2L18 KCCU still zero

After swing shift bypassed 2L18, they were able to get the zone back into HV, but as RF on call pointed out, the cavity KCCUs have been zero. They are still zero almost 8 hours later. We have left the cavities bypassed with the zone in HV so RF can take a look when they are able. We should be able to bring it down without disrupting beam if needed. I think.
