## Abstract

Elevator components can be equipped with an electronic information plate. The electronic information plates are associated with a particular electronic information plate that can store different properties of the associated component. The content of each electronic information plate is read manually or automatically and transmitted to a controller. The controller analyzes the received content and launches a predetermined action if the content indicates a need for maintenance.

## Claims

### Claim 1

A method for maintenance of an elevator component, the method comprising the steps of:
associating an electronic information plate with an elevator component;
installing the elevator component with the associated electronic information plate;
reading the electronic information plate, wherein the electronic information plate is configured to store information of the elevator component, wherein the information comprises at least one threshold value associated with an action;
transmitting the content of the read electronic information;
comparing the at least one threshold value with elevator counters;
detecting as a result of said comparison if the electronic component has exceeded at least one of the threshold values; and
launching the action associated with the respective threshold value,
wherein the method further comprises the steps of:
counting a threshold value in number of operation cycles; and
counting a threshold value life cycle as a time interval.

### Claim 2 (depends on 1)

The method according to claim 1, wherein when exceeding a first threshold value, the method further comprises the step of transmitting a preliminary warning of an end of life cycle.

### Claim 3 (depends on 2)

The method according to claim 2, wherein when exceeding a second threshold value, the method further comprises the step of limiting operating speed of the elevator.

### Claim 4 (depends on 3)

The method according to claim 3, wherein when exceeding a third threshold value, the method further comprises the step of preventing use of the elevator.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the electronic name plate comprises a component type and the method further comprises the steps of comparing the component type and the elevator type and transmitting a warning message when an incompatible component type is detected.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the elevator component is one of the following: a suspension rope, a suspension belt, a traction rope or a traction belt.

### Claim 7 (depends on 1)

The method according to claim 1, further comprising the step of transmitting the content of the read electronic information plate into an elevator controller.

### Claim 8 (depends on 1)

The method according to claim 1, further comprising the step of transmitting the content of the read electronic information plate into an external computing device.
