After clicking on the three corners of the contact screen, enter the offline form (note: different contact screens enter the offline form in different ways). Once in the offline format, click "INITIALIZE", and after clicking, keep clicking "SET-UP-I/O" and then "SET-UP-TOUCH-PANEL". FIND THE "USE-TOUCH-PANEL-AFTER-BACKLIGHT-BURNOUT" OPTION AND CLICK "YES" TO INDICATE THAT THE CONTACT FUNCTION IS BEING USED CONTINUOUSLY WHEN THERE IS A PROBLEM WITH THE BACKLIGHT OF THE CONTACT SCREEN.
When planning the industrial contact screen, in order to avoid misoperation, planners will add a backlight detection function, once the backlight burns out, the contact function will automatically become invalid. However, the function of the contact screen is actually normal at this moment, so after the above operations, the contact function can be temporarily enabled to allow the device to continue to use. However, as equipment protection personnel, from a rigorous point of view, it is necessary for us to replace the backlight of the contact screen as soon as possible to avoid equipment failure and even safety accidents caused by the accidental triggering of the contact screen.
The above is the main reason for the failure of the industrial contact screen, the damage caused by the basic normal use of a product is only two possibilities, one is the premature damage caused by the product's own planning problems, and the other is the internal damage of the product formed by too long time. If neither of the above two is the protection mechanism set up when the product leaves the factory, just like the backlight detection above. It is still hoped that each company will do a good job in the protection of the machine, so as to reduce the frequency of machine problems, extend the life of the machine, and improve the production power.
