APPLICATION NOTES

Auto Restart Protection

When the fan motor is locked by an external force, the device will temporarily turn oﬀ electrical power to the motor and

restart automatically when the locked rotor condition is released.

Polarity Protection

Able to withstand 10 minutes of reverse polarity connection between the positive and negative wires without causing

damage.

Tachometer Signal (Yellow Wire)

The tachometer signal is for detecting the rotational speed of the fan motor. The output will be a square wave when fan is

operating and VFG or VCE depending on the locked rotor position when fan motor is locked (See Figures 1~2 below).
