we are pumping the watt can at this time

I silenced the diff pressure alarm on the suva system the tank level is low so the pump turn on and off

Data logger isn't. Looks like the network is down already. Preparing for power outage.

Cryo Saga: 
BA #1 compressor is down for the count. The soft starter seems to be the problem. We contacted Beams Cryo and they looked at it; said it would be awhile. The cryo coordinator (Alex Martinez) okayed us to valve into the Tev. They are warming up to 80K, so the gas will be dirty.

Problems with the wet engine:  it goes into runaway mode. I called Rich Schmitt and he will look into the matter.

There is a LN2 leak at the pressure building valve.

This has been warmed up and the leak is gone.

<pre>The wet engine is in control now, but no modifications were made.  At the appropriate time, I would like to shut off the wet for an hour or so and then watch the controller parameters when it is started. 
 
Changed the COT endplate alarm from separator pressure to end plate temperature.  Added logic to bump the water valve open if storage level falls below 0.7 inches.  It will revert to normal  
control when the level rises above 1.0 inches.</pre>

Mark Nylund called and said they found a 5 volt power supply with low voltage to the compressor controller; also they found a loose wire on the 24 volt side. So Jim and I started the compressor and isolated BA#1 from the ring. The compressor started okay but didn't sound too good. The adsorber is still valved in.

Notified Beams cryo coordinator that we have the compressor running and are stand-alone again. (Valved off the Tev headers)

TRIPS WERE CAUSED INADVERTANTLY BY R.L.S. WHILE WORKING ON THE CONTROLS FOR SVX/ISL.

<pre>In Silicon PLC logic, changed ISL VP1A pressure control selector, changed backup pump logic on SVX and ISL.  Asked JL to revise relevant iFIX buttons since the auto/manual commands weren't all getting set correctly in the PLC.  A test of the backup pump operation is needed.</pre>

<pre>The new COT cooling logic shut off the pump and cooling this morning after the power outage when the end plate temperature fell below 68.5F.  It restarted forty minutes later.  The purpose of the new logic was to prevent very low temperatures during power upsets.</pre>

<pre>BAD TACH CIRCUIT IN LOWER FAN PACK IN 2RR25C.   CURRENTLY HAVE IT BYPASSED IN 4MATION.   VISUAL INSPECTION SHOWS ALL FANS ARE RUNNING.  WILL REPLACE FAN PACK IN THE AM.</pre>

<pre>Delayed entry from this mornings power outage.   With the exception of the cryo compressor and the wet engine that has a mind of its own when Rich S. is not around, recovery from the power outage went quite well.   As pointed out above, silicon cooling did not handle the  transition well.   One nagging problem is that silicon racks could NOT be turned on until I cleared in 4mation the voltage out of range error message.   We need to find the cause of this and fix it.</pre>
