This featureis effective when an O2 sensor is notbuilt in.(An input signal triggers measured concentrationindication and O2 conversion.)Relay contact output:1a contact (250V AC/2A, resistive load)Instrument error, calibration error,range discrimination, auto calibrationstatus and maintenance status, pumpON/OFF, peak alarm.1c contact (250V AC/2A, resistive load)Upper/lower alarm contact output.(for each channel)Power disconnection alarm.* All relay contacts are isolated mutuallyand from the internal circuit.Contact input: No-voltage contact (ON/0V, OFF/5VDC, 5mA flowing at ON)Remote range changeover, auto calibrationremote start, remote holding,average value resetting, pump ON/OFFIsolated from the internal circuit withphotocoupler.

Indication values willnot be held.Remote range changeover:Measuring range can be changed accordingto an external signal when remoterange changeover input is received.Changeover is effective only when remoterange setting is turned on. In thiscase, measuring range cannot be changedmanually.When the contact input terminals for eachcomponent are short-circuited, the firstrange is selected, and it is changed overto the second range when the terminalsare open.Range identification signal:The present measuring range is identifiedby a contact signal.The contact output terminals for eachcomponent are short-circuited when thefirst range is selected, and when the secondrange is selected, the terminals areopen.Auto calibration:Auto calibration is carried out periodicallyat the preset cycle.When a standard gas cylinder for calibrationand a solenoid valve for opening/closingthe gas flow line are prepared externallyby the customer, calibration will becarried out with the solenoid valve drivecontacts for zero calibration and each spancalibration turned on/off sequentially atthe set auto calibration timing.Auto calibration cycle setting:Auto calibration cycle is set.Setting is variable within 1 to 99 hours(in increments of 1 hour) or 1 to 40 days(in increments of 1 day).Gas flow time setting:The time for flowing each calibration gasin auto calibration is set.Settable within 60 to 599 seconds (in incrementsof 1 second)

Auto calibration remote start:Auto calibration is carried out only onceaccording to an external input signal. Calibrationsequence is settable in the sameway as the general auto calibration.Auto calibration is started by opening theauto calibration remote start input terminalsafter short-circuiting for 1.5 secondsor longer.Auto zero calibration:Auto zero calibration is carried out periodicallyat the preset cycle.This cycle is independent on "Autocalibradion" cycle.When zero calibration gas and solenoidvalve for opening/closing the calibrationgas flow line are prepared externally bythe customer, zero calibration will becarried out with the solenoid valve drivecontact for zero calibration turned on/offat the set auto zero calibration timing.Auto zero calibration cycle setting:Auto zero calibration cycle is set.Setting is variable within 1 to 99 hours(in increments of 1 hour) or Setting isvariable within 1 to 40 days (in incrementsof 1 day)Gas flow time setting:The timing for flowing zero gas in autozero calibration is set.Settable 60 to 599 seconds (in incrementsof 1 second)Upper/lower limit alarm:Alarm contact output turns on whenmeasurement value reach to the presetupper or lower limit alarm value.Contacts close when the instantaneousvalue of each component becomes largerthan the upper alarm limit value or smallerthan the lower alarm limit value.Instrument error contact output:Contacts close at occurrence of analyzererror No. 1, 3 or 10.Calibration error contact output:Contacts close at occurrence of manualor auto calibration error (any of errors No.4 to 9).Auto calibration status and maintenance status contactoutputs: Contacts close during auto calibration andduring input of the remote hold signal.Pump ON/OFF contact output:During measurement, this contact close.While calibration gas is flowing, this contactopen. This contact is connected inpower supply of pump, and stop thesample gas while calibration gas flowing.Optional FunctionsO2 correction: Conversion of measured NO, SO2 and COgas concentrations into values at standardO2 concentration21–OnCorrection formula: C = –––––––– x Cs21–OsC : Sample gas concentration after O2correctionCs : Measured concentration of samplegasOs : Measured O2 concentrationOn: Standard O2 concentration (valuechangeable by setting)*The upper limit value of the fractionalpart in this calculation is 4.The result of calculation is indicated andoutput in an analog output signal.Average value after O2 correction and O2 average valuecalculation: The result of O2 correction or instantaneousO2 value can be outputted as anaverage value in the determined periodof time.Used for averaging is the moving averagemethod in which sampling is carriedout at intervals of 30 seconds.(Output is updated every 30 seconds. Itis the average value in the determinedperiod of time just before the latest updating.)Averaging time is settable within 1 to 59minutes (in increments of 1 minute) or 1to 4 hours (in increments of 1 hour).Average value resetting:The above-mentioned output of averagevalue is started from the initial state byopening the average value resetting inputterminals after short-circuiting for 1.5seconds or longer.Output is reset by short-circuiting andrestarted by opening.CO concentration peak count alarm:(added only for CO/O2 measurement)Alarm output turns on according to thepreset concentration and count.Whenever the instantaneous value of COexceeds the preset concentration value,count increments. If the count exceedsthe preset value in one hour, the alarmcontacts close.Communication function:RS-232C (9pins D-sub)Half-duplex bit serialStart-stop synchronizationModbus TM protcolContents: Read/Wright parametersRead measurement concentrationand instrument statusRemark: When connecting via RS-485interface, a RS-232C RS-485 converter should be used.PerformanceRepeatability : ± 0.5% of full scaleLinearity : ± 1% of full scaleZero drift : ± 2% of full scale/weekSpan drift : ± 2% of full scale/weekResponse time :(for 90% FS response)Within 60 seconds including replacementtime of sample gas (when gas flow rateis 0.5L / min)3

ZKJExclusive Zirconia O2 Sensor(to be purchased separately)For O 2correction, the gas analyzer ZKJ can accept linealized0 to 1V DC signal coming from analyzer calibrated 0 to 25%O 2full scale. If the analyzer is not available, Fuji can supplyexclusive Zirconia O 2sensor Model ZFK.Measuring method:Zirconia systemMeasurable component and measuring range:Measurable component Minimum range Maximum rangeO2 Oxygen 0 to 5vol% 0 to 25vol%Repeatability: Within ± 0.5% of full scaleLinearity: Within ± 1% of full scaleZero drift: Within ± 1% of full scale/weekSpan drift: Within ± 2% of full scale/weekResponse time: Approx. 20 seconds (for 90% response)Measured gas flow rate:0.5 ± 0.25L / minRemark: The Zirconia system, due to its principle,may produce a measuring error due torelative concentration versus the combustibleO 2gas concentration. Also, acorrosive gas (SO 2of 250 ppm or more,etc.) may affect the life of the sensor.OUTLINE DIAGRAM (Unit:mm)170Gas inlet/outlet size:Rc 1 /4 or NPT 1 /4Power supply: 90 to 126V AC or 200 to 240V AC,50/60HzEnclosure: Steel casing, for indoor applicationIndication: Temperature indication (LED)Temperature alarm output:Contact output 1a contact,Contact capacity 220V, 1A AC (resistiveload)Outer dimensions (H x W x D):140 x 170 x 190mmMass {weight}: Approx. 3kgFinish color: Munsell 5Y 7/1CODE SYMBOLS1 2 3 4 5 6 7 8Z F K 7 Y Y7 Y Y134 -9 10 11 12 1318Y 0 Y YDescriptionMeasuring methodZirconia methodPower supply90 to 126V AC 50/60Hz200 to 240V AC 50/60HzGas inletRc 1 /4NPT 1 /4152OXYGEN ANALYZERTEMP8001401317-M4110POWER FUSE3A1 2 3 4 5 6 7OFF+ -AC E OUT ALM517 Gas inlet 172.3 Gas outletEXTERNAL CONNECTION DIAGRAM1 2 3 4 5 6 7AC power50/60Hz+ -supply E Outputto ZKJTemperaturealarm outputThe product conforms to the requirements of theElectromagnetic compatibility Directive 89/336/EEC asdetailed within the technical construction file numberTN512919.
