cn2450 Posted December 10, 2012 Share Posted December 10, 2012 ive read a few of these post but none seem to describe my particlar problem so hear goes. i have a 16 channel controller with dual power inputs, i have each of the two inputs connected to a gfci each one is a dedicated circuit. channels 1-8 operate fine channels 9-16 not so well. the gfci will trip within 15 sec of me pluging it it (with no lights connected.) so i got out the trusty meter and started checking i think the controler has a problem when i check impedance between netural and hot on channels 1-8 i get nothing no conductive path just like i would expect, chanels 9-16 i get a 100.2 ohm between the leads. this leads me to believe the controler has a problem or am i competly crazzy hear.

Greg Young Posted December 12, 2012 Share Posted December 12, 2012 try plugging power both leads of your controller into one GFCI receptacle, and let us know what happens. Link to comment Share on other sites More sharing options...
LOR Staff Posted December 12, 2012 Share Posted December 12, 2012 You are going to see conductivity between the hot and neutral on one side, since that is the side that powers the electronics. That's not the issue.Something is leaking current from one side to the other. Check all your dongles and connections to ensure that you don't have any nicks in the insulation/etc. Also ensure that the neutrals and grounds are tied together properly -- having a neutral (or in some cases a ground) return to the wrong side will cause the issue as well.

De Trommelslager Posted December 12, 2012 Share Posted December 12, 2012 As Mike stated above, verify all of the dongle connections. Pay close attention to the neutrals! If one has crossed banks (sides), you will have issues. Also, if you have the controller on an extension cord (or cords), rule out the cord(s) by swapping it with another or plug the controller directly into the outlets (unless this is the case).A GFCI detects current flow outside of the circuit, and trips if that measured current exceeds the trip setting. Any current between the hot and neutral of the circuit is ignored by the GFCI. There is a reason your device is tripping; just a matter of finding it.

LOR Staff Posted December 13, 2012 Share Posted December 13, 2012 Ok, that makes things easier... Make sure the neutrals are not reversed. Link to comment Share on other sites More sharing options...
LightORamaJohn Posted December 13, 2012 Share Posted December 13, 2012 GFCIs trip if the current flow is not the same in the hot & neutral indicating that some of the current is taking a side path, possibly through a person. There should be infinite resistance between the hot and ground & infinite resistance between the neutral & ground. Link to comment Share on other sites More sharing options...
Max-Paul Posted December 14, 2012 Share Posted December 14, 2012 Pull out the circuit card, remove the heat sink. Look for any bugs or other critters. If you see nothing, no black marks or anything out of place. Put down paper on the table. Make sure that the board is not libel to move. Then plug it in again. If no trips, then reinstall the heat sink. While doing this, make sure it does not contact any of the circuit paths. And try again. Now look inside of the box and make sure that there is no FOD. Install in box and test. If at any time you have a problem. You might want to create a ticket with LOR. Link to comment Share on other sites More sharing options...
cn2450 Posted December 14, 2012 Author Share Posted December 14, 2012 thanks for all the help i ended up opening a ticket new board on the way yea Link to comment Share on other sites More sharing options...
