Skyview widget X'ed out

[vonbaron1]

I am trying to get the X out of the fuel pressure widget with no luck so far.  All the other widget were no problem.  Plugged in all the ranges I needed to and did the accept and save function.  I even delete the widget and started over with no joy. It has to be just missing some small setting someplace.
Going back out to give it another go while waiting.

First thing to check is the Sensor Input Mapping in the EMS Setup.

 

[vonbaron1]

Input Mapping shows the sensor as I had to select the correct one and did a save.

 

[vonbaron1]

But it still have the X through the Widget.

 

[jakej]

Can you post a picture of the Input Mapping screen ?

 

[vonbaron1]

Cannot get a image to attach here.  Tried a few different ways but NOT.

 

[vonbaron1]

Dang, it did work.

What do you see under EMS SETUP > SENSOR DEBUG DATA for that sensor? (all of the numbers on that line)

 

[dynonsupport]

Are you certain that you actually installed a Kavlico 3 PSI fluid pressure sensor for the fuel pressure sensor? Dynon Avionics does not sell this sensor (though SkyView supports it).

Depending on the specific engine, Dynon Avionics sells 5 PSI, 15 PSI, and 50 PSI Kavlico Fluid Pressure Sensors.

If you want to be definitively determine what fuel pressure sensor you did install, look at the numbers stamped on one face of the hex "nut" on the sensor. Then compare those numbers to the table in section 27 of the SkyView System Installation Guide, Revision Y.

I did double check the number on the sensor and the number works out to be the 3lb sensor. This is the correct pressure for the Jabiru 3300 per there manual. The sensor we have has a number of P4055-5025-3. No matter which sensor, I would of thought it would get rid of the X through the widget. The debug screen shows "nan" and the end, so it must be Not available. See attached.

I'd be checking the sensor wire ( not the 5volt or ground) carefully, make sure the pin is pushed fully home in the 37pin connector on the EMS module.

HTH

 

[dynonsupport]

NAN = Not A (valid) Number. SkyView is getting a voltage value that is outside the normal range for the sensor that is specified.

We agree with Jake to check the pin / sensor output wiring.

If nothing found, perhaps the sensor has failed and needs to be replaced.

Just had a wild thought - did you connect the Fuel Flow or other 12 volt wire to it ?

The White/ red stripe 5volt wire is the only one to use.

 

[vonbaron1]

I will do a double check on the pin connection at the sensor. I did tie the + & - together for the fuel flow and pressure switch but the other wires are separate as should be. I measure the voltage on the green wire of the pressure switch and had 4.9, so that's close. I am beginning to think the sensor itself is bad.

 

[jakej]

What is the voltage on the red wire at the sensor ?

 

[vonbaron1]

Voltage is 12+ or above depending on battery status. I did find out that the dealer had sent a 50lb senor instead of the 15 but actually for the Jabiru it should be 5. Not sure if that would cause the nan or not. Will get back here when the new sensor arrives.

Aha, now we know the main issue here regardless of whether you have the correct sensor or not.

Read the install instructions  & refer to my post # 12 above - connect the sensor power wire to the 5 volt  white/red striped wire from the EMS module  :
FYI - generally sensor red wires are for positive volts input & always 5volt with Dynon supplied sensors.  The exception can be fuel level (capacitance) sensors but one needs to read the instructions  & not assume anything.  You know what they say about that word  .
Sorry if I sound a bit harsh but it can be frustrating spending more time than necessary trying to analyse a 'fault' on forums by remote control, only to eventually find that the instructions were not followed properly. I'm still smiling, hope you are

 

[vonbaron1]

Oh not harsh, I just missed that one considering the pile of wires to hook up. Did make the correction today and bingo, the X across the widget went away in a flash. So many thinks to you guys for all the help. I may not be out of the woods yet but sure am closer.

Well done !! ;D
