PROBLEM TO BE SOLVED: To require no new wiring, by connecting in series a contact of a parking switch to a lamp and a connection cable of a lamp lighting circuit, and by making a normally-closed contact of a contact of the parking switch. SOLUTION: A normally-closed contact PK, SWb is connected in series to a call responding lamp HB1L at an elevator spot in a spot call responding lamp circuit. A relay XLHBL1 for detecting normal condition of the spot call responding lamp circuit is connected in parallel to an output signal ZHB1 for lighting the call responding lamp at the spot. An normally-closed contact XHB1 a of a relay for detecting a call button operation and an normally-closed contact XHB1b of a relay for detecting normal condition of the spot call responding lamp circuit is connected in series to a parking order detecting relay XPK. When a parking switch is operated, the normally-closed contact PK, SWb is opened, and the relay XHBL1 for detecting normal condition of the spot call responding lamp circuit is de-energized. |
