connect the following cables (Refer to Figure 11-6):
4 40 pin ribbon cable (J3)
4 20 pin ribbon cable (J5)
4 10 pin cable (J4)
4 6 pin cable (J2).
4. Slide the control panel assembly into the control head.
5. Replace four screws (M4 Phillips) and four lock washers (M4), located
at the rear of the control head, that fasten the control panel assembly to
the control head.
6. Swivel the control head so that the front of the control panel aligns

Control Head Components
The control head contains three replaceable components:
* Machine control PCB
e Control panel overlay
* Display PCB.
The control panel overlay covers the front of the control panel (its
fasteners are accessible inside the control head). The Machine Control PCB
and display PCB (attached to a chassis) constitute two layers in a control
panel assembly within the control head (refer to Figure 11-8). Gaining
access to any of these components involves removing previous layer(s).
