2.7 Important notes on touch screen
Functions of the capacitive multi-touch screen
General functions
• Detection of up to 5 finger touches at a time.
• Recognition of the gestures supported by the operating system and the runtime software.
• You do not need to calibrate the capacitive multi-touch screen.
Security functions in an industrial environment
The capacitive multi-touch screen is locked for security reasons when the following
disturbances occur:
• There is a conductive liquid on the touch screen with ground contact via the enclosure or
the operator, for example.
• An electromagnetic disturbance that exceeds the specification in the technical data of the
device exerts an influence, see section "Electromagnetic compatibility (Page 49)".
Once the interference is over, the capacitive multi-touch screen is no longer locked.
