<p>Our cooldown interlocks had tripped, courtesy of the
site wide power outage, and cooling back down had to
wait until everything else was recovered so I started
this morning.<br>
This was quite the challenge as it appeared there were a
number of secondary problems. The buffer dewars return
valve, EV8210BP, failed to function. After some lengthy
and painstaking troubleshooting, what was first thought
to be an IOC issue turned out to be a damaged connector.
Once this was fixed we continued to have problems with
high return pressures to ESR. More troubleshooting led
us to failed pneumatic valves at ESR, again due to the
power outage. Thanks to the help of Chris Perry and
company this was remedied fairly quickly. A long day but
the Solenoid and Torus are back at 80K park.</p>
