The electromagnet does not pull in. The cause of this failure is mostly the internal failure of the host, the electromagnet coil blown, the line interruption and other reasons. The solution is: first check whether there is a problem inside or outside the host; secondly check Electromagnet safety tube, check whether the electromagnet has signs of power, eliminate mechanical jamming, and check the internal power supply when everything is normal; the cause of this failure is often encountered in weighing packaging machines: the sensor is damaged, The bridge supply voltage fault, the line connection or interruption is wrong, the method of elimination is: detect the load signal of the sensor and the connection or the host, and closely detect the supply bridge and the amplifier circuit or the computer output display circuit, and sometimes the system stability will occur If it is not good, it will cause unstable bagging volume. To solve this problem, you can test whether the circuit is faulty.
