Both Probir and I tried resetting the Torus MPS interlock remotely. It would clear for a few seconds then trip off again with the same errors that Denny reported.

Made an controlled access, tried resetting the MPS locally, same issue.

Probir removed AC power to the MPS and we visually inspected the flow sensor boards and made sure all the connections were good (nothing obviously wrong there). Checked the manifold where the flow switches are located and noticed two small leaks (see attached photos). Not anything that should cause an interlock though.

Before putting the MPS on control power and troubleshooting further AC power was restored and the MPS interlocks were cleared and they stayed clear this time. Ramped to 100A with no issues.
