Abstract:
PROBLEM TO BE SOLVED: To provide a passenger conveyor equipped with a control device that can notice an alarm when the passenger conveyor is operated in maintenance work without fail and allows the passenger conveyor to be operated only when operated by a proper operation procedure.SOLUTION: The passenger conveyor notifies an alarm by ON-operation of an alarm switch, and is allowed to be operated only when ON-operation of an ascend switch or a descend switch is performed following the ON-operation of the alarm switch. This allows the passenger conveyor to be operated only when the ON-operation of the ascend switch or the descend switch is performed following the ON-operation of the alarm switch, so that the alarm can be previously notified to alert attention and the passenger conveyor can be operated unless the ascend switch or the descend switch is in an ON failure, leading to improvement in safety for maintenance work.
