6.3 Deactivate Screen
Purpose
Soiling the TP 070 touch screen cannot be avoided during normal operation.
Therefore, the TP 070 should be cleaned at regular intervals. Deactivate the
screen prior to cleaning to prevent triggering a function unintentionally.
Conditions for deactivating the screen
In order to deactivate the screen on the operating unit, the function
Clean Screen
must have been assigned to a button in the project.
After touching the relevant button, the screen is cleared and a bar graph appears.
The screen is then deactivated for the time
Deactivation time
defined in the
configuration (default setting: 30 seconds). The TP 070 can then be cleaned
without any functions being triggered inadvertently. The way to clean the TP 070 is
described in chapter 10.
The bar graph on the screen indicates the time remaining until the touch panel is
reactivated.
