[Dsg-hallb_magnets] [New Logentry] Hall B LCW turned off; cannot perform interlock checks until flow restored

[Probir Ghoshal]

Thanks Tyler, Pablo for coming in the hall and did the best you can do.
The controlled power on Solenoid is in place and will be in place till we complete the solenoid checks first.
Once we are satisfied and completed, we shall move the controller power to the torus MPS (Krister will do that when we complete the work on Solenoid).
The MPS (both) are locked and tagged by Krister. He will be available to do that independent of us.
I will let you know once we are ready to start checks. You can remotely clear the interlocks before you start from home just to check.

Bob, Krister, Calvin - I will wait to hear from either of you once the LCW is restored in the hall and we can do the checks as required clearing the faults.

Regards
Probir

Hall B LCW is turned off for work on the system.

Without LCW flow, internal MPS interlocks cannot be cleared. This interlock is internal to the MPS and cannot be bypassed. The interlock checkout procedure requires all interlocks to be clear before starting the checks.

Interlock checkout will be continued once LCW flow is restored.
