5.3 Teach-in error
When attempting to teach in a piston position that is
outside of the detection area (insufficient magnetic field
strength), the yellow and orange LED flash alternately for 3
seconds after releasing the button.
In this case, the previously taught-in value of the
corresponding switchpoint is not overwritten, but remains
unchanged.
