The new maintenance safeguarding “key-in-pocket” system from Pilz (Canton, MI) protects unauthorized machine restart, allowing maintenance work to be carried out safely. Digital maintenance safeguarding is based on the access permission system PITreader and guarantees safety and industrial security as only authorized personnel can access the plant or machine during the maintenance process.
Larger plants often have a number of danger zones, which are protected using safety fences. This places demands on safety and it is important that only authorized personnel have access for maintenance work. At the same time, it is essential to ensure that nobody is left in the danger zone when the plant restarts.
With “Key-in-pocket,” Pilz has created a digital maintenance safeguarding system which is flexible to meet the demands of both safety and industrial security. “Key-in-pocket” ensures that the machine does not restart while maintenance work is being done and that unauthorized personnel do not gain access. The solution offers safety in the face of a hazardous restart and - at the same time - industrial security, because it is impossible to tamper with the maintenance work.
