Locking the teach button via the input IN (Pin 2, not for KRTM 3B/L6…)
A static HIGH signal (≥ 20ms) at the teach
input locks the teach button on the sensor if
required, such that no manual operation is
possible (e.g., protection from erroneous
operation or manipulation).
If the teach input is not connected or if there is
a static low signal, the button is unlocked and
can be operated freely.
