摘要:
A monitoring arrangement of an elevator and to a method for monitoring an elevator. The monitoring arrangement of an elevator comprises a drop-out safety device of the elevator, an elevator component, which is in operational connection with the drop-out safety device of the elevator, a measuring device, with which the operation of the aforementioned elevator component is measured, and also a monitoring unit, comprising an input for the measuring data of the aforementioned measuring device as well as a memory for setting one or more boundary conditions to be connected to the safe operation of the elevator component. The monitoring unit is configured to receive measuring data from the aforementioned measuring device and also to determine that the operating safety of a drop-out safety device of the elevator is endangered if the measuring data received does not fulfill the boundary conditions set for the safe operation of the elevator component.

The invention relates to a method and an apparatus the invention is a method for automatic configuration of an elevator drive in a traction elevator comprising an elevator car, a counterweight, a traction sheave, an electrical motor and a plurality of elevator ropes arranged to hoist the elevator car in response to the electrical motor rotating the traction sheave. The method comprises obtaining a plurality of electrical motor parameters from a memory associated with the electrical motor. A drive computer unit determines a roping ratio of the elevator by driving the elevator a distance based on elevator position sensor information and determines a plurality of torque values required to hoist the elevator with a predefined starting acceleration when the elevator car is loaded with a respective plurality of different loads. The torque values per each load are stored to a memory of the drive computer unit.

In the method for increasing the availability of an elevator standing unused at a landing the ambient temperature of at least one electrical device of the elevator is measured; and when the ambient temperature falls below a threshold value, electric current is conducted to at least one electrical device of the elevator for warming the electrical device in question. The patent application also includes an independent claim for a system for increasing the availability of an elevator standing unused at a landing.
