2.5 150 m and 300 m Laser Installation and Wiring
Intelli-Protect
150 and 300 m Configurable systems contain Class 1 measurement and Class 2
®
alignment lasers with visible and invisible laser radiation. Do not look at the beam. The irradiation can
lead to irritation especially in a dark environment. Do not open the laser unit to service it since there are
no serviceable parts inside.
The Intelli-Protect
150 m and 300 m Systems measure the distance between the trolley or bridge
®
mounted laser lens and the target reflector. There must be no projections on the crane that may extend in
front of either (or both) the laser unit or the reflector.
Make sure the laser is mounted such that nothing can come between the laser's view of the reflector.
Determine the mounting position for the laser and the target such that the center of the laser's faceplate
and the center of the reflector are the same distance above the plane the crane rails are in. The laser and
reflector center point should also be the same distance from the rails. This is the most important part of a
successful installation since the laser beam must stay on the reflector at all range points anywhere in the
bay.
NOTE: Alignment (pointer) laser will blink at approximately 1 hz when target signal is lost, and
will flash for an additional 2 minutes before deactivating automatically.
When mounting reflectors, keep the alignment beam (laser pointer) completely on target, and do not allow
a beam to partially fall off a reflector's edge. The alignment laser should be enabled during setup.
The table below may be used to identify how far off center a beam may stray before a partial loss of signal
will occur.
Example: At 150 m, the infrared measurement beam diameter is 35 cm. The total reflector width of the
recommended 2-wide setup is 122 cm (61 cm reflector). There will be 43.5 cm on each side of the
measurement beam on a perfectly centered system. This is the off-center horizontal tolerance value.
Example Horizontal off-center tolerance: (122 cm - 35 cm) / 2 = 43.5 cm
