AS-Interface Safety at Work - SCHMERSAL - #6

6 Hydro Aluminium, Raufoss Fast configuring, higher transparency The Raufoss plant of the Norwegian Hydro concern produces every year thousands of aluminium shock absorbers for the automobile industry. As production is regarded, the company considers safety of paramount importance as well: all safety components at the machines and plants are equipped with AS-Interface Safety at Work (AS-i SaW). With AS-i SaW, Hydro Aluminium could save a lot of money as the wiring costs were regarded. Another important issue was the simplified configuration of the safety appliances through PC. The safety functions simply can be chosen and configured by Drag & Drop and then can be copied to multiple safety switching appliances if required. Ola Överstad, project manager of the New Process & Production Equipment Division at the Raufoss plant: „The increased transparency was one of the main reasons why we chose the AS-i solution. At all times, the asimon software keeps me informed about newly installed safety components. This is particularly advantageous when transferring the safety systems from one shift to another. In this way, the safety engineers always have 100% control over the system.“ STIHL AG & Co., Waiblingen Production line with global safety concept For its new chain guide production unit at the Waiblingen plant, STIHL, world leader in the production of chain saws, chose an innovative safety concept. All stations of the production line – both the “in-house” manufactured and the nine third-party machines – should have a uniform safety standard and communicate through AS-i SaW. This concept was successfully implemented. STIHL requested its suppliers to use the AS-i SaW switchgear from Schmersal. More than 110 safety switching appliances were installed: 68 by Stihl, 45 by the suppliers. Basically two types are used: the AZM 161 AS solenoid interlock and the BNS 33 AS safety sensor with integrated ASi SaW interface. Paul Giesinger, Electrical Construction Manager of the „Machine and Device Centre“ from STIHL AG & Co: „The ASi SaW components only require a minimum of wiring compared to the traditional safety switching appliances. The comfortable software moreover allows for a smooth parametrering of the safety functions.“ AS-Interface SaW AS-i Safety at Work AS-Interface Safety at Work®
