No, the output of an LR3C is intended to directly drive the field winding of an alternator and it expects to see a nearly instantaneous response to TINY changes of DC voltage. The LR3 output varies from as low as 1v in cruising flight with light loads on the alternator to some value just below bus voltage.

Frank RV7a IO360 -----Original Message----- From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectric-list-server@matronics.com] On Behalf Of DEAN PSIROPOULOS Sent: Thursday, November 08, 2007 10:15 PM Subject: AeroElectric-List: Runaway trim --> Frank is correct: The folks at the Portland RVators did some testing on the runaway trim issue and confirmed this. While full up or down trim is difficult to counter-act when the aircraft is flying at high speed, simply throttling back and slowing down restores sufficient control authority to the pilot that a safe landing can be made. One thing I have not heard mentioned is elevator trim twitchiness in the RV aircraft. I had heard some folks mention that there is too much (electric) trim twitchiness at high speed and, trim does not respond fast enough when the aircraft is flying slow in the pattern. So....I purchased a trim control module from F-1 Rocket Boy to solve this (perceived) problem. I have a micro switch that opens when the flaps are down to send a signal to the trim control module to change the trim motor speed. One of the design features of this unit is that it has a runaway trim sensing feature built in. If the trim button is held for more than 5 seconds (ie. a trim wire shorted to ground), the trim control module assumes a runaway condition and shuts off the trim motor. Cycling power returns the unit to normal operating condition. Does anyone on the list use one of these trim control modules? Is it worth the time and effort I had to put into wiring it into my system (the price was reasonable)? And lastly, has it been reliable and does it always work as advertised? Since the airplane hasn't flown yet I'd like to know what to expect. Thanks.

No, the output of an LR3 is linear DC voltage intended to drive the field winding of an alternator at up to 3 Amps; it expects to see a nearly instantaneous response to TINY changes of DC voltage. The LR3 output varies from as low as 1v in cruising flight with light loads on the alternator to some max value just below bus voltage. An internally regulated alternator expects a fully-on or fully-off command signal; not a 'throttled', variable DC level. Turning the input command off after the alternator comes alive has no effect on most alternators. For external regulation the field lead is brought out for connection to the regulator and has a diagram much like so: http://www.aeroelectric.com/Pictures/Schematics/External_Regulator.jpg . . . while the internally regulated machine looks like this: http://www.aeroelectric.com/Pictures/Schematics/Internal_Regulator.jpg There's LOTS of "stuff" in that box labeled "REG" that would totally bumfoozle an LR3 or any other external regulator. >Are the dimensions of the S701-1 the same as the stock Vans' master >contactor (ES 24115) (which I already have attached to my firewall)?

Subject: AeroElectric-List: 396/4 96 Audio revisited


Thanks for all postings on the subject.

I just re-reviewed the manuals and talked to Garmin. Also, I have gon e
through 196, 296 and 396.

To summarize on the AUDIO subject:< BR>
In aviation mode:

296 has terrain and obstructions, but no VOICE warnings

396 and 496 both have terrain and obstructions, as well as the following
VOICE warnings:

-Terrain
-Obstructio ns
-500 ft AGL
-Sink Rate 
-Traffic (if so equipped)

The available outputs for the above warnings (as well as for XM audi o) are:

1) Data cable (voice+ and voice- ; use only voice+ , if no t using the
Garmin loudspeaker; do not use voice- > ; inst > ead, the ground of the power
cable is used; voice- is meant for loud speakers > with no connection to the
unit.

The Data Cable output is mono , low > impedance, amplified (for loudspeaker)

The volume of the output can be > controlled.

Music (if XM music is available) is soft-muted durin g warnings


2) > 3.5 mm audio jack - stereo, line volume, higher impedance

Music > (if XM music is available) is soft-muted during warnings.

The > volume of the output can be controlled.


So, there is no diff erence > between 396 and 496 in terms of available audio
(be it warnings or m usic) > and there is no difference between the audio
available from the data cable > (voice+ to loudspeaker) and the audio output
(3.5 mm jack). The only difference > here is impedance, signal, and
mono/stereo. Volume is controllable i n > both cases and XM music is
soft-muted by the audio warnings. Volume controls > everything coming out as
audio [Terrain, Obstru > ctions > , 500 ft AGL, Sink Rate, Traffic (if so
equipped), XM audio].

In aviation > mode, Garmin does not encourage feeding the data+/- to the
panel bec ause > it is an amplified low impedance, mono output, intended for
speaker and > the signal carries the same info as the 3.5 mm audio jack.

Fina lly, the > audio can be fed to a switched/soft-muted input of the audio
panel o r intercom > (to be muted by any communication) or to a non-switched
input (to be > always audible). Problem is in the latter case, if there is XM
audio , it will > be always on during ATC communications.

How to feed the audio fr om the > 396/496 is a matter of personal preference;
there are advantages and disadvantages > with any approach; all taken into
consideration, my preference is > to use the 3.5 mm line audio and to feed it

Handled it by slowing down to the new trim speed, but now I'm building a faster, more powerful airplane and am looking for protection from a potentially more difficult situation. The TCW system sounds good but I have a TruTrak ADI Pilot II and was wondering if they are compatible and if there is any sense in which they would work against each other. Does anyone know how these two systems would work together? Does the TruTrak provide any protection from runaway trim itself, or would it be better to have both? Thanks and regards, Lee... ________________________________ Message 11 ____________________________________ Time: 10:11:47 PM PST US From: D Fritz Subject: Re: AeroElectric-List: New product announcement Bob, Does this unit allow independent control of multiple units?

Flame suit on. (If necessary) Gary; #1 Very kind of you to append the whole of today's digest messages to your reply. (see Matt's rules of conduct for use of these lists) #2 How considerate that you think Matt should fork out the mega $$$$$$ it costs to support/run/host these lists without any consideration from those who benefit from their existence. (You and me. Matt's not the one gaining here) #3 I, for one, appreciate the ease of use, and especially the freedom from clutter/adds that these lists provide. They are FAR easier to use and follow without all the annoying junk found on Yahoo. (your example alternate) #4 I'm not yet building (Falco F8L), but only presently lurking (with the occasional post) and gathering, what I consider to be, volumes of valuable knowledge. (and in my opinion some of the most progressive knowledge going. Between Bob Nuckolls, Stein Bruch, Eric Jones, and even sometimes gmcjetpilot, to name just a few of the knowledgeable souls on this list, how can you go wrong???) #5 The entertainment value alone is worth the token amount Matt requests of us each year. Heck he doesn't even specify how much, leaves it entirely up to you what you feel is fair. #6 When this list provides information or assistance to you which saves you time , $$, $time$, or damaged components, (more$$$$) maybe you should consider giving that money to Matt. #7 Maybe the cost of the electrical course you don't need to take because of subscribing to this list should be forwarded to Matt???? #8 Maybe the $$$ you save by not having to have someone else sort your electrical issues should be sent to Matt????? #9 Or maybe, just maybe, you should consider sending your token $10-$20-$30-$40-$?? like most others for one of the most valuable, convenient, informative lists going. Where else can you get Bob N's sage advice for so little??? Certainly not on Yahoo! Rant off. Matt, some of us do appreciate the format. Thank you so very much. The $$ is well worth it.
