Crystal clear access control

When constructing a new components testing laboratory, system provider for building envelopes Schüco took the opportunity to integrate a contemporary concept for Safety and Security. In future, each test bench should comply with the current requirements of EC Directive 2006/42/EC. The idea was a one-stop permission management system with central rights administration, including safety infrastructure. The requirements: one system that unambiguously controls who has access to the respective test bench. It should also issue operating permissions based on qualifications and personal profiles. Today, an integrated safety concept from Pilz protects people from hazards, minimises operating errors and manipulations, and reduces plant downtimes. At its heart is the operating mode selection and access permission system PITmode flex.

The test applications pose different requirements on Safety and Security, based on the size and scope of the test. The aim was to be able to customise these individually depending on the plant. Schüco defined three operating levels: level 1 only allows access to the plant once it has stopped. Level 2 key holders are allowed to carry out inspection tasks or to run applications at reduced speed. Operators with level 3 can access individual data parameters. These requirements are implemented using the operating mode selection and access permission system PITmode flex. Operators have their individual access permission stored on an RFID transponder. Safety locking devices PSENslock and non-contact magnetic safety switches PSENmag secure the gates. The higher-level control instance is the modular small controller PNOZmulti. This holistic safety concept ensures that testing processes now run smoothly.

• All test benches now with a uniform, customisable system for Safety and Security
• With one key, operators have different permissions for a variety of plants
• The test benches meet the current specifications of the EC Directive 2006/42/EC

The Schüco Group has its headquarters in Bielefeld and offers high-quality system solutions for building envelopes. The product portfolio includes windows, doors, façades, ventilation, security and sun shading systems, as well as intelligent, networkable solutions for residential and commercial buildings. Founded in 1951, the company now operates in more than 80 countries and employs around 6,800 people. Schüco continuously subjects components as well as window and façade elements to various mechanical function, load and stability tests. In addition, there are test procedures that simulate climate and weather events.
