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 door interlocks

High safety.

Door Interlocks: Such guard locking devices are for instance key-operated mechanical interlocks, also called trapped-key systems. 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.
Door Interlocks: Another safety-relevant feature 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.
