A typical SV-EMS-220 installation will utilize one EMS 37-pin Main Sensor Harness and one of
thermocouple wire harness. Choose a thermocouple wire harness based on the number of EGTs
and/or CHTs that need to be monitored.
The EMS 37-pin Main Sensor Harness includes a D9 connector that is wired to
pins 11, 12, and 30. This connector should be removed for SkyView installations.
Remove the connector by cutting the three wires close to the connector.
The EMS 37-pin Main Sensor Harness (Dynon P/N 100399-000) may be wired
with blue and green wires on pins 36 and 37, respectively. If you are going to use
pins 36 and 37 for a thermocouple input such as a CHT or EGT, the blue and
green wires should be removed and replaced with the appropriate type of
thermocouple wire for thermocouple functionality on pins 36 and 37. If you are
not going to use these pins for a thermocouple input, the blue and green wires
do not need to be removed.
All of the ground wires on the SV-EMS-220 D37 are interchangeable, and can be
used for any sensor that requires grounding. Additionally, one of these wires
needs to be grounded to the aircraft locally to provide a good ground reference
for the engine sensors. We suggest using the black ground wire connected to D37
pin 3 for this purpose.
Sensor and Transducer Compatibility Key
This section is primarily intended for users with installations that are not
supported in or significantly deviate from the preconfigured installation resources
available from Dynon. Reference Example Engine Sensor and Transducer
Installations Section for installations which have downloadable preconfigured
installation resources.
This section explains how to use Table 14–Sensor and Transducer Compatibility Level Key.
There are three compatibility designations: A, B, and C. These designations are explained in the
following paragraphs.
