The electromagnet does not pull in. Most of the causes of this failure are the internal failure of the host, the solenoid coil is blown, and the line is interrupted.
The solution is: first check whether there is a problem inside or outside the host; then check Electromagnet fuse tube, check whether the electromagnet shows signs of energization, eliminate mechanical jamming, and check the internal power supply when everything is normal; often encountered in weighing and packaging machines is the cause of this failure: sensor damage, The supply bridge voltage is faulty, and the line connection or interruption is incorrect.
The troubleshooting method is: detect the load signal of the sensor and the connection or the host, and recently detect the supply bridge and the amplification circuit or the computer output display circuit. Sometimes the system stability also occurs. It is not good to cause unstable bag quantity. To solve this problem, you can test whether the line is faulty.
