Hey there! If you’re having trouble with your Edwards EST SIGA-MCC1, there are a few steps you can take to troubleshoot the issue. First, ensure that the wiring connections are secure and properly terminated. Sometimes loose connections can cause malfunctioning. Next, check if the module is receiving power correctly. If there are any LED indicators on the module, observe their status to see if they indicate any errors. Additionally, try swapping the module with a known working one to see if the problem persists, which can help determine if the issue lies with the module itself or elsewhere in the system. If none of these steps resolve the issue, it might be best to contact a qualified technician for further assistance. Let me know if you need more detailed guidance!
