Cleaning the front screen
You can clean the front screen of the control panel during operation. In order to avoid inadvertent touch entries when doing this, you must first set the device to "Cleaning Mode" with the help of the Beckhoff Control Tool.
The Beckhoff Control Tool does not start automatically when the connected PC starts up. Proceed as follows to activate the "Cleaning Mode" of the Beckhoff Control Tool:
- 1. Click the Beckhoff Control Tool to start it.
- When the tool is started, a small sun symbol appears in the taskbar.
- 2. Right-click the sun symbol. Touch the sun when operating via the touch screen.
- 3. Select the "Cleaning Mode" (see Fig. 14).
- "Cleaning Mode" is activated. You can now clean the front panel.
You can set the duration for which the panel should remain in "Cleaning Mode". The period can be set between 5 and 120 seconds. Right-click the sun symbol again and click "Options". Now select the appropriate period (see fig. 15).
