Source: InternetPublisher:张三叔 Keywords: Power supply protection Updated: 2021/06/03
Water enters the motor and submerges the probe A. The water connects A to the casing. The relay K is closed, the normally closed contact is disconnected, KM loses power and is released, and the motor M stops. At the same time, HA sounds an alarm. Inform the staff to eliminate the water source, cut off the power switch, and dry the motor.
