Implementation of EMERGENCY-STOP disconnection and protective door monitoring with monitored start via ASIsafe.

In this Safety Functional Example, the EMERGENCY-STOP control unit and a protective door are monitored via two channels by a K45F ASIsafe module. When the EMERGENCY-STOP is activated or the protective door is opened, the K45F ASIsafe module sends a signal to the safety monitor. The safety monitor then switches the downstream contactor with positively-driven contacts via the safe relay output according to Stop category 0 of EN 60204-1. A drive is shut down in this example. Before renewed switching-on via the start button, a check is carried out to monitor whether the contacts of the EMERGENCY-STOP control unit and the protective door are closed and whether the contactors have switched off.
