TCAS Range Switch in the clockwise
direction increments through the
TCAS ranges and conversely
counterclockwise rotation of the TCAS
Range Switch decrements through the
TCAS ranges. The TCAS range does
not roll over when the range is at its
minimum or maximum (i. e. stops at
“15”). The TCAS ranges are “3”, “5”,
“10”, “15”, “20” and “40”, and are
annunciated on the display.
Above/Norm/Below tells the
TCAS to display traffic Above(8700
feet above & 2700 feet below), Below
(2700 feet above & 8700 feet below)
or Normal (2700 feet above & below).
The TCAS Above/Norm/Below
selection is sequenced through by
pressing the ON/OFF Switch. The
TCAS Above/Norm/Below selection is
annunciated on the display as “ ˆ ” for
Above and “ ˇ ” for Below. If both the
up and down arrows are displayed the
mode is Norm.
A maintenance check of the
transponder system and/or altitude
encoder should be performed if the
system fails the self-test function.
The KFS 578A has a display
adjust feature which allows for display
balancing with other gas discharge
displays. To utilize this mode first
place the unit in the “TST” mode by
rotating the function select knob
counterclockwise, then press and hold
the “IDT” button for three seconds.
An “A” followed by a number between
1 and 8 is displayed. Rotate the
FL/CURSOR knob to change the
number which also adjusts the
response time for the automatic
display brightness adjust to react ot
changes in ambient light levels. Push
the FL/CURSOR knob to display a “b”
followed by a number between 0 and
64. Change this number and the
display brightness by rotating the
FL/CURSOR knob. This adjustment is
typically made at initial installation for
balancing with other gas discharge
displays in the cockpit. Push the
FL/CURSOR knob again to display a
“C” plus a number between 0 and 255.
This number and the display
brightness can also be changed by
rotaiting the FL/CURSOR knob. This
adjustment is typically made after
initial installation for fine adjustment of
the display brightness. Press the
“IDT” button to exit the display adjust
mode.
