Personal injury or property damage due to incorrect operation
Incorrect operation of devices with a touch screen can occur. This can result in personal
injury or property damage.
Take the following precautions:
• Configure the plant so that safety-related functions are not operated with the touch
screen.
• Switch off the device for cleaning and maintenance.
• Make sure that the touch screen is kept free of dirt.
For resistive single touch screen:
• Always touch only a single point on the touch screen.
• Calibrate the touch screen regularly, at the latest when the touch screen becomes
inaccurate or does not respond despite repeated touches.
Operating a device with resistive single touch screen

Appearance of blisters under extreme ambient conditions
Under extreme environmental conditions such as high atmospheric humidity and
temperature, bubbles can form on the touch surface in rare cases. This only
affects the
appearance and does not represent any functional restriction.
