Hi Chris, Please reset CEV6711C back to 27 g/s. It has been set at 2.8 g/s since about 4:30 pm yesterday, Friday. CEV6711C is the Cryo groups flow limit for Hall C, it regulates how much 4K Cryo allows Hall C to take. If you refuse change the limit back we will have no choice but to remove the limit from our controls. Regards, Mike
