Summary:PURPOSE:To measure the vibration and grounding level of a car and adjust the control constant of a microcomputer on the spot by connecting a maintenance adjusting tool to signal input/output circuits of a car operation switch and a car position indicator. CONSTITUTION:A maintenance adjusting tool is connected to a car operation panel for the adjustment of an elevator, the input data via the operation of the tool are converted into communication data by a signal transmission control circuit 20 and transmitted to a call signal control circuit 30 via the call button of the car operation panel and an input/output buffer 10 for a response lamp. The call signal control circuit 30 interrupts the normal transmission of the operation signal of the car operation panel to an operation control circuit 40 and gives the communication data converted by the signal transmission control circuit 20 to a maintenance inspection control circuit 50 instead. The control data of the operation control circuit 40 and a motor control circuit 60 can be read or written, and the riding comfortableness of the elevator and the constant of the grounding level can be adjusted.
