Patent ID: 8684305

Claim:
A device for controlling power supply of at least one aircraft maintenance actuator from an electrical power supply network of the aircraft, comprising: control means for controlling the electrical power supply of at least one maintenance actuator and means for establishing communication between the control means and at least one control unit allowing a user to control the operation of the at least one maintenance actuator, wherein the at least one control unit comprises a first control button which when it is depressed, corresponds to the sending of a command to move the maintenance actuator in a direction causing the opening of a cowling, and a second button which when it is depressed, corresponds to the sending of a command to move the maintenance actuator in a direction causing the closing of the cowling, the control means being arranged to compare states of the first and second control buttons, with: a reference state in which the first control button and the second control button are in its rest position and for which powering up of the actuator can be authorized by the control means when the power supply network is powered up, a first abnormal state in which the first control button is depressed and the second control button is in its rest position, for which the powering up of the actuator is blocked when the power supply network is powered up, a second abnormal state in which the first control button is in its rest position and the second control button is depressed, for which the powering up of the actuator is blocked when the power supply network is powered up, and a third abnormal state in which the first control button is depressed and the second control button is depressed, for which the powering up of the actuator is blocked when the power supply network is powered up.
