Test rigs for laboratory use are typically equipped with a PLc rated safety system. This is upgraded to PLd for systems requiring frequent operator interaction. Systems used in production environments usually come with a PLe rating.
Safety systems are implemented either by PILZ safety relays or a safety SPS. The second option is used for sophisticated systems with numerous input signals and advanced assessment algorithms. Safety systems comprise various mechanical, hydraulic and electric safety features, including a safety fence, safety manifold, e-stop button, emergency lock and others.
As an important part of every test rig, INOVA safety systems are carefully designed by engineers based on a comprehensive risk analysis accounting for all safety relevant factors, including the intended use. The risk analysis and declaration of conformity are provided with all INOVA test rigs.
- Single test rig PLc, PLd or PLe rated safety systems implemented via INOVA control electronics
- Multiple test rig safety systems implemented via INOVA control electronics with independent safety circuits for each test rig
- Independent safety systems – not part of INOVA control electronics
- Safety systems connected with power pack station safety circuits
- Risk analysis and comprehensive safety system design
- PILZ or safety SPS safety control unit
- Safety manifolds for PLc, PLd and PLe safety ratings
- Safety fence
- Safety design of loading frames, actuators and other movable parts
