Connect the aircraft static line (airspeed) line to the port on the PT-30Alt. Be sure this line is tight. The
port is a 1/4" flare union. Care should be taken not to put excess pressure on the flexible line.
Make sure
the flexible line does not kink.
G. Other Pressure Transducer Installations:
Other pressure transducers (Hydraulic Pressure, Cabin Pressure, Cabin Altitude Pressure, etc.) have the
same form factor as the Gyro Vacuum Transducer or the Oil Pressure Transducer and should be mounted
in the aircraft in the same manner as appropriate.
Note: Any or - pressure inputs on the EDC
must be tied to a ground pin on the 37-pin connector.
2.7 Install the Interface Circuit for Annunciators:
Any Temperature or Resistive Fuel Level channel on the EDC may be used to monitor the state of a switch, relay or
output from a device. This output can be used to trigger a light (annunciator) on the MVP. Annunciator lights such
as Chip Detect, Bypass, De-ice, Pitot Heat, Fire, Fault, Exceedance, etc. can be displayed on the Main or System
screen on the MVP. To monitor a voltage, various VI-221 (Voltage Interface Units) will be required, depending on the
configuration.
