Estimated Duration:
52 weeks
Reason for Defeat:
The vacuum in the EHDT:DB6B vacuum section is too good with EHDT:IP6 and EHDT:NP6 running for EHDT:IMG6 to read. So IP6 is turned off and the EHDT:IMG6 interlocks are bypassed to allow it to run.

How Was Defeat Implemented?
Where is Defeat Located?:
EHDT:IMG6 interlocks were bypassed through the Bypass/Force function in EPICS. EHDT:IMG6 is physically located in the E-Hall.
Describe Alternate Protection:
According to Dimo: if the pressure becomes too high, IMG6 has its own electronically embedded protection to trip off. Dimo approves for the EHDT:IMG6 interlock bypass to be implemented for a non-short term duration.
