unresponsive flow diverter valve in Sciex 5500

does anybody know how to specifically reset only the flow diverter valve module in Sciex 5000 series instruments, without performing a total hardware reset?

Sometimes, I encounter a problem that the integrated flow diverter valve stays in status "run" even if the run has stopped, and becomes unresponsive to further manual or software commands. The only way of solving this issue is to perform a hardware reset with pumps turning off, so I'd be really grateful if someone found a way of resetting only this module in some sort of way.
Thanks and best regards,
Did you try to deactivate and reactivate the hardware profile?
Good luck
Hi, Jörg,
Thanks for your answer! Yes, I have deactivated the profile, and reactivated it, and unfortunately, it does not reset the valve controller. I even tried shutting down the HPLC and PC, but it does not work either. The only option is to reset or power-cycle the mass detector.
Best regards, Jurij
