Faults/Warnings
9.3.1.4 No Probe Dynamics
No probe dynamic detected. Check the probe.
Testing is shut off on delivery.
Activate testing in parameter group 1330 to 1334.
The testing checks, if the measuring value changes more than the parameter set threshold
value during a specified time.
Only valid in combination with an integrated O
9.3.1.5 Fault Analogue Output
Check the parameters of the analogue outputs.

Check the analogue outputs on the processor electronic and replace them if necessary. An
analogue output might be activated, but is not assembled˜
(see chapter11.4.3 Fuses)
The parameters can only be viewed via the display and control unit or remote display software.
Without these options, the computer electronics must be sent in.

During counter measurement, check whether the instrument being used measures wet or dry.
Those with an advance gas cooler are always used for dry measurement. This also applies to
instruments that extract moisture via a chemical compound. The LS2 Lambda Probe meas-
ures wet. The difference between wet and dry measurements can be obtained from the dia-
gram in the Appendix, see chapter 11.5 Wet/Dry Measurement Deviations, Conversion Table
NOTICE
Parameter 530 ... 539 analogue output 1
Parameter 540 ... 549 analogue output 2
Parameter 550 ... 559 analogue output 3
Parameter 560 ... 569 analogue output 4
Check assembly.
Has the relationship between wet/dry measurement been taken into account?
see chapter 11.5 Wet/Dry Measurement Deviations, Conversion Table
Check LT2 and probe, see chapter 8.2 Checking the LT2
Commission the new probe as described in chapter 6 Commissioning/Decommissioning
Measuring value too high? Secondary air, check sealing and hose connections if they are
tight.
