Penn System 450 Series Installation Manual

Application
Important: Use this System 450™ Series Control
Module with Analog Outputs only as an operating
control. Where failure or malfunction of the System
450 could lead to personal injury or property damage
to the controlled equipment or other property,
additional precautions must be designed into the
control system. Incorporate and maintain other
devices, such as supervisory or alarm systems or
safety or limit controls, intended to warn of or
protect against failure or malfunction of the System
450 Module.
Important: Utiliser ce System 450 Series Control
Module with Analog Outputs uniquement en tant
que dispositif de contrôle de fonctionnement.
Lorsqu'une défaillance ou un dysfonctionnement
du System 450 risque de provoquer des blessures
ou d'endommager l'équipement contrôlé ou un
autre équipement, la conception du système de
contrôle doit intégrer des dispositifs de protection
supplémentaires. Veiller dans ce cas à intégrer de
façon permanente d'autres dispositifs, tels que
des systèmes de supervision ou d'alarme, ou des
dispositifs de sécurité ou de limitation, ayant une
fonction d'avertissement ou de protection en cas de
défaillance ou de dysfonctionnement du System 450
Module.
System 450 is a family of modular, digital electronic
controls that you can easily assemble and set up to
provide reliable temperature, pressure, and humidity
control for a wide variety of HVACR and commercial and
industrial process applications.
You can use the System 450 control modules to configure
custom application-specific control systems with up
to three input sensors and 10 (relay, analog, or both)
outputs, including control systems that can monitor and
control temperature, pressure, and humidity applications
simultaneously.
You can easily install and quickly configure a stand-
alone System 450 control module and sensor in the field
as a replacement control for almost any temperature,
pressure, and humidity control.
C450CPN-4 and C450CQN-4 models are analog output
control modules with LCD and a four-button touchpad UI
for setting up a System 450 control system. C450CPN-4
models provide one self-selecting analog output, and
C450CQN-4 models provide two self-selecting analog
outputs.
Refer to the System 450 Series Modular Control Systems with
Standard Control Modules Technical Bulletin (LIT-12011459)
for more detailed information on designing, installing,
setting up, and troubleshooting System 450 Series control
systems.

Location considerations
Observe the following System 450 location guidelines:
• Ensure that the mounting surface can support the
module assembly, mounting hardware, and any user-
supplied panel or enclosure.
• Mount the modules upright and plugged together in a
horizontal row where possible. See Figure 3. It is best
practice to mount the module with a DIN rail.
• Mount modules on flat, even surfaces.
• Allow sufficient space for wires and connections.
• Mount the modules in locations free of corrosive
vapors. Observe the ambient operating conditions
listed in the System 450 Series Control Modules with
Analog Outputs technical
• Do not mount the modules on surfaces that are prone
to vibration or in locations where radio frequency or
electromagnetic emissions may cause interference.
• Do not install the modules in airtight enclosures.
• Do not install heat-generating devices in an enclosure
with the modules that may cause the temperature to
exceed the ambient operating limit.
