SV-EMS-220/221 Installation and Configuration
SkyView System Installation Guide - Revision AA 7-61
If you have a Van’s Aircraft RV and have installed the capacitive plates fuel level sensor option,
and are installing the Dynon Avionics Capacitance to Voltage Converter for Van’s Capacitive
Plates (P/N 100654-000), instructions for installing this option can be found at Capacitance to
Voltage Converter for Van’s Capacitive Plates in Accessory Installation and Configuration.
Note that default fuel level sensor type is resistive fuel level sensors. To use capacitive fuel level
sensors instead of resistive fuel level sensors requires changes to EMS settings in a few places.
First, change the pins used for fuel quantity via the SETUP MENU > EMS SETUP > SENSOR INPUT
MAPPING… menu. Then, in SETUP MENU > EMS SETUP > SCREEN LAYOUT EDITOR, delete the
default fuel quantity widgets from the 20%, 50%, and 100% layouts. Finally, add the new fuel
level widget(s) that will be available for the capacitive fuel level sensors.
After installation, prior to use, fuel level sensors must be calibrated before they can
display accurate fuel levels. Until you have performed a fuel level calibration, the
fuel level sensor widget will not display fuel levels, and will display CAL ?
If you have installed capacitive fuel level sensors, and these sensors require their
own calibration, perform that calibration before performing the SkyView fuel level
calibration.
To perform a fuel level calibration, go to SETUP MENU > HARDWARE CALIBRATION
> EMS CALIBRATION > FUEL TANK xxx CALIBRATION > (one more right click) and
follow the on-screen instructions to perform the fuel level calibration. Generally,
you will be prompted to perform up to ten (10) fuel level pours of equal volume;
the volume of each pour will be determined by the size of the tank that you input.
For an accurate fuel level calibration, it is important to follow the on-screen
instructions exactly. For example, pushing the NEXT button before a fuel pour is
completed, or pushing it twice for one fuel pour, will result in an inaccurate
calibration, and the fuel level calibration procedure will likely have to be repeated.
Once a capacitive fuel level sensing system is calibrated for a certain type fuel, only
that fuel should be used and the aircraft should be placarded for such. For example,
ethanol has a dielectric constant much different than 100LL or Auto Fuel. If your
capacitive fuel level sensor has been calibrated for 100LL, and you then use Auto
10% Ethanol in the tanks, the fuel level indications could be off significantly.
Ammeter Shunt
The ammeter shunt should be mounted so that the
metal part of the shunt cannot touch any part of the
aircraft. The ammeter shunt can be installed in your
electrical system in one of three locations as shown in
Figure 75.
