After the enterprise purchased the automatic dispensing machine and began to put into production, the operators may often encounter the machine can not be reset when operating the automatic dispensing machine. But they don't know how to repair it, which not only affects the work efficiency, but also affects the evaluation of the machine by the enterprise. Under normal circumstances, the dispensing machine will automatically restore to the set state when the system is turned on for subsequent operations. But sometimes the machine is not reset after the system is turned on, that means the system has a problem and needs to be repaired.

The daily maintenance of the dispensing machine directly affects its service life. If there is no maintenance for a long time, resulting in the malfunction of the dispensing machine, it will also affect the reset of the dispensing machine. So the daily maintenance of the dispensing machine has a great impact on the service life of the dispensing machine, as well as the smoothness of the daily use. 

In the event that the machine cannot be reset, first of all, it is necessary to check whether the emergency stop button of the system has been pressed. After the button has been pressed, the configuration file needs to be checked. It is recommended to perform a re-upgrade and check if the compiler used is the correct version to prevent a mismatch between the compiler and the configuration file. The hardware connections also need to be checked, as it is also possible that the machine cannot be reset when there is a problem with a driver, switch or wire jumper.
