Adjustment Method
Adjustment Method 1
1. Set the pointer of the sensitivity adjuster to the center of its
revolution range.
When the quantity of light reflected from the object is greater than
that from the background object, adjust the sensing distance in the
following sequence:
2. Turn the distance adjuster fully counterclockwise to the “S”
position.
1. Set the pointer of the sensitivity adjuster to the center of its
revolution range.
3. Set the sensing object in position.
2. Turn the distance adjuster fully counterclockwise to the “S”
position.
4. Turn the distance adjuster gradually clockwise to a point
where both the LIGHT and STABILITY indicators light. Fix the
distance adjuster at that point.
3. Set the sensing object in position.
5. Adjust sensitivity.
4. Turn the distance adjuster gradually clockwise to a point
where both the LIGHT and STABILITY indicators light. Fix the
distance adjuster at that point.

following sequence:
1. Set the pointer of the sensitivity adjuster to the center of its
revolution range.
2. Turn the distance adjuster fully counterclockwise to the “L”
position.
3. Remove the sending object.
4. Turn the distance adjuster gradually clockwise to a point
where both the LIGHT and STABILITY indicators light. Fix the
distance adjuster at that point.
5. Adjust sensitivity.
