Notes on the touch panel

Clean screen
Only applies to HMI devices with a touchscreen:
The HMI device touchscreen can be cleaned when switched on and when operating
normally if touchscreen input has been suppressed by means of an appropriately configured
operating element (Clean Screen). After the Clean Screen function has been activated, all
input via the touchscreen operating elements is deactivated for a defined period of time. The
time remaining until the end of operating suppression is indicated by a progress bar.
Notice
Suppressing operating elements
Only clean the screen during operation when Clean Screen is activated. Note the end of
operating suppression by the Clean Screen.
Otherwise, incorrect operations may be initiated.
Protective foil
A protective foil is available for the touchscreens on HMI devices. The necessary ordering
information is provided in the Siemens Catalog ST 80. The protective foil is not part of the
material supplied with the HMI device.
The self-adhesive foil prevents the screen from being scratched and soiled. In addition, the
matte surface of the foil reduces reflections in poor lighting conditions.
The protective foil can be removed as necessary without leaving any adhesive residue on
the screen.
Caution
Remove protective foil
Never use sharp or pointed tools, such as a knife, to remove the protective foil. This may
damage the touchscreen.
