■ Indicator
Lights when the switch is activated (output transistor ON) irrespective of Light-ON, Dark-ON.
Lights when the incident light or shaded light is good enough for stable level.
■ Optical axis adjustment
Swinging the light source and receiver up and down and right
and left when no objects exist, set and fix the light source and
receiver to the center within the range where the operation
indicator (orange) is lit or is turned off (Dark-ON). At the same
time make sure that the stability level indicator (green) is lit.

Transmission type
When carrying a normal detection, set the sensitivity adjuster at the maximum sensitivity value by turning it fully clockwise.
Sensitivity adjustment is necessary for the following cases.
Carry out the sensitivity adjustment as follows. (When excessive power is added to the sensitivity adjuster, it might be damaged.)
• Transmission type: To detect translucent or minute objects
• Reflection type: To detect objects with inadequate contrast

Step
By turning the sensitivity adjuster,
obtain point A and B at that the status
of the operation indicator changes.
Unless the status changed, two points
at finishing turning the sensitivity
adjuster will be point A or B.
An intermediate position between point
A and B will be the optimum position.
