Operating the 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
Personal injury or property damage due to no ground connection
An inadequate connection to ground or the lack of one may 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 an earth conductor.
•
The ground conductor of the device must be connected directly to ground with low impedance (short connection,
minimum conductor cross-section 4 mm
2
).
You can find additional information on connecting the grounding conductor in the section "Connecting the power supply
(Page 23)".
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.
•
Only carry out an operator action when a plant screen is shown on the device display.
•
When you disconnect the DisplayPort/DVI connection, then also disconnect the USB connection of the USB cable Type B
connector - Type A connector.
•
Make sure that the touch screen is kept free of dirt.
•
Switch off the device for cleaning and maintenance.
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
Do not touch the capacitive multi-touch screen during startup
The device automatically calibrates the capacitive multi-touch screen during startup. The touch screen is locked during
calibration.
Do
not
touch the touch screen during startup. Make sure that you do not rest on the touch screen with the palm of your hand
during startup.
Make sure that there are
no
conductive liquids on the touch screen during startup.
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.
