5. Alignment
Prism Targeting
Prism targeting should only be used when the laser cannot be seen, for instance in
high ambient lighting conditions or over very long distances.
1. Ensure targeting setting switch is in the right
hand position.
2. Move the slide switch to the left position. The green
and amber LEDs will flash together for a few seconds
to show the detector has started Prism targeting.
If the green LED stays illuminated the Detector is receiving
enough light back from the Reflector. Cover the reflector – if
the green LED goes off then the light being received by the
Detector is coming from the Reflector and you can now
proceed to the Alignment stage. If the green LED stays
illuminated with the reflector covered then the light received
by the detector is being reflected by some other object in
or around the beam path. Take care to make sure there are
no reflective objects within 0.5m of the centre of the beam
path, and try Prism Targeting again.
The amber LED will flash every two seconds if the Detector is not receiving enough
light from the Reflector. The number of flashes indicate how strong a signal it is
receiving. Using the direction buttons, move the detector in one axis until the amber
flashes increase. If the number of flashes stays the same, then keep going in the
same direction. If the number decreases then reverse direction. Once the number of
flashes starts to increase then keep going until either:
The green LED comes on, at which point cover the reflector as described above
•
The amber flashes start to decrease again, at which point reverse direction for 2
•
steps and perform the same process in the other axis
If Prism Targeting has been performed on both axes and the green LED is still not on
then ensure that the correct number of reflectors for the range has been used, that
the distance has not exceeded the maximum (120m/394ft) and that the reflector and
detector are parallel to each other.
Manual Alignment
Manual alignment should only be used when Automatic alignment has failed even
after it has been verified that the correct number of reflectors have been installed
and the correct clearance around the beam path has been given.
Perform targeting as previously described.
Ensure Setting Switch 1 is in the right-hand position, and move the Slide Switch to
the right-hand position.
The green and amber LEDs may flash if the detector needs to perform an initial
power adjustment.
