Alignment
Wherever the visible pilot laser spot is located, the sensing/measuring laser will be located
in the same position. For fine adjustment, use bracket model SMBLT7 with the fine-adjust
accessory kit SMBLT7F (see page 22) to provide up to ±3° angle in both X and Y axes.
Aligning the sensor manually (without the alignment aid accessory) – either model:
1. Mount the sensor.
2. Activate any Programming menu item (see Figure 7), so that the pilot laser is
ON.
3. Hold the retroreflector or target object at a short distance, for example less than
1 m (3'), and verify that the laser light spot is centered on it.
4. Move the reflector or target to its final position; verify that the laser spot is still
centered on it. Adjust as necessary.
5. Tighten the sensor mountings.
Using the alignment aid. For precise alignment of retroreflective models at long
distances, the alignment aid accessory (see Figure 9) is useful. It makes the visible pilot
laser spot easier to adjust, even when it is positioned off of the retroreflective target and at
a long distance – farther than 50 m (160').
1. Mount the sensor.
2. Mount the alignment aid on the front of the sensor, over the laser emitters as
shown in Figure 9.
3. Activate any menu item (see Figure 7), so that the pilot laser is ON.
4. Aim the sensor at the reflector.
5. Rotating the barrel as needed (depending on sensor mounting location), look into
the sight hole from about 2" (50 mm) away.
6. Turn the focus screw (opposite the sight hole) to focus the spot as sharply as
possible.
7. Adjust the sensor or target position until the laser spot is centered on the target.
8. Tighten the sensor mountings, recheck alignment; if ok, remove alignment aid.
NOTE: While alignment aid scope is in place, any measurements shown on the display will
be inaccurate. Also, the Pilot LED will be visible only through the alignment aid sight hole
(red laser light will not be visible to the naked eye on the target or another surface).
Installation Notes
Some targets (those with a stepped plane facing the sensor, a boundary line, or rounded
targets) pose specific problems for sensing distances. For such applications, see Figure
10 for suggested mounting orientations.
