Aluminum frame and casing in appealing design, powder-coated in "steel"-gray color, provides protection and gives a timeless look. The front enclosure is IP66 classified, which means that it is waterproof even when exposed to high pressure washing. The 16 function keys can be used for controlling, with an explanatory text in the display or on a text strip, and the 16 LEDs for status indication. The operator panel is configured with the user-friendly software tool Information Designer.
