BCM temperature control read back screen showed no commication for IBCAD00C. Investigated the temperature controller, the front display indicated an "OPEN". Swapped the thermocouple cables on the chassis, and temperature was down to 74 degrees F. Found that the GFCI was tripped off, tried resetting it and the unit tripped off again. Replaced the GFCI, the cavity temperature is slowly coming back to it's set point.

Southeast Linac JT valves for 2L06-2L13 were manually set to 3% less than their current position ahead of the Southeast Linac power outage. The JTs will be frozen during the outage so this was done to avoid overfilling.

2L05's JT was set to 1% less than its current position, as it has been observed to have high heat leak and goes empty much faster than the other cryomodules. 2L02-2L04 are warm.

Cryomodules will be refilled as necessary after the power outage.

Have tried this for a few different system/component combinations so far....

Diagnostic BCMs & IBC0L02
RF Cavities & 0L03-2
Cryomodules & 0L04

Produces the error show in Fig 1.

The error in Fig 3 was produced when trying to submit the Ops-PR in Fig 2. This error references the Group. Couldn't reproduce this one, but the error in Fig 1 is easily reproducible.

It appeared to be moved to the home position on 12/3. This is also the time when the injector power outage took place. I figured it may have been related. Talked to CIS SME about the alarm. With their permission, attempted to move it back to the 3mm position. Encountered a CCW limit fault when doing so. Tried to move it back to home and got a CW limit fault. Relayed this to the SME and was informed that this would be looked at during HCO of the device.

Shortly after hitting the CW limit (a position limit?), the aperture position VRD0IA1AbsPosR wiped itself out to zero.

Prior to me enabling and then disabling, it had been disabled since 2023. Every alarm under this node has HIHI/LOLO limits of 0, leaving them in constant major alarm. They all seem to be on and functional.

Is the intention to eventually set alarm limits for this? If not, I don't see much of a need to have this in the alarm handler even if it is permanently disabled.

As title says.

NA01B06 is listed under the ILD destination in SRM. Looking at CED, this rack contains no trims relevant to the injector, just West Arc quads and correctors.

In the alarm handler, it is not present under the Injector node only the ACC node.

The SegMask does not reference the Injector either. Not sure how it got pulled into SRM for ILD. Maybe it used to have injector-relevant trims on it?
