OPTICAL BEAM SYSTEM
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.
The indicator of the Retro- reflective Model with the timer function is lit in the same way as for the Through-beam Model.
The indicator of the Diffuse-reflective Model with the timer function is lit in the same way as for the Through-beam Model.
Move the emitter and receiver horizontally and vertically, and locate them to the center of the range in which the receiver indicator is lit.
As with the Through-beam Model, adjust the reflector and Sensor. Since the directional angle of the E3JM and E3JK Retro-reflective Models is 1 to 5 degrees, pay careful attention when adjusting the Sensor.

Sensitivity Sensitivity Sensitivity
(1) If a sensing object is present as shown above, turn the sensitivity 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.
· The sensitivity adjuster may be damaged if an excessive
force is applied.
