Details how to replace the optical encoder that was failing causing wheel spin issues. Optical encoder COATS part number 8110923 available on eBay from seller TANGENTLAB
Here is the link to the encoder on eBay. www.ebay.com/itm/144837664844?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=pn7ypvmhsgm&sssrc=2349624&ssuid=WH7u5PI3Syq&var=&widget_ver=artemis&media=COPY
Great video! can you tell us about the error code you were showing please. I am getting a "No rotation signal-check motor & encoder fuction & wiring-- press stop - exit e3" I replace the micro hood switches already but I still have the same problem. When I lower hood it does not spin on my 1250D. Thank you for any support
Hi Manny, sorry for the delayed reply. That is the same code and symptoms I was getting on my 1400-2D, (Code Error 3- No rotation signal-check motor and encoder function & wiring). It would work sporadically when I lowed the hood and sometimes not at all. Other times it would even spin too fast or slow. All the wiring looked fine so I replaced the encoder 8110923 and that solved it. Hope its not your board, I'm sure that's expensive. How do you know its the board?
Hi tonnygarcia2698, I don't have any experience with ranger balancers but I know a bad encoder caused my coats 1250 to spin uncontrollably at high rate of speed till I turned the power off. Sounds like it could be similar.
Hi rf14dmb, I don't have any experience with the 700 but on the coats machines I'm familiar with there are red indicator LEDs on the circuit board that flash in time with the shaft rotation. If these seem sporadic or inconsistent, its a good sign that the encoder is missing steps.
Hi umershahid, I'm sorry, that's not a problem I've encountered before so nothing definitive comes to mind. But, it sounds like it could be the display circuit board, I'd pull it out and inspect it for moisture or a visibly burned component. Hope that helps, Thanks,
I don't have the codes for a 1050 but error code 4 on a 1250 is reverse spin. I'm not positive but I believe this could be caused by a faulty optical encoder. The 1050 parts manual does list the 8110923 encoder, same as the 1250
