5-4) LAMP ON THREAD TENSION ADJUSTMENT BOARD

1) Switch
① For normal operation, turn the toggle switch on to turn on the indicator lamp.
② If the machine stopped after detecting a thread break, move the frame back to the location of the thread break
using STOP button and restart the machine to pick up stitching (design edit).
[NOTE]
If you want to move the frame back for any reason when a thread break has NOT occurred, press
the toggle twice (OFF and ON again).
③ To set the needle bar so a specific head does not work, turn the toggle switch off.
[CAUTION 1]
The take-up lever continues to operate even when the head is turned off. This movement can cause
the upper thread to come out of the holder. Use a rubber magnet to fix the unused upper thread.
2) Thread Break Detector Lamp
Lamp on a specific head will blink when thread break is detected at the head, while lamps on other heads will be
turned off. You cannot turn the lamp on or off on the other heads using the toggle switch.
[CAUTION 2]
Foreign substances around the thread detector roller may block smooth rotation of the roller and
cause wrong detection of thread break.
3) Deletion of Thread-Break Detection Function
Poor function of the thread detecting roller due to foreign substances around it may result in wrong and frequent
detections, causing inefficiency of work. In this case, you can turn off the detecting function by turning off the
toggle switch at the end of the thread tension adjustment board. This will turn off the detecting function on the
head you are working with.
