SV-EMS-220 Installation and Configuration
SkyView System Installation Guide - Revision K 7-31
Use an Adel clamp similar to the
above to secure the pressure sensor
Legacy Dynon-Supplied Oil Pressure Sensor (100411-002)
First, mount the oil pressure sensor to a fixed location using
an Adel clamp (see Figure 32) or other secure method. The
oil pressure sensor must not be installed directly to the
engine due to potential vibration problems. Dynon Avionics’
sensor is supplied with a 1/8” NPT pipe thread fitting. An
adapter might be necessary for some engines. Please see the
manual supplied by the engine’s manufacturer. You must use
appropriate pipe fitting adapters and ensure that the case of
the sender has a connection to ground. This is critical for
functionality.
Crimp a standard #8 ring terminal onto general purpose
input wire chosen for oil pressure. Unscrew the stud cap
from the threaded stud. Place the ring terminal on the stud
and secure the cap down sandwiching the ring terminal.
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 good connection
to ground.
Rotax and Jabiru Oil Pressure
If you are installing on a Rotax or Jabiru engine, your engine comes with a pre-installed oil
pressure sensor.
Prior to mid-2008, Rotax provided an oil pressure sensor with 2 tabs for electrical connection. If
you are using this sensor, connect one of the tabs to a general purpose input pin and connect
the 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 an
integrated cable. Connect the red wire of the newer sensor to SV-EMS-220 D37 pin 15 (+12 volt
Auxiliary), the white wire to SV-EMS-220 D37 pin 6, and the black wire (if present) to ground.
Select the correct sensor type as described in the EMS Sensor Definitions, Mapping, and
Settings Section.
Rotax oil pressure sensor P/N 956413 is only compatible with SV-EMS-220 D37 pin
6. It will not work with any other pin.
