<p>PURPOSE:To switch use and nonuse of automatic idling function by connecting a quasi-load circuit for adding a quasi-current to a load current detector in an interruption enabling manner. CONSTITUTION:The rotating speed of a generator 2 is detected by a rotating speed detector 6, the load current of the generator is detected by a load current detector 7, and the detection signals are respectively input to a controller 4. The controller 4 outputs a control signal to a drive circuit 8 on the basis of the input signals and the contained program, and controls the opening of a throttle valve 5. When a quasi-load circuit 10 is connected with the detector 7, the quasi-current of the prescribed amplitude is applied to the detector 7 to set the automatic idling function to unused state.</p> |
