Generating elevator or escalator installation fault log
First Claim
1. A method of maintaining an elevator or escalator installation with a display and control unit coupled to an interface of the installation, comprising the steps of:
- a. coupling the display and control unit to the installation, identifying the installation to the display and control unit, transmitting operating parameters of the installation to the display and control unit, establishing a data connection between the display and control unit and a maintenance center located remotely from the installation, requesting data and parameters of the installation which are transferred to the display and control unit, and ascertaining operating faults of the installation on the display and control unit by a test routine in dependence on a comparison between the operating parameters and the transferred data and parameters;
b. associating at least one of the components of the installation with the respective ascertained operating fault;
c. identifying each of the components of the installation associated with the respective ascertained operating fault; and
d. producing a fault log with a specification of the ascertained operating faults and the identified components.

Abstract
A method and a device for maintenance of an elevator or escalator installation includes an interface for connection of a controller of the installation with a display and control unit for display of operating parameters or for input of control commands and data, and connection equipment for creating a data connection with a maintenance center. Data and parameters stored in the maintenance center can be transferred to the display and control unit by the data connection after an identification check. A fault log with a specification of operating faults and/or a specification of the replacement parts coming into question for rectification of the operating faults can be produced, which is transferred by the data connection from the display and control unit to the maintenance center, can be produced for example to cause ordering of missing replacement parts.

13. A device fox maintenance of an elevator or escalator installation, the installation including an interface for connection of a controller of the installation with a display and control unit for display of operating parameters and for input of control commands and data, and connection equipment for creating a data connection with a maintenance center, wherein data and parameters, which are stored in the maintenance center can be transferred to the display and control unit by the data connection and wherein operating faults of the installation are ascertainable by a test routine in dependence on a comparison between the operating parameters and the transferred data and parameters, comprising:
-
means in the display and control unit for obtaining the operating parameters from the installation through the interface, for obtaining data and parameters stored in the maintenance center through the data connection and for ascertaining operating faults of the installation by performing a test routine in dependence on a comparison between the on operating parameters and the transferred data and parameters; means in the display and control unit for associating at least one operating fault with at least one of the components and identifying the at least one component; and means in the display and control unit for producing a fault log with a specification of the at least one ascertained operating fault and the at least one identified component. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method of maintaining an elevator or escalator installation comprising the steps of:
-
a. connecting a portable display and control unit to an interface of the installation and logging on to the installation; b. identifying the installation to the unit; c. transferring operating parameters of the installation to the unit; d. requesting data and parameters of the installation from a maintenance center located remotely from the installation over a data connection between the unit and the center; e. checking access of the unit to the center; f. transferring to the unit from the center the data and parameters of the installation and transferring from the unit to the center the operating parameters; g. performing a test routine with the unit to ascertain operating faults of the installation in dependence on a comparison between operating parameters and the transferred data and parameters; h. identifying each of the components of the installation associated with the respective ascertained operating fault; i. producing a fault log with a specification of the ascertained operating faults and the identified components; and j. disconnecting the portable display and control unit from the installation.
