ITEM DESCRIPTION
Audio Volume This output can be set from “0” (minimum volume) to
“7” (maximum volume), to adjust the 500 ohm audio
output level. NOTE: Audio Volume settings made on
this screen will only affect the volume while in
diagnostics, except in units with 01/04 SW or earlier.
With these SW versions, the user should set the
volume back to the installation value when finished
with diagnostic tests.
PFT A “1” on this output changes the inputs to the
hardware monitors, allowing the software to exercise
them during PFT.
PFT Clear A “1” on this output resets the trim runaway monitor
latch.
MET/PFT Up, MET/PFT Dn, MET/PFT Arm When the PFT output is asserted (“1”), these outputs
can be used to test the MET latent switch failure
monitor, replacing the MET switch inputs from the
harness.
Normal Acceleration Test A “1” on this output causes the accelerometer to bias
its output by 5 g, allowing the interface circuitry to be
checked during PFT.
PFT Pitch Clutch A “1” on this output causes the hardware monitors to
act as if the pitch clutch were engaged, i.e. provide
autotrim and acceleration monitoring. This is used
during PFT to exercise these monitors without
actually engaging the pitch servo.
Roll Clutch, Pitch Clutch, Pitch Trim Clutch A “1” on these outputs will engage the associated
servo clutch unless power is removed form the servo
(e.g. via the AP DISC switch) or a hardware monitor
has failed that prevents clutch engagement (see
servo interface sections for details).
