Pilz Digital Maintenance-Safeguarding System
an Efficient Alternative to Mechanical Lockout-Tagout
The new maintenance safeguarding “key-in-pocket” system from Pilz, Canton, MI, promises to protect metal formers from unauthorized machine restarts, allow- ing maintenance work to be carried out safely. The digital maintenance-safeguard- ing solution is based on the Pilz PITreader RFID-based access-permission system and guarantees safety and industrial secu- rity, as only authorized personnel can access the plant or machine during the maintenance process. Digital maintenance safeguarding is specifically designed for machines with danger zones protected via safety fences, providing an efficient alternative to mechanical lockout-tagout systems, say Pilz officials.
With key-in-pocket, Pilz has created a flexible digital maintenance-safeguarding system to meet safety and industrial- security demands. Key-in-pocket ensures
that the machine does not restart while maintenance work is underway, and that unauthorized personnel do not gain access.
Users are given an RFID key with their individual permissions, which can be read on the safety gate using PITreader. This way, one or more users authorized for maintenance work can authenticate them- selves. At all times, the operator knows who has access for which tasks; temporary permissions also can be assigned.
After successful authentication, the system controller stores a personalized security ID, kept in a safe list. The machine then can be shut down, the safety gate opened and the machine accessed. During this time, the RFID keys remain with the respective users. Once maintenance is complete and people have left the danger zone, everyone signs out. The security
IDs are removed from the safe list on the Pilz controller, and the machine can be restarted.
