„ Bar LED monitor (sensor head)
When A, which is closer to the amplifier, is ON, the monitor displays the excess gain
of output A. When B is ON, the monitor displays the excess gain of output B.

Adjust the beam spot size by turning the
focus ring. After completing the
adjustment, fix by turning the focus lock
screw.

The current value of received light
intensity is displayed relative to the
setting value, within the range -15% to
+15%.
Detection is generally stable when the
received light intensity is at least ±10%
different to the setting value, which is
represented by the center bar of the
LED monitor.
The illustration shows
an example of a
received light
intensity of +5%.

Setting value
Light is steadily

The indicator turns on according to
the difference between the
received light intensity and the
setting value. The current level of
detection stability can be
determined from this difference.
If detection becomes unstable (light cannot be "steadily received"
or "steadily interrupted") due to a change in the surroundings or
the target, or for any other reason, readjust the sensitivity.
