Abstract
PURPOSE:To make maintenance work high-efficiency and make the control system safe by providing a function, by which the maintenance unit for a control unit is connected and disconnected, in the control unit controlled by an operating control computer. CONSTITUTION:Before elevator control unit 20 including control computer 3 and maintenance unit 21 are connected electrically through 7, 8 and 9 by signal lines, it is decided whether they have been connected or not. If it is decided that they are not connected, a function to make the receiving function of control data for maintenance in computer 3 ineffective is provided in computer 3. Further, it is decided whether they have been connected electrically or not; and if it is decided that they have been connected, a function to make the transmission and receiving function of control data for maintenance between computer 3 and unit 21 effective is provided. Thus, maintenance work can be made high-efficiency, and the control system can be made safe.
