ABSTRACT:
Operational diagnostic system for an angle detector (C) which measures the angle of a rotating part (2) via at least two dual-state logic signals (A, B) processed by an electronic device which encodes them as the weighted sum of their voltages in order to produce an analog signal at a voltage which is always greater than a predefined threshold when angle detector (C) functions normally, in such a way that the value of the measured angle is transmitted over a single electrical connection (S) connecting the output of angle detector (C) to a processing device (U) of the processor type, and the connection (S) is also used by the processing device (U) to transmit the command signal to start testing of the operation of the detector (C), and to transmit the result information from the detector (C) to the processing device (U), and features the following:
