SV-AP-PANEL

[Langdon]

Reading the brochure for the AP controller it can also control pitch and roll trim. I am wondering if you have the Vertical Power electronic breaker system installed if the roll trim switching on the AP controller panel can talk through the SkyView system to the VP-X if it is the designated controller? If not is this a possibility for the future rather than having the secondary control though the VP page in SkyView?

Thanks,
Langdon

G'day Langdon,

I asked exactly the same thing today in the other forum, and the response was it is designed to control your trim directly, not through the VP-X.

A bit of a pain in the asre, as  I'm running a VP-X with the trim wired directly to it and talking to the SkyView through the serial connection, but i can live without the possibility of auto-trim to avoid rewiring things.

The trim controller is the same as what is in a VP-X. It takes in buttons from two sticks, and gives a trim motor output. There's nothing to "connect" between the two. The NOSE UP/DOWN buttons on the AP controller are for the AP, not the trim.

If we do auto-trim, I can't promise we will be able to use the VP-X to do this. We don't have as much control over speed and duration of trim motion via the VP-X over a serial connection as we will of our own controller.

Thanks, I will rewire as auto trim would be excellent. I'm altering the panel today and am looking forward to the new controllers.

Hi Guy's

I'm wondering the very same thing. Early days I know, without having even delivered one yet, but my assumption is that the trim control via the A/P panel would have to be autonomous and that feature on the VPX disabled.

Is there a wiring schematic available for the A/P panel. My interpretation of the instal manual pin designations on the DB15 suggests that the trim motor controls must come from the A/P panel. 

Thanks in anticipation

Hi Michael,

Yes, if you use the trim control feature of our AP Control Panel, you would not use the VPX or any other relay for trim control.

The installation guide contains a detailed description of the pinout, but we don't currently have a wiring diagram. Your assumption is correct though: wire the pilot/co-pilot trim control switches as well as the trim motors directly to the AP control panel. The enables manual trim control only currently.

For those who don't want or can't fit the AP Trim controller, I developed a 2-channel variable speed (speed scheduled) that sniffs the serial stream of a SkyView or D10x.  It also supports trim switch fault detection and correction.  FMI http://store.makerplane.org/m-pwr-2-dual-channel-variable-speed-trim-control-kit/

I've been a long time developer in the Dynon ecosystem, so I hope they don't object to this posting. It provides an elegant solution for existing or new aircraft, compatible with all Dynon EFIS systems.

Thanks, Vern Little

Vp-x has it's own speed and trim runaway setup all you need for vp-x to work as auto trim is write soft ware to do the same thing as Dynon already does. Skyview already tells you when to trim up and down and You can also manually trim the Ray Allen servo's controlled by the Vertical Power box through the Skyview panel soft keys when the vp-x is displayed on the Skyview. It appears to be fairly simple.

I've got the pitch and roll trim currently set up with the VP-X. Looking at the wiring for the SV-AP-PANEL, there doesn't seem to be any trim position information coming back to the Skyview. On the VP-X, I have the pitch and roll trim position indications. How does trim position information get back to the Skyview if it is wired up to the SV-AP-PANEL?

If I install the SV-AP-PANEL, I'm thinking I could change the servo power and control inputs over to the Skyview, and still have the position information come from the VP-X.

bruceh:

SkyView has had the capability to monitor trim position(s) for some time now (long before the existence of the SV-AP-PANEL). SkyView monitors the trim position by monitoring the potentiometer that's mechanically ganged to a trim servo - connect power, ground, and a general purpose input on the SV-EMS-220. See the SkyView System Installation Guide page 7-52.

OK, so it sounds like if I want to go install the SV-AP-PANEL and have it control the trim, I need to move the servo motor power/ground and up/down/left/right control wires over from the VP-X to the SV-AP-PANEL, but the VP-X could still provide the necessary +2.5V reference voltage and ground for the position signal potentiometers on the servos (instead of having this come from the SV-EMS). I would then need to move the position signal wire coming back from the servo to the VP-X over to an appropriate input on the SV-EMS.

Does that make sense?

The auto-trim version of this controller was announced at Oshkosh. It does not require the use of a Dynon AP controller and requires only space for a lighted pushbutton on the panel. It also provides trim switch failure detect/correct and will continue to operate (without auto-trim) if the EFIS is offline. Flight tested and available in kit or finished form. It only works with SkyView for auto-trim, but will work with the D1x for other features.

Thanks, Vern
