Through-beam Models
For a E3JM with the timer function, the indicator will be lit when
incident light is received while the mode is switched to Light-ON,
and the indicator will be lit when light is interrupted while the mode
is switched to Dark-ON.
Move the Emitter and Receiver horizontally and vertically, and
locate them to the center of the range in which the Receiver indi-
cator is lit.
Retro-reflective Models
The indicator of the Retro-reflective Model with the timer function
is lit in the same way as for the Through-beam Model.
As with the Through-beam Model, adjust the Reflector and Sen-
sor. Since the directional angle of the E3JM Retro-reflective
Model is 1 to 5 degrees, pay careful attention when adjusting the
Sensor.
Diffuse-reflective Models
The indicator of the Diffuse-reflective Model with the timer func-
tion is lit in the same way as for the Through-beam Model.
1. If a sensing object is present as shown above, turn the sensi-
tivity adjuster clockwise to increase the sensitivity. Point (A) is
where the indicator is lit.
2. Remove the sensing object and turn the adjuster clockwise.
Point (B) is where the indicator is lit by background objects.
3. Turn the adjuster counterclockwise to decrease the sensitivity,
starting from the point (B). Point (C) is where the indicator is
lit.
4. The center point between the point (A) and point (C) is the
optimum position. If the indicator is not lit by the background
object at the maximum sensitivity, set to the center point
between the point (A) and the maximum sensitivity.
Note: The sensitivity adjuster may be damaged if an excessive force is
applied.
