External Teach-In
If the control panel is inaccessible, the Sensor can be configured via the external Teach-In input (pin 1).
The last Teach-In mode selected at the control panel is always active (i.e. Two-Point or dynamic Teach-In).

External Dynamic Teach-In
Objects to be scanned move at a constant speed.
If no continuous alternating back and forth between the marking and the background occurs during recording,
the spot must be aligned to the background when the Teach-In mode is first initialised.
