Scott MaNally stopped by and apologized for not getting in touch with
the Microlab sooner. He serviced the chiller on the roof and found
the problem. The recirc flow rate through the coils on our intake
air was throttled to low and the water in the chiller necame excessively
cold. FS-1, the controller that tripped, is designed to keep the bundle
in the chiller from freezing. Once the flow rate was increased, the water
temperature rose and the chiller seems to be wroking fine.

 Hi Bob
    The status of the McQuay chiller is Aladdin came out yesterday and found
that the first stage was low on freon and oil. The unit tripped out on low 
oil pressure. There was a bad micro switch for the compressor's oil heater 
this caused the loss of oil. The micro switch is being replaced and the 
micro lab presantly has full cooling capacity.
     Also the problem with the cooling tower was in no way related to the work 
completed by Aladdin.

mfm on O2 is not working so readout of use is impossible. This needs
to be serviced

>>> 'facilities' problem from evan -- Thu Feb  2 16:35:19 1989 <<<

problem: MFC on lab O2 failed.
cause: 324 op-amp failed on circuit board.
solution: replaced op-amp. re-calibrated MFC and re-installed.
          The wafer filter was also changed.
 O2 flowmeter is back online.

>>> 'facilities' problem from bob -- Wed Feb  8 10:38:11 1989 <<<

The recirc loop requires its filters to be changed. They are bypassed
at the moment and there is no urgency re: this

>>> 'facilities' problem from evan -- Wed Feb  8 17:06:21 1989 <<<

The seemingly excessive use of O2 was found to correspond to the running
of GATEOX5 on tylan6.  During step 35, it calls for 4 slpm of O2.  This
causes the house O2 flowmeter to jump from 4 to 42 SLPM.  It seems
possible that it might only be a misplaced decimal point.  I will
continue looking at this tomorrow.

A 4 (or 0.4 if decimal point is wrong) SLPM leak was found and repaired
in CV3 on the line to the heatpulse.

>>> 'facilities' problem from evan -- Thu Feb  9 08:40:51 1989 <<<

I checked the MFM on house O2 and found that the decimal point is correct
and that tylan6 GATEOX5 calling for 4SLPM of O2 raises the house consumption
over 40 SLPM!  I will be checking the tylan6 O2 MFC this morning.

>>> 'facilities' problem from phillip -- Thu Feb  9 14:48:00 1989 <<<

Concerning the recirc loop:
 A new 10-35 psi H20 regulator has arrived. This is the
one that is just before the 'filtrol' device. I will be
installing this  
in the early morning hours in the next week or so.

>>> 'facilities' problem from evan -- Thu Feb  9 14:41:38 1989 <<<

Problem: 10 times expected O2 use.
Cause: Missing decimal point on calibration unit.
Solution: I was fooled by a missing decimal point on the MFC calibration
unit.  Thus, the house MFM for O2 was mis-set to read 10X too high.
When phillip and I isolated the old lab O2, the resulting drop in flow
was actually caused by a tylan job shutting off O2.  This coinsidence
further led me to believe I was dealing with a leak.
The end result is that the tylan6 MFC was fine.  I repaired the decimal
point l.e.d., recalibrated the house O2 MFM, and all is back to normal.

The positive aspect of this adventure was finding and fixing a couple
of actual O2 leaks.  Phillip located and repaired a leaky valve to the
barrel reactor.  I replaced the heatpulse O2 line in CV3.

>>> 'facilities' problem from galewski -- Fri Feb 10 20:57:40 1989 <<<

Strong smoky smell occurs with regularity almost every night in the
lab.  Especially strong in VLSI area.  Quite uncomfortable.  Used to
think that alot of woodburning at night by people with fireplaces
but kind of reminds me know of the strong wiff I got by tylan 9
pumping down.  The rest of the building does not smell like that
so I think that maybe where our inlet is or something in the lab.

Replaced filters on the recirculation system.  The old ones were very dirty.

>>> 'facilities' problem from evan -- Mon Feb 13 17:09:13 1989 <<<

problem: low pressure on recirc makeup loop.
cause: improper filltrol action 
solution: system pressure was zero (actually under vacuum) due to lack
of make-up water. The filltrol bladder was pumped up with no result. The
regulator setting was varied, also with no effect.  It was discovered that
the filltrol valve was not allowing any water to pass.  The inlet pipe was
removed and a clogged screen filter was found.  This was blown clean and
replaced.  The bladder pressure and regulator pressure were varied to give
a 5 psi differential pressure.  These two variables were very interdependent
and further work must be done to find the optimal settings of each.  

The recirc water make-up system is operating.

>>> 'facilities' problem from phillip -- Wed Feb 15 12:23:07 1989 <<<

Set filltrol device to 12 psi bladder pressure.
Set make-up water pressure to 40 psi.

Status: R

The seems to be an interrelated problem between thr randex draining H2O and
the loss of lab pressure in the recirc system.  It seems that the make-up
rate is too low to replace the volume of H20 used by the randex in drain.
This allows a volume of air to become sucked into the line and causes the
lab pressure to drop to whatever the city pressure can deliver. This low
pressure to the lab appears as an excessive back pressure (as reported).
In any case, the alternate operating mode for the randex, using the drain
to achieve enough flow, only acts to increase the problem.  

The ultimate solution will need to either: 1) Increase the make-up ability
of the recirc loop, 2) provide an alternate source of H20 for the randex or
3) a combination of the above and/or change in operating precedures.

Since this problem affects many pieces of equipment and has been reoccuring,
a plan of action should be formulated ASAP.

Problem: Water flow meter not rotating.

Cause: IT looks like we are and have been having REC. water problems;
       there is a high back pressure on the return line. This is causing
       low water flow through the water flow meter.

Solution: I replace the protius water flow meter and it did not change the
          problem. There is about .75 GPM of supply water, but the back pressure          is so high it goes to nothing. To run the randex until this problem
          is repaired the supply water must be dumped down the "Drain" as noted
          on the water control knob. The randex is operational.

phillip and I concluded the there must be something else in the lab

had been made to the veeco in GC3.  He shut this source off and a new

As techs review the equipment dependency lists, all recirc H20 hookups
should be checked.

 I've completed changing the filters to supply fan # 102 for the Micro

 Also, when we change these filters there will be more dirt going to

The McQuay chiller on the roof is down on one of the two compressors. It 
is being worked on by Alladin.

>>> 'utilities' problem from evan -- Thu Jul  6 13:12:18 1989 <<<

The Alladin repairman has bypassed the failed component and both compressors
are on-line.  He will come back and install a replacement part when one is
acquired.  The lab temp should be cooler, but don't forget that we are in
the middle of another heat wave.

>>> 'utilities' problem from bob -- Mon Jul 10 10:44:02 1989 <<<

Alladin has completed the work on the McQuay chiller. A sensor had to be
replaced. The air conditioning is again functional and operating correctly.

>>> 'utilities' problem from bob -- Tue Jul 18 16:10:35 1989 <<<

The temperature of the CHWS (McQuay) is now 60F instead of the 
normal 45F. This effects the temperature of the lab and particularly
the red room as it has a large solar heat load. Cynthia has been called
and Alladin is being contacted on an emergency basis. For the time
being, the pg has been shut down. Alladin is instructed to stop by
the office and check in when they are here.

>>> 'utilities' problem from bob -- Thu Jul 20 09:06:33 1989 <<<

The chws appears to be working. The water temperature in the loop is less
than 40F, a desireable figure. Work was performed by Alladin on the McQuay
chiller however we have yet to get a report of what work was done. The
chws utilitie is up.

>>> 'utilities' problem from bob -- Fri Jul 21 10:50:21 1989 <<<

The chws has temp is over 70F and should be at 45. This is the water
used to air condition the lab. The McQuay chiller was found off
on all stages and I restored it by resetting HP1 and HP2 cut
out switches. It is running and an emergency call is in to
PFM.

>>> 'utilities' problem from bob -- Fri Jul 21 11:57:47 1989 <<<

The McQuay chiller had a set of belts slip off on one of its fans.
The cause is yet to be determined but this problem is unrelated to
our last set of problems. Scott is installing new belts and the chiller
should be running within the hour. Scott will also investigate why this
is occuring. He found a belt off 2 weeks ago and had a machinist come
out and check the pillow blocks and sheves on the fan. They checked 
out OK.
When more information is available it will be added to this file.
The chws system should be up shortly.

Recirc water will remain on bypass for the day and possibly part of 
tomorrow. The plumber has been called away on an emergency job 
(a 16" main broke on the hill) and cannot complete our job, 
valve exchange in recirc loop, until the emergency is taken care of.

>>> 'utilities' problem from bob -- Wed Jul 26 11:17:29 1989 <<<

A new water proof flow switch was installed in the microlab recirc
system. Upon completion the loop failed to start. An electrician found
corrosion on wiring associated with the motor contactor of the pump.
The wire nuts and crimp connections were replaced and the loop is now 
operational. 

The flow setter on the shunt loop-flow switch has been set
to 50% reducing the inlet pressure by 3-4 lbs. A further
reduction (ie an increase in working presure) in inlet
presssure will be sougght by reducing the Fill-trol tank
pressure to 5 psi from its current 12 psi.

While work was being done on the PG A/C the yellow lights
switch in the PG room ceased to work.  This will be repaired 
ASAP.

The recirc system has been checked after our reported flood and 
found to be in good working order. It has sufficient makeup to
survive a fair rate of loss.

I have checked the DI holding tank, it is full. I found the
DI shack fully open. Is there a reason for that, Scott?
Bob found it the same way a few days ago.

>>> 'utilities' problem from bob -- Thu Sep 14 09:01:46 1989 <<<

The air pressure to the Microlab is less than our required 85 psi.
Currently it is 75 psi causing alarms on the CPA. This message will
be sent to Eleta for action by the Stationary Eng.

In addition the input filters were checked and although damp, 
they appear to be in excellent condition. The dampness has been
caused by the filter/dryer in the basement having been off
for an unknown reason. It is back on and the lab lines
should dry with time. Problems with aluminum bodied
solenoids such as the Humphrey's used on gate valve often
follow when the air is no sufficiently dried due to the
reaction of their aluminum bodies with moisture requiring
replacement.

In addition to the lower than normal air pressure (75 instead of 85-90)
I also found the air dryer off in the basement. I restarted it as
it is absolutely necessary for the Microlab equipment. The stationary 
engineer should be notified it was again found off. Eleta has been
notified.

>>> 'utilities' problem from bob -- Thu Sep 14 11:28:17 1989 <<<

The air dryer is shutting itself down due to the failure of 
the cooling fan on the refrigeration compressor's heat 
exchanger. This problem was investigated by Ed Wong of PFM 
who will report it to the refrigeration specialists. This 
report should be followed up as the air dryer is of great 
importance to the Microlab and it's equipment.

The air pressure has been set to 85 psi on the supply
regulator, enough for our needs. Eleta will be cc'd this
report so the AD-15 service can be tracked.

Besides problems from the motor generator in the basement,
Fred Archibald and Ken Lutz have both reported the loss of
electricity for up to a few cycles. They believe that the
cogen plant put on-line by the University fails to provide
fully uninterruptible power when it switches to and from
PG&E as a source. This problem are being investigated by Wil
Zeilinger.

The air dryer in the basement has been fixed.
The air is up and adjusted to 90 psi.

>>> 'utilities' problem from bob -- Fri Oct  6 07:22:09 1989 <<<

The air dryer in the basement is again not functioning. This is
evidenced by the oil and water now appearing in our air lines.
I walked down to the basement and found the unit off with no
power supplied. This message will be cc'd to Eleta and stateng
(Scott) for service.

>>> 'utilities' problem from bob -- Fri Oct  6 09:56:30 1989 <<<

The air dryer in the basement has been checked by our Stationary
Eng. Scott found power to the unit and therefore there is a problem
within the unit. He has turned in an "A" tag for expedient service.

>>> 'utilities' problem from bob -- Mon Oct  9 14:21:29 1989 <<<

The air dryer was repaired, it had a blown fuse in the control panel.
Reason: Unknown
The dryer has been checked on several occasions and appears to be working
fine.

A bridge of the air lines has been run between GL-4 (new lab) and
a tap above the ceiling of the lberg furnaces. Both terminations
have been labeled with their destinations and the old lab is now
being fed from the new lab. The old lab feed is now valved off.

>>> 'utilities' problem from bob -- Wed Oct 18 09:03:32 1989 <<<

The air dryer is again down in the basement. The S.E. has been informed as well
as Eleta and we are awaiting repiars.

A Black Max N2 gun was installed between tylan banks 2 & 3 and at bank 1.
These are N2 guns not anti-static guns.  Each gun pressure can be set 
individually, and are now set at 40 PSI.  They are ready for use.

Phone problem :

the -2796 line is continuously tied up -
I checked all phones in the lab - but none were
off the hook. The office was dark  ( so no one was using it in there )

Probably a quick fix somewhere - just frustrating not being
able to call out

A request to OPR (Office of Physical Resources) aka PFM, aka DOFM, 
aka Physical Plant, aka Grounds and Buildings, has been made to
have them service our spare recirc system pump. Jim Wilson of the
plumbing shop is in touch with the Maintenance Machinists. They
will work out who will take charge of this repair.
An update to this report is pending Jim's return phone call.

# new LOX cylinders were installed this afternoon in the rear of
Cory Hall. These came from our new vendor Airco, the successor

The old lab air feed from the west side of the building has been
valved back on. This feeds the lab from both the west and the 
east building risers, our normal mode. 
This valve had been closed during the construction on the first
floor. Operations are better with this feed open.

>>> 'utilities' problem from bob -- Tue Feb 27 09:16:57 1990 <<<

The lab suffered a loss of air pressure and also a loss of
N2 back up pressure this am. The likely cause was the loss of
air pressure due to a shutdown of the compressors in the basement
accompanied by the backfeeding of N2 to the rest of the building.

An unscheduled shutdown is the likely cause!

A check valve will be ordered and added to the old lab air
feed. This will prevent backfeeding the building in the
future.

Eleta is looking into who shut off the air.

>>> 'utilities' problem from phillip -- Mon Mar  5 14:20:02 1990 <<<

P: Failed ICW check valve allowing H2o to flow thru
   the lab back into bldg supply.
S: Replaced failed plast-o-matic valve with spring loaded
   brass check valve in the aux. supply line. The ICW
   is back on line.

>>> 'utilities' problem from phillip -- Thu Mar  8 08:36:04 1990 <<<

Check valves have been added to the pneumatic line 
in the oldlab.
This will prevent n2 from back feeding the rest of the
building when the air compressors go down.

>>> 'utilities' problem from phillip -- Thu Mar  8 09:17:56 1990 <<<

P: Microlab supply air is excessive in volume.
   Also, the temperature is low.

 Eleta, please report this to John Tusting/DOFM.
thank you

John T. swapped, to their correct positions, a pilot control line
and a delivery control line (both steam).
 There is remaining a case of trouble on the steam valve itself
that John referred to the steamfitters.

There is a report of low oxygen pressure. A check of the LOX in
