Solutions to packaging machine failure

Release Time:


The solution to the problem of the electromagnet not closing is to first check whether there is an internal or external problem with the host; Secondly, check the safety tube of the electromagnet to see if there are any signs of power on the electromagnet, eliminate mechanical jamming, and test the internal power supply when everything is normal; The common causes of such faults in weighing and packaging machines are: sensor damage, voltage failure, incorrect circuit connection or interruption. The troubleshooting method is to detect the load signal of the sensor and wiring or the host, close and detect the bridge and amplification circuit or computer output display circuit, or remove the host, apply a reset signal through internal short circuit, determine whether the fault is inside the machine or from the switch, and then solve the problem.
