<p>The method involves executing a test procedure for determining whether the presence of a voltage on phase terminals (P1, P2) is due to a dysfunction of a control point (CSW), in case of detection of the voltage on the terminals. The test procedure is performed by supplying an induction motor (MOT) by one of the phase terminals having the lowest voltage and measuring an electric amplitude at the level of the phase terminal, during the supplying operation. The dysfunction of the control point is concluded or not based on the evolution of the electrical amplitude during its measurement stage. An independent claim is also included for an actuator with motor and phase terminals connected to a phase conductor of an electric supply source by using a control point.</p> |
