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).
