Anoutlettube fitting isalsosupplied on the flowmanifold.Ordinarily,allowing the small

GASCONCENTRATIONALARMFUNCTIONS
The PortaSensII LeakDetectorcontainsbothvisualand audiblegasconcentration
alarmfunctions.Three alarmlevelsareprovided,withadjustablesetpoints(SP) foreachalarm.
The alarmsaredesignated asCAUTION,WARNING, and ALARM.The Caution setting is
normallyadjusted toalarmif the installed gassensorexhibitsexcessivenegativezerodrift. The
Warning and Alarmlevelsaresettospecificgasvaluestoprovide an indication ofhigh
concentrations.Notethatthe Caution,Warning,and Alarmfunctionsareonlyactivewhen the
C16 isoperating inthe normalmode.When inCalibrateorSampling modes,the alarmsare
disabled.
When the gasdetectorisinoperation,the measured gasconcentration isalways being
compared tothe alarmsetpoints.When the concentration exceedsthe Warning set-pointfor2
seconds,the LCD displaywillflashthe message "WARNING"and the audiblebeeperwillsound
intermittently.If the Alarmset-pointisexceeded, the displaywill flashthe "ALARM"message and
the audiblebeeperwillsound continuously.Ifexcessivezerodriftisdetected,the Caution
message willflash,indicating thatthe sensorzeroshouldbe checked and adjusted ifnecessary.
The Caution alarmwillnotactivatethe internal horn.Tosilencethe alarmhornand stop the
displayflash,pressthe ACKkey.Notethatthe alarm acknowledge key(ACK) willonlyappear
during an alarmcondition. Allalarmset pointscan bechanged bytheuserorcanbe turnedoffif
desired. Refertothe instructionson page 21 forthe properadjustmentprocedures.
PUMPTROUBLEALARM
Aninternaldiaphragmpumpcontinuouslydeliversanairsampletothe flowmanifold
containing the gassensor.Innormaloperation, the flow rateisapprox.400 cc/min.Blockage in
eitherthe inletoroutletwillincreasethe sampletransporttimetothe analyzer,resulting ina
muchslowerresponsetime.Shouldthe pumpfailduring normaloperation,the LCD displaywill
indicatethe message "PUMP TROUBLE"and the internalaudiblehornwill sound intermittently.
The internalpumpwillgenerallynotbe damaged byshortterm operationwiththe flow
blocked.Itispossibleforthe pumpmotortorun,even when thereisno airbeing pumped
through the system.Thiscondition can occurifthe pumpisfilled withwaterorifthe filter
becomescompletelyblocked.Aflowmeterisincluded inthe PortaSensII kittoallowquick
verification of properflow.Turnthe instrumenton and connectthe sampling wand.Placethe tip
ofthe sampling wand intothe tubing adapterattached tothe flowmeter. Holdthe flowmeterinthe
verticalposition and verifythatthe flowrateisabove250 cc/min(0.5SCFH).Proper flow
shouldalways beverifiedbefore using thePortaSensforleak testing.

SENSORMODULEEXCHANGE
The versatilityofthe PortaSensII leakdetectorstemsfromitsabilitytouseavarietyof
sensormodules. Theseinterchangeablemodulesallow one instrumenttomeasureawide
varietyofgaseswithextended range capabilitiesasdescribed inthe Introduction section.
Exchanging one sensormoduleforanotherisasimpleprocedure. Onthe back ofthe
instrument aretwostainless steelthumbscrewswhichholdthe flowmanifoldinplace.Loosen
thesetwoscrewsand removethe manifoldlid. The installed sensorisablack cylinderwithwhite
membrane inthe cavityrecess. Toremove, simplygrabthe sidesof the sensormoduleand pull
itstraight back.The sensorisheldinplacewithaminiatureconnectorforeasyremoval.
Toinsert anewsensormodule, placethemoduleconnectorfirstintothe recess and
rotateasneeded untilthe modulekeylinesup withthe guide on the bottomof the recess. The
sensormodulecan then be pressed inplace,fullyengaging the connector. When fullyinserted,
the faceof the sensormodulewillbe flushwiththe outersurfaceof the cavity.
Replacethe manifoldlidand tighten thethumbscrewssecurely(hand tight issufficient).
Afteramodulechange,verifythe flowthrough the sampling wand using the flowmetersupplied
withthe unit.See Figure4onPage 19.
The detectorcan be on oroff during asensormodulechange. If the powerison during a
change, the displaywillindicate“SENSORMISSING”whenthe sensormoduleisremoved.
Whenthe moduleisreplaceoranewone isinserted, the displaywilldisplaya“LOADING”
message, indicating that sensormoduledataisbeingtransferred fromthe sensormoduleintothe
detector.
NOTE: Sensors cantake up to 12 hours to stabilize(bias)ifnotpreviouslyparked in the
sensorkeeper orinstalledin thesensorchamber in thePortaSensII.
