CDS alarm status during CP1 fill
Note to Operators: During the CP1 fill (which starts daily at 10am) the CDS ALARM system shows RED because the LN2 Liquid Level Control Valve (LLCV) is ramped up to 100% open. The alarm system puts this channel into alarm when its value exceeds 50%. This alarm should clear within 1 minute of the end of the fill.

Following user feedback, the IFO range "7 segment LED" display on the CDS overview is now GREEN when H1 is in OBSERVE, and orange otherwise.
