Setup and Adjustments

System 450 Components
A System 450 control system consists of one control
module, one to three control sensors, and one to ten
outputs that provide analog control and/or On/Off
control. Figure 3 shows an example System 450
module assembly with two sensors and three outputs
(two analog outputs and one relay output).
Setting up a Module Assembly
To set up a System 450 module assembly:
1. Determine the controlled conditions, sensor types,
and value ranges required for your application, and
select the appropriate System 450 sensor types.
2. Determine the number and type (relay or analog) of
outputs required to control your application, and
select the appropriate System 450 control module
and expansion modules.
3. Assemble the control and expansion modules,
starting with the control module on the left.
Note: If you use a C450YNN-1 power module, it
must be plugged into the control module. Plug
remaining expansion modules to the right of the
power module.
4. Apply power to the module assembly.
You can now set up the module assembly in the control
module UI.

Setting up a Control System in User Interface
System 450 control modules have a back-lit LCD and a
four-button touch pad User Interface (UI) that enable
you to set up all of the inputs (sensors) and outputs in
the module assembly (Figure 4).
Figure 7 provides an example System 450 setup
overview that corresponds to the control system
example shown in Figure 3 and the following setup
examples and procedures.
To set up a control system in the System 450 UI:
1. Build your control system module assembly and
connect it to power. See Setting up a Module
Assembly on page 4.
IMPORTANT: Each time a module assembly is
powered ON, the control module polls all of the
modules to identify output type (relay or analog) and
assigns a sequential output number (1 to 9 [0 = 10])
to each output starting with the control module
output on the left. The output numbers identify each
output's setup screens in the UI. (See Figure 4.)
2. Access the System 450 setup screens in the UI.
See Accessing the System 450 Setup Screens on
page 5.
3. Set up the control system inputs in the UI. See
Setting up System 450 Sensors on page 5.
