A If there is a teaching error after performing remote two-
point teaching with E3X-NL, try performing remote two-
point teaching again. If the remote RUN/TEACH input is
set from L to H after the teaching error, the thresholds set
with E3X-NL will not be refreshed.
B When remote teaching is not performed, cut the pink and
purple wires at the root of the cable or connect them to the
+ side (+V) of the power supply, and cut the orange wire
at the root of the cable or connect it to GND (0 V).
C About 1 s after remote teaching is over, the Sensor is
made ready to detect an object.

EEPROM Write Error
If a write error occurs (buzzer beeps, red and green teaching
indicators flicker at the same time, operation and stability indi-
cators flicker) due to power-off, static electricity or other noise
in the teaching mode (until the initial operation level compen-
sation completion of teaching without object), perform teach-
ing again with the unit button.
Note: If a memory error occurs, the red and green teaching indicators flicker at
the same time and the stability indicator flickers, unlike the teaching error.
