 |
|
I'm looking some feedback on my electrical system, based on Z-19RB. You can get the pdf here:
http://www.mistakeproofing.net/transfer/N202SH-Z-19RB.pdf
This is a retrofit in my 20 year old composite Quickie Q-200. I do a lot of day VFR cross country with this plane and do some cross country racing. Since I am converting to "all electric" I would be interested in your thoughts about my proposed system.
Besides the Dynon FlightDEK 180 the biggest change is the conversion to electronic fuel injection. I am using the EC-3 controller from Real World Solutions (RWS). You can see more about the controller here: http://www.rotaryaviation.com/eficont.html
The EC-3 controller is divided into two sides, A & B. The fuel injector control and ignition outputs exit the box from a single connector via a shared relay. The controller can receive either a primary or secondary 12V power source.
A few bullet points:
- I am using a primary fuel pump and a backup fuel pump. I also have two transfer pumps.
- I have not yet sized the batteries.
- I have an existing AEC9005-201 low voltage monitor, without the relay control.
- Output of the ECU will be shown on another page, perhaps later in the week.
- I have not yet properly sized the fuses or the wires in this drawing.
My concerns:
- By the time I add strobes and position lights, I will have around 14 or 15 switches, which seems like a lot for a 650 lb. (empty weight) airplane. Is there a way I could minimize the switch count?
- I am thinking about combining the E-buss and the main power bus to reduce switch count and the number of fuse blocks. I could easily shed the loads myself.
- There seem to be a lot of components connected to the unswitched battery busses. I wonder if I should use CBs instead of fuses so I would have a shutoff during servicing.
Anything else? Your input is very welcome.
Thanks!

Do any of your electronic displays have voltage monitoring and alarm features? If so, you would not have to use that low voltage module.
I would use fuses. They have several advantages. You will not be servicing equipment very often and you can pull a fuse.

I believe the D180 does have warnings, but since I already own Bob's LV
warning gizmo, I thought I'd go ahead and use it anyway.
Thanks for the input.
