PROBLEM TO BE SOLVED: To improve the efficiency of the inspection work of floor selector buttons of an elevator. SOLUTION: When an inspection switch 8 is operated, an inspection relay 9 is energized and contact points 9c and 9d are opened. When a floor selector button 5 or 6, for example, is pressed under that condition, a floor selection registration relay 10 or 11 is energized only while the floor selector button 5 or 6 is being pressed and the floor selection is not registered. Accordingly, a floor selection registration light 16 or 17 is lighted only while the floor selector button 5 or 6 is being pressed. As a result, the inspection for disconnection of the floor selection registration light 16 or 17, etc., covering one floor is possible. COPYRIGHT: (C)2003,JPO
