2.6 Notes on the touch screen
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.
Damage to the touch screen
Impact with hard objects as well as touching the touch screen with pointed or sharp objects
can damage it and lead to a significant reduction in service life or even total failure of the
touch screen.
Never touch the touch screen with pointed or sharp objects. Only touch the touch screen
with your fingers, a touch stylus or an approved touch glove.
Avoiding malfunctions
Personal injury or property damage due to no protective conductor
An inadequate protective conductor or the lack of one might cause malfunction of the
capacitive touch screen. Functions may not work properly. This can result in personal injury
or property damage.
• Always connect the device to a protective conductor.
• Additional information on connecting the protective conductor can be found in the
section "Connecting the protective conductor (Page 42)."
