Individual max light level display mode
The maximum receiving light level of the selected beam is
displayed.
The beam number is displayed on the top row. The maximum
receiving light level corresponding to the beam number is
displayed on the bottom row.

The fourth figure of the bottom row indicator of “(2)-1” indicates that
the approximate beam position having the minimum light level.
The beam positions of the sensor are divided in to three groups, top,
middle, and bottom, and displayed as show in the figure below. (The
bottom position means the side with power supply lines.)

2. Calculate the optimal value of ON threshold level and adjust
manually.
The sensor automatically calculates the optimal value of
ON-threshold on the basis of the minimum light level. After automatic
calculation is completed, “Good” is displayed on top row and the
calculated ON-threshold is displayed on bottom row.
Additionally, the displayed ON-threshold value can be adjusted
manually. ON-threshold can adjust in the range of 18 to 100.

One-point advice:
Adjust beams of the sensor with this function so that the
minimum receiving light level becomes higher. By doing this, the
sensor detects stably.
