<p>PURPOSE: A fan drive monitoring system is provided to easily check a normal and abnormal operation of a fan through LED and prevent a PCB malfunction in a flex controller. CONSTITUTION: A body(110) is installed in a shroud(102). Multiple LEDs(120) are installed in the front side of the body. A power LED is installed in the rear side of the body and displays a power supply state. A state LED is installed in the rear side of the body and displays an operation state of a fan. A sensor(130) senses the rotation state of the fan. A controller(140) receives a sensing signal which is generated in the sensor, checks the operation state of the fan(101), and generates and outputs a display control signal which determines the on/off state of multiple LEDs. A power supply unit(150) supplies power to multiple LEDs, the power LED, the state LED, the sensor, and the controller.</p> |
