Abstract: An elevator suspension member arrangement includes at least two suspension members having electrically conductive cords. A monitoring arrangement generates first and second alternating voltages phase shifted by 180° and includes a plurality of input connectors and output connectors electrically connected to the cords and a voltage analyzer arrangement analyzing a neutral point voltage resulting from applying the voltages to the cords. Each suspension member can have the cords connected in parallel between the input connector and the output connector or have two groups of the cords connected in series between the connectors with the groups connected to an interconnecting connector. A multiplexer arrangement can be used to selectively test each pair of suspension members when the suspension member arrangement includes more than two suspension members.

Abstract: Methods and devices detect a deterioration state of a load bearing capacity in an elevator suspension member arrangement having several suspension members, such as belts, including electrically conductive cords incorporated into an elastomer material. Deterioration is determined by applying alternating electric voltages to the cords included in legs of a circuitry. Phase shifts between the alternating voltages, for example by determining sum voltages and/or differential voltages, provide valuable information about a condition of the belt. A fixation arrangement of the suspension member arrangement is adapted to enable or simplify the proposed measurements. Furthermore, counting a number of performed bending cycles provides further information to be taken into account for determining the current deterioration state of the belts. Overall, deteriorations in a suspension member such as broken cords, shunts between cords, connections between cords and ground potential and/or deterioration due to corrosion of cords may be easily detected.

Abstract: A method for self-testing a monitoring device monitoring an integrity status of an elevator suspension member arrangement includes the monitoring device having a voltage generation arrangement for generating electric voltages and applying the electric voltages to cords in suspension members of the suspension member arrangement. The monitoring device has a voltage analyzer arrangement for detecting a deterioration in the integrity status based on modifications in the applied electric voltages upon transmission through the cords. The method includes the steps of: specifically modifying the generated electric voltages to systematically induce modifications in the applied electric voltages upon transmission through the cords which, under normal operation conditions of the monitoring device, would be interpreted by the monitoring device as indicating the deterioration in the integrity status; verifying whether the deterioration in the integrity status is correctly detected; and initiating a self-test-failure-action if the deterioration in the integrity status is not correctly detected.

Abstract: A method and device detect non-uniform and uniform deterioration states in an elevator suspension member having first and second groups of electrically conductive cords. First ends of the groups are electrically connected to an alternating voltage generator arrangement and second ends are electrically connected to each other through first and second resistors via a neutral point at which electrical resistances of the groups are the same in a non-deteriorated state of the suspension member. The method includes: applying first and second alternating voltages to the first end of the first and second groups, respectively; determining a neutral point voltage between the neutral point and an electrical reference potential; determining difference voltages between first and second difference measurement points located between the second ends of the groups and the respective resistors; and determining the deterioration state based on both the determined neutral point voltage and the determined difference voltage.

Abstract: A brake system for a passenger transportation system includes a brake lining and a brake surface, wherein a gap exists between the brake lining and the brake surface when the brake system is in an open position. The brake system also includes an optical monitoring system and a processor. The optical monitoring system has a light source arranged to emit light towards at least one of the gap and the brake lining, and a light detector arranged in a light path of the light emitted by the light source. The light detector generates an electrical signal as a function of impinging light. The processor is coupled to the optical monitoring system to receive the electrical signal and to generate a predetermined indication if the signal indicates a value that is equal to or greater than a predetermined threshold value.
