Kind Code:

Abstract:
The purpose of the present invention is to renovate an elevator without inconveniencing the users of the elevator. When replacing control panels with new control panels (106'-1 to 106'-3), a signal converter (400-1 to 400-3) that converts a signal output from a component (700-1 to 700-3) into a different signal having the same meaning as the signal and understandable to a new control panel (106'-1 to 106'-3) is connected between each new control panel (106'-1 to 106'-3) and the corresponding components (700-1 to 700-3), after which at least one of the components (700-1 to 700-3) is replaced with a new component (700'-1, 700'-2) that outputs a signal which is understandable to the new control panel (106'-1 to 106'-3). By this replacement work method, the replacement of components (700-1 to 700-3) with new components (700'-1, 700'-2) can be spread out. Furthermore, the signal converters (400-1 to 400-3) function as group management devices for managing an elevator group.
