Before you enter authorization code—including 120 —you must understand that changing protection settings on a live system can cause electric shock, arc flash, or equipment destruction.
Sometimes the relay is not rejecting the code—the software is simply not sending it. Check your RS485 termination resistors and ensure the Sepam is in "Local" or "Remote" mode as required. authorization code sft2841 120
The Schneider Electric SFT2841 software is the primary setting and monitoring tool for Sepam series protection relays. To unlock the full capabilities of this engineering software, users often require a specific authorization code, particularly when working with versions related to the "120" designation, which typically refers to a specific software release or a bundle for the Sepam 100 series.
