The complete AeroElectric-List FAQ including these Usage Guidelines can be found at the following URL: http://www.matronics.com/FAQs/AeroElectric-List.FAQ.html Thank you, Matt Dralle Matronics Email List Administrator ****************************************************************************** AeroElectric-List Usage Guidelines ****************************************************************************** The following details the official Usage Guidelines for the AeroElectric-List. You are encouraged to read it carefully, and to abide by the rules therein. Failure to use the AeroElectric-List in the manner described below may result in the removal of the subscribers from the List. AeroElectric-List Policy Statement The purpose of the AeroElectric-List is to provide a forum of discussion for things related to this particular discussion group. The List's goals are to serve as an information resource to its members; to deliver high-quality content; to provide moral support; to foster camaraderie among its members; and to support safe operation. Reaching these goals requires the participation and cooperation of each and every member of the List. To this end, the following guidelines have been established: - Please keep all posts related to the List at some level. Do not submit posts concerning computer viruses, urban legends, random humor, long lost buddies' phone numbers, etc. etc. - THINK carefully before you write. Ask yourself if your post will be relevant to everyone. If you have to wonder about that, DON'T send it. - Remember that your post will be included for posterity in an archive that is growing in size at an extraordinary rate. Try to be concise and terse in your posts. Avoid overly wordy and lengthy posts and responses. - Keep your signature brief. Please include your name, email address, aircraft type/tail number, and geographic location. A short line about where you are in the building process is also nice. Avoid bulky signatures with character graphics; they consume unnecessary space in the archive. - DON'T post requests to the List for information when that info is easily obtainable from other widely available sources. Consult the web page or FAQ first. - If you want to respond to a post, DO keep the "Subject:" line of your response the same as that of the original post. This makes it easy to find threads in the archive. - When responding, NEVER quote the *entire* original post in your response. DO use lines from the original post to help "tune in" the reader to the topic at hand, but be selective. The impact that quoting the entire original post has on the size of the archive can not be overstated! - When the poster asks you to respond to him/her personally, DO NOT then go ahead and reply to the List. Be aware that clicking the "reply" button on your mail package does not necessarily send your response to the original poster. You might have to actively address your response with the original poster's email address. - DO NOT use the List to respond to a post unless you have something to add that is relevant and has a broad appeal. "Way to go!", "I agree", and "Congratulations" are all responses that are better sent to the original poster directly, rather than to the List at large. - When responding to others' posts, avoid the feeling that you need to comment on every last point in their posts, unless you can truly contribute something valuable. - Feel free to disagree with other viewpoints, BUT keep your tone polite and respectful. Don't make snide comments, personally attack other listers, or take the moral high ground on an obviously controversial issue. This will only cause a pointless debate that will hurt feelings, waste bandwidth and resolve nothing. - Occasional posts by vendors or individuals who are regularly subscribed to a given List are considered acceptable. Posts by List members promoting their respective products or items for sale should be of a friendly, informal nature, and should not resemble a typical SPAM message. The List isn't about commercialism, but is about sharing information and knowledge. This applies to everyone, including those who provide products to the entire community. Informal presentation and moderation should be the operatives with respect to advertising on the Lists. ------- [This is an automated posting.] do not archive ________________________________ Message 2 _____________________________________ Time: 11:35:00 AM PST US Subject: AeroElectric-List: Re: Fuel System Manager From: "user9253" I am not necessarily recommending dual relay control of wing tank valves. But I have attached a dual relay option. If automatic pumping from one tank is lost due to relay failure, then automatic pumping can continue from the other tank. But relays rarely fail. A disadvantage of two relays is more complexity. Kudos to Eric for designing a low fuel flashing warning light. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=516902#516902 Attachments: http://forums.matronics.com//files/valve_relay_2_100.png ________________________________ Message 3 _____________________________________ Time: 01:31:42 PM PST US Subject: AeroElectric-List: Re: Fuel System Manager From: "911pete" Joe If I want to prevent overfilling/venting the tank in manual (middle position) could we get 24v from the upper level sensor to the middle pole of the upper part of the selector switch.

Why not just use a 2 position switch, OFF and AUTOMATIC? Another option is to install a third level switch. Put it into the main tank vent. If fuel ever gets that high, either from operator error or from equipment malfunction, then it would turn on the red flashing alarm light. It would be easy to add that feature to Eric's circuit board. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=516905#516905 ________________________________ Message 6 _____________________________________ Time: 04:00:45 PM PST US Subject: AeroElectric-List: Re: Fuel System Manager From: "911pete" No I like it the way it is. One reason to be able to stop it is when taxing in if you shut down when the fuel is somewhere between the sensors the main tank wont be full. Then you have to climb up on top to fill it by hand. Using manual on the ground allows you to top off the main tank. By stopping it with the high level sensor you dont risk dumping fuel in the ground.
