Environmental Conditions
(i.e. roll coolant, or coolant
mist, spray and fume) are
adversely affecting the
measurement.
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.
Valid LED is not illuminated Incorrect sensor orientation Rotate the sensor so that it matches the
diagram in the
Aligning the Gauge
section.
"Valid Data" LED is flickering ON
and OFF Dirty quick change window
1. Check the quick change window for
contamination.
2. Clean or exchange quick change
