Top Thread Break Sensor Operation
The Top Thread Break Sensor is a useful tool for quilters who work on the pantograph
side of the machine or who use an optional computerized system such as the APQS
Quilt Path. An encoder reads the motion of the thread break sensor wheel. If the wheel
stops turning, the encoder “assumes” that the top thread has broken. You’ll hear a
short series of beeps and the Top Thread Break Indicator Light located on each Smart
Touch Pad will come on.
The machine will NOT stop sewing; the Top Thread Break Sensor is an alert system only. Turn off the sewing
motor toggle switch on any handle and re-thread your machine if necessary. The thread sensor will reset
when you stop the sewing motor to check for the thread break.
(
Using the Top Thread Break Sensor is optional, unless you wish to use the Low Bobbin Indicator.
If you are
working on the needle side of the machine where you will obviously see the top thread break, you may
choose to turn the sensor off, and then thread your machine in the standard format as indicated on page 73
in this manual.)
The Top Thread Break Sensor MUST be used if you wish to use the Low Bobbin Indicator.
Turn On the Top Thread Break Sensor.
Locate the Thread Break Sensor Switch on the machine’s top cover (on the thread path side of the machine).
Use a pen (not a pencil) or other blunt point instrument to slide the small toggle switch toward the “ON”
position. The LED light illuminates indicating the sensor is active.
NOTE: Do not be forceful with this switch as it may break. Use a flashlight to best see this switch.
