Description

Fan drive monitoring system {Monitoring system for fan operating}

The present application relates to a fan drive monitoring system, and more particularly, to a fan drive monitoring system that can easily check whether the fan is operating normally through a plurality of LEDs provided for each function.

In particular, the machine or equipment used in the semiconductor process is sensitive to the change in the operating conditions, causing malfunction or down occurs. Since the heat generated from the parts itself has a fatal effect on the lifespan of the parts, in order to prevent overheating of the device and to operate a stable device, a fan is installed for the heat dissipation of the main parts or parts to generate heat. do.

Typically, the fan rotates the blades by driving with a motor to protect the product or device from heat throughout the industry, and uses the convection generated at this time to cool down the heat generated by a given heating element in the product or device. Do this.

If the fan is operated abnormally, the internal temperature rises and the life of the parts is reduced, malfunctioning or the equipment is down in severe cases, and severe overheating may cause ignition, causing serious damage to the machine or equipment.
