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).
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 41)

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 II 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 42)
Press the “Main” button to return to the “Regulated” or
“Manual” menu screen or the “Back” button to return
to the “More” menu screen.
