Johnson Controls System 450 Series Installation Instructions Manual page 6

Table 3 provides information about System 450
sensors, Sensor Types, parameter values, and
specified sensor/transducer product code numbers.
Table 4 provides information, procedures, and
examples regarding Sensor Setup screens and setting
up sensors. Figure 7 provides a System 450 UI and
setup overview example.
Setting Active/Passive Sensor DIP Switches
Before putting your control system into operation, you
must set up each sensor in the system as either
passive or active by positioning the associated switch
(On or Off) on the DIP switch block located below the
sensor terminal block. See Figure 3.

LCD Screen Name, Description/Function, User Action, and Example
Sensor Setup Start Screen: The Sensor Setup Start screen is the first screen displayed when you
-- -
access the System 450 setup screens. From the Sensor Setup Start screen you can navigate to the
Output Setup Start screens or the Sensor Setup screens. See Figure 7.
SENS
Note: You must setup the input sensors before you can setup the control system outputs. The Sensor
Setup Start screen is view-only, selections are not made in setup start screens.
Press MENU (repeatedly) to scroll through the Output Setup Start screens. (See Setting up a
Relay Output (OUTR#) and Setting up an Analog Output (OUTA#) for information and procedures on
setting up outputs.)
1. Press NEXT to go to the first Sensor Type Selection screen (Sn-1) and begin setting up the
sensors in your control system.
Example shows the Sensors Setup Start screen with four flashing dashes.
6 System 450™ Series Control Modules with Analog Outputs Installation Instructions
Temperature sensors are passive (2-wire) sensors and
corresponding switches must be set to ON. Humidity
and pressure transducers are active (3-wire) sensors
and corresponding switches must be set to Off. See
Figure 5 for the switch settings for the System 450
example shown in Figure 3.
