Abstract (en)
A testing method and a testing device (41) for testing an integrity of an elevator signal transmission line (39) including a CAN bus communication cable in an elevator (1) and/or an electric series interconnection of several safety relevant components (16) in a safety chain (31) in an elevator (1) are described. The testing device (41) comprises a time domain reflectometer (43), a connection device (45) and an outputting device (47). The testing device (41) is configured for executing the testing method comprising:- using the time-domain reflectometer (43) connected to the elevator signal transmission line (39) for transmitting an electric pulse generated by the time-domain reflectometer (43) through the elevator signal transmission line (39);- detecting reflections of the electric pulse;- determining an information about a location of a fault in the elevator signal transmission line (39) based on the detected reflections of the electric pulse; and- outputting the information about the determined location of the fault.With the proposed approach, information about an absolute position of a fault within the elevator signal transmission line (39) may be automatically acquired even in high-rise elevators (1) comprising a multiplicity of safety relevant components (16). The information may be output such that for example a technician may easily find and repair the detected fault.
