THE FLEXIBLE CONTROL
• TheFD113OilPressureSafetyControlsensestheeffectiveoil
pressuredifferentialincompressorswithpositivedisplacementoil
pumps.Ifinadequateoilpressureexists,atimedelayisenergized.
Iftheoilpressuredoesnotrecovertosafelevelswithinthetime
delaysetting,thecompressorisshutdown.Thetimedelayallows
thecompressoradequatetimetoestablishoilpressureonstart–up
andavoidsnuisanceshutdownsonpressuredropofshortduration
duringtheruncycle.
• Maximumapplicationexibilityisassuredbyprovidingan
adjustabledifferentialpressureswitchwhichcanbeadjustedto
thecompressor’sminimumrequiredoilpressureneedsandan
adjustabletimedelaywhichallowsyoutoselectthelengthof
timethecompressorrunsbelowtheminimumpressurebefore
shutdown.Theminimumpressuresettingandtimedelayvalues
speciedbythecompressormanufacturershouldbeusedwhen
installingtheFD113control.
FEATURES
• PressureRangeadjustablefrom4to65PSID.
 Timerstartpressure–timerstoppressureis3PSIDabove
timerstartpressure.
• ASPDTswitchisusedinthepressureportionofthecontrol
whichallowstheadditionofa“safelight”ifdesired.
• TimerisTime–Adjustablefrom20to150seconds.
 Supplyvoltage–24to240VoltAC/DC.Timingunaffectedby
voltageorambienttemperaturevariations.
• ASPDTManualResetSwitchisusedintheTimerModule.
 Upontime-out,thecompressorisstoppedandanalarmcircuit
isenergized.Torestartthecompressorandde-energizethe
alarmcircuit,theresetbuttonispushed.
• AfactoryinstalledJumperallowstheFD113tobepoweredfrom
asinglepowersource.Shouldseparatecircuitsbedesiredfor
thetimerand“Lockout”switch,theJumpercanberemoved.
SAFETY INSTRUCTIONS
1. ReadallInstructionsthoroughly.Failuretocomplycanresult
incontrolfailure,systemdamageorpersonalinjury.
2. Donotusewithammoniaoronhazardousorcorrosiveuids.
3. DonotinstallinHazardousLocations.
4. Disconnectelectricalpowerbeforeinstallation.Donotreapply
poweruntilcontrolinstallationiscomplete,wiringconnections
securedandcoverisinplace.
5. Beforemakingpressurecontrolconnections,depressurize
systemandmakecertainlinesareatatmosphericpressure.

INSTALLATION INSTRUCTIONS–GENERAL
1. Cover Removal—Loosencoverscrew,pullcoverforward.
2. Mounting—Mountthecontrolinaprotectedareaonthe
 mountingbracketoraatsurfacewithscrewsprovided.
 CAUTION:Ifotherscrewsareused,use8-32screwsthat
do notpenetrateintothecontrolmorethan1/8’’.
 OilPressureSafetyControlsshouldalwaysbemounted
 abovetheoillevelinthecompressorcrankcase.The
 capillarytubesorpressureconnectionsshouldberouted
 toallowthemtobefree–drainingtothecompressor
 crankcase.Thiswillpreventoillogginginthecapillary
 tubesduringlowambientconditions.
3. Capillary Tube Connections:Properinstallationof
 capillarytubesand/orpressurecontrollineswillinsure
 atrouble–freeinstallation.WARNING:Beforemakingany
 pressurecontrolconnections,depressurizesystem.Failure
 todosocancausesystemdamageorpersonalinjury.
 • Ifthecontrolismountedonthecompressor,alllines
  mustbesecuredtothecompressorsotheydonot
  vibrateindependentlyfromthecompressor.
 • Ifthecontrolismountedremotefromthecompressor
  anopencoiledvibrationloop,2to3coils,2to3’’
  diametershouldbeprovidedbetweenthecompressor
  baseandthemovingcompressor.Thelinescoming
  fromthecoilshouldbesecuredtothebaseand
  compressorsothecoiltakesallthevibration.Avoid
  any“violinstring”runsofcontrolcapillarytubes.
 • Sharpbendsorkinksmustbeavoidedinthecapillary
  orpressurelines.Donotallowthelinestoruband
  abradeagainstanymovingsurface.Avoidanyexcess-
  ivehandlingorreformingofthecopperlinesto
  minimizeworkhardeningofthecopper.
4. Electrical Connections—WARNING: Beforemakingany
 electricalconnections,disconnectallelectricalpower.
 Checkwithavoltmeterasmorethanonesourceofpower
 maybesupplied.Makecertaintheloadtoconnectedis
 withintheelectricalratingofthecontrol(seeTable1).
 • AllwiringshouldconformtoNationalElectricalCode
  and/orlocalcodes.Use14AWG or larger copper
conductors ONLY.
 • Theterminalsareofaclampdesign.Loosenthe
  terminalscrewswithasmallscrewdriver,insert
  approximately3/8’’strippedwireandsecurelytighten.
