Root Issue
Sensor outputs are bad.
Sensor outputs are bad.
1. Sensor outputs bad. They
have not been opposite for
>250ms.
or
2. Mast was told to go up,
and the sensor indicates it
did not move after 8 seconds
(v7.2), or 15 seconds (v7.3).
3. Sensor is not seeing
magnet when mast is fully
retracted.
Checked at power up after
stowing. Sensor outputs are
O.K., but sensor shows
wrong polarity for nested
state.
Sensor outputs are bad.
Switch outputs are O.K., but
show wrong polarity for Well
Closed.
Both the Nested LS and the
90° LS have been detected
active at the same time. This
is an invalid condition, and
indicates a problem with one
or both sensors.
This fault is set when the
Forced Stow switch is
activated to assure the
system is not in normal
operation during the forced
stow operation.

Potential Cause
Wiring error, faulty sensor
(Vertical only) mag switch
positioning. Note: Sensor is
only active as mast tube
magnet goes by. Software
watches for direction of travel
and sensor activation to
determine if mast is "up" or
"down".
Wiring problem, defective
magnetic sensor.
1. There may be a wiring
problem, or a defective
magnetic sensor.
or
2. Defective magnetic sensor,
air supply inadequate, or
external magnet affecting
sensor.
3. Sensor not seeing magnet -
sensor needs to be re-aligned.
Board was changed or updated
while the mast was at 90°.
D7 Green = Closed
D8 Yellow = Not Closed
Switch wiring, defective switch,
board.
Both sensors indicate proximity,
one may be bad.
