tolocatetheswitchesfortheseseings.
Proceedasfollows:
1. Removethescrewatthecenteroftheinterfacethatsecuresthecoverand
removethecover.
2. Locatetheappropriateswitch(seeIllustration8).
3. IftheRS-485connectionistheEnd-of-Line(onesetofwiresundertheRS-485
terminals),verifythatbothswitchesontheRS-485switchassemblyareinthe
ONposition.Otherwise,theswitchesshouldbeintheOFFposition.

Power Connection
Connectthe24VACsupplyvoltage(Class2transformeronly)tothepowerter-
minalsonthelowerlesideofthecontroller.Connect the neutral lead from the
transformer to the GND terminal and the AC phase lead to the ~ (phase) termi-
nal. PowerisappliedtotheKMD-5540whenthetransformerispluggedinandthe
powerjumperisinplace(seeIllustration 1—Controller Components on page 2).
Configuration
PriortooperatingtheKMD-5540,itmustbeconguredusingtheHardwareCon-
gurationManager(HCM)applicationsuppliedwithWinControl.SeetheWin-
ControlXLUser’sManualforadditionalinformation.
Note:
Alldevicesonthesamenetworkmustbeconguredforthesamebaudrate.
Operation
Oncecongured,programmed,andpoweredup,theinterfacerequiresverylile
userintervention.
Controls and Indicators
Thefollowingsectionsdescribethecontrolsandindicatorsfoundonthedevice.
Network ON/OFF
ThenetworkON/OFFswitchislocatedbelowthemodularjackonthelesideof
thecontroller.UsethisswitchtoenableordisabletheRS-485networkconnection.
Alternately,youmayremovetheRS-485terminalblockfromthepinstocomplete-
lyisolatetheKMD-5540fromthenetwork.
Status LEDs
TwostatusLEDsarelocatedonthelesideofthecontrollerabovethepowercon-
nectorterminal.Theyareusedtoindicatethefollowing:
RDY –TheReadyLEDblinksrapidlywheneverthecontrollerisoperatingnor-
mally.YoucanconsiderthisthesameasapowerLED.
COM –TheCommunicationsLEDindicateswhenthecontrolleristransmiing
overtheRS-485networkconnection.
Isolation Lamps
TwoisolationlampsarelocatedneartheNetworkON/OFFswitch.Theselamps
servethreefunctions:

◆ RemovingthelampswillopentheRS-485circuitandisolatetheKMD-5540
fromthenetwork.
◆ Ifoneorbothlampsarelit,itindicatesthenetworkisimproperlyphased.This
meansthatthegroundpotentialoftheKMD-5540isnotthesameasotherde-
vicesonthenetwork
◆ Ifthevoltageorcurrentonthenetworkexceedssafelevels,thelampsoperateas
fusestoprotecttheKMD-5540fromdamage.
Resetting the Controller
IftheKMD-5540appearstobeoperatingincorrectly,orisnotrespondingtocom-
mands,youmayneedtoresetit.
Note
Reseingtheinterfacewillrestorethefactorydefaultconguration.
Itmaybenecessarytore-conguretheKMD-5540withHCMtoestablishnormal
communicationsandoperation.
ToresettheKMD-5540,proceedasfollows.
1. Removethescrewatthecenterofthethecoverandremovethecover.
2. Locatethejumperblocknexttotheinputpull-upswitches(seeIllustration9).
3. RemovepowertotheKMD-5540.
4. PlaceashortontheRSTpins.Useajumperifaspareisavailable.
5. PoweruptheKMD-5540.WaituntiltheRDYLEDbeginstoashnormally.
6. RemovepowertotheKMD-5540.
7. RemovetheshortfromtheRSTjumper.
8. Reinstallthecoverandscrew.
9. PoweruptheKMD-5540andre-congureitifnecessary.
