Motor Speed Sensor Test
The “Speed” Sensor test can help you determine whether
or not there is a problem with the HQ Avanté speed
sensor. Before performing this test, remove the bobbin
case and the top thread. Press the “Start” button and the
machine will begin slowly rotating. The white box will
show a number that should stabilize at 100 if the sensor is
functioning properly. Pressing “Start” again will stop the
machine. (Figure 49)

“Manual” menu screen or the “Back” button to return to

Y Motion Sensor Test
Use the Y Motion Sensor test to verify functionality of the
“Y” stitch regulator encoder (the encoder mounted to the
rear power pod side machine wheel). As you slowly move
the carriage toward and away from you, 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 “Y”
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 machine to assure that it will easily
return to the fully extended (down) 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 50)
Press the “Main” button to return to the “Regulated” or
“Manual” menu screen or the “Back” button to return to
the “More” menu screen.
Keypad Test
The Keypad test allows the user to press any of the four
keys on the front or back handles to verify that the HQ
18
Avanté is reading the buttons as they are pressed. When
a key is pressed the name of the key that is pressed will
appear in the white box. When it is released, the name
will disappear. Perform this test on the rear display for
the rear keys, and the front display for the front keys.
