Logentry Text:
We setup and tuned a new cascade PID that controls the Set Value for a PID. This is the first one like this that I've ever used. The valve is PV8522SR and now we have a cascade PID PV8522SR_Val loop.
This loop adjusts the pressure setpoint of the Cold return valve PV8522SR from the operating point of 1.3 atm to allow a small trickle flow from the Lead Reservoir to the Magnet Reservoir of the of the  Solenoid at steady state to 1.45 Atm during a recool/refill of the Solenoid.

Now all we need is a Trip... (hopefully not for a while...)
