5.2
Operating a device with resistive single-touch screen
When you touch an object on the single-touch screen, the corresponding function is
performed.
Note
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.
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
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 might 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.
WARNING
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 earth (Page 49)."
