don't change anything until it is stable and you thought about it carefully. The system was totally out of control, check the dataviewer!.
So there is no way to make an estimate for the values as you have no equilibrium!! That takes several hours after ANY change to the system, like rebooting the crate or turning on a temp control loop.
Remember: time constants are several hours!
So be patient and wait until tomorrow or late tonight before you make estimates and changes. Both temperatures are NOT close to their original setpoint and largely fluctuating.
RCAV is at 34.8 instead of 35 and ACAV changed from 37.1 to 37.45 within the last hours.
So no way to make the right adjustments right now, as your laser SLOWDC value does not reflect the actual temperature of the chamber.
Changed it back to the original settings (37.3) as those were working over several days before the system stopped working properly...
I adjust SLOWDC to see what value to lock each cavity.
For ACAV I adjust SLOWDC so that VCOMON fluctuates around 0 and record the value of SLOWDC
I adjust ACAV_SETPT to see how the DC changes (in RED), it seems I have to reduce the ACAV_SETPT
SLOWDC -0.1118 ->-0.1151 -0.1051
SETPT 37.3 -> 37.35 35
Now, ACAV_SETPT is changed to 37.15, but ACAV_TEMPAVG goes up (after 30mins.) to ~37.43 (from 37.3).
The variance from ACAV's 4 temp sensors are getting larger.
Frank, did you remotely change ACAV_SETPT back to 37.3? I came back and it was back to 37.3.
