Abstract: The present invention relates to a safety controller for the safety-directed monitoring and control of a machine, said safety controller having at least one monitoring input that is configured to receive a detection signal from a protective device; at least one control output that is configured to output a shutdown signal to the machine to be monitored and to be controlled; at least one bypass input that is configured to receive a bypass demand from an independent control system. The invention further relates to a safety system having a safety controller and having at least one protective device connected to the safety controller.

Abstract: A safe control apparatus (10) for adjusting the stroke length of an eccentric press (100), wherein the eccentric press (100) has a plunger (102) that is driven via a connecting rod (104) by an eccentric system (106) that comprises an eccentric shaft (108) and an eccentric bushing (114) that can be released from one another and then rotated against one another for the adjustment of the stroke length; wherein the control apparatus (10) has an encoder (12) for determining the rotational position of the eccentric shaft (108) and a control logic (10) to generate a first switching signal at at least one first rotational position (BDC, TDC). The control logic (10) is here configured to automatically readjust the first rotational position (BDC, TDC) on an adjustment of the stroke length.
