SENSOR ADJUSTMENT

DO NOT OVERTURN TRIMPOTS WHEN ADJUSTING THE SENSOR!

1. Totestunitoperation,presstheON/OFFbuttontoturntheloadon.

2. Removethebuttoncovertoaccesstheadjustmentcontrols.Useasmall,

atbladescrewdrivertopressdownthelockingtabatthetopofthebutton,

thengentlypryitoff.

a)Setthetimedelaytothe“walktest”position(fullycounterclockwise).

b)Leavetheroom.Theloadshouldgooffafter30seconds.

3. Totestsensitivity:

a) Makenomotionfor3seconds.

b) Waveyourhandsidewaysinfrontofthesensoratadistanceof

approximately12".TheLEDblinkswhenmovementisdetected.

Typically,thesensitivityshouldbeatmaximum(fullyclockwise).

4. Setthelightlevelwhenthecontrolledlightwouldnormallybeturnedoff

duetothepresenceofsufcientdaylightorotherelectriclight.[Ifthis

featureisnotneeded,leavethelightlevelatmaximum(fullyclockwise)].

a) SettheTimeDelaytoatleast5minutes.Thistakesthesensoroutof

Walk‑testmode,andenablesthelightlevelfeature.

b) SettheLightlevelto50%(12o’clockposition)whichisapproximately

100fc.Letthesensortimeoutsolightsareoff.Enterthespaceand

c) Makesureyourbodydoesnotcastashadowonthesensor,andadjust

thelightleveltrimpotclockwiseinsmallincrements.

d) Aftereachadjustment,wait5‑10secondstoseeifthelightsturnon.

Repeatuntilthelightsturnon.Atthissettingtheloadconnectedtothe

sensorwillnotturnoniflightlevelsareabovethecurrentillumination.

Note: Userscanoverridethisfunctionbyplacingtheirhandinfrontofthe

1. Connecttheexistingwiresinthewallboxtothesensorflyingleads.

(SeeWiringDirectionsatright).

 • Donotallowbarewiretoshowbelowconnector.

 • Thegroundwiremustbetightly grounded fortheunittooperate

properly.

2. Attachthesensortothewallbymountingitinthewallboxwiththetwo

3. Turnonpoweratthecircuitbreaker.

 There is an initial warm-up period after installation.Itmaytakeuptoa
