    Abstract: The invention relates to a method for resetting a safety mode of an elevator system. The safety mode is caused by a power cycle of the elevator system. The method comprises: obtaining, upon a restoration of a power supply of the elevator system, status information indicative of a current safety status of at least one safety space of the elevator system from an elevator safety detection system; receiving, from a remote elevator service entity, a reset command comprising an instruction to reset the safety mode of the elevator system; and resetting the safety mode of the elevator system in response to receiving the reset command, if the obtained status information fulfills a predefined criterion. The invention relates also to an elevator safety control unit, a remote reset system, a computer program, and a computer-readable storage medium for resetting a safety mode of an elevator system.

    Abstract: An elevator system includes a hoistway with marking objects arranged at predetermined positions in the hoistway, an elevator car with a sensor providing an indication when the elevator car has reached the position a marking object, a complementary positioning system providing a complementary indication of the position of the elevator car in the hoistway, and a controller receiving the indication and the complementary indication. In order to minimize a need for manual inspections, the controller includes a memory maintaining for each marking object a setup position, and during elevator runs, the controller is configured to calculate an offset for a marking object for which the sensor provides an indication, by comparing the setup position for the marking object in question with the position indicated by the complementary positioning system at the indication of the marking object, and to trigger an alarm if the calculated offset fulfills a predetermined criterion.
