Group lockout devices show at a glance which colleague is involved in the maintenance work and on which machine and in which machine area he or she is currently working.
Master key systems allow you to organize your group locking securely and clearly.
The principle of group lockout processes is to separate conventional personal identification locks (PIS) from the additional machine identification locks (MIS). The PIS are for every single employee and show which person is undertaking maintenance or repair work when hung up. The MIS are used to prevent reactivation of the energy supplies to the machines and installations.
