Abstract: A method determines a status of at least one component of an elevator system, wherein the elevator system includes a suspension apparatus having at least one traction member. The at least one traction member is surrounded by a non-metallic cladding, wherein the suspension apparatus is guided via a drive sheave with a metallic traction surface. The method includes the steps of: identifying at least one parameter based on an electrostatic effect which occurs due to friction of the non-metallic cladding on the traction sheave with the metallic traction surface; and determining a status of the at least one component on the basis of the identified parameter.

Abstract: An elevator has a drive unit displacing an elevator car in an elevator hoistway, an elevator controller controlling operation of the drive unit, multiple safety switches switchable upon occurrence of safety relevant events, and a safety chain overlay control unit including a safety PLC. The PLC has first connectors connected to first safety switch contacts and second connectors connected to second safety switch contacts. The PLC monitors a current safety status of the elevator and identifies a safety critical status by detecting when at least one of the safety switches changes its switching state and comparing the current switching states of the first and second safety switches. The PLC interrupts a main energy supply to the drive unit in response to the safety critical status of the elevator. Comparing switching states of the safety switches connected to the first and second connectors also enables detecting faulty safety switches.

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 system includes a suspension apparatus that has a plurality of tension members in a common jacket. The tension members of the suspension apparatus are electrically interconnected in an electric circuit which includes a current source or a voltage source and a measuring device. The measuring device is connected between a first group of the tension members and a second group of the tension members.

Abstract: A brake of an elevator system is controlled by a brake controller, the brake having an armature that is pulled by an electromagnet to release the brake from a braking position against a spring force into a release position, according to a method including the steps of: applying an initial electrical voltage to the electromagnet and measuring a current intensity then supplied to the electromagnet; and reducing the voltage applied to the electromagnet to a holding voltage in response to a detection of a typical time behavior of the measured current intensity, which detected behavior characteristically occurs when the armature moves from the braking position into the release position. The method allows the brake to be activated more quickly from a released state to a braking state in specific situations.
