Keyence VT3-Q5HG Front Overlay HMI Touch Screen Repair

Measures for improving noise resistance
Do not mount the VT3-Q5HG Touch Panel Front Overlay VT3 inside industrial control panels in which high-voltage devices are also located.
Mount the VT3 as far away as possible from power lines.
Mount the VT3-Q5HG Protective Film Touchscreen VT3 as far away as possible when it must be mounted next to devices (e.g.solenoids, choppers)that generate strong magnetic and electrical fields.
Do not include the VT3's I/O leads in the same ducts as power lines and high-voltage lines. Wire the l/O leads in separate ducts. Noise from power lines and high-voltage lines may cause malfunction on the VT3.
Allow as much space as possible between the VT3 and surrounding structures and other components to improve maintainability, operability and ventilation.
On VT3-Q5HG HMI Touch Screen Front Overlay VT3 models that are provided with a protective earth terminal and shielded lead, provide a D-type grounding (maximum resistance of 100 Ohms).
