SkyView System Installation Guide - Dynon Avionics

SV-EMS-220/221 Installation and Configurationo Because each individual CS-01 varies somewhat, configuring the CS-01 typicallyrequires an amps "offset" value to be utilized. SkyView provides 17 differentoffsets via different choices in the SENSOR column. These contain offsets thatrange from "-8" (offset of -8A) through "+8" (offset of +8A). If you wish the CS-01value on your SkyView EMS to display most accurately at zero current, choosethe offset that displays "0A" when zero current is flowing through system. Thiscan be done by turning off all avionics power and operating SkyView on itsbackup battery. If you wish the current to display most accurately at normalcurrent draw, choose whichever of the 17 offset values provides the mostaccurate current reading. (This will require some experimentation.)Set the name column to “AMPS” (default) or create a custom name.Carburetor Temperature SensorThe carburetor temperature sensor may be connected to any general purpose input pin on theSV-EMS-220/221’s D37, however, we recommend that it be connected to pin 23 on thisconnector.Install the carburetor temperature sensor in the venturi area at the point where ice first beginsto form. This is located after the main nozzle, before the throttle valve. You must remove theplug in the carburetor housing below the throttle valve. On four-cylinder engines which use theMarvel Schebler MA-3 carburetors, this plug is located on the forward side. On six-cylinderengines using the MA-4 carburetor, the plug is located on the rear. If your carburetor is notdrilled and tapped for the plug, you must remove the carburetor from the engine and drill outthe lead plug in the appropriate spot. Tap the hole with a ¼-28 tap. Remove all chips and burrsbefore reinstalling.Route either of the two wires to an electrical ground on the SV-EMS-22X D37 connector. Routethe other wire to the general purpose input of your choice.Note: If you are converting a Dynon D10/D100 product installation to a SkyView installation,you should remove any resistor that is connected to the existing carburetor temperaturesensor. It is not needed when used with SkyView.Rotax CHT SensorsThe Rotax CHT sensors may be connected to any general purpose input pin on the SV-EMS-220/221’s D37, however, we recommend that they be connected to pins 4 and 22 for left andright signals, respectively.Crimp bare ¼” female Faston terminals (6.3x0.8 according to DIN 46247) onto the ends of twogeneral purpose input wires on the EMS 37-pin Main Sensor Harness. Locate the left-side CHTsensor screwed into the bottom side cylinder head 2; slide the Faston connected to one of thegeneral purpose inputs onto it. Locate the left-side CHT sensor screwed into the bottom side ofcylinder head 3; slide the Faston connected to the other general purpose input onto it.SkyView System Installation Guide - Revision O 7-47
