distinctive second quality to a degree which depends upon the departure of the control signal from the threshold level and which is thereby indicative of the degree of urgency.
