While working on our checklist we found that QD PLC inputs are not making contact. I think Pablo and Brian should check on their side if QD PLC relay's are good (Below is the list of interlock to check, PLC side). To make sure something is not wrong on our side we check the wiring and did continuity tests, and the test passed, hence I suspect issue on the PLC side. We did all of our test by taking connector X15 off and putting jumpers between pins A & H, and between pins J & K.<br></div><br><div>List of interlock to check:<br></div><div>1. Quench Det.
