cy stop event is considered a complicated system.
Complicated systems are integrated using certified safety controllers or safety relays.
In this situation one device is the “master” and the rest of the devices are the “slaves”.
The Laser is considered a slave device in this configuration and its emergency stop
must be controlled by the larger machine’s safety controller. The output of the exter-
nal safety relay module closes the input to the Laser safety unit and allows the sys-
tem to clear the emergency stop state.
In this wiring example a Pilz PNOZ family safety relay module controls the Laser and
interfaces two external emergency stop buttons. In this example the Pilz device would
also control additional emergency stop functions outside of the Laser using expan-
sion contacts. The more devices which must be implemented the more expansion
contacts must be added to the Safety Relay Module. Any suitable IEC13849-1 com-
pliant safety relay controller is acceptable as long as it is implemented in this manner.
The end user is responsible for verifying compliance of the machine as a whole.
