No-object Teaching
Note
1.
After no-object teaching is performed, the first to fifth incident with the cor-
responding sensing objects will be sampled to adjust the sensitivity.
2.
The E3X-N
@
will be ready to detect objects in approximately one second
after the mode selector is set to RUN.
With/Without-object Teaching
Procedure
Operation
E3X-NT
E3X-NM
1
Locate the sensor head within the rated sensing range with the E3X-N
@
.
2
Set the mode selector to TEACH.
3
The super-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.
5
Set the mode selector to RUN. No-object teaching will be set
when the first sensing object passes through the sensing
area.
The teaching indicator (red) turns green (automatically turned
off in one second).

Select the logical output required with the operation mode
selector.
