ELEVATOR HALL INDICATOR CONTROLLER AND ELEVATOR HALL INDICATOR CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide an elevator hall indicator controller and an elevator hall indicator control method capable of dispensing with a transformer, and suppressing a fluctuation in a power supply voltage of an elevator hall power supply device even if an operating state of an elevator hall indicator is switched in response to a control command.;SOLUTION: When a control command is received from an elevator control panel (100), a variation in a current value of a supplied current supplied from an elevator hall power supply device (200) before and after switchover of an operating state of an elevator hall indicator (320) is changed step by step in response to a magnitude of a difference between an operation current value of the elevator hall indicator (320) before switching over the operating state of the elevator hall indicator (320) and an operation current value of the elevator hall indicator (320) after switching over the operating state of the elevator hall indicator (320).;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
