The task of screening plants is to separate overburden of different grain sizes in opencast mining and to separate and recycle materials on construction sites. Different types of materials have to be sorted and environmental pollution minimized, especially on construction sites. The safety of all people working on the construction site is the top priority. Graf-Syteco has developed an HMI with functional safety in category 2 for the operation of the conveyor belts and screening systems, which achieves a performance level of PL d.

The maintenance of the road infrastructure is a key prerequisite for maintaining the supply of goods of all kinds to the population and individual traffic. In order to keep costs low, the top layer of damaged road surfaces is removed with a milling machine and filled with a new asphalt surface. With the HMI from Graf-Syteco, the milling depth on such road milling machines is precisely adjusted and relevant parameters for the milling process are displayed on the screen.

One of the most common methods of supplying concrete on construction sites is to simply pump it a few meters from the transporting truck to the processing site. There are various control concepts for these pumps. An established concept in the industry comes from Graf-Syteco and is based on an integrated operating and control unit that both displays the machine parameters and controls the entire process in the C program. Alternative concepts of a separate mobile control system are equipped with pure Graf-Syteco display devices for user input.

Despite their very low mileage, fire engines generally have an extremely long life cycle compared to transport trucks. This requires parallel long-term availability of electronic components such as I/O modules and operating and control units.
Graf-Syteco guarantees through experience in the design of electronics and through modular concepts in hardware and software.

To avoid accidents and collisions with colleagues or passers-by, drivers of refuse collection vehicles depend on the reliable functioning of mobile controls, mobile I/Os, operating and display devices and assistance systems. The Graf-Syteco HMIs in the driver's cab display camera images, superimposed parameters from sensors as well as messages and warnings. The driver can put the machine into a safe state at any time using an emergency stop button directly on the HMI.
