So we have a device with a UE9-Pro and a 12VDC motor being controlled via a LJTick-RelayDriver and an SSR. Off of the same LJTick-RelayDriver we are also controlling another SSR that powers on/off some AC heaters. Everything else on the device and the UE9 are working fine, but as soon as the motor turns on we loose communication with the UE9. We figured it had to do with either EMIs from the motor or SSR or with the internal power supply being overdrawn when the motor kicks on (the internal power supply also powers the UE9). So in our trouble shooting we removed the motor from the device and powered it off of an external power supply. When that external power supply was plugged into the same outlet as our device we lost communication, but if it was plugged into another outlet (even if the motor itself was placed inside the device) everything worked fine. We've tried grounding and shielding everything we could and even tried plugging everything into a pretty high-end power isolater/conditioner, but nothing seems to work as long as the motor is drawing power from the same outlet as the UE9. Any suggestions you may have would be greatly appreciated.
Thanks a ton
