•
Select only System 450 compatible sensors. See Table 2 on page 16 for a
complete list of System 450 sensor types and models that are compatible with
standard control modules. See Table 12 through Table 20 and
on page 62 for more information on System 450
compatible sensors.
•
Select only the sensors that match the desired conditions and units of
measurement, and are designed to operate in the ranges that your control
system is intended to monitor and control.
•
Ensure that the correct sensor is wired properly to the correct input terminals
on the control module. See
•
Ensure that the wire length between the sensors and control module is as short
as possible/practical, and ensure that the wiring is properly sized. Refer to the
sensor installation instructions referenced in
for more information on wiring sensors.
•
Ensure that the correct sensor type is selected in the System 450 UI for each
sensor wired to the control module. See
•
Ensure that the active/passive switches or jumpers are set correctly for each
sensor in your control system. See
more information.
•
Ensure that each output references the correct sensor in the System 450 UI. See
on page 40.
Assembling System 450 Modules
After selecting the System 450 components for your control system, you must
assemble the modules. Figure 4 on page 13 shows an example of a System 450
module assembly.
Observe the following guidelines when assembling System 450 modules:
•
Always locate the control module on the left side of the module assembly.
•
Always plug the System 450 power module (when used) into the right side of
the control module.
•
Plug the expansion modules together, in any order, on the right side of the
System 450 power module or on the right side of the control module when an
external 24 VAC power supply is used instead of a System 450 power module.
(See
on page 37 for information on wiring an
optional external 24 VAC supply power to System 450 control systems that do
not include a power module.)
