Diagnostics Tests
Motor Sensor Test
The “Motor” Sensor test can help you determine
whether they may be a problem with the HQ
18
Avanté
motor. Slowly rotating the handwheel should result
in a pulsing audible “beep.” If you get a constant
solid “beep” or no “beep” at all, this indicates a
failed test and the machine should be inspected by a
qualified Handi Quilter repair technician.
(Figure 45)
Press the “Main” button to return to the “Regulated”
or “Manual” menu screen or the “Back” button to
return to the “More” menu screen.
Needle Sensor Test
The Needle Sensor test will indicate whether the
needle position sensor is functioning properly.
Rotating the handwheel should result in a “beep” for
half of a stitch cycle followed by no “beep” for the
other half. (Figure 46)
If you hear a constant beep or no beep at all for a
full 360° rotation of the handwheel, this indicates a
failed test and the machine should be inspected by a
qualified Handi Quilter repair technician.
Press the “Main” button to return to the “Regulated”
or “Manual” menu screen or the “Back” button to
return to the “More” menu screen.
X Motion Sensor Test
Use the X Motion Sensor test to verify functionality
of the “X” stitch regulator encoder (the encoder
mounted at the rear of the carriage). As you slowly
move the carriage left and right you should hear a
pulsing “beep” that pulses faster as you move faster.
A solid beep, no beep, or periods of irregular beeping
(with constant motion) indicate a problem with the
“X” encoder. The most likely cause of a problem is a
stitch regulator wheel that is not making consistent
contact with the track. Check the spring tension on
the sensor assembly on the carriage to assure that
it will easily return to the fully extended position
after being compressed. Also assure that the track
is straight with no dips or indentations and that it is
clean and free of contamination. Other causes are
an unplugged or damaged cable or possibly an issue
with the main control board. (Figure 47)
