ABSTRACT:
An overspeed control system which is electropneumatic and automatic in its operation is supplied. An engine speed sensing transducer supplies input signals to an electronic monitor which determines if an overspeed condition is about to occur and turns on a warning indicator. If further overspeed condition occurs the monitor supplies an output signal to a solenoid operated air supply control valve which vents high pressure air to a pneumatically operated valve which shuts off the engine air intake. Means are provided for testing the operation of the electronic and pneumatic components of the system independent of the operation of the engine to ensure reliability of the system.
