 It seems the exhaust line is blocked which caused pressure to build up and eventually forced the exhaust tube off RP2 as RP1 was roughing down the vacuum chamber.

Vacuum group has been notified and will ask plant group to investigate.

Plant group has removed the blockage. Exhaust lines are reconnected to the roughing pumps.

Mico replaced the T's with copper tube and leak checked.

The new controller (XGS-600) installed for IG6 use a different voltage to pressure conversion than the previous models. This causes a discrepancy between values in EPICS and the value displayed on the controller. An e-fault has been submitted.
