Abstract

PURPOSE:To detect the full operation states of the driving and braking of an electric car surely and facilitate the discovery of defective places by plural sounds or combin ation of plural sounds. CONSTITUTION:Tap terminal groups 9-14, any of which is pressurized at every stepping of the taps of each notch of motoring and control of an electric car, a motoring check terminal 17 which is pressurized by closing of the notch of an MC handle and is released of pressure by notch-off, a brake checking terminal 16 which is pressurized by placing the brake handle to an electric brake position, an oscillating circuit 7, a speaker SP and an earphone jack EJ are provided. Six kinds of sounds or plural sounds are combined by connecting relays to the terminals 9-14 respectively, connecting the contacts closed by the operation of the corresponding relay in parallel, inserting a resistance of a prescribed value between each contact, making parallel contact circuits connectable to the circuit 7 through the contacts closed by the operation of the relay connecting to the terminal 17 or 16, and connecting the circuit 7 to a tape recorder TR.
