SV-EMS-220 Installation and ConfigurationIf you use Teflon tape or other seal, ensure thesensor casing still maintains a good connectionto ground.Rotax and Jabiru Oil PressureIf you are installing on a Rotax or Jabiru engine, your engine comes with a pre-installed oilpressure sensor.Prior to mid-2008, Rotax provided an oil pressure sensor with 2 tabs for electrical connection. Ifyou are using this sensor, connect one of the tabs to a general purpose input pin and connectthe other tab to ground (an SV-EMS-220 ground is appropriate).In mid-2008, Rotax switched to a new type of oil pressure sensor (Rotax P/N 956413) with anintegrated 2-wire cable. Connect the red wire of the newer sensor to SV-EMS-220 DB37 pin 15(+12 volt Auxiliary) and the white wire to SV-EMS-220 DB37 pin 6. Select the correct sensor typeas described in the EMS Sensor Definitions, Mapping, and Settings Section.Rotax oil pressure sensor P/N 956413 is only compatible with SV-EMS-220 DB37pin 6. It will not work with any other pin.Oil Temperature SensorThe oil temperature sensor may be connected to any general purpose input pin on the SV-EMS-220’s DB37, however, we recommend that it be connected to pin 7 on this connector.The oil temperature sensor needs to be installed according to the directions of the enginemanufacturer. <strong>Dynon</strong> <strong>Avionics</strong> sells oil temperature sensors with both 5/8-18 UNF (<strong>Dynon</strong> P/N100409-001) and 1/8-27 NPT (<strong>Dynon</strong> P/N 100409-000) threads. Ensure that you have the rightsensor for your engine. Using a crush washer (not included) between the sensor and the enginecase, tighten the sensor according to your enginemanufacturer’s recommendations.Route the wire from a general purpose input pin on the EMS37-pin Main Sensor Harness to where the oil temperaturesensor is mounted. When routing the wires, make sure thatthey are secured, so they will not shift position due tovibration. Strip ¼” of insulation off the end of the wire. Crimpa #10 ring terminal onto the end of the wire, ensuring that agood connection is made between the wire and theconnector. Unscrew the nut from the stud on the oiltemperature sensor. Slip the ring terminal onto the stud andsecure the nut over it.1/8-27 NPT5/8-18 UNFFigure 31–Example Oil TemperatureSensors7-30 <strong>SkyView</strong> System Installation Guide - Revision J
