TheSmartWirelessFieldLinkandWirelessI/Oshouldbeinstalledandfunctioningproperlybeforethepower
modulesareinstalledinanywirelessfielddevices.Wirelessfielddevicesshouldalsobepoweredupinorderof
proximityfromtheFieldLinkbeginningwiththeclosest.Thiswillresultinasimplerandfasternetworkinstallation.
MountingLocation
TheFieldLinkshouldbemountedinalocationthatallowsconvenientaccesstothehostsystemnetwork(wireless

Grounding
TheFieldLinkenclosureshouldalwaysbegroundedinaccordancewithnationalandlocalelectricalcodes.The
mosteffectivegroundingmethodisadirectconnectiontoearthgroundwithminimalimpedance.Groundthe
FieldLinkbyconnectingtheexternalgroundlugtoearthground.Theconnectionshouldbe1Ωorless.
STEP2:VerifyOperation
Addlocaldisplayscreenshere.
Power‐UpSequence
UponapplyingpowertotheFieldLinktheLCDmeterwillactivateanddisplayaseriesofstartupscreen.The
followingscreensaredisplayedduringstartup.
1. StartupScreen1–Allsegmentson
2. StartupScreen2–DeviceIdentification
3. StartupScreen3–Tag
4. StartupScreen4–Status
NormalOperation
AftertheinitialstartupscreenstheFieldLinkwillcyclethroughseveralperiodicscreens.
1. ElectronicsTemperatureScreen
2. PercentRangeScreen
3. WiredInterfaceUsage
4. RadioInterfaceUsage
Thefieldlinkwillcontinuetorotatethrougheachperiodicscreenthroughthecourseofnormal
operation.Ifanydiagnosticorfaultconditionoccurs,acorrespondingdiagnosticsscreenwillappear.
