4.5 Using the Safety Input Function
!
As safety sensor, use a sensor which incorporates a
crossover short-circuit function in the control output
and connect both the safety input 1 wire (gray) and
the safety input 2 wire (gray/black). If only one wire
is connected, the device may not operate normally.
The safety light curtain incorporates the safety input function. This function controls the control
output (OSSD1/2) of this device by receiving the detection signal of a safety contacting point
which is connected to the safety input 1 or 2.
