Malfunctions
The following malfunctions can be removed under circumstances at site.
Message Significance Possible cause Action
LED monitor overflow Overdriving of the
monitor channel when
scaling
Incorrect alignment of the
optical axes of sender/receiver
unit and reflector
b Check/correct alignment.
b Repeat scaling.
Q1-4 overflow Group signal of
quadrant measurement
too high
● Measuring system not yet
scaled
● Changed alignment of opti-
cal axes
● Reduced active measuring
path
b Scale measuring system.
b Check/correct alignment.
b Contact SICK service.
Set reference Scaling not possible Measurement or monitor signal
too low (contamination,
incorrect alignment)
b Check/correct alignment.
b Clean the optical surfaces ( →
p. 92, §5.2).
Overflow check point Measurement signal at
check point outside the
valid range
b Repeat scaling.
b Clean the optical surfaces ( →
p. 92, §5.2).
b Contact SICK service.
Contamination (not for
DUSTHUNTER T50)
Current contamination
value is higher than the
permitted limit value (
→
p. 108, §7.1)
● Deposits on the optical sur-
faces
● Unclean purge air
b Clean the optical surfaces ( →
p. 92, §5.2).
b Check purge air filter and
replace, if required (
→ p. 97,
§5.3).
b Contact SICK service.
LED span Deviation of control
value > ± 2%
● Deposits on the optical sur-
faces
● Vibrations
b Clean the optical surfaces ( →
p. 92, §5.2).
b Contact SICK service.
