WBSC ISI models restarted to capture final edits to SUSPOINT Euler Calcs

Changes were required to accommodate multiple suspensions on the ISI. This was a top level change and ITMY already had this edit so was not restarted. BS ITMX ETMX & ETMY all restarted without issue. safe, OBSERVE & down (BS) SDFs updated.

Still need to populate CAL filters and the CART2EUL matrices.

Manually over-filled CP3 at 20:20 utc

1/2 open LLCV bypass valve, and the exhaust bypass valve fully open.

Flow was noted after 10 minutes and 10 seconds, closed LLCV valve, and 3 minutes later the exhaust bypass valve was closed.

Next over-fill on Saturday, March 19th before 23:00 utc.

The manual valve setting was increased from 15 to 18% to help compensate for this increased boiloff.

Y-arm TCS laser reporting flow alarm

I notice that the TCS Y laser is off and reporting a flow alarm. The flow meter shows that the chiller is currently running. I don't think this laser was in use but was running and it would be better not to leave it in this alarm state. Either the power supply should be turned off if the laser is not needed, or it should be reset by turning the controller key on/off and pressing the gate button on the controller.

An instruction on how to restart TCS chiller and controller box can be found here.

Both TCSX and TCSY chillers were found to be tripped with an error messgage 'Low Temp'. I have power cycled the two units. And cycled the key on the X and Y CO2 laser controllers. They are now back up and functioning.

alastair.heptonstall@LIGO.ORG - 12:04, Wednesday 16 March 2016 (26102)

Thanks Kiwamu. The LOW TEMP warning will almost certainly have occured because the DAC at some point has been restarted and caused a zero voltage out to the chillers. This problem is meant to be getting fixed soon with an electronics fix.

It looks like the lasers are now ready to lase, and now you've reset the warnings with the key to get them running you probably just need to press the gate (on/off) button on the front of the controller. I'm not sure you need them right now though.
