Setting up a Control System in User Interface
System 450 control modules have a back-lit LCD and a
four-button touch pad UI (Figure 4) that enable you to
set up your control system. 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 System 450
Module Assembly on page 4.
Note: Every 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 6.
3. Set up the control system inputs in the UI. See
Setting up System 450 Sensors on page 6.

LCD Screen Name, Description/Function, User Action, and Example
Main (Input Status) Screen: During normal operation, the Main screen automatically scrolls through the
232
current status at each input sensor in your control system and displays the sensor number, the unit of
measurement, and the sensed condition value. See Figure 7.

Note: In any system setup screen, you can return to the Main Screens by pressing both
simultaneously. Also, the UI returns to the Main screen after 2 minutes of inactivity in any screen.
Screen examples show Sensor 1 sensing 232 psi and Sensor 2 sensing 74°F.
System Status Screens: The System Status screens display current status of all inputs and outputs in
On
your control system. Relay output status screens display output number and relay status (On/Off). Analog
output status screens display output number, signal strength, and control ramp icon. See Figure 7.

4. Set up the control system outputs in the UI. See
Setting up System 450 Outputs on page 8.
IMPORTANT: Do not change the module positions
after a System 450 control system is set up in the UI.
System 450 control logic is set up in the UI according
to the Sensor Types, the output types, and the output
numbers. Changing modules or module positions in a
module assembly that is already set up in the UI, can
change the output numbers, output types, and the
setup values of the assembly outputs, which requires
setting up the outputs again.
Use the worksheet provided on page 14 to plan and
record the settings for your System 450 control system.
Viewing the Main and System Status Screens
After you install, wire, power on, and set up your control
system in the UI, the Main screens appear on the LCD.
During normal operation, the Main screens
automatically scroll through the current status of each
sensor in your control system. See Table 2 for more
information about the Main screens.
The System Status screens display the current status
of each input and output in your control system. In the
Main screen, press repeatedly to scroll through and
view all of the status screens in your control system.
See Table 2 for more information about the System
Status screens.
