Symptom Probable Cause Comments
Temperature readings
are too high Faulty IS 6 Advanced /
IGA 6 Advanced Contact LumaSense. See
section
1.5
Electrical noise in lead wires caused
by intense magnetic fields and/or
improper selection of interconnecting
cable and/or cable run in same
conduit as AC power lines See section 3.1
Lens or window clouding up Increase or decrease air purge
rate and/or investigate other
cause.
Improper grounding of cable shield
and/or IS 6 Advanced /
IGA 6 Advanced housing (or cooling
jacket)
IS 6 Advanced / IGA 6 Advanced
mounting not secure
Noisy readings (fast
fluctuations) Target moves more than 95% out of
field of view. Conveyor type
applications will also cause
fluctuations as targets move by the
field of view Application may require
Maximum to be stored. Apply
t
clear
settings. See section 4.5
Target may be changing temperature
quickly. (Thermocouples do not
respond as fast as the IS 6 Advanced /
IGA 6 Advanced)
Speed of response may be
slowed down
Apply t
90
settings. See section
4.4
Target may be reflecting nearby
objects that have fluctuating
temperatures
Loose connection in wiring
Electrical noise lead wires caused by
intense magnetic fields, improper
selection of inter-connecting cable
Cable run into in same conduit as AC
power lines
Flame or reflections of flame may be
entering the field of view
Extremely dense steam, smoke, thick
dust, personnel or moving machinery
intermittently blocking 95% of
optical path of IS 6 Advanced /
IGA 6 Advanced
Non-uniform emissivity of large
moving targets
Slower response speed is
required
