[Dsg-halla_ecal] [New Logentry] Heaters restarted more fans installed all setpoints 290degC.

[Marc Mcmullen]

We are scheduled to receive the upgraded Omega process controller in early May. At that point the temperature from the bottom area of the heated volume will be in EPICS monitoring. The middle and top areas of the heated volume are already in EPICS.

Regards,
Marc

The heaters all turned off around 10:30AM. I went into the hall and found that one Omega for the front ambient temperatures was tripped (furthest left on the rack which I believe is monitoring the bottom front ambient temperature of the detector). All Omega process controllers had sepoints of 270degC and were far from reaching that so perhaps it was a transient or poor thermocouple connection. If it happens again, we will have to try to figure out what is causing it. I reset it and changed the setpoints on all three to 290degC. Temperatures have started to climb again.
