Y Motion Sensor Test
Use the Y Motion Sensor test to verify functionality of
the Machine Stitch Regulator (Y-Motion). To view lo-
cation on machine see #14 on page 7 under Back-side
Diagram B.. 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 Machine Stitch
Regulator (Y-Motion).
Main
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 assem-
bly on the machine to assure that it will easily return to
the fully extended (down) position after being com-
pressed. Also assure that the track is straight with no
dips or indentations and that it is clean and free of con-
tamination. Other causes are an unplugged or dam-
aged cable or possibly an issue with the main control
board. (Figure 38)
Press the "Main" button to return to the "Regulated" or

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
Baby Lock Crown Jewel 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. (Figure 39)
