Dynon Avionics SkyView Classic - Tools and Equipment Required; Voltmeter Inputs; Exhaust Gas Temperature (EGT) Sensors

SV-EMS-220/221 Installation and Configuration
7-44 SkyView System Installation Guide - Revision AA
Engine Monitor readings by having a good ground will also lead to a healthier aircraft electrical
system overall.
Tools and Equipment Required
The following list contains commonly used tools and equipment, however some of the tools or
equipment listed below may not apply to your installation.
 Wire strippers
 22 AWG wire
 DSUB pin crimper
 Faston/ring terminal crimp tool
o Available – http://bandcspecialty.com – (316) 283-8000 – part number RCT-1
 Weather Pack crimp tool (common slip joint pliers will also work)
o Available from http://www.whiteproducts.com/tools.shtml
 #2 Phillips screwdriver
 Flathead screwdriver
 ¼” ID tubes, any necessary adapters, and clamps for routing manifold pressure to the
sensor.
 Drill and 1/8” bit
Voltmeter Inputs
Pins 1 and/or Pin 2 of the EMS D37 connector can be used to monitor voltage in your electrical
system (or any other DC voltage source) from 10-30V DC. Connect either of the pins to a point
in your electrical system that you wish to monitor.
Exhaust Gas Temperature (EGT) Sensors
Wire length of CHT/EGT harnesses supplied by Dynon Avionics is not critical. It is
acceptable to cut the thermocouple (brown) wire of the CHT/EGT harness to
shorten the appropriate length for your installation. It is recommended to not cut
the “armored” portion of the cable near the sensor end of the CHT or EGT sensors.
The EGT wire may be extended provided that:
1) Type K thermocouple is used for the extension wire. (This is different than CHT
wire.)
2) There is no temperature change across the connection between the junction
that is created. For example, do not create a junction across the firewall.
If either of the above guidelines are not followed, your EGT readings will be
incorrect.
Correct placement of EGT sensors on the exhaust manifold - per the engine manufacturer’s
guidance - is critical to obtaining accurate readings. Placement differs between engine types
and even specific models. All thermocouple harnesses supplied by Dynon Avionics have each
function (e.g., CHT1, EGT1) labeled on each thermocouple pair.
