Actually, the proposed AEC9024 is FOUR products in one box. During installation, the builder sets functionality by adding jumpers between the programming pins. This design philosophy allows us to produce four products on one assembly line and inventory only one device the four offerings and even lets a builder inventory one spare part for any of the four functions. Builders may choose to use the device in any one of the four tasks. Architecture figure Z9 illustrates use of the 9024 in three of the four functions. http://tinyurl.com/5wxzn7 It will be the first AEC product loaded on the B&C product line early next year. There's about a half dozen more that will follow on the heals of the 9024.

Jones" EDN of 23NOV1995 had an article entitled: "Assume nothing. Test everything." which was a small guide to troubleshooting philosophy (although aimed more at computers and high falutin designs but applicable to life in general). He (Jack Ganssle) taught some critical elements of troubleshooting that have helped me over the years. Allow me to share some of them them with you: 1) EVERYTHING YOU KNOW IS WRONG. I.e. Assume nothing. Is it really connected like you think? Are your measuring instrument working? Etc. To facilitate this process--> 2) Keep a notebook of what you are doing, what you suspect, random suspicions, sketches, details, notes for later improvements, hard-to-read numbers, EVERYTHING. When you review your notebook the next day, important clues will often jump out. 3) Start with an organized workbench with all tools at the ready. What are you going to need to test assumptions? 4) Ask for help. Don't be shy! Anybody can help by listening to your explanation...where the obvious might jump out.... Asking experts is how you'll learn, even if they don't have the answer. 5) Use the Internet. Hardly a day goes by without someone asking me a question and I reply (or would like to reply) "Let me Google that for you". Google has developed the ability to understand plain language questions. The value of searching the 'net cannot be overstated. And it will only get better. 6) Remember, most problems have simple answers. Think "Connectors" not Integrated Circuits. Think "Horses" not Zebras. We can all add tips to this list. -------- Eric M.

When you review your notebook the next day, important clues will often jump out. I should have followed that advice while doing industrial electrical troubleshooting (before retiring). I would take measurements without writing anything down, thinking that I would remember. But then later I could not remember what the conditions were while testing. Was that switch or that indicator light or that relay turned on or off? Then I would have to repeat the measurements. But if it was an intermittent problem, no measurements could be taken while the equipment was working properly. More time was wasted repeating tests then if I had taken the time to write notes. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=451169#451169 ________________________________ Message 12 ____________________________________ Time: 04:20:42 PM PST US Subject: Re: AeroElectric-List: Re: Low Voltage Annunciator From: John Tipton For a simple indication of Low Voltage: http://www.sparkbright.co.uk/sparkright-eclipse-battery-voltage-monitor.php John Sent from my iPad ----x--O--x---- > On 19 Dec 2015, at 03:19 pm, "Eric M.
