SkyView - Dynon Avionics

SV-EMS-220 Installation and ConfigurationNow, plug each thermocouple wire into its corresponding wire on the thermocouple harness.Ensure that you match the wire color pairs on the harness to those on the thermocouple. Allthermocouple harnesses supplied by Dynon have each function (e.g., CHT1, EGT1) labeled oneach thermocouple pair.A loose probe could allow exhaust to leak. This can lead to carbon monoxidepoisoning in the cabin and/or a potential fire. Have a knowledgeable mechanicinspect the installation.The probe can come loose during flight, and could potentially come in contactwith rotating engine parts or the propeller. We suggest a safety wire to keep theprobe in place.Cylinder Head Temperature (CHT) ProbesDynon Avionics sells and supports a variety of CHT probes. All thermocouple harnesses suppliedby Dynon have each function (e.g., CHT1, EGT1) labeled on each thermocouple pair.Lycoming/ContinentalDynon Avionics sells bayonet style CHT probes (used in Lycoming and Continental engines).With each probe we sell, a bayonet adapter is included. Your specific engine manual shoulddescribe where to mount these bayonet adapters, but normally, there is a threaded hole (CHTwell) near the bottom of the cylinder close to the lower spark plug. Screw the bayonet adapterinto this hole. Screw the locking collar up or down the spring surrounding the probe such thatthe tip of the probe is pressed against the bottom of the CHT well when the collar is attached tothe adapter. Insert the CHT probe into the well and lock the collar to the adapter. Now, plugeach thermocouple wire into its corresponding wire on the thermocouple harness. Ensure thatyou match the wire color pairs on the harness to those on the thermocouples.RotaxRotax 912 engines use 2 resistive CHT probes that are included with the engine. These probesare preinstalled, but you need to route the connections from them to the SV-EMS-220. See theRotax CHT Sensors Section for information on making the physical connection to the sensor.JabiruJabiru engines require a 12 mm ring-terminal CHT probe for each cylinder. First, slide thecompression washer off the spark plug. Slide the 12 mm ring-terminal probe onto the plug.Now, slide the spark plug compression washer back onto the spark plug. Reinstall the spark pluginto the spark plug hole. Please refer to the documentation that came with your engine formore information. Now, plug each thermocouple wire into its corresponding wire on thethermocouple harness. Ensure that you match the wire color pairs on the harness to those onthe thermocouples.7-26 SkyView System Installation Guide - Revision J
