keyword=Q1 panic button interlock
18:35 Javier noticed Left Q1 down just after the sweep of the Hall was finished at 18:30 (see magnet chart).
Investigation revealed the panic button interlock was on.
Asked for controlled access and went down with Javier to remove the interlock status. Not successful on first attempt of resets because weren't sure about wat was going on.
19:00 called Jack to explain the issue and clarify the procedure, although it sounded like he did the right thing the first time.
Went back to the Hall, Javier discovered that a power supply door was open, setting the panic interlock on.
Closed the door and brought Left Q1 to its set point.
19:25 Called MCC to resume their planned test with beam in the Hall.
