Ensure you order the correct wire type for thethermocouple you intend to use. Crimp a female D-sub pin on the end of each wire, and plugthem into the SV-EMS-220’s EMS 37-pin Main Sensor Harness DB37. Polarity is important, soensure that you are routing the positive side (yellow for K-type; white for J-type) of thethermocouple to pin 27 or pin 36 on the 37-pin harness, and the negative side to pin 28 or pin37.External EMS Warning LightSV-EMS-220 DB37 pin 29 can be wired and configured as an External Alarm LightTo wire EMS DB37 pin 29 as an External Alarm Light, you may connect any standard LED orincandescent lamp (1.5 watts maximum), used during EMS-related alarm conditions. Ensurethat the LED or lamp is designed for the voltage of your system. Mount it to your panelaccording to its recommendations. Connect one of the lamp’s leads to your plane’s power.Connect the other lead to pin 29 on the SV-EMS-200 37-pin wiring harness. During an alarmcondition, this pin is connected to ground, causing current to flow through the lamp.Aircraft Spruce P/N 17-410 is an example of a light that will work for this application. An LEDand resistor in series will also suffice. If you use an LED as the indicator, you must choose aresistor that delivers the appropriate current to the LED, and can accommodate the powerrequired for its current and voltage drop. Also note that the power and ground connections onLEDs are not reversible.Engine InformationUse the Engine Information Wizard (SETUP MENU > EMS SETUP > ENGINE INFORMATION) tospecify the engine type, its horsepower rating, its redline and cruise RPM, the RPM pulseconfiguration, and tach and hobbs time (if installation is in a non-zero time engine).If you have an engine type that is in the list, please choose the appropriate engine. This willallow the system to perform some calculations that are specific to that engine, such as % powerand special operating limitations. If your engine is not listed, choose "Other."SkyView System Installation Guide - Revision J 7-41
