The camera is mounted on a slide, which crosses access to the understage area at high speed downstage. Previously, flashing lights had warned of the approaching slide camera. The idea was to optimise this concept, to increase the safety of the stage technicians and exclude manipulation. Today, the danger zone is secured by Pilz’s Type 3 light curtains PSENopt II with hand resolution. Should anyone reach or run into the first pair of light curtains while the camera is moving, the camera slide is stopped immediately. Only once the person has passed through the second light curtain is the zone reset automatically and the slide camera enabled. With this adaptation, the Ehrlich Brothers can happily concentrate on the dramatic composition of their show – for the perfect illusion. http://www.pilz.com

In addition to using PSS 4000, Arcelor Mittal also commissioned Pilz to completely overhaul the plant. One challenge in this modernisation process was the frequent shutting down of the start-up burners that ignite the main burners, which repeatedly led to extended outages. The existing burner control module and flame monitoring via UV cells were not an optimum solution: as soon as one of the cells was defective, the entire plant was often stopped for at least 40 minutes, as the analysis options when searching for the defective UV cell were limited, costing valuable time. The current solution replaces the UV detectors with ionisation; the tasks of the burner control module are performed by the burner management software package from the automation system PSS 4000. Now the processes don’t just run virtually undisturbed – with rapid diagnostic options thanks to efficient visualisation in the control cabinet, which constantly displays the exact status of the 10 burners, longer downtimes are a thing of the past. http://www.pilz.com

The automated test system from Brainware Solutions tests door trims at an automotive supplier. They are part of the production line, the shortest possible test time is the top priority: only 23 seconds are envisaged for alternately loading and unloading the untested and tested door trims, plus the test itself. The requirement: to guarantee a fast-running test routine, in which operators have unobstructed, safe access to both test system racks, so they can be loaded and unloaded in time. In this case, the safety laser scanner PSENscan, combined with the configurable small controller PNOZmulti 2, offers effective but not obstructive protection, so enabling minimum test times. http://www.pilz.com

Parquet floors from oak, cherry or walnut, among them some quite special product creations, are the trademark of Scheucher Parkett. With 250 employees and a 100 year tradition, the Austrian family business from southern Styria has been producing exclusive parquet floors for the worldwide market for several decades, including for hotel suites, lofts, restaurants, bars, as well as business and conference architectures. As a manufacturer of natural, long-lasting products, the top priority for Scheucher is environmental protection and resource conservation. http://www.pilz.com

With 50 permanent staff and up to 700 seasonal and freelance workers, central Germany’s largest amusement park opened its doors in 2003, on the 27 hectare site of the former open cast lignite mine in Zwenkau. Before the gates of Leipzig, visitors to the amusement park – part of EVENT PARK GmbH – have access to eight themed worlds with over 60 attractions and shows, along with various gastronomic offers. These include several roller coasters and water rides, as well as various themed rides, a pirate ship ride, a maze and various fairground rides, a log flume ride, several more fairground rides and imaginative play areas. http://www.pilz.com

The particular focus of the safety concept: the new interface between the robot and bending machine, as this poses a variety of risks for the people located there. Firstly, no operator should stand too close while the robot is loading; secondly, the safety concept must guarantee that operator and in particular finger protection is fully reliable when inserting, or when correcting a position by hand. And: the safety device or measure must not hinder the operators as they go about their activities. As both the bending machine and operating robot already had their own separate machine and safety controllers, this project required an integrated and efficient safety solution for this interface. Due to the extensive modularity and therefore flexibility of the myPNOZ, it was possible to achieve the specification of retaining the controller environment, while increasing the productivity and flexibility of the bending machine. http://www.pilz.com
