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 III 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 51).
Press the “Main” button to return to the “Regulated” or
“Manual” menu screen or the “Back” button to return to
the “More” menu screen.
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 on the side of the machine. See
Figure 3 on page 15). 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” en-
coder.
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 contamina-
tion. Other causes are an unplugged or damaged cable
or possibly an issue with the main control board
(Fig-
ure 52)
.
Press the “Main” button to return to the “Regulated” or
“Manual” menu screen or the “Back” button to return to
the “More” menu screen.
