Verifying Initial Emitter/Receiver Alignment
As you mount the sensors, make sure that
The emitter and receiver are directly opposite each other.
Nothing is interrupting the defined area (marked on the sensors).
The defined 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).
Angled or Horizontal Installations Vertical Installations
Verify that the
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 (that is, the lens) is level/plumb.
Defined area is square. Check diagonal measurements if
possible; see Vertical Installations, at right.
Verify that the
Distance X at the emitter and receiver are equal.
Both sensors are level/plumb (check both the Distance Z at
the emitter and receiver are equal from side and face).
Defined area is square. Check diagonal measurements if
possible (Diagonal A = Diagonal B).

side-to-side as shown.
