Operating Procedure
E3X-SD
1 Sensitivity Setting
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 two teaching functions.
2-1. Teaching with/without a Workpiece
Two points (one with the workpiece and the other without) are
detected, and the operating level is set to the midpoint.
Light level is also automatically set to the optimal value.

2-2. Automatic Teaching
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. Execute automatic teaching
again if the incident light level is not automatically set to the
optimal value.
Operation description
Press the TEACH button for 3 s min. Let the
