In my (admittedly quick) look around the PLC code of the distribution box none of the conditions are being triggered. There are 3 tags that can trigger an interlock: a DT from the torus, a DT from the solenoid and LL from the torus. </div>

I'd have to dig into the code some more to figure out the exact logic behind each of those. Let me know if you still need that.</div>

I can say that right now PV8563C is in normal mode and being controlled by TD8513S and PV8563W in normal mode controlled by PT8563.</div>

We would like to have more information about about the interlocks on the Cooldown/Warmup valves PV8563C and PV8563W.</div>

<br>
When I was leaving the hall this afternoon to go to a meeting Dontre mentioned that there might be some issues with the PID, have these been worked out or is there still something I should look into?<br>

Thanks<br>
