Abstract: A device for monitoring an operating state of a control device of a passenger transport system includes a detection unit for generating a first electrical quantity depending on a signaled state of the control device, an evaluation unit for analyzing the first electrical quantity in relation to the operating state of the control device, and an interface for transmitting a second electrical signal that is dependent on the analysis and is generated in the evaluation unit. The detection unit is a conversion device for converting an optical signal of at least one optical indicator of the control device into the first electrical signal. The device for monitoring allows state information on the control device to be tapped without conversion work being required on the control device.

Abstract: A method for determining a deterioration state in a suspension member arrangement having a suspension member including a plurality of electrically conductive cords includes the steps of: counting a number of bending cycles applied to the suspension member; measuring an electrical characteristic of the suspension member upon applying an electrical voltage to at least one of the cords; performing at least one of (a) determining a critical deterioration state upon monitoring both the bending cycles number and the electrical characteristic, and (b) determining an unexpected deterioration state based on deriving a current actual deterioration state of the suspension member based on the electrical characteristic and assuming a currently expected deterioration state based on the bending cycles number and comparing the current actual deterioration state with the currently expected deterioration state; initiating a defined procedure upon determining at least one of the critical deterioration state and the unexpected deterioration state.
