Subject: | Re: Question about an Aux Alternator |
"With Z-13, you leave the SD-8 off until needed when
it is determined that the main alternator is off line
(lv light on). You drop to e-bus loads, open battery
contactor, turn SD-8 on and continue to airport of
intended destination. If the SD-8 is not overloaded,
the lv warning light will go back out."
With regards to the SD-8 and the lv light, Z-13 has a single lv light on the diagram.
The descripton for the PV/OV crows foot kit available from B and C states
that "The PM/OV was designed to give over voltage protection to the permanet
magnet alternator. The yellow light will annunciate if the alternator switch
is left off, or the crowbar over voltage protection has been tripped. "
So, will the single lv light depicted on Z-13 light if either the main alt or the
SD-8 are off line?
If the SD-8 has its own unique lv light as described on the B and C site, does
it light if the aux alt selection switch is OFF? Or, does it only light if the
aux alt selector switch is ON AND the SD-8 is off line? If the first case is
true, during normal operation, the aux lv light will alway remain lit which would
not be an ideal situation.
Thanks

I'm sorry, that is a contradiction in terms. I also know what you said is the
commonly held belief.

I don't deny that anyone is willing to work hard to advance themselves. That's
natural state, not something that's a special right to people that live in this
country or theirs.

Working hard isn't enough. People need the freedom to keep as much as they earn
as
possible and to keep government out of their lives. China is succeeding despite
not
having that prerequisite due to their currency policies. In theory, we are allowing
these imbalances to occur because in the long run economic prosperity will reform
their government. Governments reform in that situation only when not doing so will
hurt their economy enough that they have to worry about revolt from their people.
The chinese government is getting a free ride and has no incentive to change under
the current situation.
And no, I don't consider our current economy capitalistic either under my own
restraints I mentioned above. That's a problem, not something for other countries
to emulate.
You can also turn this around and consider it a reflection of great immorality
of our
elected representatives for not pushing harder for currency reform. This policy
just
doesn't hurt our country it will deny freedom to Chinese citizens for a longer
period of time (assuming china's citizen's ever achieve it).
The prosperity in China's city's is not reflected in china as a whole. There's
abject
poverty for anyone not in the party in rural china.

Ummm...don't tell la raza that. lol. As far as dominating us, I don't buy it.
America only loses in the presence of an unlevel playing field. Once this goes
on
long enough to hurt our economy enough china's will lose it's main market.
c'ya,

How much time have you spent in China?
This weekend I met up with a friend who flies for Cathay Pacific, based in Hong
Kong. Many of his blocks of flights have overnights in various cities in China,
so he has observed China first hand for many years. He reports that while
the government is still communist, the Chinese economy is very capitalist. The
working people want all the stuff that we in the west have, and they are willing
to work long days, six days a week to get it. Their economy is growing
very rapidly as a result, and the standard of living of many people in the cities
is improving very rapidly. He recommends that our children learn Mandarin,
rather than Spanish or French. He believes that China's economy will eventually
dominate that of the western countries.

In the following schematic, the entire circuit is 12VDC except for the
Timer Relay Contact at the bottom which is 120VAC.
How do I size the diodes for the 12 V portions? for the the timer relay,
switching 120 VAC, with a 12VDC coil?
/
+ ---+---o o---+------+----------+
| S1 | | |
| | [Relay1] |> | <-Relay
| | | | Contact
| | | +-------+
| / | | | |
+---o o---+--|<--+ | [Motor]
Park D1 | | |
| +---|<--+
| D2 |
| S2 |
Gnd -------------------+---o->o---+--+---> Trigger
| | Signal
Timer Relay Contact-> '-> | | to timer
| |
+------+
How it works: When in the park position, the park switch
and S1 are both open. Pressing S1 energizes Relay 1, its
contact closes, the motor moves and the park switch closes,
keeping Relay1 energized until the mechanism moves back
to park. When the mechanism reaches the S2 position, S2
opens and removes the (-) trigger signal to the timer.
After 30 seconds, the timer relay de-energizes and the
relay contact closes. That causes the motor to run again,
moving away from the S2 position and closing S2. That
sends the (-) trigger signal to the timer which energizes
the timer relay. The mechanism returns to the park position,
which opens the park switch and de-energizes Relay1, and the
motor stops. Diode D1 protects the switches against the
inductive spike created when power is removed from Relay1;
D2 protects against the inductive spike from the motor
when power is removed from it. The timer relay coil should
also have a diode placed across it, wired the same polarity
as the other diodes (banded end connected to the + side).

Subject: | Wire specifications |
I am building a Dream Aircraft Tundra (4 place aluminum bushplane) and
am confused as to what wire to buy.
Most wire comparisons list TKT as being the only thing that is wonderful.
However, most companies seem to be selling Tefzel for homebuilt aircraft.
Is there a convenient source of reasonable lengths of TKT wire ?
Thanks !

Why do you want TKT? M22759 Tefzel has been the wire
of choice in Wichita for tens of thousands of airplanes
for about 25 years.

Subject: | Re: Schematic drawing software |
As suggested, I have purchased a copy of TurboCAD Deluxe 10.2 on Ebay and it does
a fine job of opening Bob's .dwg files.
Unfortunately, I have no CAD experience, and don't know how to use TurboCAD. The
TurboCAD interface has an Internet link for Tutorials:
http://www.turbocad.com/tutorials
Unfortunately that web page doesn't exist. I have searched the IMSI website for
tutorials, but cannot find anything. I note that there is a Tutorial folder in
the TurboCAD folder that loaded with the program. But w/o the tutorial narrative,
I don't know what to do with these sample drawing files.
Does anyone know where I can find the tutorial files that (apparently) used to
be available from the TurboCAD people? If I could just find them once, I could
use the FireFox Scrapbook utility to make my own copy of the tutorial files.
Thank for any help you can give me.
