Specifications

NOTICE: Before you remove the solenoid from the bracket, record the number of
threads of the solenoid that are showing beyond the solenoid bracket (or
measure the distance that the end of the solenoid protrudes from the
solenoid bracket). When the new solenoid is installed into the bracket,
position the solenoid with the same number of threads (or distance) that
you recorded in this step.
4. Loosen the solenoid locking nut then rotate the bracket off of the solenoid.
5. Replace with new solenoid by reversing the previous procedure. Adjust the
position of the solenoid into the solenoid bracket using the "thread counts" or
measurement you obtained in that procedure (see previous NOTICE).
6. Position the jump stitch bracket back in the head against the mechanical stop.
7. Rotate clockwise with a 5 mm hex wrench in the right end of the Z drive shaft to
move the heads through at least one revolution to check that no mechanical
interference occurs.
NOTE: During installation the solenoid must be adjusted properly. If you did not
adhere to the previous NOTICE, or if for some other reason, the
adjustment for the solenoid is not correct, Refer to the Jump Stitch
Adjustment procedure in Section 2 for the proper adjustments.
Color Change PCB Replacement
The Color Change PCB controls color change commands from the design and
keyboard, thread break information, the jump stitch solenoid, and the color change
motor. The color change PCB, motor, cam, and wire harnesses are located under
the covers directly behind the embroidery head tensioner assembly. To remove the
color change PCB refer to the following procedure:
1. Remove the left color change cover behind the tensioner assembly by first
loosening the top two screws then removing the side two screws as shown in
Figure 3-35.
2. Remove the two screws in the side of the right color change area cover and
remove the cover.
3. Remove the left side tensioner bracket cover.
4. Attach a static grounding strap between yourself and the color change mounting
bracket.
5. In clockwise rotation from the middle of the left side of the color change PCB,
disconnect the following 5 harnesses: jump stitch solenoid, color change motor,
10 needle color change power, 18 color interface, and 10 needle grabber.
