When the beam axis is aligned, the value on the sub display (lower level) will increase.
Mount the units where the value is the largest when possible.
At this time, the laser emission warning
indicator on the sensor head will turn off or
blink. The indicator’s flashing cycle quickens
as the received light increases.
Adjust the beam axis together with the
received light level on the sub display (lower
level).
* The blinking cycle changes in stages. The faster the indicator blinks, the more accurate
the beam axis alignment is.
