WARNING
Personal injury or property damage due to maloperation
Incorrect operation of touch devices cannot be ruled out. 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.
•
Only carry out an operator action if a plant screen is shown on the HMI device screen.
•
Switch off the HMI device for cleaning and maintenance.
NOTICE
Damage to the touch screen
The following operation significantly reduces the service life of the touch screen and can
lead to total failure:
•
Touching with pointed or sharp objects
•
Shock contact with hard objects.
Only touch the touch screen with a finger or a touch pen.
WARNING
Danger of malfunctions due to incorrect 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 touch 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.
Observe when operating the capacitive multi-touch screen:
•
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 using the HMI device, familiarize yourself with the supported multi-touch functions of
the operating system and the applications. Ensure that the gestures which the user
executes on the multi-touch screen are recognized by the application. It is possible that
certain gestures need to be trained beforehand.
