No-object Teaching
With/Without-object Teaching
Press the teaching button once with no wafer in the sensing area.
Press the teaching button once with no wafer in the sensing area.

Note: If detection is not stable after no-object teaching, perform
with/without-object teaching.

Maximum Sensitivity Setting
Note: The sensitivity of the E3X-NT and E3X-NM are set to maximum before shipping. When resetting the sensitivity of the E3X-NT or E3X-
NM to maximum after no-object teaching or with/without-object teaching, follow the steps described below.
Procedure

Operation
Locate the sensor head within the rated sensing range with the E3X-Nj.
Set the mode selector to TEACH.

The super-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.
4
Press the teaching button for three seconds minimum with or without
a sensing object. In the case of the E3X-NM, select a channel with the
channel selector, at which time the stability indicator for the selected
channel will flash.
TEACH
The teaching indicator (red) turns green.
The built-in buzzer beeps once when the color of the teaching
indicator is red.
The built-in buzzer beeps continuously when the color of the teaching
indicator is green.
Note: The built-in buzzer will stop beeping when the teaching button is
no longer being pressed.
5
Set the mode selector to RUN to complete the sensitivity setting.
TEACH
The teaching indicator is OFF.
Note: When the sensitivity is set to maximum, the sensitivity will be au-

tomatically adjusted regardless of the set distances of the fibers
or light.
