<pre>With regards to adding the groud braid from SVX central 
BH-east to SVX central BH-west... 
 
The COT requests the following: 
 
	- we use as small a braid as possible 
 
	- watch for RTDs at 6 o'clock, which are taped or 
	  epoxied to the ID of the COT; suggest feeding the 
	  braid through at just above 6 o'clock 
 
	- if we decide to leave it in place, then 
	  we need to contact Dave Ambrose (ambrose@fnal.gov) 
	  and let him know so that he can do some tests. 
	  THIS HAS TO HAPPEN PRIOR TO CLOSING THE PLUGS SO 
	  THAT THEY HAVE A CHANCE TO ADDRESS ANY CHANGES IN 
	  THEIR NOISE THAT THIS MIGHT INDUCE.

<table border=0><td><tr><td bgcolor=#e0e030><pre>IMPORTANT MESSAGE FOR ALL PLUGGERS AND HELPERS. 
 
BECAUSE OF THE NOW DOCUMENTED CAEN FAILURES THE FOLLOWING RULES FOR 
CAEN OPERATION WILL BE IN EFFECT UNTIL FURTHER NOTICE.  THIS IS VERY 
IMPORTANT SO PLEASE TAKE THIS VERY SERIOUSLY. 
 
1.  THE POWER FOR ALL CAEN CRATES WILL REMAIN OFF AT ALL TIMES UNLESS  
THAT CRATE IS BEING USED TO PLUG OR TEST A WEDGE OR SUPPLY REPLACEMENT 
OR MAINTENANCE ACTIVITIES ARE IN PROGRESS.  
2.  ONLY ONE CRATE PER DETECTOR END AND ONE SUPPLY PER CRATE MAY BE 
ENABLED AND POWERED AT ONE TIME FOR A TOTAL OF TWO. 
3.  THE ENABLES ON ALL SUPPLIES SHOULD BE PULLED EXCEPT FOR THE SUPPLY 
TO BE POWERED. 
3.  ONE PERSON WILL MONITOR CONTINUOUSLY THE COOLING INTERLOCKS AND 
THE CAEN GUI FOR COOLING TRIPS AND/OR A GUI ALERT THAT A POWER SUPPLY  
IS IN AN ILLEGAL STATE. 
4.  IF A COOLING TRIP OCCURS, THE MONITOR PERSON WILL IMMEDIATELY NOTIFY 
THE BORE PERSONNEL OF SUCH AN EVENT AND PERSONALLY INSURE THAT THE 
THE AFFECTED PLUGGER TURNS OFF THE APPROPRIATE CAEN CRATE UNTIL THE 
COOLING TRIP IS CLEARED.  REMEMBER TO WAIT AT LEAST 10 MINUTES BEFORE 
TURNING A CAEN CRATE BACK ON AFTER IT HAS BEEN TURNED OFF. 
5.  IF A SUPPLY GOES INTO AN ILLEGAL STATE, THE PLUGGER MUST TURN THE 
OFFENDING SUPPLY OFF WITH THE GUI, TURN OFF THE CAEN CRATE, REMOVE  
THE ENABLE IF IT IS CONNECTED, AND DISCONNECT THE CABLES FROM THE POWER  
SUPPLY.  THEN THE CRATE MAY BE TURNED BACK ON PROVIDED THE 10 MINUTE 
WAITING PERIOD HAS ELAPSED. 
6.  REMINDER--WHEN THE WORK IS DONE TURN OFF THE CAEN CRATE AND PULL 
THE ENABLES. 
7.  MAKE A CAREFUL E-LOG ENTRY OF ALL CAEN USE ACTIVITY PARTICULARY 
ANY ABNORMAL EVENTS.

<pre>GUI is reporting about trips in layers 0-2, 4</pre>
<!-- Date: Fri May 18 23:46:54 2001 -->
<pre>THE POWER SUPPLY FOR SB0W4 SHOULD BE CHANGED. 
 
Instead of tripping on HV ch. 3  it is acting as a current  
limit at 65 uA max. 
 
Matt can not change it right now as all the spares are now used.

<pre>Evening Shift Summary: 
- Started at 7.30 pm, when we un-did the COT bag, matts in place, set-up etc,.. 
- Difficulties to have a stable running of our laptop computer. 
  Kerberos problems, solved with the phone helpline (Steve Nahn). 
- Started SB0W4, when quadlogs tripped repeatedly. 
- Problems with the power supply of SB0W4. WiB test anyway.

<pre>OFTM or orange cable problem on OFTM n. 0</pre>


<!-- Date: Sat May 19 05:11:29 2001 -->
<table border=0><td><tr><td bgcolor=#e0e030><pre>	What's up on the west: 
 
SB0W4--AVDD overvoltage on LIB does not inspire confidence that 
we should plug the wedge into this PS.  Discretion being the  
better part of valor, we move on to 
 
SB2W9--according to logs, this card has a broken FIB command  
cable.  No notes indicate this has been fixed.  Discretion, 
etc., we move on to 
 
SB0W11--L1 does not read back on initialization, but currents 
are OK, and R/O is fine.  The logs indicate that this  
behavior is known, but they say it should happen on L4 (?!) 
Card LIB'ed, WIB'ed, plugged, tested, tagged-out, RTV'ed, and 
finished. 
 
This completes the list of things we are supposed to plug. 
Will now test / RTV S7IN, S8IN, then inspect.

<pre>RTV'ed S8IN after successful test.  Could
not reseat S7IN.  Checked RTV's for final
check for most of the remaining SVX wedges.</pre>
