To perform the Motor Sensor Test
The Motor Sensor test helps you determine whether there may be a problem with the Baby Lock Coronet
motor.
• Press the Motor Sensor Test button. Slowly rotate the handwheel. While rotating, you should hear
an audible pulsing beep. If you get a constant solid beep or no beep at all, the test has failed and
the machine should be inspected by a qualified Baby Lock retailer.
To perform the Needle Sensor Test
The Needle Sensor test indicates whether the needle position sensor is functioning properly.
• Press the Needle Sensor Test button. Rotate the handwheel. While rotating, you should hear a beep
for half of a stitch cycle followed by no beep for the other half. If you hear a constant beep or no
beep at all for a full 360° rotation of the handwheel, the test has failed and the machine should be
inspected by a qualified Baby Lock retailer.
To perform the Motor Speed Sensor Test
The Motor Speed Sensor test helps you determine whether or not there is a problem with the Baby Lock
Coronet speed sensor.
 NOTE: Before performing this test, remove the bobbin case and the top thread.
• Press the Motor Speed Sensor button. Then press the Start button on the handlebars and the
machine will begin slowly rotating. The display will show a number that should stabilize at 100 if the
sensor is functioning properly. Press Start again to stop the machine and the test.
To perform the Keypad Test
The Keypad test verifies that the Baby Lock Coronet is reading the handlebar buttons when they are
pressed.
• Press the Keyboard Test button. Then press one of the handlebar buttons. When you press the
key, the name of the key appears in a white box on the screen. When you release the key,
the name disappears.
To perform the Y-Motion Sensor Test
Use the Y-Motion Sensor test to verify functionality of the Y-axis stitch regulator encoder (the encoder
mounted to the rear power pod side machine wheel).
• Press the Y-Motion Sensor test button. Slowly move the machine toward and away from you. You
should hear a pulsing beep that pulses faster as you move the machine faster. A solid beep, no
beep, or periods of irregular beeping (with constant motion) indicate a problem with the Y-axis
encoder.
