2. Handling Cautions
Thischapterprovidesimportantinformationonhow
tohandlethetransmitter.Readthiscarefullybefore
using the transmitter.
EJX Series transmitters are thoroughly tested at the
factorybeforeshipment.Whentakingdeliveryofan
instrument,visuallycheckthemtomakesurethat
nodamageoccurredduringshipment.
Alsocheckthatalltransmittermountinghardware
showningure2.1isincluded.Ifthetransmitter
isorderedwithoutthemountingbracketandthe
processconnector,thetransmittermounting
hardwarewillnotbeincluded.Aftercheckingthe
transmitter,carefullyrepackitinitsboxandkeepit
there until you are ready to install it.

humiditywithinthefollowingranges.
Ambient temperature:
 –40to85°C
 –30to80°CLCDvisiblerange
Relative humidity:
0% to 100% R.H.
Preferred temperature and humidity:
 approx.25°Cand65%R.H.
(b) Whenstoringthetransmitter,repackitcarefullyin
thepackagingthatitwasoriginallyshippedwith.
(c) Ifthetransmitterhasbeenused,thoroughly
cleanthechambersinsidethecoveranges,so
thatthereisnoprocessuidremaininginside.
Beforeplacingitinstorage,alsomakesurethat
thepressure-detectorissecurelyconnectedto
thetransmittersection.
(d) Preferablyremovethebatteriesforstorage.For
maximum battery life, the storage temperature
shouldnotexceed30°C.
NOTE
Whenstoringtheinstrumentwithabattery
pack,itisrecommendedtoputtheinstrumentin
DeepSleepmodetoconservethebatteries.For
detailsonhowtoswitchtoDeepSleepmode,
refertosubsection8.3.16“SwitchingtoDeep
SleepMode”.
2.4 Selecting the Installation
Location
Thetransmitterisdesignedtowithstandsevere
environmentalconditions.However,toensure
thatitwillprovideyearsofstableandaccurate
performance,takethefollowingprecautionswhen
selectingtheinstallationlocation.
(a) WirelessCommunication
NOTE
Theinstallationlocationofthistransmittermust
meetthefollowingconditions:
- Adjustthedirectionoftheantennatobe
in the upright position regardless of the
orientationofthistransmitter.Seesection4
for adjusting the antenna.
- Install the transmitter at least 1.5m above
thegroundoroor.
F0203.ai
1.5m or more
- Ensurethattherearenoobstaclessuchas
wallsorpipeswithina30-cmradiusofeach
antenna.
- Conrmthateacheldwirelessequipment
compliantwithISA100.11acanseethe
antennaofotherdeviceswhichlocatewithin
itsowncommunicationrange.Inthestar
topologynetwork,thevisibilitytotheantenna
ofgatewayisamandatoryclause.

<2. Handling Cautions> 2-3
IM 01C27B01-01EN
(b) AmbientTemperature
Avoidlocationssubjecttowidetemperature
variationsorasignicanttemperaturegradient.
Ifthelocationisexposedtoradiantheatfrom
plant equipment, provide adequate thermal
insulation and/or ventilation.
(c) AmbientAtmosphere
Donotinstallthetransmitterinacorrosive
atmosphere.Ifthiscannotbeavoided,there
must be adequate ventilation.
(d) ShockandVibration
Although the transmitter is designed to be
relativelyresistanttoshockandvibration,an
installationsiteshouldbeselectedwherethisis
kepttoaminimum.
(e) InstallationofExplosion-protectedTransmitters
Anexplosion-protectedtransmittersis
certiedforinstallationinahazardousarea
containingspecicgastypes.Seesubsection
2.8“InstallationofanExplosion-Protected
Transmitters.”
2.5 Pressure Connection
WARNING
• Neverloosentheprocessconnectorbolts
whenaninstrumentisinstalledinaprocess.
Thedeviceisunderpressure,andalossof
sealcanresultinasuddenanduncontrolled
releaseofprocessuid.
• Whendrainingtoxicprocessuidsthathave
condensedinsidethepressuredetector,
takeappropriatestepstopreventthecontact
ofsuchuidswiththeskinoreyesandthe
inhalationofvaporsfromtheseuids.
Thefollowingprecautionsmustbeobserved
in order to safely operate the transmitter under
pressure.
(a) Makesurethatalltheprocessconnectorbolts
aretightenedrmly.
(b) Makesurethattherearenoleaksintheimpulse
piping.
(c) Neverapplyapressurehigherthanthe
speciedmaximumworkingpressure.
2.6 Restrictions on Use of Radio
Transceivers
IMPORTANT
Although the transmitter has been designed to
resisthighfrequencyelectricalnoise,ifaradio
transceiverisusednearthetransmitterorits
externalwiring,thetransmittermaybea󰀨ected
byhighfrequencynoisepickup.Totestthis,start
outfromadistanceofseveralmetersandslowly
approachthetransmitterwiththetransceiver
whileobservingthemeasurementloopfornoise
e󰀨ects.Thereafterusethetransceiveroutside
therangewherethenoisee󰀨ectswererst
observed.
2.7 Insulation Resistance and
Dielectric Strength Test
Sincethetransmitterhasundergoneinsulation
resistanceanddielectricstrengthtestsatthefactory
before shipment, normally these tests are not
required.Iftheneedarisestoconductthesetests,
heedthefollowing:
(a) Donotperformsuchtestsmorefrequentlythan
isabsolutelynecessary.Eventestvoltagesthat
donotcausevisibledamagetotheinsulation
maydegradetheinsulationandreducesafety
margins.
(b) Neverapplyavoltageexceeding500VDC
(100VDCwithaninternallightningprotector)
fortheinsulationresistancetest,noravoltage
exceeding500VAC(100VACwithaninternal
lightningprotector)forthedielectricstrength
test.
(c) Theprocedureforconductingthesetestsisas
follows:

<2. Handling Cautions>2-4
IM 01C27B01-01EN
• Insulation Resistance Test
1)Removethebatterypackorpowersupply
module.Seesubsection9.4.6Replacingthe
BatteryPackor9.4.9ReplacingthePower
Supply Module.
2)Short-circuitthebatteryconnectionterminalsin
the terminal box.
3)TurnOFFtheinsulationtester.Thenconnect
theinsulationtesterplus(+)leadwiretothe
shortedbatteryconnectionterminalsandthe
minus(–)leadwiretothegroundingterminal.
4)TurnONtheinsulationtesterpowerand
measuretheinsulationresistance.Thevoltage
shouldbeappliedasbrieyaspossibletoverify
thattheinsulationresistanceisatleast20MΩ.
5)Aftercompletingthetestandbeingverycareful
nottotouchexposedconductorsdisconnectthe
insulationtesterandconnecta100kΩresistor
betweenthegroundingterminalandtheshort-
circuitingbatteryconnectionterminals.Leave
thisresistorconnectedatleastonesecondto
dischargeanystaticpotential.Donottouchthe
terminalswhileitisdischarging.
NOTE
Whenstoringtheinstrumentwithabattery
pack,itisrecommendedtoputtheinstrumentin
DeepSleepmodetoconservethebatteries.For
detailsonhowtoswitchtoDeepSleepmode,
