I have just been informed that PFM wants to have a full power
shutdown to Cory Hall, Saturday, Jan 20th. A calculation on
lost income and overtime will have to be made and turned
into Wil's office for reimbusement. An announcement will be
forthcoming.

>>> 'power' problem from bob -- Tue Jan 16 11:07:41 1990 <<<

There will be a power shutdown of Cory Hall this Saturday.
Robert Norman and I will be here @ 7:00 Am to power down
the lab. Robert Norman, Phill Guillory and Evan Stateler
will be here along with me to power up the lab.

The results of Saturday's ampere usage check of 
all known  microlab feed sources are as follow:

Loadcenter / Voltage  / Location    / Phase 1      2     3

Bus Duct Main-440V 3P   CY1  "      "     230    140   250
Panel B   220V 1P       oldlab		   60     60     X
Panel C   208V 3P       oldlab		    0	  30	30
Panel D   208V 3P	oldlab		   20	   0	20
Panel F   220V 1P       oldlab		   12     18     X
Panel G   440V 3P       oldlab	    	   25	  25    10

Furnas Load Center -440V 3P - Rm.546      130    135   125


Two panels in the oldlab were verified again this a.m. and
the #'s were substantially the same.


How does this look?

The labuser storage area in the hallway of the newlab
has a new light switch. Simply entering the room activates
a motion detector which turns on the light. The light then
turns off 1 minute after the room is vacated.

This allievates the problem with the original switch being
outside the room in a very inconvenient place.

In addition,  an electronic ballast and new flourescent lamps
were added.

P: Tylan tube10 ancillary equipment malfunctioning.
S: Tracing circuit revealed the 117Vac feed into a
   common junction box had a grounded neutral lead.
   Repaired ground and had Carl reset the cooling
   system.

(The parts necessary to provide a neutral conductor
 for the tylan10 chiller are now on order.)

The chiller for this system is DOWN. The tube is on city water
back-up for cooling. This will all be reassembled 2/28/90.

( The problem with the voltage on the neutral phase on the panel
 feeding this system is still there. This will also be worked on
 2/28/90 starting @ 6:15am.)

A faulty neutral lead on panel 14ln (cg-4) has shorted. This lead
is part of the original lab wiring and services the lights in
the chase. It is being worked on by Phill Guillory and power
is interrupted on the breaker associated with this circuit.

One of the transformers supplying power to some lights and equipment
in the lab has to be replaced. The work is currently being done,
thus lights in the hallway, red rooms and the old lab are out,
along with some machinery in the old lab.

The lab up for the rest of the equipment.

	I looked thru the lab to see what was turned off when they
turned off the power to the lights to check for a short in the system.

	The cpa is off as well as the cooling for the lams, as well
as the as200, the mech pump for the cssem and the N2 and O2 flow monitors
by the cssem. A few terminals were off but I could not find anything else.

>>> 'power' problem from phillip -- Thu Mar  1 13:47:00 1990 <<<

The DOFM electricians reconnected the power panels to the 
suspect transformer. The trouble  'cleared while tracing'.

If the transformer is defective, it is intermittently so.


The RF power supply of the CPA machine was found backfeeding
voltage. It has been unplugged for now.

>>> 'power' problem from phillip -- Thu Mar 15 09:54:52 1990 <<<

Repaired N.E.C. violation in CV1. This was accomplished by removing
an idle 4-plex and replacing it with a blankoff plate.  

>>> 'power' problem from bob -- Fri Mar 23 08:10:08 1990 <<<

There were 2 power glitches this am around 6:30 am. I noticed them
at home while showering so they were in the main utility grid. The
lab has been checked and 2 pieces of equipment were effected.
ptherm2 was alarming and the gartek lost it's cryo's. The gcaws
lamp remained up.

It is advisable to check over equipment while going through the lab
so we are assured we are up on everything for the weekend.

There is almost a 100% corespondance between generator startup
and a voltage drop (loss of a cycle) with a minimum voltage
of around 100 VAC measured in 524 Cory. We have not observed any
problems resulting in our computer equipment however. Thanks for keeping
the log. Before you discontinue record keeping though give the microlab
people a chance to comment.

thanks,

Tim Kaardo called re his visit tomorrow (9am):

He would like to look at the complete set of drawings of electrical
wiring of the bldg. (Wil has them)

He would like to have a copy of the floor maps, like the 4th floor
map we gave him.

He asked if Phil could work with him.

As it turns out, the electrical prints for the
building are kept in John Benasso's office. Eleta Cook 
has permissed us to use the prints, in accordance with
Mr. Kaarto's mission. 
 Tim will be back tomorrow @ 9:00 a.m. The first stop
we make will be to pick up prints in John's office.
We will be using them on the 5th floor in rm.546.
Hopefully, the roadblocks experienced today are
resolved.

Working with Tim Kaarto to plot the power future capabilities
of the microlab. 

Relamped the 480Vac panel in rm.546.
(Tim will be here again tomorrow.)

We need a Facilties Management Request issued for an estimate of
running power (3 phase, 480V) from a panel in Rm 408 to the rear
of the Microlab. They should contact Bob Hamilton in Rm. 406.

Fund #432427-67505 recording number TO06.

Thanks,
Bob

You had asked how much power the Microfabrication Laboratory
is using. The answer is....................................:

1. The newlab..........153.3  kW
2. The oldlab.......... 17.1  kW
---------------------------------
        total.......... 170.4 kW

This figure is an average as based on the BMI 3060 power meter
that was employed for the readings. The oldlab also reflects
no lpe furnaces running at the time. I would think a +/- factor
of some value should be added.
