Hello, I am currently utilizing the E300 as the E3 Plus in emulation mode, which is Rockwell Automation's overload relay. However, I am encountering a hardware fault when I enable the Ground Fault from the trip or warning enable parameter. This issue is similar to the one described in a technote (Knowledgebase ID: QA59485) that is accessible with an RA account. Disabling the ground fault resolves the fault, but the solution provided in the technote has not been effective for me. I have verified the firmwares and eds files, but the fault persists. My setup includes the 193-ECM-DNT, 193-EIOGP-42-24D, 193-CBCT2, and 193-ESM-I-60A-C55 components, emulating the E3 Plus (9-45 A) model. Despite having the correct firmware versions, I am unable to change the firmware while in emulation mode. I am seeking a solution to rectify this issue. Your insights or suggestions would be greatly appreciated. Thank you.
Hello Asefakaratas, I am experiencing similar issues. Have you discovered a resolution to this problem?
Hey there, I've worked extensively with the E300 and ran into similar issues myself. One thing you could try, outside of what you've already done, is checking your DIP switch settings on your 193-ECM-DNT card. Make sure they're correctly set to match your application. I'd also suggest reviewing your setup in RSLogix 5000 to ensure your input and output assemblies are accurate. Sometimes, small oversights like these can cause persistent faults like you're experiencing. Hope this helps and all the best in resolving your issue!
Hey there, I've had similar issues with the E300 previously. One thing that stood out to me from your post is that you're trying to change the firmware while in emulation mode, that's typically not advised as it can lead to errors. Also, you might want to check that there's no issue with your electronics module. The E300 can be very finicky about the smallest inconsistencies there. Assuming that's not the problem, I'd suggest reaching out directly to Rockwell's tech support. They've been very helpful with more intricate problems I've encountered in the past.
It sounds like you've been very thorough in your troubleshooting, which is commendable. One potential avenue you might not have explored is checking whether there's a ground fault present in your system for real. Even if the E300 is in emulation mode, it might be detecting a ground fault in your setup and rightfully tripping. If you've not done so already, consider physically checking your system or set up to confirm the absence of a ground fault. If none is found, then it might be an issue with the E300's ground fault detection mechanism which might require a replacement. Notify Rockwell about your specific situation as they might offer additional solutions or replacement options.
