9.1.2 CA Controller Programming (Memory) Card
The programming card is used for loading the software
into the CA Controller. This is the same concept as using
a floppy diskette to load software into a personal
computer.
The software that can be loaded into the CA Controller
module combines the operational and configuration
software. Operational software enables the CA
Controller module to perform its functions. Refer to
Table 23 for Configuration parameters.
A programming card with the operational software is
available thru CTD Replacement Components Group.
The use of a programming card in the field should only
occur under unusual circumstances. Some of these
circumstances may include:
a. A CA Controller module has an older version of Op-
erational Software, and the need exists to upgrade to
a newer version of the software.
b. A CA Controller module was damaged in such a way
that the integrity or existence of software within the
module is questionable.
Procedure for loading software:
Refer to section 12.14.1, page 133.
9.1.3 General Layout of the CA Controller Section
The CA Controller consists of a key pad, display
module, start-stop switch, and a CA Controller module.
Connectors are used to attach the wiring of the unit to
the CA Controller module. The CA Controller module is
designed to permit ease of installation and removal.
All control functions are accessed by key pad selections
and viewed on the display module. They are designed
for optimum user friendliness and convenience.
The key pad (see Figure 64) is mounted on the left-hand
side of the control. The key pad consists of 11
push-energized membrane switches that act as the
user interface with the CA Controller.
