Diagnostics Tests
Motor Sensor Test
Th e "Motor" Sensor test can help you determine
whether there may be a problem with the Baby Lock
Crown Jewel 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
qualifi ed Baby Lock repair technician. (Figure 34)
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
Th e 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
35 on next page.)
