Acquity UPLC Sample Manager-FL (Fixed Loop) 'Rotary Tray not calibrated' message
Hello, Our Acquity Sample Manager has been working extremely well for several years until just recently. It is controlled with MassLynx software together with the Acquity UPLC Console. It would beep 3 times and indicate 'Rotary Tray not calibrated' message when 'Wash needle' is attempted. 'Prime syringes' works just fine. I have completed the 'Calibrate Rotary Tray' several times successfully. But it doesn't help. The message keeps coming back. It's not the Rotary Tray calibration issue, but something else. If anyone has encountered this problem before, could you please share your experience on how to solve it? TIA!
