Structure and method for failure diagnosis of pcb board for article transport elevator

A method for failure diagnosis of a PCB board for an article transport elevator, characterized in that in the PCB board for an article transport elevator which allows a transport car loaded with articles to ascend/descend and arrive to a locker position selected from among lockers provided on each layer of a multi-layer structure, and allows the articles to be supplied by the door opening/closing operation of the locker where the transport car has arrived, respective circuit units that connect a power supply unit of an article transport elevator, a seesaw switch unit of each layer, a car arrival limit unit, a car operation condition unit, and a car operation state unit through a connector;

• and lamps that turn on in accordance with whether the power supply unit, the seesaw switch unit of each layer, the car arrival limit unit, the car operation condition unit, and the car operation state unit operate normally or not, are installed so as to be connected to each other,
• whereby an operator collectively diagnoses the presence or absence of a failure of the power supply unit, the seesaw switch unit of each layer, the car arrival limit unit, the car operation condition unit, and the car operation state unit in accordance with the presence or absence of turn-on/off operation of the lamps of the PCB board.
