ABSTRACT:
A monitor and governor circuit provides speed control for an engine. The governor portion of the circuit, principally a PID controller, includes a fail safe circuit to shut the engine down in the absence of signals related to engine RPM. In addition, the governor includes a high gain feature operable during start up to keep the integrator from saturating. The speed monitor portion of the circuit prevents engine damage in the event that the speed governor should fail as, for example, due to a shorted output transistor or an open speed setting potentiometer. The end user is not required to set the speed monitor since it can be preset to a selected percent of the governor set speed.
