Abstract
A safety system includes a safety unit and at least one safety related participant which comprises a protective device and a first and a second interruptible signal transmission path which can be interrupted together on the occurrence of a non-secure state of the protective device. The safety system includes at least one test signal path which runs through the safety related participant to a safety input of the safety unit starting from an output of the safety unit and comprises at least one of the first and the second interruptible signal transmission paths. The safety related participant comprises an interruption switch arranged in the test signal path and an evaluation unit which is connected to the first signal transmission path and/or to a first switching signal output of the protective device and to the second signal transmission path and/or to a second switching signal output of the protective device.
