Faulty touch screen function

Cleaning the front screen without cleaning the edge of the glass screen can lead to faulty touch screen functions due to liquid residue.

Always clean the front screen including the edge of the glass pane to avoid liquid residue.

It is essential to observe the following points when cleaning the PC:

Keep to the boundary conditions of protection rating IP65.
Never use compressed air to clean the PC.
Maintain an ambient temperature range of 0 °C to 45 °C.

Cleaning agents

In order to avoid damage to the front of the panel PC during cleaning, you must use suitable cleaning agents. Examples include:

benzine
spirit
glass cleaner

Avoid the following cleaning agents:

detergents with scouring or abrasive components
metal cleaning objects such as razor blades or steel spatulas
steam jet cleaner or very hot water
cold water with a heated device
high water pressure, e.g. high-pressure cleaner

Cleaning the front screen

You can clean the front screen of the device 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 Display Control Tool. Also make sure that you not only clean the display area, but also the edge of the glass pane. Impurities in the edge area or liquids that do not run down the glass pane as drops but as a long short-circuit bridge create an electrically conductive connection between the touch screen area and the metal housing of the device. This unintentionally triggers a touch event at the edge of the touch screen, which can lead to incorrect operation.

The Beckhoff Display Control Tool does not start automatically when the device starts up. Proceed as follows to activate the "Cleaning Mode" of the tool:

1. Click the Beckhoff Display Control Tool icon to start it.

When the tool is started, a small sun symbol appears in the taskbar.

2. Right-click the sun symbol.

3. Select the "Cleaning Mode" (see Fig.).

"Cleaning Mode" is activated. You can now clean the front panel.

You can set the duration for which the device 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 duration (see Fig.).
