SV-OAT-340 Location and InstallationProbe LocationSV-ADAHRS-20X Installation and ConfigurationThe SV-OAT-340 is designed specifically to work with the SV-ADAHRS-20X.For full redundancy, a second ADAHRS module requires its own OAT probe.The SV-OAT-340 is an outside air temperature probe. In order for it work properly, it must beable to measure air temperature accurately. Avoid exposing the probe to sources of heat thatwould interfere with outside air temperature readings such as:Direct sunlightEngine heat and exhaustAircraft interior (back side of probe)Heated air from the cabin exiting from an open window or cabin air exhaust portThe installation area should have space for a nut and wires on the back side of the probe. It isacceptable to extend or reduce the wire length if necessary. Reduce the wire length by cuttingout the desired length from the middle of the wires and splicing together the remaining ends.If there is a backup ADAHRS in the SkyView system, it is acceptable to install a backup OATprobe a few inches away from the primary probe. Consider running primary and backup OATprobe wiring together. Tape probe wire pairs together to avoid confusion later.InstallationThe following tools and materials are required for SV-OAT-340 installation:SV-OAT-340SV-ADAHRS-20XDrill with 3/8” drill bit9/16” wrenchDo not insert the pins on the ends of the OAT probe wires into the includedconnector housing until you are done running probe wiring through the aircraft.The following procedures apply to the both the primary and backup probes.On the outside of the fuselage:1. Drill a 3/8” hole at the installation location.2. Feed the wires of the probe through the hole.3. Feed the body of the probe through the hole.On the inside of the fuselage (consider getting assistance for some of the steps below becauseit may be difficult to be simultaneously on the inside and outside of the fuselage):1. Feed the nylon washer over the cable.2. Feed the nylon nut over the cable.SkyView System Installation Guide - Revision O 5-5
