date 01/20/2022 │ page 7 of 8CUI Devices │ SERIES: CFM-40BG │ DESCRIPTION: DC AXIAL FAN cuidevices.com 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. 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). Figure 1: Tachometer Output Circuit Figure 2: Tachometer Output Waveform Polarity Protection Able to withstand 10 minutes of reverse polarity connection between the positive and negative wires without causing damage. Figure 3: Soft Start Soft Start When the fan power is on, the current will increase slowly (~15 seconds) until the fan reaches the rated speed. ~15 s I (A) t Rated Current Output Type: Open Collector Vs: (VFG) 5 V fan: 3.3~5 V All others: 3.3~15 V Ic≤5 mA R≥Vs/Ic VCE(sat)≤0.5 V
