Meaning
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
Not Used
Sensor outputs are bad
Switch outputs are O.K.,
but show wrong polarity
for Well Closed
Root Issue
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°
Not Used
D7 Green = Closed
D8 Yellow = Not Closed
