Operating Procedures: Photoelectric Sensors

Remote Control Function (Bank Selection, Mark Registration, Threshold Adjustment)
In RUN mode and ADJUST mode, remote operation can be performed by inputting the signals in the following table for the remote
control input/answer-back output. There will be answer-back output for 0.3 s if the signal is correctly received.
Only one-point teaching can also be operated with manual input.
(Provide input for 1.5 s min.)
Timing Chart
*If consecutive signals are to be sent, allow an interval of at least 2.5 s after the
signal is input, as in the figure above.
Example of Ladder Programming
Control signals can be created using the example of ladder
programming shown in the following figure.

0.1 s
E3S-CR62/67
Sensitivity Adjustment
The Sensor and reflector can be moved horizontally and vertically to set them in the center of the illumination area of the red incident light indicator,
allowing the operator to check whether the green stability indicator lamp is lit.
