[Dsg-dc] DC Mixing Controls

[Brian Eng]

Hi Bob,

Sometime this morning we're going to restart the gas shed cRIO to deploy a new version of the code.

The main difference from the current code is to add a max pressure setpoint (currently defaulted to 100 psi) that will set the flow multiplier (normally 1.2 & 0.8 which is used to bounce between the low and and high pressure setpoints [60 & 80]) to zero. This will have the effect of (mostly) stopping flow from MFCs and allowing the pressure to bleed off through the TCUs.

One thing to keep in mind is that if this condition is met, the flow must manually be changed once the pressure drops below 100 psi.

Let me know if you have any questions or issues with this setup.

Thanks
