Production-adapted safety system for at least one automatically operating production unit 11, for example a robot. The system includes at least one safety circuit in which there is at least one safety device 10, for example in the form of an edge protector, a surface protector, a holder device 29, etc. The production unit 11 is controlled by a computer 32 or the like. Each safety device 10 is connected to at least one input of a safety module 28 comprising twin stop relay circuits A, B and monitored for short circuits and interruptions. Arranged parallel to the stop circuits A, B there is a re-set relay circuit C which is provided with a re-set device 31 which has to be both closed and opened before the outputs from the twin stop circuits are closed. <IMAGE> |
