Teach-in method
Teach Operating level 1 Operating level 2
Standard Teach Teach on object:
With this teach event, the object is located in front of
the sensor. The switching threshold is set by the
teach so that the object is detected with tight signal
reserve R. Thus, the object is detected even if the dis-
tance increases by the value r with respect to the
distance during the teach.
Teach on background:
This teach is only suitable for applications with a fixed
background. The teach is performed directly on the
background without an object. The switching thresh-
old is set to a value that is just above the background
signal (signal reserve R). Thus, objects can be
detected up to a distance of r in front of the back-
ground.
