Are You UPSet ?
Luckily, my good client accepted my good advice to allow
me to do a service of four of his UPS units plotted at the corners of
his large North Carolina county. His thrifty nature chided me into doing
all in a single day at a nominal fee, "cuz I was just passin' thru
from Virginia." I honestly had slobbery visions of a gratis barbeque dinner topping off the day, as a dozen of his back-slapping crewmen
all joked about fishing, hunting, and loose expense accounts. Instead,
I was met by my familiar lunch partner with half a cold gas station calzone. The day was spent knee crawling and stretching
to record measurements. For the first two Best Ferrups UPS systems, dust
bunnies were the devil and a few volts calibrated ensured longevity. Tightened
bolts, metered temps and checked for alarms.
Two more units to go and I am on my way to surprise my wife in Jacksonville,
albeit the taste of she crab soup still lingered on my tongue. As my preventative
maintenance sessions are more than thorough, I apologize to my client for
my extensive use of his time as guide. He nods a humble appreciation for
my record keeping and seems to take my recommendations seriously. I hand
him a football size oval of plastic wrap which had somehow situated itself
over the main fan guard cooling the heatsink of a 10KVA unit.
"I guess that could have become a problem," he drawls.
"Yes," I agree, "Power systems like their cooling. I expect
this kind of crap to accumulate since ya'll have made this room storage
for files and ... starter fluid ... 2-cycle oil .... and what the Hell
is this? Propane tanks?"
"I guess we ought to do something about that," is murmured
under a thick mustache.
This is commonplace. Battery backup equipment is relegated to an electrical
room. That's OK, but that room is also home for some fat-daddy transformer
installed right after WWII. The room is hot, but access is restricted.
I'll take it! (My first apartment overlooked a swamp... it was smelly,
but secluded, and I loved it.)
Our Carolina gentleman, a director, has many other duties and he hands
me over to an older fellow who is still senior, and, therefore, first
in line to (WAIT FOR IT!) OVERTIME. We are at the county's west perimeter
and we are boxing to its east and lastly its south site. It was a perfect
line-up that will leave me 30 minutes south on I-95. After 15 minutes
of eating Chevy 1500 fumes I was deposited behind my new guide on a slather
clay road. We bounced over an old tobacco field to finally roll onto the
gravel pad spread beside the county's cell tower. It's time to work.
This Best Ferrups 4.3KVA is old. I mean FD series old, but the sucker
is still humming; and according to the senior maintenance man, it was
not a problem unit. Humming she was, as one fan was stuck tight. She was
hot enough to grill cheese (yes I was getting hungry again). "No
problem, I'm sure I have a 230V fan for her"......... no. I was scheduled
to inspect three 10KVA to 18KVA units, and I am unprepared. If this fan
is only dumping heat into the working unit, then there is no harm in yanking
one (1) lead. So that's how we left it. Cooler, but not in shape. I chuckle
as I note the wide calibration change I had to make, yet she hummed. So
tough: so dirty.
