Manual Tuning
NOTE:Forthisprocedure,refertoFIGURE 22.2.
1. Turnpoweroff()andunplugtheunit.
2. Removecabinet.RefertoRemovingCabinetonpage 23.
3. PlugunitinbutDONOTturnon()untilinstructedtobelow.
4. LocatethetimingswitchontheP. C . board.
5. Insertasmallcommonorflatheadscrewdriverintotheadjustmentscrewofthetiming
switch.
6. Setthetimingswitchinitiallyatthenumber“7”position.
7. Turnuniton()andwait15minutesforunittostabilize.
8. Ifafter15minutesofruntimetheconcentrationisbelowspecification,changesetting
toanumberonepositionlowerthantheprevioussetting.
9. Letunitruntenminutes.Ifconcentrationislowerstill,changetheswitchtonumber
twopositionshigher.
NOTE:Yo uwillfindthat theconcentratorwillperformbetterateitherthehigherorlowersetting.
Thenormaladjustmentrangeisbetweentimingpositions3andA.
10. Continuetochangesettingonestepatatime(upordown)untiltheconcentrationis
thehighestvalueachievable.
11. Onceconcentrationhasreachedspecification,retimingiscomplete.
12. Reinstallcabinet.RefertoRemovingCabinetonpage 23.
