Brake signal transmitter 480 001/ 002 ... 0 The brake signal transmitter is used to produce electrical and pneumatic signals, and to increase and decrease the air pressure of the electronically controlled braking system. The device has a dual-circuit pneumatic and a dual-circuit electrical structure. Actuation start is record- ed electronically by a double switch. The operating tap- pet’s route is controlled and transmitted as pulse-width modulated electrical signal. Further pneumatic redun- dancy pressure is delivered in circuits 1 and 2. The pressure in the second circuit is retained slightly in the process.
In case of (electrical or pneumatic) failure of a circuit, the other circuits remain functional. Depending on bus type, the brake signal transmitter is actuated via a running plate (480 002 ... 0) 0) or via a push pedal using the tappet (480 001 ... 0).
