Today I emptied the Solenoid Magnet Reservoir and completed the installation of the upper heater plate on RV8670. This included setting the PPRV to 2.0 atm (absolute) 
I used a calibrated local gage which read 14.6 psig to set the spring compression. I then checked the relief valve with pressure source to magnet reservoir through EV8611CD with all return valves closed and the relief lifted at 2.09 atm indicated by pressure transducer PT8670. I then backed off the springs by 2 turns and retested. and got 2.03atm. I double nutted the relief valve and added the do not adjust tag. Tomorrow the lower heater plate will be installed.

The magnet is now filling with a slightly different set of PID's that will be further improved when we have the heaters fully instrumented. These should allow automatic recover after a fast dump.
