– Connect Sensors
The “Connect Sensors” banner screen will be displayed next. Messages that appear on this
screen prompt you to perform the physical installation and connection of the tachometer and
vibration sensors to the input channels you specified in the applicable setup.
You must use the vibration sensor installation locations as specified by the applicable
polar charts. The orientation of the sensor is key to the accuracy of the chart, if the sensor
is installed in a direction other than that specified, the phase (clock) angles will be
incorrect and solutions will not be accurate.
If you are using a magnetic pickup for the speed sensor, install and set the gap as directed
in the applicable maintenance manual or polar chart.
It is permitted to use the Phototach for the main rotor once-per-revolution source. If using
a Phototach as the tachometer, refer to paragraph 7.2.3.1 “Optical Tachometer Setup”.
The Tracking Device will be auto-selected depending upon what is connected to the
analyzer, and will display either TraX or Strobe.
At this time install any ship’s power and strobe cables as needed. When completed, press
[OK].
