SV-EMS-220/221 Installation and ConfigurationLegacy Dynon-Supplied Oil Pressure Sensor (100411-002)First, mount the oil pressure sensor to a fixed location usingan Adel clamp (see Figure 34) or other secure method. Theoil pressure sensor must not be installed directly to theengine due to potential vibration problems. Dynon Avionics’sensor is supplied with a 1/8” NPT pipe thread fitting. Anadapter might be necessary for some engines. Please see themanual supplied by the engine’s manufacturer. You must useappropriate pipe fitting adapters and ensure that the case ofthe sender has a connection to ground. This is critical forfunctionality.Crimp a standard #8 ring terminal onto general purposeinput wire chosen for oil pressure. Unscrew the stud capfrom the threaded stud. Place the ring terminal on the studand secure the cap down sandwiching the ring terminal.Due to vibration issues, never connect thesensor directly to the engine.If you use Teflon tape or other seal, ensure thesensor casing still maintains a good connectionto ground.1/8-27 NPT0-150 PSIFigure 33–Example Oil PressureSensorUse an Adel clamp similar to theFigure 34–Adel Clampsabove to secure the pressure sensorRotax 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-220/221 ground is appropriate).In mid-2008, Rotax switched to a new type of oil pressure sensor made by Honeywell (RotaxP/N 956413) with an integrated cable. Connect the red wire of the newer sensor to SV-EMS-220/221 D37 pin 15 (+12 volt Auxiliary), the white wire to SV-EMS-220/221 D37 pin 6, and theblack wire (if present) to ground. Select the correct sensor type as described in the EMS SensorDefinitions, Mapping, and Settings Section.In late 2012, Rotax further switched to a new oil pressure sensor (Rotax P/N 456180). It isfunctionally identical to the previous Honeywell (Rotax P/N 956413) sensor, and connects in thesame fashion as it. However, the connector and wiring for the sensor that Rotax includes withthe engine may require some assembly. See the diagram below for the pinout of the connector.7-36 SkyView System Installation Guide - Revision O
