The electromagnet does not pull in. Most of the reasons for this failure are the internal failure of the host, the blown out of the electromagnet coil, and the interruption of the circuit.
The solution is: first check whether there is a problem inside or outside the host; secondly, check the electromagnet fuse, check whether the electromagnet is energized, eliminate the mechanical jam, and check the internal power supply when everything is normal; in the weighing What is often encountered in packaging machines is that the reasons for this failure are: sensor damage, bridge supply voltage failure, line connection or interruption is wrong, the troubleshooting method is: check the load signal of the sensor and the connection or the host, and then check For bridges and amplifier circuits or computer output display circuits, sometimes the system stability is not good and the bag volume is unstable. To solve this problem, you can test whether the circuit is faulty.
