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.

Not much of a concern until injector is setup. Additionally, still awaiting HCO. -Central Plug - Position is out. Not much of a concern until injector is setup.

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?

This isn't preventing HCO progress, but it is something odd that I found.

Rack IN02B22B is listed in SRM as part of the ILD destination, but it does not appear in the alarm handler and it has no associated trims in CED. Checked both Injector and ACC nodes and it does not appear under either.

Went out to the SB to take a peek. IN02B22 seems to be split into two separate racks in CED. It has the trims from IN02B22 and IN02B22A that are listed in the alarm handler and CED.
