At this stage I am installing one PMAG and one impulse Slick. As I intend to eventually run two PMAG's I am installing two S700 2-10 switches. After repeated efforts I still do not understand the connection on these switches at all. The question is, how do I wire the Slick to the 2-10 switch. I need to know which tabs the shield and core attach to. Thanks Chris Byrne SYDNEY ________________________________ Message 2 _____________________________________ Time: 09:58:21 AM PST US Subject: AeroElectric-List: Re: Question on Z-13 and E-Buss (Lengthy) From: "Jekyll" --> AeroElectric-List message posted by: "Jekyll" Look more closely at the Z-13/8 schematic. Notice that the E-bus bypasses the battery contactor by running through the B-bus path. Therefore, the battery contactor draw is only on the M-bus. Next, most of the loads on your B-bus are more appropriate for the other busses. Your B-bus should most likely contain only the items you want hot at all times, IE: those items you always want on, even when not operating such as your clock, hobbs, dome light (In your case, the cockpit light) or an accessory plug. Remember the purpose of your E-bus: to provide an uneventful transition from normal operations to an endurance method to safely get you where you are going with the movement of 2 switches (turn off the master/battery and turn on the alternate feed). Once you arrive, you can turn the master/battery back on and use your other systems for approach and landing with a full battery to provide the extra load capacity. Here are some specific things to consider: The chance of both alternators failing the same bag of gas is very, very remote. You will probably be starting with both the M-bus and E-bus on; no real reason to start on just the B-bus that I know of, adding that capability clutters up your B-bus (remember, there is no way to turn off your B-bus other than disconnecting the battery. If you introduce a switch, then you really don't have a B-bus. The EIS-4000 may be on the E-bus and be on for start and during the endurance flight. Some folks say the engine info is not needed for endurance flight and they are probably correct. My view is that it is a GOOD thing to have in endurance mode IF YOU CAN AFFORD IT. Wire 1 DU, the AHARS and the magnetometer to the E-bus, make sure you have an on/off switch for the EFIS per GRT recommendations. The EIS-4000 doesn't need a switch. >From the B-bus: Move the fuel pump, starter, starter contactor, second com/nav, battery contactor, EFIS 1 ADI, GMA-340, landing light, flood/cargo lights to the M-bus. Leave the clock, cockpit lights and both mags on the B-bus (P-mags are optional here because they will generate internal power over approximately 700 rpm). Check the GMA-340 to see if it has a power off default to direct feed for #1 COM/NAV. I bet it does and therefore, no power to the audio panel is needed to operate #1 com/nav on the E-bus. Consider placing the A/P on the E-bus. If you are IFR, you'll want this for safety and peace of mind. You can have "normally-off" items on your E-bus with no penalty. I have a windscreen fan on mine. It only draws .45 amps and it is a transient load, not continuous so it doesn't add into my E-bus load. I'll turn it on for short periods if my glass fogs. You didn't provide your load analysis so I don't know how you calcuated the trim. I assume you understand the trims are transient loads and don't effect your E-bus load. I'm not a GNS-480 user but I believe they have com/nav/GPS/WAAS. Look over your load numbers and see if the extra load over and above that of just the SL-30 is worth the allocation. You may decide the SL-30 is enough. It meets the FAA requirements and is an extremely powerful device. I bet you will have a backup handheld GPS when you are IFR. You can easily wire your panel to allow you to plug the handheld into the EFIS and AP through an isolator switch. In this way, you save some of your load for other items and still have your GPS and com/nav. You will lose the WAAS enabled IFR GPS but you will have VOR/LOC/GS and the EFIS enhancements of your handheld GPS to include full capability of the AP. The GTX-327 should go on the M-bus. It is not required for safe continuance of flight. The FAA has transponder-inoperative procedures. Should you really need to ident, you can turn the M-bus on for a minute to make contact. The transponder takes 1.5 amps and is almost 20% of the output from the SD-8. Save that power for more important things such as the AP. Finally, you are not limited to a total of 8 amps on your B and E-busses. Your battery will make up for any deficiencies. Say your total endurance load is 9 amps, the SD-8 will provide 8 amps and the battery will make up the extra 1 amp. Even a poor battery should be able to provide 1 amp for a tank's worth of fuel; it did start your engine after all. If you notice some problems developing down the road, you can start to remove loads from the E-bus as the need arises. Remember, the E-bus is there to provide you a no-brainer, no-sweat method to safely and quickly reconfigure your electrical system to an endurance mode with the movement of 2 switches no thinking, no troubleshooting and no calculations. I don't know the answer about configuring the SL-30 to power only receive mode. I think it has 2 power feeds, 1 for com and 1 for nav. I don't make any assertions that my observations are complete or even accurate. Just provideing another perspective that might help you. I found this part of building to be very fun and informative. It's where the learning and operational planning merge. Your methods and results may vary.
