To change module 4:
Output Module 4 (on the Option board) is also held in place by a tie wrap.
Snip tie wrap to remove module as shown in
Photo 6.

Figure 4.3 shows a representation of an output module. Inspect the module(s)
to make sure that the pins are straight.
8. To install any module, align its pins with the holes in the circuit board, and
carefully insert the module in the socket. Press down on the module until it
is firmly seated; refer to
Photo 7.

9. Replace tie wraps for all the modules (the Retention Plate and Output Mod-
ule 4) with new ones before reassembling the controller.
Failure to use the tie wraps may result in loosening of the module and even-
tual failure. All separately ordered modules should come with a tie wrap. Extra
sets of tie wraps are available by ordering Part #535-PROF-665.
NOTE: For greatest accuracy, calibrate all milliamp modules added for
retransmission as per the instructions in Appendix 2.
10. Rejoin the circuit boards by aligning the pins of their connectors, then squeez-
ing the board(s) together. Make sure that all three printed circuit boards are
properly seated against one another; check along side edges for gaps. Make
sure the cable assemblies are not pinched.
11. To reattach the board assembly to the front face assembly, align the boards
(with the open area on top) into the slots of the font face assembly. The clips
should snap into place.
12. To reassemble the controller, properly orient the chassis with board open-
ing on top. Align the circuit boards into the grooves on the top and bottom of
the case. Press firmly on the front face assembly until the chassis is all the
way into the case.
If it is difficult to slide the chassis in all the way, make sure the screws have
been removed (they can block proper alignment), and that the chassis is
properly oriented.
13. Carefully insert and align screws. Tighten them until the bezel is seated firmly
against the gasket.
Do not overtighten.
