MOTOR-DRIVEN LIGHTING WINDOW DEVICE HAVING RAIN SENSOR

摘要

PURPOSE:To ensure construction of a motor-driven lighting window device by incorporating a resistance equipped with an offset function to transmit a certain frequency into a lighting window control unit which closes the lighting window when detecting rain by means of a rain sensor, an making it possible to find disconnection of the rain sensor while checking operation of the lighting window. CONSTITUTION:A frequency offset resistance R2 is incorporated into a control unit 2 which drives a motor 9 when recognizing rainfall from lowering of the output frequency of a rain sensor 1 and which cannot open a lighting window by control of a remote controller 10 when operated in response to the output from the rain sensor 1. Even when a connector 3 is disconnected a certain frequency is transmitted from the offset frequency R2 and rain conditions are produced so that when operation of the lighting window is checked the remote controller is not operated. Disconnection of the rain sensor 1 can thus be prevented.
