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: An elevator suspension member arrangement includes a monitoring arrangement monitoring an integrity status of suspension members having electrically conductive cords. The monitoring arrangement includes: a generator generating phase shifted first and second alternating voltages; input and output connectors each establishing electrical contacts to cords in one of the suspension members; a voltage analyzer measuring and analyzing a neutral point voltage resulting from applying the first and second alternating voltages to first and second cords of the one suspension member; a supply circuitry having supply lines electrically interconnecting the generator with the input connectors; and a measurement circuitry including measurement lines electrically interconnecting the analyzer with at least one of the input connectors and the output connectors. The supply and measurement lines are separated from each other whereby disturbing influences of impedances through the supply circuitry is minimized due to voltage measurements being performed through the separate measurement circuitry.

Abstract: A suspension member arrangement for an elevator includes a suspension member having a plurality of electrically conductive load-bearing cords commonly embedded in an electrically isolating matrix material, a first connector and a second connector each attached to the suspension member and electrically contacting the cords within the suspension member in a contacted end region thereof. The first connector electrically contacts and electrically interconnects in parallel a first group of the cords being a first plurality of directly neighboring ones of the cords. The second connector electrically contacts and electrically interconnects in parallel a second group of the cords being a second plurality of directly neighboring ones of the cords. The suspension member arrangement facilitates electrically contacting the cords of the suspension member using a simple type of connector whereby deteriorations in characteristics of the suspension member can be electrically detected with high accuracy.

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: A method for detecting a deterioration state in an elevator suspension member including electrically conductive cords uses a multiplexing unit (MU) to apply first and second alternating voltages to proximal ends of first and second groups of the cords respectively and connect the proximal end of a third group of the cords to a voltage measurement arrangement connected to a reference potential. Distal ends of the groups are connected together. A first neutral point voltage between the third proximal end and the reference potential is determined. The MU is switched to apply the first alternating voltage to the second proximal end, apply the second alternating voltage to the third proximal end and determine a second neutral point voltage between the first proximal end and the reference potential. The deterioration state of the suspension member arrangement is determined based on the first and second neutral point voltages.

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.
