Page 9: Safety Equipment/Safety Measures
To avoid damage, always observe the respective security notices. Preventive measures for improving operating safety If the LT3 is used in conjunction with control and monitoring technology, the operator must en- sure that any breakdown or failure of the LT3 device does not cause inadmissible damage or dangerous operating states. - Page 10 General Safety Instructions NOTICE Do not switch off the Lambda Transmitter LT3 as long as the LS2 Lambda Probe is mounted. Not even if the associated plant has been brought to a standstill. Residual gases will cause corrosion and could damage the probe.

Page 21: Maintenance
Maintenance Maintenance As a result of extensive self-diagnosis, the measuring system is essentially maintenance-free. Maintenance is restricted to the calibration and the cleaning of dust or other deposits; as well as the cyclic replacement of the ZrO measuring element. Probe Testing and Calibration The checking / calibration has to be built (advantageously installed) in at normal operating temperature and carried out under operating conditions. - Page 22 Maintenance In MEASURED VALUES and PROBE DATA, select: Display of the O measured values, Display of the R internal probe resistances Display of the current fuel selection The O probe voltage U-O stabilises to val- ues between +10 ... -20 mV.

Page 55: Appendix
Wet/Dry Measurement Deviations, Conversion Table NOTICE The LT3 carries out measurements directly in the humid flue gases (wet measurement). When extractive devices are used, flue gases are removed and prepared. Dry measurements are normally used here, since the humidity has been extracted from the flue gas. -
