If the “Object between sensor and background” (“ObSB (Background)”) switching mode
is selected, the required settings can be taught in or set manually. These are described
in the following.
NOTE
If the sensor is unable to measure (e.g. the object is in a blind spot of the sensor,
there is too little remission or light reflection), a switching signal is output in the “Object
between sensor and background” (“ObSB (Background)”) switching mode, which corre‐
sponds to the expected behavior with the maximum distance.
NOTE
The switching mode and the settings can be changed by executing a teach function by
means of a multifunctional input (see "Multifunctional input (“MF Input”)", page 57) or
IO-Link (see "Operation via IO-Link", page 21).
NOTE
When changing between the “Object between sensor and background” (“ObSB (Back‐
ground)”) and “Switching window” (“Window”) switching modes, it is possible that the
setting for the previously selected logic and/or the switching point setting will change.
NOTE
The tolerance range of 25 mm around the switching point is a fixed setting for DT50-2
Pro, and thus cannot be adjusted, to ensure that background mode functions reliably
even over time.
6.4.1.3.2 Teachable settings (“Teach”)
Two teach methods are available for the “Object between sensor and background”
(“ObSB (Background)”) switching mode.
