Options Key
Laser Intensity: An “X” in this column indicates that the laser signal
received on the laser head PSD (Position Sensor Detector) is out of its
factory specified limit (either too high or low). This could be due to a
beam adjusted in such a manner that the beam isn't hitting the target,
a blocked laser beam, an internal error in the laser head, or a laser
power transmitted from the other laser head which is too low. When
the head is in this state, no data is being acquired. First make sure that
the laser beam from the opposite laser head is properly adjusted so it
hits the PSD of the laser head. Refer to “Center the Laser Beams” on
page 4-42 for more information. If the adjustment isn't the problem,
make sure the laser beam isn't being blocked by an obstacle (e.g.
cable, dirt or grease on the laser and PSD lenses, dust particulate in
the air, etc.). Also, make sure the laser head is being operated within
its specified temperature limits (i.e. temperatures greater then the
specified limit can result in a reduced laser power output). Refer to
Appendix C for operating limits. Contact CSI Customer Support if
you are unable to resolve the problem.
Laser Current: An “X” in this column indicates that the circuit driving
input current for the laser signal being transmitted from the laser
head is out of its limit (either too high or low). This should only occur
if there was an internal error in the laser head. When the head is in
this state, no data is being acquired. Contact CSI Customer Support
if you experience this problem.
Note
The circuit driving input current for the laser signal being
transmitted and the laser power for the laser signal being trans-
mitted are not the same. It is possible for the laser signal power
being transmitted to be low and still have the circuit driving
input current for the laser signal being transmitted be within
factory specified limits.
