Operating the capacitive multi-touch screen
You operate the multi-touch screen with one or multiple fingers. You can also operate it
using gestures with up to five fingers at a time.
WARNING
Personal injury or property damage due to no earth connection
An inadequate earth connection or the lack of one may 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 an earth conductor.
•
The earth conductor from the device must be connected directly to earth with low
impedance (short connection, minimum cross-section 2.5 mm
2
).
WARNING
Personal injury or property damage due to maloperation
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.
