Remove the object, turn the distance adjuster
further counterclockwise, and find out pointoint
where the sensor changes to the light received
condition again with only the background.
When the sensor does not go to the light
received condition even if the adjuster is fully
turned clockwise, point is this extreme point in
the range.
The optimum position to stably detect objects is the
center point between and .
Place an object at the required distance from the
sensor, turn the distance adjuster gradually
clockwise, and find out point where the sensor
changes to the light received condition.
Turn the distance adjuster fully counterclockwise to
the minimum sensing range position of 0.2 m 0.656 ft
approx.

Far (Main)
Step Description Distance adjuster
Turn the Far (Main) distance adjuster fully
counterclockwise to the minimum sensing point of
0.2 m 0.656 ft approx.
Place an object at the far place at the required
distance from the sensor, turn the Far (Main)
distance adjuster gradually clockwise, and find out
point where the sensor changes to the light
received condition.
Remove the object, turn the Far (Main) distance
adjuster further clockwise, and find out pointpint
where the sensor changes to the light received
condition again with only the background.
When the sensor does not go to the light
received condition even if the adjuster is fully
turned clockwise, point is this extreme point in
the range.
The optimum position to stably detect objects for
the Far (Main) setting is the center point between

Near (Sub)
Step Description Distance adjuster
Turn the Near (Sub) distance adjuster fully
counterclockwise to the minimum sensing point.
Place an object at the near position, at the required
distance from the sensor, turn the Near (Sub)
distance adjuster gradually clockwise, and find out
point where the sensor changes to the light
received condition.
Remove the object from the near position, and place
the object for Far (Main) sensing at the sensing
position. Turn the Near (Sub) distance adjuster further
clockwise, and find out point where the sensor
changes to the light received condition again with only
the background.
When the sensor does not go to the light
received condition even if the adjuster is fully
turned clockwise, point is this extreme point.
The optimum position to stably detect objects for
the Near (Sub) setting is the center point between

Notes: 1) Turn the distance adjuster gradually and lightly with the attached
screwdriver.
If the distance adjuster is over turned or pressed heavily, it may be
damaged.
Notes: 2) The Far (Main) distance adjustment should be done before the
Near (Sub) distance adjustment. Take care that the Near (Sub)
setting distance changes with change in the Far (Main) setting
distance.
