The contact chain-type safety edge in a correspondingly designed configuracion meets category 3 of EN 954-1 – even he sensor part. A model meeting highest category 4 is also available. Double-channel design or redundancy is not necessary for this system, since the failure mode analysis made by the German test house BG has shown: a single fault does not lead to a loss of the safety function. This permits a simple construction of the system.

SAFETY INTERLOCKS and bolt interlock HST-B

High safety.

Such guard locking devices are for instance key-operated mechanical interlocks, also called bolt interlock HST-B. They are based on the easy-to-understand premise that a key cannot in two places at the same time - it can for instance be inserted in a switch OR be used for opening a guard.
Another safety-relevant feature of bolt interlock HST-B is that a key can only become free in a safe condition, when there are no hazards - a switch is turned off, a guard interlock is closed and locked. The big advantage of the system is the fact that a certain sequence of steps can be predetermined when designing the system. It is not possible to deviate from this sequence - thus a high degree of integrity is achieved. So virtually any hazard can be eliminated.

Switch HST-S and bolt interlock HST-B

The bolt interlock HST-B is used for isolating the machine, in order to permit safe access. After the voltage has been switched off, the previously trapped key can be removed and used for the next step in the sequence, e.g. opening a guard. The unit is available as an enclosed (IP 65) or a panel mount version. Versions with multiple locks (enclosed version sheet-steel up to 4, panelmount version up to 10) are also available. Further, versions in explosion-proof enclosures (ATEX zones 21 & 22 and 1 & 2) can also be supplied.
