SV-EMS-220/221 Installation and Configuration

Use an Adel clamp
similar to the above to
secure the pressure
sensor
Oil Pressure Sensor
The oil pressure sensor may be connected to any general purpose input pin on the SV-EMS-
220/221’s D37, however, we recommend that it be connected to pin 6 on this connector.
The SV-EMS-220/221 supports several oil pressure sensor installations. The Dynon-supplied
sensor and the Rotax and Jabiru pre-installed sensors are the most common.
Kavlico Brand Dynon-Supplied Brand Oil Pressure Sensor (101693-000)
Mount the oil 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 oil pressure sensor, the Kavlico pressure sensor has a
dedicated ground wire, eliminating the need to use the sensor case as ground.
Connect the red wire to SV-EMS-220/221 D37 pin 18 (white/red). This connection may be
shared with other sensors, depending on your installation.
Connect the green wire to SV-EMS-220/221 D37 general purpose input of your choosing
(nominally pin 6)
Connect the black wire to Ground. Any the black ground wires on the
SV-EMS-220/221 D37 harness are suitable for this purpose.
Legacy Dynon Oil Pressure Sensor (100411-002)
First, mount the oil pressure sensor to a fixed location using an Adel
clamp (see Figure 37) 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.
