SV-EMS-220/221 Installation and Configurationshunt. Slide the ring terminals onto them and screw them back into the base. Connect the“Amps High” lead to the side of the shunt marked by “H” in Figure 40; connect the “Amps Low”lead to the side marked by “L”.If you find that the current reading on the SkyView is the opposite polarity of what you want,swap the two signal inputs (Amps High and Amps Low) to obtain the desired result.It is extremely important that you secure all loose wires and ensure that exposedterminals cannot touch or short out to other objects in the plane. All metal on theshunt is at the same voltage as–and carries the same risks as–the positive terminalon the battery. Improperly installing the ammeter shunt can result in high currentflow, electrical system failure, or fire.GRT CS-01 Hall Effect Current SensorDynon does not supply this sensor. It is available from GRT Avionics, and can be used as analternative to the Dynon-supplied amps shunt for measuring currentNote: The GRT CS-01 sensor does not connect to Pin 24/25 (Amps Shunt +/- Input). If you areconverting from a Dynon EMS, you will have to change your wiring per the instructions below).Route the main power cable through the CS-01 "donut".

Configure the CS-01 using thefollowing instructions: Go to SETUP MENU >EMS SETUP > SENSOR INPUT MAPPING. Choose one of Pins 8, 22,23, or 31, as is physically connected above.For the “FUNCTION” column selection, choose “AMP”For the “SENSOR” column selection, choose one of the AMMETER HALL EFF (offsetvalue) (GRT CS-01), where offset value is chosen per the following:7-46 SkyView System Installation Guide - Revision O

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
