摘要： Disclosed is a ladder circuit diagram display system for an elevator, which automatically displays a ladder circuit diagram upon a failure on the elevator, to investigate a failure cause quickly and easily. The system has a maintenance computer (2) which reads, from an elevator control panel (1), trace data constituting a ladder circuit diagram, and displays a checklist on a screen based on the trace data. Upon selection of a coil on the screen, a circuit diagram file (2d) describing a ladder circuit diagram depiction method, and a contact count table file (2f) describing coil/contact point relationships, are used to depict the ladder circuit diagram of the selected coil with state of the contact point. If the contact point considered as the cause in the depicted ladder circuit diagram is not the actual cause, the computer (2) develops the contact point based on a selection, and depicts the ladder circuit diagram generating the contact point with the contact point state.
