Dusk Switch
DUSW with Intelligent photocell
DANLERS DUSW is IP66 rated and can be surface mounted onto an
external wall. It will switch outdoor lights on at dusk and switch them off after
a chosen time delay or when it becomes light again, repeating each day.
Thelight levelat whichthe lampwill switchon andoffissetbyaluxadjuster.
DUSW has a new ‘intelligent’ calibration process which will remove the site
specic addition of articial light from any decision to switch the lights on/off.”

Installation procedure
1. Pleasereadthesenotescarefullybeforecommencingwork.
Incaseofdoubtpleaseconsultaqualiedelectrician.
2. Theswitchshouldbesitedsuchthatitcanreceivemoredaylightthan
articiallight.Ensurethatanyarticiallightsarenottooclosetotheswitchor
shiningintoit.
3. Theswitchmustbemountedviathefourpre-formedholesonly,no
additionalholesshouldbedrilledthroughtheenclosure.Thespindlemust
pointdownwards,withroombelowtoadjustit.
4. Makesurethepowerisisolatedfromthecircuit.
5. ThedetectorshouldbeconnectedasshownindiagramD.
  L-Livein,N-Neutralin,SL-SwitchedLineout.
6. IMPORTANT-Replaceterminalcover.
7. Oncethewiringhasbeencompletedandveried,switchonthesupplyand

Trouble shooting

Thelampswitchesoffabout1minuteafteritswitcheson.
•Unithasnotbeencalibrated
•ToomucharticiallightisenteringtheDUSKSwitch.
Thelampswitchesontooearlyintheevening.
•MovetheLuxadjusterfurthertowardsclockwise.
Thelampswitchesontoolateintheevening.
•Movetheluxadjusterfurtheranticlockwise.
IftheLEDfailstoilluminate(aftercalibration)eitherREDorGreenandthe
loadswitcheson(afteraminute),thecurrentambientluxislowerthanthe
minimum10Lux(atthecell)andtheswitchcannotbeinhibitedoff.
•SitetheDUSWinapositionthatseesmorenaturallight.

DUSW Time/Lux set-up
Thetimeforwhichthelampwillstayonforcanbeadjustedfrom2to16hoursas
shownindiagramC.Tocheckthespindleissetcorrectly-quickpresstheMODE
button(lessthan4seconds).AREDLEDwillashthenumberoftimesrelating
tothepositionofthespindleasfollows:

LUXCalibrationisrecommendedtotakeplacewhenambientlightlevelsarelow
(preferablyatnightorwithdaylightexcludedasfaraspossible,fromthecalibration
measurement).Setupoftheswitchinglevelontheluxswitchshouldtakeplace
whentheambientluxis“asrequired”fromnaturaldaylight.
WhensetupandcalibratedDUSWwillinhibitthearticiallightsfromswitching
ON, if the ambient measured lux is greater than the user set threshold. If the
articial lights are ON and the LUX then rises greater than the set threshold
(plustheStoredCalibratedHysteresis)theproductwillthenswitchthearticial
lightsoffafterthe1minutexedtimedelay.
1.RotatetheLUXpotfullyclockwise.(MinimumcontrolLux)
2.RotatetheTIMEdelaypotfullyanticlockwise.
3.Press and hold the MODE push button for 4 seconds. The status LED
flashes RED/GREEN. The unit will go into calibration mode, where
it measures the addition of LUX from the controlled artificial light
source. This eliminates the possibility of artificial lights switching on,
then off (cycling) after the under/over lux time windows have elapsed.
Luxsamplingiscompleteafter5minutesallowingthearticiallightsourceto
warmuptofulloperatingluxoutput.
4.Ensureareaisnotoccupiedwhencalibrationistakingplace.Ensuretheproduct
issitedsuchthattheluxcellcanseeonlythereectedlightofthesourceitis
controlling,NOTotherswitched/varyingarticiallightsources.
5.Ifmovedfromitsoriginalcalibrationsite,itwillneedtobere-calibrated.
6.Afterapprox.5minutestheLEDwillstopashingRED/GREENandshouldgo
xedGREEN(abovethreshold)ORwillnotbeilluminated(belowthreshold).The
controlledlampswillbeheldofffor1minute.Thenthecurrentluxwilldetermine
theswitchstate.Ifthecurrentluxlevelisbelowthelowestinhibitthresholdof
10LUX,thecontrolledlightswillbeswitchedon.Ifthecurrentluxlevelisabove
thelowestinhibitthreshold,theloadwillbeforcedoff.
7.IftheLEDisxedgreen,thisindicatesthatthecurrentLUXcontrolsettingin
additiontothearticialLUX(ascalibrated)is“inrange”oftheproduct(1000
LUXmaximumonthecell)andcanbecontrolledwithoutlampcycling.
8.IftheLEDisxedRED,thistellstheuserthatthecurrentLUXcontrolpoint(pot
setting)inadditiontothearticialLUX(measuredincalibration)isnearingthe
rangelimit/isOUTofrangeoftheproduct,(1000LUXmaximumonthecell)
andthelightsMAY/WILLcycle.
Note:AstheluxpspindleismovedanticlockwiseitmaybethattheLEDgoesfromxedgreen
toxedredbeforeitgoesoff.ThisinformstheuserthatthecurrentLUXcontrolpointinaddition
tothearticialLUXiseitherin rangeoroutofrange.Whenmovingthepot anticlockwise, if
theLEDgoesREDbeforeitgoesoutthentheLUXcontrolpointneedstobeadjustedlower
ORtheunitrepositionedwithrespecttothecontrolledload,sothatitisNOTseeingasmuch
articiallightandthenrecalibrated.
9.Aftercalibration:(Withtheloadinhibitedoff).Whentheambientluxhasreduced
tothelevelyourequirethelampstoswitchon,assumingtheLEDisxedgreen
(potfullyclockwise),movethepotanticlockwiseuntiltheLEDgoesoff.This
needstobedoneinsmallincrementsbyadjustingthepotandmovingwellout
thewayoftheLUXcell.EnsuretheLEDisstilloffwhenfullnaturaldaylightis
seenbythecellatthatparticulartime.i.e.notshadedbythecommissioning
“body”.After1minutetheloadshouldswitchon.
