SENSOR LOCATION
Combustiblegassensors are used to detect a varietyofgasesorvapors. The propersensor
location will dependon what type ofgasisexpected. Forgasesthat arelighterthan air, suchas
methane, sensors shouldbe located nearthe ceiling. Forgasesthat areheavierthan air, suchas
butane, sensors should bemounted nearthe floor. Ifthe gasorvaporhasa densitynearthatofair,
locatethesensorabout5 feet off the floorin enclosed areas. Gassensors mounted outdoors shouldbe
located nearanticipated leaksources(valves, flanges,compressors, etc.)and thelocation will dependon
normalwind patternsand anticipated employee activityareas.
The following are a fewcommon combustiblegases,along with theirrelativedensity(air=1.00).
Densitiesless thanone indicate gasesthat arelighterthan airwhile thosewith densitiesgreaterthan one
are heavierthan air.Combustiblevapors frommost solvents, suchan Benzene, n-Hexane, Methanol,
Ethanol, and MEK, are heavierthan airandwilltend to accumulate nearthe floorin enclosed spaceswith
littleairmovement.

Hydrogen0.07
Ammonia0.60
INTERFERENCES
Combustiblegassensors containtwo heated elements.One oftheseelementsisactive, and will
allowcombustiblegasesorvapors to burnon itscatalyticsurface. The otheris passive, and doesnot
reactto gases.Thesetwo elementsformtwolegsofaWheatstone bridge measuringcircuit. When
combustiblegascontactsthe sensor,the activeelement burnsthisgasand the temperatureofthis
element increases,changingitsresistance.The transmittermeasurestheimbalanceinthe bridgecircuit
and transmitsthe data to the receiverfordisplayand alarming purposes.
Combustiblesensors areadverselyaffected byafewcompoundsthat maybepresent inagiven
application.Probablythe worstofthesearesiliconevapors fromsilicon basedlubricantsorsealants.
High siliconvaporconcentrationscan causecomplete loss ofsensitivityinaslittleasafewhours.These
sensors shouldnotbeusedwheresiliconvapors arenormallypresent,and sensors shouldbe protected
fromthese vapors ifsuch compoundsare in usetemporarily.
Leadcompoundsandhigh levelsofhydrogen sulfide can alsocausedegradationofcombustible
sensors.Whilelead vaporsarenot commonlyencountered, theycanalsocausecomplete sensorfailure
ifencountered. Hydrogensulfide willcausereducedsensitivityoverthefirstfew weeksofexposure,but
thenwilllevelout.The effectofhydrogensulfidecannormallybe compensatedforbyre-calibrationafter
the first fewweeksofuse.

OPERATION
Onceinstallationiscomplete, the C12-17 combustiblegastransmitterisreadyforoperation.
Afterverifyingthatelectricalconnectionshavebeenmade properly,put the transmitterinto operationby
simplyapplying DC power.Assoon aspowerisapplied, the unitwill beginto stabilize. Oncestabilized,
alarmsysteminhibitcan be turnedoff, and the systemwillbe in normaloperation.
Note:Theoutput of thetransmitterwill go to ahighvaluewhenpoweris firstapplied.Alarm
devices shouldbeinhibitedatthis timesothatalarmsystemsarenot activated.The
output will stabilize at4 mAwithinabout 10 minutes.
CALIBRATION
Combustiblegassensor/transmitters arefactorycalibrated forastandardrangeof0-100%LEL
Methane, usingmethane gasasthe calibration standard. However,combustiblegassensors do not
respond exactlythesameto everycombustiblegas,and the percent ofeachgasthat represents100%
LELalsodiffers foreachgas.While methane gasstandardscan alwaysbe usedforcalibration, the value
that the transmitterisadjusted towillvarydependingonwhat type ofgasthesystemismeant to detect.
Calibrationofa combustible gassensor/transmitterrequiresa digitalvoltmeter(DVM),a sourceof
calibration gas,andacalibrationadapterforthe sensor.Calibrationgascan beobtainedinconvenient
disposablecylinders fromspecialtygassuppliers suchasScott SpecialtyGases,Alphagaz,orMatheson
GasProducts.Completecalibration kitsmayalsobe purchased fromATI. Thesekitscontainone
methane gasstandard(1%methane inair,whichis20%LEL)inadisposablecylinder,abottleofzero
air, a cylinderregulator, and a calibration adapter.

TRANSMITTER SPAN
The span settingforacombustiblegassensor/transmitterwill depend onthegasorvaporfor
whichthe unitwill be mainlyused.Tocalibrate the systemforapplicationswheremethane inthemain
combustibleto be expected, connecttubing fromyourspan gascylinder(1%Methane)to thecalibration
adapterinlet. Turnon the gasflowand adjustto approximately500 cc/min. (ATIcalibration kitscontain
fixed flow regulators thatautomaticallyprovide500 cc/min. flow).The reading on theDVMattached to
the transmittertestpointswillimmediatelystartto increase. Allowthegasto flowto the sensorfor2-3
minutesand observethe reading on theDVM. The reading shouldbe relativelystable±0.5 mv.Usethe
span potentiometerto adjustthe DVMto72 mv.Thisadjustment assumesthe useof1%methane gas
standards,whicharethe equivalentof20%LEL. Ifusing anothermethaneconcentration, calculatethe
voltage settingasfollows: (v/o =Volume Percent)
V =40 mV+[160 mVX (Span GasConcentration in V/O÷5 V/O)]
Asan example, ifyourspan gascylinderismarked with aconcentrationof2.5%Methane, the
calculationwould be:
V =40 mV+[160mV X (2.5 V/O ÷5 V/O)] =120 mV
When the span hasbeen set, turnoff the span gasflowandremove thecalibration adapterfrom
the sensor.Place the lid backon the transmitterenclosure and tighten the coverto insure the enclosure
remainswatertight. Ifthe ATI receiveralarmrelayswere inhibited priorto calibration, press the A/R
switch to return the systemto normaloperation.
TRANSMITTER FAULTINDICATION
The C12-17combustiblegastransmitterisdesignedtodetectcertainfaultconditionsinthe
sensorand transmitterandto indicate the faultconditionsbydriving the 4-20mAoutputto below2mA.
Receiving instrumentsthatcan identifythisconditionandprovideavisualindicationofthefaultwill
provideaddedsecurityforyourgasdetection system.When the C12 signalisused asan input toaPLC
orcomputersystem,the systemshouldbeprogrammed to recognizea2mAoutput asafaultcondition
forthe transmitter.
The below 2 mAfault condition will be generated underthe following conditions:
One ofthe sensorleadsisnot connected at the terminalblock.

CALIBRATION FOR OTHER COMBUSTIBLEGASES
Aspreviouslymentioned,acombustiblegassensorhasaslightlydifferent responsetoeach
combustiblegasorvapor.Inaddition,theLEL(LowerExplosiveLimit)representsdifferent percent
concentrationsfordifferent gases.Forinstance, the LELformethane is5%byvolumewhilethe LELfor
butane is1.9%byvolume. Becauseofthesefactors,acombustibletransmittermustbe adjusted
differentlyifthe systemismeant to detect a gasorvaporotherthan methane.
A1%methanegasstandardmaystill be used forcalibration ofcombustibletransmitters when
used forothergases.However,the voltagethat youset at the transmittertestpoint will bedifferent for

SENSOR RESPONSE TEST
Whilezeroand span adjustmentsarerequiredonlyperiodically,gassensors shouldbechecked
regularlyforproperresponse. The responsecheckcan be done quicklybysimplyaiming the outlet tube
fromthe span gascylinderat the faceofthe sensorand turning on thegasflowfor10-20 seconds.The
sensorshould begin to respond within 5 seconds.
Toobservetheresponseatthe transmitter,itisnecessarytoconnectaDVMtothe testpoints
indicatedinFigure7. If the receiverisnearby,you maysimplyobservethedigitaldisplayon thereceiver.
Ifthe sensordoesnotrespond, it should be replaced.
SENSOR REPLACEMENT
Combustiblegassensors used inthe C12 arewarranted for12 monthsand generallylast5years
ormoreinthe absenceofpoisoningagents.When sensorreplacement isrequired, itcanbe doneeasily
and quickly.Open the transmitterand removethe sensorcablefromthe sensorterminalblockon the
transmittermodule. Unscrewthe sensorfromthe explosion-prooftransmitterhousing using awrenchon
the hexprovided on the sensor. Screwin the replacement sensor.
Connectthe newsensortothe terminalblock(figure3),on thetransmitterboardand replacethe
transmittercover.Afteranewsensorhasbeenconnected, allow4hours forthe newsensorto
completelystabilize. Then performa zero and span calibration asdescribed on pages11 through13.
