E3G-L1/L3
J ADJUSTMENTS
If the sensor is not in stable operation due to color differences, make a fine adjustment of the threshold level and confirm that the sensor
operates in stable state. Refer to Manual Teaching (Fine Distance Setting.
Adjustment Steps
Distance Setting (Teaching)
Select the most appropriate teaching method in reference to the following descriptions.
La: Distance equivalent to threshold (a)
Lb: Distance equivalent to threshold (b)
The following settings are also possible:
Setting the maximum sensing distance of the sensor: Maximum distance setting.
Setting the minimum differential travel of the sensor: Minimum distance setting.
Distance from sensor to background must not exceed the values shown below during
normal one-point or zone one-point teaching.

Application
Teaching
Install, wire, and turn on the sensor.
Perform distance setting (teaching). Refer to Distance Setting (Teaching) below.
Make a fine adjustment of the threshold, if necessary.
Refer to Manual Teaching (Fine Distance Setting)
Check that the mode selector is set to RUN.

Maximum sensing distance of E3G-L3 type may differ by color of the target object
when setting distance is more than 150 mm (5.91 in).
Confirm the operation of the sensor before actual operation.
