2.8Disconnectsequence
AccordingtoKaiDengWVCModem’serialportconnection,pleaseDONOTdisconnectorinstallKaiDengWVCModemto
keepthehardwaresafewhenpoweron.Pleaserefertothefollowingstepstodisconnect:
1.DisconnectKaiDengWVCModempowerplug;

First you need to disconnect
the power of Modem

2.DisconnectWVCModemwithserialportline;
3.DisconnectPCwithserialportline;
4.WVCModemdisconnectedcomplete;
3Operationalenvironment&faulthandling
3.1Naturalenvironment
KaiDengWVCModemisanordinarycommunicationaltrunkingdevice,anditwouldnotworkingoodcondition,orevenbe
damagedinaverybadenvironment.Pleasenotethatnohightemperature,nohighhumidityandnoultra‐lowtemperature
workingenvironment.waterproofboxesneededforoutdoorworkingenvironment,nodirectsunlightexposureandno
extremelycoldenvironmentwithoutheatpreservationdevices.
3.2Applicationenvironment
KaiDengWVCModemtransfersdatabypowerlinescarriercommunicationtechnology,whichhassimpleinstallation,low
cost,highefficiencyandeasymaintenanceadvantagestobringourcustomersenormouseconomicbenefits.Butthereare
requirementsforarrangementofpowerlines:InvertersandWVCModeminthesamegroupshouldbeinstalledwiththe
powerlineinphase,andaddwitha2mHfilterorotherdevicestopreventsignalinterferencefromothergroups.
3.3Errorshandling


1. CheckKaiDengInverterMonitoringsysteminitializationsettings.
Theinitialnumbersandthenumberofgrouphaveadirecteffectonconnectingonline,pleasecarefullycheckthe
numbersrangeofWVCModemandtheparametersoftheinitializationsettingstokeeprelativeuniformity,andtry
again;
2. CheckWVCModeminitializationcompletedornot.
ConnectonlinewouldstartafterWVCModeminitializationcompleted.Firstitwilltakeabout1minutetoinitializea
groupofalltheinvertersafterpoweronandthebluelightwillbecontinuallyflashingandstopuntilinitialization
finished.Intheprocessing,WVCModemhasnoreactionforanyexternalcommunicationrequests;
3. Checkthebootsequenceofsystemequipments.
RightbootsequencespleaserefertoManualSection2.4;
4. Allabovecheckedandsystemonlinefailurestillexists,pleasetrytorunonlinetestingagainafterWVCModem
restartedandinitializationcompleted;
HowtodealwithoneWVCModemfailingtocommunicatecorrectlyinnormalmonitoringprocessing?
KaiDengWVCModemisdesignfor24‐hourworkandlongtimewiththousandstimesoftesting.However,WVC
Modemmaynotcommunicatecorrectlyallthetimeinthebadconditionbelow:hightemperature,moisture,signal
interferenceofpowerlinesandotherfactors.Whenitoccurtothebadsituation,pleasecutthemodempoweroffand
waitafewminutesandthenconnectthepower,theproblemcanbesolvedgenerally.Orcallourlocalafter‐service
branchforsupportandhelpaftertryingseveraltimes.
