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.
•
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 lead to improved accuracy.
Security functions in an industrial environment
The touch screen is locked for security reasons when the 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.
Additional information
A "touch pen system", which is suitable for both single-touch and multi-touch screens, is available on the Internet
(http://www.siemens.com/automation/mall) (6AV2181-8AV20-0AX0).
Support of multi-touch devices
The "Panel Drivers and Tools" software version that is pre-installed on this multi-touch device does not support all functions
described in the operating instructions.
The following function is not supported:
● Changing from multi-touch to single-touch mode on multi-touch devices.
To use these functions, install the revised "Panel Drivers and Tools" software, which is stored on the USB stick supplied with
the device, in the directory "DocuAndDrivers\Drivers\PDT\PDT_02".
Note
Existing drivers
You must uninstall the existing drivers before installing new drivers.
