18INM MTL 130-0202 Rev 46.3 Trouble-shooting chartNOTEIt is assumed that the instrument and its installation have been checked for power supplyhealth, integrity and correctness of wiring and mechanical damage.If there is any doubt regarding interpretation of these instructions or the corrective actionsto be taken, contact your local MTL Gas sales office for clarification.KIM = Katharometer Identity Module (see photograph on next page).SYMPTOM POSSIBLE CAUSE TEST ACTIONInstrument appears to be“dead”.1. No power. 1. Check power onsupply terminal.1. Reinstate ifnecessary.2. Fuse blown 2. Check main fuse inAC power terminal block- see Figure 5.2. Replace if necessary,check supply voltage iscorrect. If fuse blowsagain see next symptom.3. Internal connectionfailure.3. Disassemble andcheck all connections.3. Replace KK650electronics –see section 7.9Instrument repeatedlyblows fuses.1. Wrong supplyvoltage.1. Check actual voltagesupply with that shownon the analyser datalabel.1. Contact yourlocal MTL Gassales office.2. Wrong value or typeof fuse.2. Check instrumentdata label for correctfuse.2. Replace asnecessary.Fault code between 1and 32 is displayed - seemanual sec 5.21. Unexpected gasapplied; e.g. highhydrogen contentmore than 60% overinstrument range.1. Pass air through theanalyser.1. Check to see if faultsstill exist, if not, checkcause 2 then 3.2. Sensorcontaminated.2. Clean sensor as persections 7.5/7.62. Check fault status,if OK recalibrateinstrument.3. Electronics failure. 3. Replace electronicsas per section 7.93. Recalibrateinstrument.Fault codes 64 to131072 will only occurduring calibration.1. Following a sensorchange1. Sensor and KIM arenot matched.1. Check that serialnumbers match – seeFig. 4 in manual forlocation of KIM1. Replace/exchangeas necessary.2. If these fault codesare displayed whenKIM and sensor areknown to match2. Calibration gasincorrect or not flowedfor sufficiently long.2. Check gas - replaceas necessary - and flowfor at least 10 minuetsat the correct flow rate- refer to calibrationsection in manual2. Try to recalibrateinstrument.3. Fault code remains 3. Memory corrupt 3. Reset factorysettings – see section7.10.2 and try torecalibrate.4. Fault code remains. 4. Sensorcontaminated.4. Clean sensor as persections 7.5/7.6 andrecalibrate.5. Fault code remains. 5. Electronics failure. 5. Replace electronicsassembly as persection 7.9
