2.7.3 Active Safety Input Function (Control Category 4)
The safety input function can be activated when connecting a safety contact to the safety input
1 wire (gray) and the safety input 2 wire (gray/black) of the emitter; for details see "Safety Input
Function" on page 63.You can also connect a safety sensor, if you use the handy controller
SFC-HC (optional). By connecting a safety sensor to the safety input 1 (gray) and the safety
input 2, this device and the safety sensor can be used in a series connection.
For details, see page 84.
