screen to go to the first output setup

for the procedures for setting up outputs.)
Note:
You
must
set up the sensors and transducers in the System 450 UI before
you can set up the outputs in the UI.
In any of the system setup screens, press
to return to the setup start screen. In the
setup start screen, press and simultaneously or wait two minutes to return to
the Main screens.
Setting Up the Sensors and Transducers
To set up the sensors and transducers in your control system, you must select the
correct Sensor Type in the System 450 UI for each sensor and transducer used in
your application. You can also select an optional temperature offset value for any
temperature sensor that is set up in your control system.
Note:
System 450 compatible sensors consist of temperature sensors, humidity
sensors, and pressure transducers. The term
sensor
refers to all System 450
compatible input devices including transducers, unless noted otherwise.
The Sensor Type you select for a sensor or transducer automatically determines the
condition type, unit of measurement, minimum differential, setup value ranges,
and default setup values for each output in your control system that references the
sensor.
Standard control modules:
•
support temperature sensors, pressure transducers, and humidity sensors
•
support configuration of Sn-1, Sn-2, and Sn-3 for any supported Sensor Type
•
support the functional sensors HI-2 and HI-3 for the High Input Signal
Selection feature on models with Version 2.00 or later firmware
•
support the functional sensor Sn-d for the Differential Control feature on
models with Version 2.00 or later firmware
•
require Sn-1 and Sn-2 to be the same Sensor Type to set up the functional
sensors HI-2 and Sn-d
•
require Sn-1, Sn-2, and Sn-3 to be the same Sensor Type to set up the
functional sensor HI-3
Note:
For a System 450 control system to operate properly, you must wire the
correct sensor or transducer model to the correct sensor input terminals on
the control module, and select the correct Sensor Type in the associated
Select Sensor Type screen in the System 450 UI. You must also correctly
set the active and passive sensor jumpers or switches on the control
module. See Table 2 on page 16 for System 450 Sensor Types and their
associated values and settings. See
for more information on setting the active/passive switches and jumpers.
