5.3 Operating a device with 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
).
You can find additional information on connecting the earth conductor in the section
"Connecting the Equipotential Bonding Circuit (Page 38)".
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.
WARNING
Danger of malfunction due to improper execution of gestures on the touch screen
If gestures are executed incorrectly on the touch screen with multi-touch function, these
gestures may not be recognized or could be recognized incorrectly. The entries made are
then not implemented by the device or are implemented incorrectly or in an unintended
manner.
Incorrect execution of multi-touch functions can lead to errors in the operation of the plant
and thus to physical injury.
Note the following when operating the touch screen with multi-touch function:
•
The touch screen reacts to contact on its surface, not to pressure.
• When using a touch pen: Operate the touch screen only with a touch pen for capacitive
touch.
•
Avoid unintended multiple touches, for example, with your knuckles.
Before you start to operate the device, make sure you are familiar with the multi-touch
functions of the Windows operating system, as well as with the application to be used and
its functions. Ensure that the gestures which the user executes on the multi-touch display
are recognized by the application. It is possible that certain gestures need to be trained
beforehand.
