User set parameters Section 4-3
• Window evaluation
Measured objects are detected only in the measurement window between
the two user set switching points (switching zone). Objects outside of this
measurement window in the foreground and in the background are
ignored.
Window evaluation involves logical AND combination of the FGS and
BGS modes.
Figure 6 Window evaluation
Accordingly for output 2 the switching points C and D are set.
4-3-2 Output function
The output function can be set separately for both outputs:
• Light on (factory default)
The output is active when a measured object is detected.
• Dark on
The output is active when no measured object is detected.
4-3-3 Switching points
The switching points can be set on a positioned measured object or can be
user set by input of switching points.
In the window evaluation mode, two switching points must be defined for
each output.
In the FGS or BGS mode, only one switching point needs to be defined for
each output.
4-3-4 Output switching
Output switching can be user set jointly for both outputs:
• PNP, plus-switching, open collector (factory default)
• NPN, minus-switching, open collector
• Push-pull, complementary, plus/minus-switching
