SV-EMS-220/221 Installation and ConfigurationKavlico Brand Dynon-Supplied Brand Fluid Pressure Sensors (101716-000)Mount the pressure sensor to a fixed location using an Adel clamp or other secure method suchas using a transducer mounting block on the firewall. Unlike Dynon’s older fluid pressuresensors, the Kavlico sensor has a dedicated ground wire, eliminating the need to use the sensorcase as ground. Next, connect the sensor to the coolant line using appropriate hoses andfittings. Its pressure port has a 1/8-27 NPT pipe thread fitting; you may need adapters toconnect to the pressure port on your engine. Locate (or drill and tap) the pressure port alongthe coolant line. This port must have a pressure fitting with a restrictor hole in it. This restrictorhole ensures that, in the event of a sensor failure, coolant leakage rate is minimized, allowingtime for an emergency landing.Connect the red wire to SV-EMS-220/221 D37 pin 18 (red/white). This connection may beshared with other sensors, depending on your installation.Connect the green wire to SV-EMS-220/221 D37 general purpose input of your choosing.Connect the black wire to Ground. Any the black ground wires on the SV-EMS-220/221 D37harness are suitable for this purpose.Legacy Dynon-Supplied Coolant Pressure Sensor (100411-000)The Dynon-supplied coolant pressure sensor is a 0-30 psi sensor (Dynon P/N 100411-000). First,mount the pressure sensor to a fixed location using an Adel clamp or other secure method. Thepressure sensor must not be installed directly to the engine due to potential vibrationproblems. Next, connect the sensor to the coolant line using appropriate hoses and fittings. Itspressure port has a 1/8-27 NPT pipe thread fitting; you may need adapters to connect to thepressure port on your engine. Locate (or drill and tap) the pressure port along the coolant line.This port must have a pressure fitting with a restrictor hole in it. This restrictor hole ensuresthat, in the event of a sensor failure, coolant leakage rate is minimized, allowing time for anemergency landing.Crimp a standard ¼” female Faston onto one of the grounds coming from the SV-EMS-220/221’s EMS 37-pin Main Sensor Harness. Crimp another ¼” female Faston onto the wire thatcorresponds to the desired general purpose input. Push the two Fastons onto the two terminalson the fuel pressure sensor. Polarity is not important.Note: If you are converting a Dynon D10/D100 product installation to a SkyView installation,you should remove any resistor that is connected to the existing coolant pressure sensor. It isnot needed when used with SkyView.Due to vibration issues, never connect the sensor directly to the engine.If you use Teflon tape or other seal, ensure the sensor casing still maintains a goodconnection to ground.SkyView System Installation Guide - Revision O 7-49
