Feed mode with 24v jumper

[oldiron]

I have 2 x 6105's running on the 7095 controller all working great. However i have just changed the jumpers from 18v to 24v. Now whenever i use the feed mode the pumps restart within about 60seconds. Changed back to 12v & 18v problem goes away any idea what the cause of this is.

Cheers Michael

Yes, I know about this problem and it is tricky and has no clear universal solution. Essentially a static electric charge builds and the pump is tricked into thinking it is stalling and resets and I have solved it by replacing the power supply or motor or the controller (new controllers since late 2010 have a capacitor system to ignore this reset and in the case of the 7096, a software update fixed this). The ideal is to test everything and replace parts one at a time until it is solved, most often just a power supply is needed, especially if it is the older 6101.240, but is best to have the repair center troubleshoot this.
