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.
• Make sure that the touch screen is kept free of dirt.
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.
Notes on operation
Note when operating the multi-touch screen:
• Surface contact with a diameter of about 5 to 20 mm is required for an operator action to be detected.
• An operation with gloves with a material thickness of <2 mm is detected in most cases. However, check the usefulness of
the gloves you are using.
• To avoid incorrect operation, certain inputs are ignored and blocked from further entry:
–
Simultaneous operation with more than 5 fingers.
–
Surface contact with a diameter of > 3 cm, for example, resting the palm of the hand on the touch screen.
–
As soon as the touch screen is no longer touched, input is possible again.
Functions of the multi-touch screen
General functions
• Detection of up to 5 finger touches at a time.
• Detection of gestures that are supported by the operating system or the software installed on the device.
Note
Multi-touch operation can provide advanced features or pose limitations depending on the operating system and the
software installed on the device. Read the corresponding documentation.
• You do not need to calibrate the touch screen. Some operating systems do offer touch calibration. However, this
calibration does not result in an improvement of the accuracy.
Security functions in an industrial environment
The touch screen is locked for security reasons when following happens:
• There is a conductive liquid on the touch screen with ground contact via the enclosure or the operator, for example.
• Electromagnetic interference is present that exceeds the specification according to EN 61000-4-2.
Once the interference is over, the touch screen is no longer locked.
