John, Chandra, Richard, Ken (electrician)

Yesterday we removed and replaced the pneumatic actuator on the LLCV of CP1 with an electronic actuator. Richard's group made a 24 to 12 V board. The liquid level rose to 99% during installation and then settled back to 92% through PID loop 16 hrs later. 

Plan is to R&R actuators at end stations next (CP 7 & 8).

Motivation is to R&R all eight actuators before power outage in June. Actuators do not change position when power is lost.
