Installation
3.2 Mechanical Alignment
Mount the emitter and receiver in their brackets and position the
windows of the two units directly facing each other. Measure
from one or more reference planes (e.g., the building floor) to
the same point(s) on the emitter and receiver to verify their
mechanical alignment. Use a carpenter’s level, a plumb bob,
or the optional LAT-1-SS Laser Alignment Tool, or check the
diagonal distances between the sensors, to achieve mechanical
alignment.
When alignment is difficult, a LAT-1-SS tool is useful to assist
or confirm alignment, by providing a visible red dot along the
sensor’s optical axis (see Figure 3-3). Snap the LAT-1 clip onto
the sensor housing, turn on its laser emitter and use a strip of
retroreflective tape at the opposite sensor to see the dot.
Also check “by eye” for line-of-sight alignment. Make any
necessary final mechanical adjustments, and hand-tighten the
bracket hardware. See Sections 3.4 and 4.2 for further alignment
information.

Angled or Horizontal Installations – verify that:
• Distance X at the emitter and receiver are equal.
• Distance Y at the emitter and receiver are equal.
• Distance Z at the emitter and receiver are equal from parallel
surfaces.
• Vertical face (i.e., the lens) is level/plumb.
• Sensing area is square. Check diagonal measurements if
possible; see Vertical Installations, at right.
Vertical Installations – verify that:
• Distance X at the emitter and receiver are equal.
• Both sensors are level/plumb (check both the
side and face).
• Sensing area is square. Verify diagonal measurements if
possible (Diagonal A = Diagonal B).

Verify that:
• The emitter and receiver are directly opposite each other,
and nothing is interrupting the beams.
• The sensing area is the same distance from a common
reference plane for each sensor.
• The emitter and receiver are in the same plane and are
level/plumb and square to each other (vertical,
horizontal, or inclined at the same angle, and not tilted
front-to-back or side-to-side).
