<p>An actuator module comprises an actuating unit comprising a solenoid which is capable, when excited, of generating an electromagnetic field, and a core movable due to the electromagnetic field generated by the solenoid with a first end and a second end so as to be able to assume a resting position and an operating position, and which is magnetic and/or able to be magnetized. The actuating unit can be controlled by activation signals and protection signals, the activation signals energizing the solenoid so as to generate a magnetic field such as to move and hold the movable core from a resting position to the operating position, and the protection signals exciting the solenoid so as to generate a magnetic field such as to return the movable core to and hold the moveable core in the resting position. The present invention concerns a locking-unlocking system and method for protecting the system.</p> |
