E3X-SD/-NA
Operating Procedure
E3X-SD@
A 7-segment display showing excess gain is provided in
addition to the orange operation indicator.
Use these when adjusting the light axis and setting the
sensitivity at setup.
The sensitivity can be set with the UP and DOWN Keys similar
to using an adjuster knob. The sensitivity can also be easily
set by using the following three teaching functions.
The sensitivity can be set to the maximum. This is the optimal
setting for resistance against the effects of dust.
Two points (one with the workpiece and the other without) are
detected, and the operating level is set to the midpoint.
Changes within a time are detected, and the operating level is
set to the midpoint between the maximum and the minimum
values of the changes. This setting is optimal for when the
workpieces cannot be stopped.
Set the TEACH/RUN selector
switch to TEACH.
Press the UP Key for 3 s min.
Set the TEACH/RUN selector
switch to RUN (start of mea-
surement).
Set the TEACH/RUN selector
switch to TEACH.
Press the UP Key with the
workpiece present.
Press the UP Key with the
workpiece not present.
Set the TEACH/RUN selector
switch to RUN (start of mea-
surement).
Set the TEACH/RUN selector
switch to TEACH.
Press the UP Key.

A bar display (with four green and one red) showing excess
gain is provided in addition to the orange operation indicator.
Use these when adjusting the light axis and setting the
sensitivity at setup.
Hold down the UP Key during
detection. Let the workpiece
pass while the key is held down.
