The electromagnet does not pull in. Most of the reasons for this failure are the internal failure of the host, the solenoid coil is blown, the line is interrupted, etc. The solution is: the first check whether the host has a problem inside or outside;
second, check the Electromagnet fuse, check whether the electromagnet is energized, eliminate mechanical jams, and check the internal power supply when everything is normal; what is often encountered in weighing and packaging machines is that the cause of this failure is: sensor damage, If the bridge voltage is faulty, the line connection or interruption is wrong, the troubleshooting method is: detecting the load signal of the sensor and the connection or the host, and detecting the bridge and the amplifying circuit or the computer output display circuit when it is close, sometimes the system stability may occur If it is not good, the bag quantity is unstable. To solve this problem, you can test whether the line is faulty.
