the control box with a new one.

When the signal does not change, refer to the block diagram showing
the cable connections and check to see if connection from the X cap
sensor to the main PCB is proper. Replace the X cap sensor with a
new one.
• Is the pulley manually turned and out of the stop angle?
Turn the pulley, adjust the needle at the stop position, and reset the
error.

check connection from the needle position detention sensor to the main
PCB. Replace the needle position detection sensor with a new one.
• Is the main shaft brake solenoid operating?
If not, refer to the block diagram showing the cable connections and
check to see if the connections from the brake solenoid to the power
PCB and from connector P27 of the power PCB to connector P1 of the
main PCB are proper.
