1.4 Main Assemblies
The AFP-200 main assemblies include the CPU board, the cabinet for enclosing the
control panel, the transformer assembly, and the batteries.
1.4.1 CPU Board
The control panel circuit board contains the system’s central processing unit (CPU),
power supply, and other primary components. The CPU is delivered pre-mounted in the
cabinet. Figure 3 shows the components of the CPU board, such as terminals, LEDs,
and connectors. For details of the membrane switch panel, see Figure 2 on page 15.
