SV-EMS-220 Installation and Configuration
7-32 SkyView System Installation Guide - Revision K
Oil Temperature Sensor
The oil temperature sensor may be connected to any general purpose input pin on the SV-EMS-
220’s D37, 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 engine
manufacturer. Dynon Avionics sells oil temperature sensors with both 5/8-18 UNF (Dynon P/N
100409-001) and 1/8-27 NPT (Dynon P/N 100409-000) threads. Ensure that you have the right
sensor for your engine. Using a crush washer (not included) between the sensor and the engine
case, tighten the sensor according to your engine
manufacturer’s recommendations.
Route the wire from a general purpose input pin on the EMS
37-pin Main Sensor Harness to where the oil temperature
sensor is mounted. When routing the wires, make sure that
they are secured, so they will not shift position due to
vibration. Strip ¼” of insulation off the end of the wire. Crimp
a #10 ring terminal onto the end of the wire, ensuring that a
good connection is made between the wire and the
connector. Unscrew the nut from the stud on the oil
temperature sensor. Slip the ring terminal onto the stud and
secure the nut over it.
Some oil temperature sensors that SkyView supports (but
are not sold by Dynon), such as the GRT FT-LC-01, have two wires. To connect this style of
sensor, connect one wire to ground. Connect the other wire to the chosen general purpose
input.
Fuel Pressure Sensor
The fuel pressure sensor may be connected to any general purpose input pin on the SV-EMS-
220’s D37, however, we recommend it be connected to pin 8 on this connector.
Kavlico Brand Dynon-Supplied Brand Fuel Pressure Sensors (101690-000, 101716-000,
101715-000)
Mount the fuel pressure sensor securely using an Adel clamp or other method such as using a
transducer mounting block on the firewall. Dynon does not recommend mounting the sensor
directly to the engine to minimize the chance of mechanical failure of the transducer due to
engine vibration. Unlike Dynon’s older fuel pressure sensor, the Kavlico pressure sensor has a
dedicated ground wire, eliminating the need to use the sensor case as ground.
The fuel pressure sensor port has a 1/8-27 NPT pipe thread fitting; you may need adapters to
connect to the pressure port on your engine. Locate the correct fuel pressure port for your
engine. This port must have a pressure fitting with a restrictor hole in it. This restrictor hole
ensures that, in the event of a sensor failure, fuel leakage rate is minimized, allowing time for
an emergency landing.
