Abstract
The invention refers to a method for accessing an passenger transportation device control means comprising several separated printed circuit boards (PCB), whereby each of these PCBs comprises a unique identifier (ID), and in which method the passenger transportation device control means comprise a matching table which is used by the passenger transportation device control means to perform a matching test to check the identifier of at least two of the PCBs and to put the passenger transportation device control means into normal operation only if their IDs match the IDs of the matching table. A service technician connects via a key to the passenger transportation device control means, which key enables the service technician to set the passenger transportation device control means into a fault finding mode, in which fault finding mode the passenger transportation device control means are initiated to skip the matching test before getting into operation, whereby the fault finding mode is terminated at the latest when the service technician terminates the key-based connection with the passenger transportation device control means.
