Estimated Duration:
2 weeks
Reason for Defeat:
EACA:IP1E must be run in local mode due to a faulty cable (E-Fault 15848). So to allow the ion gauge in the same section (EACA:IG1E) to remain running, it must be bypassed.

How Was Defeat Implemented?
Where is Defeat Located?:
EACA:IG1E interlocks were bypassed through the Bypass/Force function in EPICS. EACA:IG1E is physically located in the E-Hall and it's controller is on the E-Hall roof.
Describe Alternate Protection:
If the pressure becomes too high, the IG has its own electronically embedded protection to trip off. Confirmed that RF trip box will still trip if IG reading gets too high.

Interlock Verification Method:
Confirmed that turning off EACA:IP1E caused EACA:IG1E to trip off. See e-log entry https://web.accel.triumf.ca/elinac_elog/Elog_show_result.pl?inid=50307&style=entry&timemode=eventtime for details.
