Diagnostics Tests
Motor Sensor Test
The Motor Sensor test can help you determine whether
they may be a problem with the Baby Lock Tiara III
motor. Slowly rotating the handwheel should result in
an 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 your authorized Baby Lock
retailer. (Figure 41).
Needle Sensor Test
The 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 42).
If you hear a constant beep or no beep at all for a full
360° rotation of the handwheel, this indicates a failed
test and the machine should be inspected by your
authorized Baby Lock retailer.

or not there is a problem with the Baby Lock Tiara III

box will show a number that should stabilize at 100
if the sensor is functioning properly. Release the foot
pedal to stop the ma chine (Figure 43).
