Table 3: System 450 Startup Screen, Main Screens, Status Screens, and Setup Start Screens Information
and Procedures (Part 1 of 2)
LCD Screen Name, Description or Function, User Action, and Example
Startup Screen: When you power a System 450 control module, the LCD displays the control module's
current firmware version for approximately 5 seconds before it displays the Main (Input Status) screen.
The screen example shows System 450 firmware version number 2.00 on the top of the screen. The
number on the bottom of the screen (indicated in this example with xxxx) identifies the Johnson Controls
firmware.
Main (Input Status) Screens: During normal operation, the Main screens automatically scroll through the
current status of each input sensor in your control system and display the sensor number, the unit of
measurement, and the sensed condition value. See Figure 6 for an example of the Main screens.
Note: Main screens are view-only; selections are not made in Main screens. The Main screens are the
System 450 default screens. After 2 minutes of inactivity in any screen, the UI reverts to the Main screens.
While the Main screens are scrolling, you can press repeatedly to scroll through and view the System
Status screens for all inputs and outputs in your control system.
While the Main Screens are scrolling, you can press and hold and for 5 seconds to access your
control system's Setup Start screens. But if the System 450 User password is set to a value other than
factory-default value of 0000, the Password Protected Access screen appears and requires you to enter
either the valid User password or valid Admin password to proceed to the Sensor Setup Start screen and
the rest of the System 450 setup screens.

The top two screen examples show Sensor 1 sensing 232 psi and Sensor 2 sensing 74°F. The third

System Status Screens: The System Status screens display current status of all inputs and outputs in your
control system. System Status screens are view-only; selections are not made in Status screens. Relay
output status screens display output number and relay status (On/Off). Analog output status screens
display output number, output signal strength (as a percentage of the total signal strength), and a control
ramp icon, which indicate the output's control action.
Press repeatedly to scroll and view the System Status screens for the inputs and outputs in your control
,
system. When you stop pressing the displayed Status screen refreshes its value and remains displayed
for 2 minutes before returning to the Main Screens.
The screen examples show Output 1 relay is On and Output 3 signal strength is 61% of the total signal
strength. The control ramp icon in the bottom screen example indicates that the analog output is set up with
SP<EP and OSP<OEP. See Setting Up an Analog Output for information about ramp icons.
