Unlike the conventional models, the E3S-C scarcely has sensitivity variations between products. Therefore, you need to make the
above adjustment on only one diffuse reflective model of E3S-CD that will be used for detection under the same conditions, and
match the indicator points of the other diffuse reflective models of E3S-CD with the above adjusted one. (You need not match the
sensitivity of each sensor.)

Note: The through-beam and retroreflective models are different in sensitivity
adjuster shape.
Place a sensing object in the predetermined position, turn the
OFF Æ ON
sensitivity adjuster clockwise (increase sensitivity) until the
incident indicator (red) is turned ON, and define this position
as (A).
Light indicator

Remove the sensing object, turn the sensitivity adjuster fur-
ther clockwise until the incident indicator (red) is turned ON
ON Æ OFF
by a background object, and define this position as (B). Turn
the sensitivity adjuster counterclockwise (decrease sensitivi-
ty) from (B) until the incident indicator (red) is turned OFF,
Light indicator
and define this position as (C). When there is no background
(red)
object, define the maximum adjuster position (Max) as (C).
Set the adjuster in the middle of positions (A) and (C) (opti-
mum sensitivity setting). Also make sure that the stability in-
ON ´ OFF
dicator (green) is turned ON when there is an object and
when there is no object.
Light indicator
When the indicator is not turned ON, recheck the detection
(red)
method since there is a little allowance.
