2 Safety2.2 For Your Safety2.2.1 Explanation of the Symbols in the Safety NotesThe following symbols are used in these operating instructions as important safety notes forthe user. They appear within each chapter where the information is required. The safety notes,in particular the warnings, must always be observed and followed.DANGER!Identifies possible hazards to personnel, especially through electric power.WARNING!Indicates possible hazards to personnel caused by improper handling of system parts.CAUTION!Indicates risk to system parts or a possible adverse effect on functions.NOTICE!Contains important additional information for the user about the system or system parts, andoffers further tips.Appears in texts containing instructions for carrying out an action.In this context the user is urged to observe the statutory accident prevention measures duringall works, and to do everything in accordance with the situation to prevent damage to personsand property.7

2 Safety2.2.2 Proper Use - Conditions of Use2.2.3 Authorised UsersApplicationThe LT2 Lambda transmitter is an O 2 measuring instrument for the continuous measurementof O 2 concentration in non-combustible gases in the super-stoichiometric domain, in conjunctionwith the LT2 Lambda probe.If the system is to be used in some other way, and if the instrument's functionality in this applicationcannot be unambiguously assessed, the manufacturer should be contacted in advance.PrerequisitesIt is assumed that facility planning, assembly, installation, commissioning, maintenance andservice works are carried out by sufficiently trained personnel, and these works are supervisedby qualified specialists.Correct handlingSpecial attention must be paid to the following:– The application must conform to the technical data and the specifications regarding authoriseduse, assembly, connection, environmental and operational conditions (derivedfrom the job documentation, the instrument's user information, rating plates etc), and tothe documentation supplied.– The local regulations and facility-specific and technical hazards must be noted and followed.– All steps necessary to protect the equipment, e.g. during transport, storage, maintenanceand inspection, should be carried out.Qualified personnelThose responsible for safety must always ensure that– only qualified personnel carry out work on system parts. Qualified personnel have been authorised by those responsible for maintaining the safetyof employees and that of the facility, to perform such activities as a result of their training,experience or familiarity with the relevant Standards, regulations, accident preventionmeasures and local conditions. The important factor is that such personnel are able toidentify and prevent possible hazards in good time.Specialist personnel are those meeting DIN VDE 0105 or IEC 364, or directly comparableStandards such as DIN 0832.– these personnel have the supplied operating instructions and the associated, job-relateddocumentation available to them during all works, and observe these documents in orderto avoid hazards and damage.8

2 SafetyUser groupsTwo user groups are assumed to handle the LT2 Lambda transmitter:a Operators, the customer's installers, measurement/control/electric/electronic technicians- have elementary knowledge of the instrument.b Service technicians of LAMTEC or their OEM customers, or the customer's trained personnel:qualified technicians/engineers - have very good knowledge of the instrument.c Operating personnel with basic knowledge access level "OPERATION SERVICE" - without password2.2.4 Safety Facilities / Safety MeasuresHazards from electric equipmentThe LT2’s system parts are items of equipment designed to be used in industrial high-currentfacilities. When working on parts connected to the supply or carrying supply voltage, disconnectfrom the supply and ensure zero voltage. Re-install all machine guards before reconnectingto the supply.Damage to health or to property may result from improper use or incorrect handling. To preventdamage, observe the appropriate safety notes.Preventive measures for improving operating safetyWhere the LT2 is used as a sensor in conjunction with regulating or control systems, it is theoperator's responsibility to ensure that LT2 failure or faults cannot lead to dangerous situationsor those that cause unacceptable damage.In order to prevent faults, which in turn could cause direct or indirect damage to personnel orto property, the operator must ensure that– the appointed maintenance personnel can be notified at any time and as soon as possible,the maintenance personnel are trained to respond correctly to LT2 faults and associatedoperational faults– in the event of doubt, the affected equipment is immediately switched off– switching off does not lead to direct consequential faultsCAUTION!In risk of a shortfall below the dew point in the gas channel, you must heat the gas extractiondevice (MEV) and eventually the preliminary filter electrically.Prevention of consequential damageTo prevent consequential damage in the event of instrument faults, which in turn could causedirect or indirect damage to personnel or property, ensure that qualified personnel assess thefaults and initiate appropriate steps.2.2.5 Protection Against Emissions from Gas-carrying ChannelsThe LT2 Lambda transmitter is directly attached to the gas-carrying channel, via the probe installationfitting (SEA). If the LT2 Lambda probe or the SEA installation fitting are dismantled;then depending on the facility and particularly in the event of excess pressure, aggressive and/or hot gas may be emitted from the channel and cause severe health damage to unprotectedoperatives, unless suitable protective measures have previously been put into place.9

2 SafetyWARNING!In the event of excess pressure and temperatures above 200°C in the gas channel, dismantlingthe LT2 Lambda probe or the installation fitting lead to the emission of gases.- Switch off the facility before opening. If this is not possible, wear protective clothing and aprotective mask.- Put up appropriate warning signs near the installation site.- Close the aperture at once. You can get adequate sealing flanges, (blind flang) as an accessory.2.2.6 Important Notes on Shutdown/Return to ServiceThe LT2 Lambda transmitter and the LS2 Lambda probe form a high quality electronic measurementsystem. Treat them with care at all times, including during shutdown, transport andstorage.ShutdownCAUTION!Do not switch the LT2 Lambda transmitter off as long as the LS2 Lambda probe is mounted;including when the relevant facility has been shut down. Residual gases cause corrosion andmay damage system parts.Do not store the instruments outdoors without protection!Always store in a dry place, if possible in the original packaging.When dismantling, protect cable ends and plugs against corrosion and dirt. Corroded plugsmay cause malfunction.If possible, transport in the original packaging.Return to serviceAccording to chapter 6 Commissioning / Shutdown.2.2.7 Environmental Protection, Waste DisposalThe LT2 Lambda transmitter's construction is also based on environmental considerations.The modules can easily be separated and sorted into distinct types, and recycled accordingly.10

DLT2002, orvia a PC in conjunction with the (optional) service and diagnostic software, or via an externaloperating unit using an RS 422 interface (in preparation). The LT2 itself has only limited operatingcapabilities, which however allow it to initiate or to display on the LT2 all the functionsnecessary for operation, maintenance and servicing, including directly.NOTICE!The display and operating elements are not freely accessible on the LT2 - panel installation.For this reason the LT2 - panel installation is generally supplied only with a 657 R 08 31 displayand operating unit.1 Display of operating mode2 Warning /Fault display3 Maintenance switch4 Multifunction key6.2.2 Monitor OutputThe monitor output [terminals 31 (-), 32 (+)] make it possible to connect (e.g.) a multimeter.You can interrogate the following values on site via the LT2's monitor output:– O 2 -measured value– Probe voltage [U S ]– The measuring cell's AC internal resistance [R I ]DIP switch processor cardSW 1 SW 2 Monitor output functionoff off O 2 -measured value 0...2.5 V = 0...25 Vol.% O 2on off Probe voltage 0...2.5 V = 0...250 mVoff on Cell internal resistance 0...2.5 = 0...250 Input resistance of the connected meter greater than 10 k.32

6 Commissioning / Shutdown6.3 Measurement Start-upWARNING!When installing the probe and during later operation, ensure that the probe does not into contactwith oils, grease or boiler cleaning materials.This applies not just to the cell, but also the connector region!The thread and the clamping ring should be treated with mounting paste type 655 R 1090against seizing.Poisoned or contaminated probes can be identified by an air voltage of -20…-30 mV. In addition,the probe must always be in operation when installed. This avoids the precipitation ofmoisture on the measuring cell, which in certain cases could lead to erroneous measurementsand to the probe's destruction!• Connect the probe but do not install itSwitch to Maintenance either via the display and operating unit in menu "diag” or with themaintenance switch S1Maintenance (orange) LED 1NOTICE!The maintenance switch always has priority.– Maintenance mode active– Normal operation– Maintenance mode off– Maintenance mode on• Switch on voltage• LED 1 shows "Maintenance”• Probe warms up• Cold-start is shownLED 6 "Operation” ONLED 5 "Measurement OFFNOTICE!During cold start the display and operating unit or the monitor output shows/output the cell’sinner resistance R I .The measurement function is operational after 10 minutes.TMeasurement is shownLED 6 "Operation” lights upLED 5 "Measurement " lights upNOTICE!The cold-start delay can be activated from the display and operating unit → "cal” key.

6 Commissioning / ShutdownNOTICE!Reading off probe voltage:either via display and operating unit (if available) → press "meas”, choose probe voltage U S .After a heating-up phase of 10 minutes, probe voltage stabilises at avalue between -5 and -15 mV and the AC internal resistance at a valuebelow 100Multifunction key T 26.3.1 Install the Probe in the PIF and Align the GED, See Illustration:1 welded2 Flue gas3 Gas extraction device(GED) type 655 R 1001...10044 Probe installation fitting(PIF) type 655 R 10105 Rating plateFig. 6-1 Probe installation• Start up combustion• Measured value plausible?Check if necessary via comparative measurementWARNING!Almost all extractive O 2 -meters measure "dry”, in contrast to the in-situ ZrO 2 -meters; i.e. moistureis extracted from the flue gas through a purification process (cooler) or a chemical absorber(silica gel). This reduces the volume of the measured gas, and thus the proportion of O 2increases. This fact must be taken into account during comparative measurement. A diagramfor converting wet into dry measurements can be found in chapter 11.4 Wet/Dry MeasurementDeviations, Conversion Table• If large deviations are present, it is possible to compensate for the values obtained via– the display and operating unit, under "cal”– the service and diagnostic software– as follows, using the multifunction key:Measure the O 2 value at the monitor output or analogue output. Start calibration with the multifunctionkey. LED 5 should flash rapidlyBriefly pressing the multifunction key increases the output O 2 value by 0.1%Pressing for a longer time terminates the modification.WARNING!Calibration should only be carried out if it was previously ascertained that the comparison instrumentis measuring correctly (e.g. by using test gases).35

6 Commissioning / ShutdownIn any event, offset calibration should previously have been carried out under operational(warm) conditions. It is necessary to ensure that ambient air is present at the measurementsite. If this is not ensured, the probe must be dismantled again for the offset6.4 Setting up Service Warnings6.5 ShutdownService warnings 1 and 2 are designed to draw attention to regular servicing. The service warnings can be freely defined by the operator, e.g.Service warning 1 check probeService warning 2 dismantle and clean probeThe appropriate cycle times can be specified via the parameters 1260 and 1261 in the range1 to 65535 hours.In order to be sure to avoid damaging the LS2Lambda probe's ZrO 2 measuring element, theprobe must be dismantled before the system is shut down or immediately after the supply voltageis switched off.WARNING!Dismantle the Lambda probe before shutting down the measurement system.Caution: hot!NOTICE!Once dismantled, the LS2 Lambda probe can be stored indefinitely. The zirconium element isonly consumed during operation (measuring cell at operating temperature). This also applieswhere a probe has already been used previously.36

However, thisslows down the display in terms of reaching an end state.NOTICE!Large damping simultaneously leads to an artificial slowing down of the measurement signal.7.2.2 Operational Failure, Switching On and OffIn the event of long interruptions during operation, lasting for longer than approx. 3 months, itis recommended to switch off the measuring system. The probe should be dismantled to avoiddamage.We recommend: You should definitely continue with the measurement in the case of shortservice interruption.38

7 Operation7.2.3 Liquid PurificationYou are allowed to perform a liquid purification of the boiler, when you dismantle the probebeforehand. If you perform a liquid purification to an installed probe, this could damage theprobe. An error free operation is then no longer possibleCAUTION!For the liquid purification, the probe must be dismantled by all means. A liquid purification ofan installed probe will damage the probe.39

8 Service and Maintenance8 Service and MaintenanceIf you want to proceed a liquid purification you must note the following:You may only proceed a liquid purification, if you have dismounted the probe first. If you proceedthe liquid purification without dismounting the probe, this will damage the probe. Theprobe will not function properly after that.CAUTION!You must dismount the probe before liquid purification anyway. Liquid purification without dismountingthe probe will damage the probe.8.1 Checking the O2 Probe8.1.1 Checking the Air VoltageMultifunction key T 2• Switch off the facility• Pre-ventilate, until no more flue gas is present at the measurementsite (approx. 1 minute).• Turn off the pre-ventilation.• Carry out offset calibration either via• the (optional) display and operating unit via "cal” - menu-driven• the (optional) service and diagnostic software• T2 multifunction keyNOTICE!FunctionsToggle the displayed warning/faultReset the displayed warning/faultQuick start of the measuring gas pump - abort ofthe cold startTrigger an offset calibrationHandling of the KeysPress shortlyPress for longer than 3 sec.*Press for longer than 3sec.**Press key for longer than 3 sec.during measurement*** Some warnings and faults cannot be reset if the error is still present or the routine isstill running.**If at least one warning or fault is still present, the key must be pressed for longer than6 seconds.If probe voltage is outside the permissible range, the warning "Offset calibration to air invalid”is output.• Read out probe voltage at LT2either via– the display and operating unit (option)– the service and diagnostic software (option)– measure probe voltage with a multimeter; Connect a digital voltmeter in parallel to the probe at terminal 33 (-) and 34 (+). Compare the measured voltage with the displayed voltage (US).• Valid range: - 0mV … -20 mV• If the probe’s voltage is above/below this range → replace probe40

8 Service and MaintenanceCAUTION!Don’t forget!You must perform a new offset-calibration with ambient air and enter the probe’s new temperaturevalue after replacing the probe.Limit value 4 is set at the factory: An automatic check of the probe is possible at downtime andat pre-ventilation of the plant. No response of the limit values!Limit value 4 →An intact probe doesn’t cause fault no. 1. If fault no. 1 " probe voltage < -20mV " occur, youmust reset it manually.NOTICE!After the loss of the power supply (and therefore the heating of the probe), the probe voltagemay decrease for a moment -20mV in the heating period.We recomend: Retain the factory-set limit value 4 for safety reasons.If the facility cannot be switched off, the probe must be dismantled for examination.8.1.2 Checking by Counter-measurement5 mV shortfall, automatic resetDelay time of the trigger 3 seconds-20mV shortfall is monitored by fault no. 1Precise checking of the measurements is only possible through counter measurement with a2nd probe, or by comparing the values measured after probe replacement.NOTICE!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 toinstruments that extract moisture via a chemical compound. The LS2 Lambda probe measureswet. The difference between wet and dry measurements can be obtained from the diagramin the Appendix (see page 81 11.4 Wet/Dry Measurement Deviations, ConversionTable).• If large deviations are present, it is possible to compensate for the values obtained via– the display and operating unit, under "cal”CAUTION!At calibration of the measurement value with the display and operating unit → cal , you mustconfirm the new calibration value with "ENTER" or "OK". If you don’t do so, the menu will bequit automatically after 15 sec. and the new calibration value will be.• the service and diagnostic software• as follows, using the multifunction key:Measure the O 2 value at the monitor output or analogue output.Start calibration with the multifunction key.LED 5 should flash rapidly (see page 44 6.2.3 Internal Display and Operating Elements).Briefly pressing the multifunction key increases the output O 2 value by 0.1%(pressing for a longer period reduces the O 2 value; 0.1% in 2 seconds).If no operation follows within 15 seconds, the test gas calibration is terminated.41

8 Service and MaintenanceCAUTION!Which instrument measures correctly?Compensation should only be carried out if it was previously ascertained, e.g. by using testgases, that the comparison instrument is measuring correctly.8.2 Checking the LT28.2.1 Checking the LT2's Measuring InputConnect a digital voltmeter between terminals 33 (-) and 34 (+), in parallel to the probe. Comparethe measured voltage with the probe voltage displayed (U S ).Range: -20 mV … +300 mV.If the difference is less than 1 mV, the LT2 is operating correctly.If the difference exceeds 1 mV, repeat the above step with another digital voltmeter.CAUTION!Check the accuracy of the digital voltmeter used.If the difference persists → exchange the instrument.8.2.2 Checking the Probe's Internal Resistance Measurement8.3 ServicingOnly possible with an LS2 probe simulator, type 655 R 1030.Connect the probe simulator between terminals 33 (-) and 34 (+).With a potentiometer, set an internal resistance < 200Use a voltmeter as follows to check the internal resistance:Measure AC voltage between terminals 33 (-) and 34 (+).The displayed value in mV corresponds to about one half of the probe's internal resistance.If R > 200 , the following warning is output after 10 seconds:"LS2 internal resistance too high”.If R > 300 , the following fault message is output:"Probe wire break / probe faulty”.Example: 150 75 mV.8.3.1 ConsumableCheck the measurement system on a monthly, quarterly or semi-annual basis, depending onthe application.LS2 Lambda probe Mean lifetime 2-3 years (depending on fuel).42

9 Faults / Warnings9.3.1 Faults - Causes and SolutionsProbe voltage too low• Probe + / - reversed probe connection terminal 33-34 change• Probe poisoned replaceNOTICE!Probe voltage to air 0 to–20 mVDefective LS2 Probe HeatingNOTICE!In 99% of cases, the LS2Lambda probe was not connected properly during operation (theprobe heating plug had been pulled out). Reset the fault, either via the multifunction key or viathe display and operating unit etc. A fault is only present if the fault cannot be reset.Possible causes:• Check fuse F 5,see chapter 11.3.4 LT2 Power Electronic Type 657 R 1882Check the probe's heater. In an intact heater, ca.10 (9 to 11) could be measured betweenterminal 35 - 36. If not (R ) heater faulty - replace probe. If intact, check the supply voltage: the probe'sheater must be supplied with approx. 13 V DC, cyclically reversed; if not, check the wiring andthe terminals and tighten if necessary.NOTICE!The probe is heated with direct current at approx. 13 V, cyclically reversed. Hence the use ofa multimeter to measure it is somewhat difficult.NOTICE!The current heating data can be read out from operating parameters 41/42/43.Broken wire Probe / Defective ProbeThis message is output if the AC internal resistance (Ri ) or the ZrO 2 cell exceeds the permissiblelimit of 300. Before or after this message you normally will get the warning "Inner resistanceLS2 too high".Possible reasons:• The probe is disconnected (measuring signal on terminals 33 to 34)• Loose connection check the terminals, retighten• Probe too cold, possibly enhance the heating power gradually (0,5W)• Check wiring, if OK replace probeNo Probe DynamicsNo probe dynamic detected. Check the probe.45
