14.2 Pressure sensors
The iris EFIS incorporates a variety of delicate pressure sensors. Since these are zero-flux
sensors (there is no airflow through the sensors, only pressure differences), no air filters are
required.
Static pressure sensors
have an operating range of 0 to 1200 mbar, with a high resolution of
20cm of altitude. Any overpressure could damage the static pressure sensor permanently,
which is why great caution should be exercised when setting up and testing the pitot-static
system. If the total pressure were to be connected to the static port, and a pilot was to check
the IAS reading by blowing into the pitot tube, damage could easily occur.
The differential pressure sensor
has an operating speed of up to 325 km/h (50hPa). Flying
over this speed, or applying the equivalent pressure, may damage the sensor permanently.
14.3 Display
If your plane has a canopy that opens upwards, leaving the canopy open in the sun is known to
have a magnifying glass effect, concentrating the sun rays to a smaller area. This can damage
the internals of your cockpit, as well as the display of the iris EFIS. Applying excessive heat
will make the coating of the display start to become yellow and bubble (best case scenario),
or destroy the device completely. This is why it is prudent to always have your canopy, covered
from direct sunlight.
14.4 RJ connectors
RJ connectors (RJ12 and RJ45) on the back of the iris EFIS are used for connecting external
devices. If the cable is pulled out, without pressing the plastic security pin, the internals of the
iris EFIS’ connector may break and get ripped out. One should always be careful when taking
the cable out, to press the security pin completely.
14.5 MicroSD card reader
The iris EFIS features a microSD card reader on the front of the device. The microSD should
always be inserted carefully, not to miss the internal microSD card reader electronics.
14.6 Reverse polarity on power
Although the iris EFIS has diodes protecting it from reverse polarity on the main power lines,
one should note the RJ connectors are not protected and internal electronics could still get
damaged, if a power supply is connected to the wrong pins on the RJ connectors. Similarly,
the iris EFIS can damage external devices, if a wrong cable is used for connection, as the iris
EFIS provides a 12VDC power supply to the CAN, Flarm and User ports.
