Self-diagnosis function
Relationship between quantity of light received, output and
indication lamps
The self-diagnosis function warns of the decrease in the light value received due to the
deflection of the optical axis or dirty lens surfaces.

■ Time char t of the self-diagnosis function
The self-diagnosis output is OFF when the quantity of light received is between the range
66 to 115% of the operating level due to the deflection of the optical axis or buildup of dirt
and this situation as continued over the delay time.

Setting-up procedure
Optical axis adjustment
■ Diffuse type
■ Separate (through-beam) type
•
•
Visually align the sensor position
The characteristics of detection depend on the
material and shape of the target object.
•
Position the tips of the optical fibres so that they face
each other and encompass the sensing position.
The incident light indication lamp lights (red) when
the optical axes are aligned. Check also that the stable
operating level indicator (green) lights.
•
•
Upon detection of the target object, the incident light
indication lamp lights (red). Check also that the stable
operating level indicator (green) lights.
Sensitivity adjustment
A fine and a coarse sensitivity adjustment permits accurate
adjustment.
■ Procedure of sensitivity adjustment
•
When carrying out a normal detection, set both dials
at the maximum sensitivity value by turning them fully
clockwise.
•
When a photoelectric switch is used for detection of an
object with inadequate contrast, sensitivity adjustment
should be carried out.
Carry out the sensitivity adjustment as follows.
