|
It is essential to observe the following aspects when cleaning the control panel:
- Keep to the boundary conditions of protection rating IP65.
- Never use compressed air to clean the panel.
- Maintain an ambient temperature range of 0 °C to 55 °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 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 Control Tool does not start automatically when the device starts up. Proceed as follows to activate the "Cleaning Mode" of the Beckhoff Control Tool:
- 1. Go to 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.
- 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 panel PC 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.).
