The flashing function of the E3X-N will be activated. Therefore,
adjust the optical axes so that the tip of the emitting fiber will be lit. If
the optical axes are divergent, the tip of the emitting fiber will flash
and the built-in buzzer of the E3X-N will beep.

4 Press the teaching button for 0.5 to 2.5 seconds without a sensing
object. In the case the E3X-NM, select a channel with the channel
selector and press the teaching button, at which time the stability
indicator for the selected channel will flash.
The teaching indicator (red) is lit.
The built-in buzzer beeps once.

Note: 1. To detect dark objects in front of bright backgrounds, set the operation mode selector to D. ON.
2. If the set distance is very short (i.e., 0 to 12 mm for the E32-TC200 and 0 to 4 mm for the E32-DC200), no-object teaching is
not possible due to excessive light, in which case, perform with/without-object teaching.
3. If the teaching button is pressed for more than three seconds, the sensitivity of the E3X-N will be set to maximum, at which
time the green indicator will be lit.
4. The E3X-N will be ready to detect objects in approximately one second after the mode selector is set to RUN.
