8.1.4) LAMP SWITCH ON THREAD TENSION ADJUSTMENT BOARD
1) Switch
– For normal operation, turn the toggle switch on to turn on the indicator lamp.
– If the machine stopped after detecting a thread break, move the frame back to the location of the thread
break and restart the machine to pick up stitching (design edit).
– To set the needle bar so a specific head does not work, turn the toggle switch off.
2) Thread break detector lamp
Lamp on the thread tension adjustment board will blink if upper and lower thread break is detected,
regardless of the toggle switch status.
