Therefore, Q3654 maintains the OFF state. In the short or open state: The voltage appears at D3664 anode in the short state and appears at D3665 anode in the open state. Q3654 turns ON and XPROTECT becomes low (Active). u163 XW-HTD640 http://www.xiaoyu163.com... - Page 60 Note: When the protection function is activated, as the POWER LED is turned off and the fan does not rotate, it appears as if the power was just shut off. When diagnosing, you can differentiate protection status from power-off status by checking if +8 V power to the FET in the AMP module is on or not. u163 XW-HTD640 http://www.xiaoyu163.com...
