Procedures:
The procedure tables that follow list the steps required to replace the old Printed Wiring Board in
your controller with the one supplied in this kit.
Table 1: How to Remove the Chassis
Step
Action
1
Remove any screws in the front face.
2
Insert a flat-bladed screwdriver into the tabs of the case as shown in
Figure 1 and pry chassis forward slightly until the chassis connectors
separate from the back of the case.
3
Grasp the bezel and pull the chassis out of the case.
Figure 1: Chassis Removal
Using a thin screwdriver, gently pry the side tabs from the front face and twist the screwdriver
slightly to disengage the front. Pry just enough to release it, otherwise you’ll bend or break
the tab. If you break or bend the tab and can’t reattach the front securely, you’ll need to reattach
the front using the 4 NEMA4 screws provided.
Insert thin screwdriver under
tabs and gently pry the tab and
twist slightly to disengage front.

Find J8 in Figure 2. Remove all wire connectors from J8 by sliding a small screwdriver
under each connector and lift the release.
3
Separate the chassis frame at the release points shown in Figure 3 and ease each
printed wiring board out of its socket on the display/keyboard assembly. Pull all boards
out of the chassis.
4
Lay the boards flat on a static-free surface. If the Display/Keyboard is to be replaced, go

8
Reinstall the Aux.Out/DI/Communications board, if present, onto the MCU/Input board
and install these as a unit into the Chassis. Make sure the connections to the
Display/Keyboard assembly are made and that the release points on the chassis snap
into place on the printed wiring boards. If the boards are not properly inserted, then the
Chassis will not slide into the Case properly.
9
Reinstall the wires onto the J8 connectors.
10
Slide the printed wiring boards back into the chassis. Make sure the connections to the
display/keyboard assembly are made and that the release points on the chassis snap
into place on the printed wiring boards.
11
Reinstall the chassis into the case. Push in hard until the case tabs lock onto the
chassis, then replace the screws, if present.
Table 6: Display / Keyboard Replacement Procedure
Step
Action
1
Remove the chassis from the case. (Figure 1)
