Install the Control Panel Assembly
1. Remove ESD strap.
2. Position the control panel assembly at the control head opening.
3. Before sliding the control panel assembly into the control head, connect the
following cables (Refer to Figure 11-6):
 40 pin ribbon cable (J3)
 20 pin ribbon cable (J5)
 10 pin cable (J4)
 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.
While the screws are still loose,
take care not to let the control panel
assembly fall out of the control
head.
6.
Swivel the control head so that the front of the control panel aligns with the
front of the console.
7. Plug the power cord connector into the wall receptacle.

Control Head Components
The control head contains three replaceable components:
• Machine control PCB
• 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).
Notice
To avoid product damage, remove the ESD wrist strap before connecting cables to the
Machine Control PCB.
