J NO-OBJECT TEACHING
Note: 1. To detect dark objects in front of bright backgrounds, set the operation mode selector to D. ON.
J SENSITIVITY ADJUSTMENT
Combination of the E3X-NT/E3X-NM and Fine Through-beam Fiber Units (E32-T22S/T24S/T84S)
No-object Teaching
Press the teaching button once with no object in the sensing area.
Note: If detection is not stable after no-object teaching, perform

time the green indicator will be lit.
Operation
Locate the sensor head within the rated sensing range with the E3X-Nj.
Set the mode selector to TEACH.
The flashing function of the E3X-Nj 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-Nj will beep.
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.
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.
