SkyView System Installation Guide - Dynon Avionics

SV-EMS-220/221 Installation and ConfigurationNote that SkyView displays are typically preconfigured to use resistive probes. Using capacitivesensors instead of resistive probes requires that you change EMS settings in a few places. First,change the pins used for fuel quantity via the SETUP MENU > EMS SETUP > PIN SENSOR INPUTMAPPING… menu. Then, delete the default fuel quantity widgets from each screen layoutunder SETUP MENU > EMS SETUP > SCREEN LAYOUT EDITOR. Finally add, the new fuel quantitywidget(s) that will be available for the capacitive probes.Ammeter ShuntThe ammeter shunt should be mounted so that themetal part of the shunt cannot touch any part of theaircraft. The ammeter shunt can be installed in yourelectrical system in one of three locations as shown inFigure 40.If you have a Vertical Power VP-X system in youraircraft, use either position A or position B. Position C is not useful in a VP-X installationbecause the VP-X measures aircraft loads directly. Position A–Ammeter indicates current flow intoor out of your battery. In this position, it willshow both positive and negative currents(i.e., -60 amps to +60 amps). Position B–Ammeter indicates only the positivecurrents flowing from the alternator to boththe battery and aircraft loads.

(0A-60A)Note that the ammeter shunt is not designed for the high current required by thestarter and must not be installed in the electrical path between the battery andstarter.The Ammeter Shunt packaging may be marked 40mV/40A. However, Dynon ratesthe shunt for up to 60A loads.7-44 SkyView System Installation Guide - Revision O
