Industrial touch screen is a resistive screen, better than capacitive screen anti-interference, but generally if no response, most of the outer touch glass (generally called the touch panel) is bad, buy a domestic compatible, direct replacement is good, of course, does not exclude the following problems:
1. touch screen and PLC are generally used together, through the communication cable to exchange data, in the case of communication cable breakage, communication port damage, or PLC operation is not normal, etc., the industrial touch screen will be in a pseudo "dead" condition, if through the back of the dial switch can enter the screen backstage menu interface, are generally this Problems.
2. Touch screen control card failure;
3. The screen appears to drift, conditions allow, you can consider using the usual hair blowing hot air blowing screen, open to the middle of the gear is good, in the state of the shutdown uniformly blow down the screen, feel the screen is hot on the good, reboot generally available.
4. Magnetic fields and other interference caused by, then away from the magnetic field or demagnetization can be dealt with, if it is the impact of static electricity, sweat and oil, the human body in specific circumstances may also be static electricity, sweat and oil, should be actively cleaned to protect. If it is dead or fake dead, turn off the screen or restart the machine, generally can be solved;
5. caused by excessive touch deviation, general industrial touch screen has a calibration method, such as some of the four corners at the same time in accordance with the operation to achieve.
Industrial touch screen touch function fails to deal with what are the methods
With the improvement of science and technology, the stability of industrial products is getting stronger and stronger. As a high-tech product, industrial touch screen has been fully verified in practice. Therefore, when the touch function fails in the touch screen, first try to enter the offline mode and verify whether the failure point of the touch screen is burned out. If the cause of failure is burned out backlight, then we can temporarily restore the touch function of the touch screen through the following steps (the following is an example of Proface GP series touch screen).
1. Click the three corners of the industrial touch screen to enter offline mode (Note: Different touch screens enter offline mode in different ways).
2. After entering offline mode, click "Initialize".
3. After clicking, "SET UP I/O" will appear.
4. When "Set Up Touch Panel" appears, click "Set Up Touch Panel".
5. When the "use the touch panel after the backlight is exhausted" option appears, click "Yes" to indicate that when the touch screen backlight failure, the touch function will continue to use.
When designing industrial touch panels, designers will add backlight detection to prevent misuse. Once the backlight burns out, the touch function will be automatically disabled. However, at this point, the touch screen function is actually normal, so by doing the above, the touch function can be temporarily enabled to allow the device to continue to be used. However, as equipment maintenance personnel, from a rigorous point of view, we must replace the backlight of the touch screen as soon as possible to prevent equipment failure or even safety accidents caused by touch screen false triggering.
