Basic Panels 2nd Generation 
Operating Instructions, 10/2016, A5E33293231-AB

All Basic Panels 2nd Generation come equipped with a touch screen and function keys. You 
use the touch screen to operate the Start Center or the project running on your HMI device. 
You use the function keys to trigger the associated configured functions within a project.  
 
A project can contain certain operations that require in-depth knowledge about the specific 
system on the part of the operator. 
Ensure that only trained professional personnel operate the system. 
Operating the touch screen 
 
Damage to the touch screen 
Pointed or sharp objects, abrupt contact, and continuous gesture operation can significantly 
reduce the life of the touch screen and possibly lead to total failure of the touch screen. 
•  Do not touch the touch screen with pointed or sharp objects. 
•  Avoid contacting the touch screen abruptly with hard objects. 
•  Avoid continuous operation of the touch screen with gestures. 
Triggering unintended actions 
Touching several operating elements at the same time can trigger unintended actions. 
Touch only one operating element on the screen at a time. 
Operating elements are touch-sensitive symbols on the screen of the HMI device. 
They are basically operated in the same way as mechanical keys. You activate operating 
elements by touching them with your finger. 
 
Note 
The HMI device returns a visual feedback as soon as it detects that an operating element 
has been touched.
 
The visual feedback is independent of any communication with the c
ontroller. The visual 
feedback signal therefore does not indicate whether or not the relevant action is actually 
executed.
