Setting up a System 450 Standard Control System

After assembling the modules, your System 450 control system is ready to connect
to power and to be set up in the control module UI.
Note: You can power on and set up your System 450 control system in the control
module UI before installing the module assembly or wiring the sensors and
outputs.
Note: The sensors and transducers must be set up in the System 450 UI before
you can set up any of the control system outputs. See Setting Up the
Sensors and Transducers on page 45 for more information and detailed
procedures.

Determining Output Numbers and Output Types

After all of the modules in your control system are properly assembled and each
time power is supplied to the module assembly, the control module automatically
polls all of the modules in the assembly, assigns output numbers, and determines
output types and their order in the assembly.
The control module assigns a sequential output number to each output in the
module assembly, starting with the output farthest to the left in the module
assembly (first expansion module), which is assigned output number 1. Each
output to the right of output 1 is assigned an output number; the numbers are 2 to 9
in order of the output's physical position, left to right, in the module assembly.
Zero (0) is assigned to output 10, if the control system has ten outputs. See
Figure 4 on page 13 for an example of output numbers in a module assembly.
The control module also determines if an output is a relay output or an analog
output, and generates the appropriate status screens and setup screens in the
System 450 UI for each output.
IMPORTANT: Do not change the module positions after a System 450 control
system is assembled, powered, and set up in the System 450 UI. System 450
control logic is set up in the UI according to the sensor type, output type, and
output number. If you change the module positions in a module assembly that is
already set up in the UI, the output numbers and default setup values for the
outputs also change, which often requires you to set up the entire control system
in the UI again.

System 450 UI Navigation Guidelines

See the example menu flowchart in Figure 3 on page 12 and the following general
guidelines for information on navigating the System 450 UI on standard control
modules.
• During normal operation, the Main screens (sensor status screens) auto-scroll,
displaying the control system's sensor statuses on the LCD.
• While the Main screens are auto scrolling on the LCD, press
manually scroll through the sensor status and output status screens.
