11:23 To get more flow through the solenoid I put PV8522SCD back in PID mode (from Manual mode) with its original setpoint of 1.5atm and put PV8522SR in manual mode at 30% open, which will increase the lead reservoir pressure drive more flow through EV8612.

11:30  Also needed to increase the setpoint of PV8566S from 0.12 to 0.25 

Total flow to Hall B has dropped from 4.1g/s to 3.2g/s but the solenoid is warming faster as more is going through the magnet reservoir and not just through the lead reservoir and its return u-tube
