BELS Beam Shutdown Test

Notes
Figures 1-5: EPICS Envelope Test
-Figure 3: green indicator on limit setup screen stays green when limit is exceeded, including 60s warn point and 240s trip point

-Figure 4: Only one channel latches a major alarm when BELS trip occurs. This is because the A and B chains use independent timers that are a few seconds (< 5s) out of sync. One chain hits 240 s first and trips the beam, which stops the timer for the other.

Figures 6-13: Operations Envelope Test
Figure 7: The Ops Power Trip Limit field is either not archived or the PV is not displayed on the warning limit screen.

COMMENT ON Work requiring returning MMA1H01 to operation

MMA1H01 was ramped up to 400A but tripped off on magnet overtemperature. Taking a look in the hall, discovered that an upstream valve supplying the magnet LCW was turned off. Talking with the hall coordinator, they were able to reconfigure the valves so that we may continue our testing of the power supply into the magnet load.
