Sensor temp. comp.
The clamp-on sensor temperature compensa-
tion has failed, because measurement of tem-
perature failed. This could be due to errors in
attached cabling or measurement equipment,
defect sensor frontend electronics or configura-
tion errors on channels 3, 4, 5 or 6. Investigate
DSL error codes to determine precise root
cause and required actions. For processes with
a constant temperature, the sensor tempera-
ture compensation can alternatively be based
on a fixed user specified process temperature.
28
Configuration 1
An invalid configuration was detected. Investi-
gate detailed diagnostics to determine precise
root cause. Investigate DSL error codes to
determine which settings are invalid. The setup
parameters must be changed via the local
display menu or via an external configuration
tool.
32
Auxiliary input
The auxiliary measurement on CH5 or CH6
has failed. This could be due to errors in at-
tached cabling or measurement equipment,
defect sensor frontend electronics or configura-
tion errors on channels 3, 4, 5 or 6. Investigate
DSL error codes to determine which settings
are invalid.
34
Invalid flow meas.
Signal was lost on 1 or more paths causing the
measurement to stop or become untrustworthy.
Check if device is configured properly, Investi-
gate DSL error codes to determine precise root
cause.
35
Failure on CH5 or CH6
Configuration of channel 5 or 6 failed. The
electronics may be defect or the sensors con-
nected to channel 5 or 6 are defect or installed
incorrectly. If alarm still exists, call service
personnel. It may be necessary to replace the
DSL electronics.
36
Configuration 2
An invalid configuration was detected with
impact on the measurement accuracy. Investi-
gate DSL error codes to determine which set-
tings are invalid. The setup parameters must
be changed via the local display menu or via
an external configuration tool.
