PURPOSE:To easily judge a mischievous call and reduce the labor of a manager by indicating the run of a cage by two cage buttons operated in a managing room. CONSTITUTION:It is assumed that a passenger mischievously pushes a call button and leaves away when a cage is landed on a ground floor. Then, the manager pushes cage call buttons 1BXa, 2BXa in the control board K of a managing room, whereby a relay 2C is energized, an indicator lamp 2L in the cage, and also an indicator lamp 2LX in the managing room are lighted. Even if the button 1bxa is pushed, a relay 1c is not energized, and also an indicator lamp 1LX is not lighted as a contact 1Pb is opened. As the cage is normal, it is started from the ground floor toward the second floor and landed thereon. Consequently, the contact 2Pb is opened, the relay 2c and the indicator lamp 2LX are extinguished to show the normal operation of the cage, and the call button IBa is found to be mischievously pushed. |
