Applications with safety controllers
Complex safety applications can be solved specifically using safety controllers.
In the insertion station with rotary table shown and the downstream robot station (1) all
the safety-related functions (hazardous point protection, hazardous area protection, door
contacts, emergency stop, restart) are realized using a Flexi Soft safety controller (2). The
ESPE are integrated into the safety application via EFI.

One S3000 simultaneously monitors two protective fields (1 and 2). Via EFI it signals the
states of the protective fields to the Flexi Soft safety controller (3). The safety controller
has two OSSDs for separate safe shut down. The related industrial robot is shut down by
an object in one of the protective fields. The second station continues to operate.
Advantages:
•
all safety-relevant functions in one application
•
one ESPE saved due to simultaneous protective field monitoring
•
increased availability of the system, as only the robots related to the hazardous
situation are stopped and not the complete system
