Method for controlling a signalling device inserted in an automatism of gates (G), movable barriers, doors or the like, and having at least one warning device (L, BZ), characterised in that it supplies power from the signalling device (LL) to at least one mechanical group (M) having a motor, detects in the signalling device (LL) the absorbed power from the at least one mechanical group (M) having a motor, and activates the at least one warning device (L, BZ) when the predefined absorbed power threshold has been exceeded. |
