10 Structure and function
10.1 Description
The guard-locking mechanism consists of casing with an integrated lock, casing with a blocking de-
vice, an integrated lock and a personal key, and an actuator. To remove the personal key the coded
key is inserted and turned in this lock. The personal key can then be turned and removed. The block-
ing device releases the actuator; this can by removed by turning it.
The guard-locking device HST-TZ2 ensures that the inserted and turned release key can only be re-
moved if the safeguard is closed, and the actuator is inserted, turned, and interlocked by the personal
key.
