    摘要: After the control system has been started, which system has two control paths that are used as alternatives for delivering a control electric current to an electrohydraulic member for transforming said current into hydraulic power that is delivered to the actuator, and before powering a starter-generator of the engine, the detection method comprises implementing the following steps for each of the control paths in succession: delivering a predetermined test electric current over said path; evaluating a difference between the test electric current and a measurement of the electric current as transformed into hydraulic power by the electrohydraulic member; and if said difference is greater than a predefined threshold, detecting an electrical failure on said path.

    摘要: In a testing overspeed protection system: a) on receiving an order to start a turbomachine, an electronic regulation system (ERS) of the turbomachine sends an order to a control circuit of a fuel cutoff member to close the fuel cutoff member or to keep it in the closed position; b) the closed state of the FCM is verified on the basis of information transmitted to the ERS and representative of the position of the FCM; c) if the result of the verification in b) is positive, the ERS sends an order to the FCM control circuit to authorize opening of the FCM and enable the starting procedure to continue; and d) if the result of the verification in b) is negative, the ERS issues fault information concerning the overspeed protection system.
