text: <s>[INST] PF 755 Fault Code 212 Summary: Intermittent, incorrect fault code 212We've got a couple of PowerFlex 755 drives in completely separate areas, no safety option module installed, but the Safety Jumper is installed. We're getting intermittent, random Fault Code 212 Safety Jmpr Out. So far, the only tech support response we've gotten is noise. Has anyone here seen this problem and possible have a solution to it? Much appreciated. [/INST] Maybe something's wrong with the jumper itself? There are two jumpers on the control board, right next to each other - the safety jumper and the hardware enable jumper. Try swapping the two jumpers. If the fault changes from Safety-Jumper-Out to HW-Enable, the jumper is bad. If the problem continues to be the safety jumper out fault, maybe consider changing the control board itself? What firmware is installed on the drives? \\n </s>
