Laser Control
For Laser Control a laser transmitter is used to produce a plane
of light which becomes the grade control reference for the job
site. The laser receiver will control the screed to lay a mat
parallel to the laser beam reference.
When the laser beam is in the center of the receiver, it indicates
an on-grade signal (Figure 2-26).
Figure 2-26. Laser Control – On-Grade
As the screed is raised, the beam of light hits the laser receiver
below the center and a lower signal is indicated (Figure 2-27 on
page 2-25).
