| Subject: | Visio or IntelliCAD? |
--> AeroElectric-List message posted by: Mickey Coggins <mick-matronics@rv8.ch>
Hi,
I'm looking at drawing my electrical system, and
starting with Z13. I'm quite familiar
with Visio, but I don't have any of the needed
symbols. This seems strange, I know, but I've
never done electrical drawings before. Perhaps
they are on the CDs, but I can't find them.
I also installed IntelliCAD, but I'm not sure my
brain is ready to learn yet another drawing application.
Anything more complicated than the original MacDraw gets
me real confused! :-) IntelliCAD looks like massive
overkill for a schematic like this.
Has anyone already re-drawn Z13 or any of the
other AeroElectric Connection drawings with Visio,
so I don't have to reinvent the wheel?
Barring that, can anyone recommend a *simple* drawing
application that can manipulate .dwg files?
Thanks,
Mickey

Hi Mickey,
Since you already know Visio, I would suggest you use it. I use Visio
for my wiring diagrams, it is the perfect application for this type of
drawing. No, there aren't any Visio symbols/shapes on the CD, I'm
afraid you have to come up with your own.
Bob; This Visio shape topic seems to be a recurring thing, perhaps we
should start submitting our shapes to your for archival on the CD??
For any drawing that requires scale, precision, or dimensioning; I would
use one of the CAD programs (I use IntelliCAD).

Due to an excess of laziness, I just bought a new BC100-1 battery from B&C
to replace the 8 year old one that finally died. I cannot find a 120 volts
AC clock to make your battery reserve tester and I would like to start your
test plan. I will be rewiring my RV 6A per Z13 (replacing the VFR panel
with an very competent IFR panel) and plan to follow your instruction to
replace the battery when at 0.5 reserve capacity. Do you sell a kit to
make the tester that includes the clock?
Thanks

I have both AutoCAD and Visio. Visio is able to import a large number
of other formats, including DXF.
I will be doing my wiring design schematics in Visio and, as an
experiment, just tried to do an export/import of drawing Z-13. It
definitely works. Unfortunately, it imports as a single large group.
To use the symbols individually, one would have to ungroup them in Visio
or export the desired symbols individually from AutoCAD. My version of
Visio (4.0b) is fairly old and will not ungroup the entire drawing
(something about running out of memory). If you have a later version of
Visio (that might be able to ungroup the entire drawing), I would be
happy to translate the entire drawing to DXF and email it (them) to you
(or post them on the Matronics site if I can figure it out).
Otherwise, you can wait until I get to my wiring and I will give you
whatever symbols I use :-) .

You need to deduce the propagation mode for the noise. Radiated
magnetic or conducted electric (or both). Run gyro from 12 lantern
battery and see if noise goes totally away. If so, then the noise
filter described at
http://www.aeroelectric.com/articles/filter/filter.html
If the noise is still there, you'll need to fabricate a magnetic
shield from a strip of galvanized flashing metal . . . width equals
depth of instrument from rear of panel, length should be long enough
to wrap around the instrument about 3 times. Hold in place with
several bands of cable lace or some long, skinny tye-wraps.

I am mystified by the connections you cited. My data

and the PM1000II Intercom:
http://www.aeroelectric.com/Installation_Data/PM1000II_A.pdf

Hi David
I had the same problem with the same T&B. I talked ACS into taking it
back even though I had had it for 7 months. My argument was that I had
no way of knowing it was defective until I electrified the panel and
radios. I exchanged it for a more expensive quiet one.

<snip>
I am mystified by this romance with Cat5 computer cable for
use in airplanes. One of many experiences during my first visit to
OSH in '86 prompted me to begin working on the 'Connection . . .
. . . I saw a beautiful Long-Ez wired with a liberal sprinkle
of zip cord, and an assortment of automotive and house wire
held together with plastic electrical tape and "Plastigrip"
terminals and splices.
Premier has a LOT of 24AWG airframe wire in it and the folks
who put it together and maintain this airplane in the field
are less than enthusiastic about it. Even with 19-strand
lay-up (which Cat-5 is not), the stuff is much more prone to
handling and endurance issues than 22AWG.
Just 'cause the trim actuator comes with 24AWG wires in no
way commits one to perpetuate the design error by extending
the conductors with the same size wire, much less with a
non-recommendable material. 22759/16-22 is a VERY fine wire
for this application and you're going to need a bunch of it
anyhow for avionics and instrumentation tasks . . .
If you wouldn't run your Lycoming with Pennzoil, or
re-juice your flooded battery with tap water, why
would you wire your trim actuator with glorified door-bell
wire?

Hi Randy,
Thanks for posting your wiring diagrams.
They are Beautiful!
I will be pondering over them to glean what I can for my project.
On your Power Distribution Schematic you show your battery cables twisted.
Reason?
One small thing I noticed on the Power Distribution page. Looks like the
symbol for the battery should be 180 degrees ... long line positive and
short negative ... yes?
Thanks again,
Don B.

Depends on what you call "benefits" . . .
Obviously, RG-58 has a reasonably successful
history that goes back 60 years or more
and there are hundreds of miles of the stuff
still flying.
It's not going to fail to function.

Is this wiring diagram available to all? If so, where can I download it,
please?
Thanks,
AI Nut

I used the S251D479 filter/capacitor (fromB&C) after testing per Bob`s intructions.
The noise is reduced (ATC is happier) and I can`t hear it at all at altitude.
There is a snapping noise (independant of volume on the com.) and I guess
I`ll have to live with it as my wing tip light assemblies are rivetted. I think
I`ll make a couple of those Radio Shack filters as in a previous thread and
experiment?
Thanks again Bob. The whooping noise doesn`t aggravate anymore.

Just for the record, I have no plans to use this wire. Was just "discussing"
what I saw since others had seemingly expressed an interest. And I was
curious. :-)

Understand. Wasn't picking on you . . . this thread pops up
from time to time. It flew through the list about a year
ago as I recall. It almost always starts when someone is
wanting to extend the 24AWG wires on a RayAllen servo
with more 24AWG . . . or doesn't want to bundle their
own conductors.

Al,

For those of you with the interest, I posted all the wiring diagrams for my
F1 Rocket on my web site today. You can get to them off of the F1 Rocket
Project page. You can view them as .PDF files using Adobe Acrobat.
Perhaps you'll find them helpful. I don't have them all there yet as I am
still undecided on my EFIS and avionics packages.
Let me know if you see something that looks like it will let all the smoke
out of the wires!!
Regards,

Bob, I long ago committed to avoiding any PVC insulation anywhere in my
airplane (that I could control), and AFAIK even the plenum-grade Cat-5
has a type of PVC (irradiated, I think?) that, although somewhat more
fire retardant, is still not nearly as good as Tefzel...
My response was simply to state that Cat-5 is available in stranded as
well as solid (someone said earlier not to use Cat-5 because it was
solid), and why one might be better than the other in its intended
application... and that the mentioned "Cat5-superior" cable was not
likely superior because it was stranded, but because it was probably
Cat-5e (or even Cat6).
By the way, stranded UTP cable is still fairly easy to kink, certainly
much more so than 22759/Tefzel-insulated wire... I've got 12-ft runs
down a duct through Teflon tubing, and pulling Tefzel through it is
slicker than.... well, slicker than UTP anyway!
