7 Troubleshooting

7.1 The Control Panel is Blank or the Cleaning Station Does

Not Run

• Checkthatthewaterlevelinthetankisnotbelowapproximately2.54cm

(1inch)fromthetopofthetank.

• Checkthatthecleaningstationispluggedintoawallsocketandthatthe

socketislive.

• Checkthatthecleaningstationisturnedon.

• Checkforablownfuse.

Whenreplacingfuses,alwaysdisconnecttheDT3CleanStationfromthe

wallsocketandkeepthepowercableinview,sothatitisnotaccidentally

pluggedbackin.

Tocheckandreplacethefuse:

1. Disconnecttheunitfromthewallsocket.

2. Locatethefusesbehindthetank.

3. Unscrewthefusecovers.



Figure7Fuses

4. Checkthefuseswithanohmmeter.

Note: Ablownfuseusuallyindicatesthatthereisanelectricalfault.

Tochecktheconditionofthewiring:

1. DraintheDT3CleanStationandtipitsothatitisrestingonitsleftside(when

viewedfromthefrontpanel).

2. Inspectthewiresunderthecleanstationandcheckthattheyareundamaged.

DT3 CleanStation

DOC-01121 Rev. A 3-16

7.2 Printed Models Take a Long Time to Clean

• Checkthecleaningsolutionwithahydrometerandchangethesolution,if

necessary.Forinstructionsonusingthehydrometer,seeDOC-08380,

"WorkingwithAlkalineCleaningSolution".

• Checkthatthesuctionstrainerandthemanifoldjetsareclearofmaterial

deposits(see"Maintenance"onpage12).

7.3 Error Messages on the Control Panel

Ifanerrorisdisplayed(suchasErr4orErr5),contactyourStratasys

representative.

7.4 The DT3 CleanStation Stops Mid-Cycle

• Checkthatthewaterlevelisatleast2.54cm(1inch)fromthetopofthetank.

• Checkthatthesuctionstrainerandthemanifoldjetsareclearofmaterial
