Overheating Protection Function

Protection Functions

If the fan blades are restricted , an overcurrent occurs and leads to a rise in the fan coil temperature . This can result in reduced performance , damage , or a fire . To prevent this from occurring , Sanyo Denki ‘ s fans incorporate an overheating protection function . Refer to the catalog for the types of protection functions .

AC fan overheating protection functions

*lmpedance protection

This system is used for shading coil – type fans . When the blades are restricted , the current is reduced by the impedance of the coil itself to prevent a temperature rise in the coil . However , if the applied voltage exceeds the specification range , an overcurrent can occur and result in overheating , and so care needs to be taken .

*Thermal protection

This system is used for condenser phase – type fans . A temperature sensor is incorporated in the coil so that if the temperature exceeds the specification temperature , the current is cut off to prevent overheating of the coil .

Operating precautions

Storage temperature

There is no performance problem when the system is used at between -30℃ and +70℃. There is a possibility that same problem of lubricant and insulation inside motor might occur by condensing due to rapid surrounding temperature change . Therefore , please take care of non – condensing using desiccant or something during fan is in storage.

Tightening Torque

This shows the recommended values for the tightening torque when installing the fans . If the tightening torque is higher than the recommended values , the fan can be deformed or damaged . Use care when tightening . Recommended screw torques
Fans :0.44N· m (4.5kgf· cm ) MAX .( with M3 screws )        Fans :0.78N· m (8kgf· cm ) MAX .( with M4 screws )

Handling precautions

The fan motor is equipped with a precision ball bearing . Therefore , please handle the motors carefully in order not to shock the bearings .

Installation

There are no limitations on the installation direction . Fans have symbols on the fan indicating the airflow direction and blade rotation direction . When installing , use these symbols to check the airflow direction .
