Environmental Conditions (i.e. roll coolant, or coolant mist, spray and fume) are adversely affecting the measurement.

Valid LED is not illuminated Incorrect sensor orientation

"Valid Data" LED is flickering ON	Dirty quick change window
and OFF

verify that the gauge is at the correct standoff distance.

2.Verify that the gauge is mounted in the correct orientation.

3.Check the E setting – must be set to 31 to enable all signal ranges.

4.Check Minimum and Maximum Velocities, and set to large negative and positive values respectively.

Result C: The gauge emits no (zero) laser beams.

1.Make sure the laser interlock is closed, and that the LASER ON LED is illuminated.

2.Make sure the shutter interlock is closed, and that LaserTrak indicates that the beam shutter is open.

3.Check the gauge temperature, and connect coolant lines if required.

4."Ring-out" the cable to make sure it isn't damaged.

Result D: The gauge emits only one laser beam.

1.Contact Beta LaserMike for assistance.

1.Inspect the environmental conditions at the measurement area.

2.Check the operating conditions of the compressed air utilities.

3.If using a beam path air purge, check the clean make-up air duct for any damage (holes and tears) that may be drawing in contaminated make-up air from the mill environment.

4.Install proper beam path air purge and/or air wiping (air knife) system to keep optical beam path and measured surface clear and clean.

Rotate the sensor so that it matches the diagram in the Aligning the Gauge section.

1.Check the quick change window for contamination.

2.Clean or exchange quick change
